U.S. Space Force Satellite Catalog Reaches Six-Digit Numbers

The U.S. Space Force’s authoritative satellite catalog entered a new era on July 11, 2026, when newly assigned catalog numbers advanced from the five-digit sequence ending at 69,999 directly to six-digit catalog number 100,000. Space-Track announced the change and advised users to review its Alpha-5 information and frequently asked questions to ensure that Two-Line Element (TLE) and Three-Line Element (3LE) parsers, along with API queries, remain compatible with the expanded numbering system. The milestone marks the beginning of permanent six-digit catalog numbers for newly cataloged space objects.

The milestone was reached with the cataloging of Saramago, also known as Lusíada 3, one of four Portuguese communications satellites developed by LusoSpace. Named in honor of Nobel Prize-winning author José Saramago, the satellite is part of the Lusíada constellation, which uses Automatic Identification System (AIS) and VHF Data Exchange System (VDES) technology to improve maritime safety, vessel tracking, weather reporting, and ocean data services. The transition occurred one day earlier than CelesTrak had predicted.

Although the traditional TLE format has served the satellite community for decades, its fixed-field design was never intended to accommodate six-digit catalog numbers. Space-Track is maintaining compatibility through its Alpha-5 encoding system, while CelesTrak will distribute General Perturbations (GP) data for catalog numbers 100,000 and above using modern formats such as JSON, XML, CSV, and Key-Value Notation (KVN). These newer formats also eliminate the long-standing two-digit year limitation inherited from the legacy TLE format.

CelesTrak began supporting the modern GP formats in May 2020, giving software developers several years to prepare for the eventual transition. AMSAT likewise anticipated the change by introducing GP data distribution through its Orbital Elements service. Joe Fitzgerald, KM1P, AMSAT Orbital Elements Manager, announced that AMSAT would provide orbital elements in JSON, XML, and KVN formats while continuing to publish traditional TLE bulletins indefinitely for satellites cataloged before the six-digit transition.

For most amateur satellite operators, the change will be largely transparent when tracking existing satellites. However, software that assumes all catalog numbers contain no more than five numeric digits may require updates before it can process newly cataloged spacecraft. Developers and operators of satellite tracking applications, automated ground stations, and custom scripts are encouraged to verify compatibility with Alpha-5 encoded TLEs or one of the newer GP data formats.

While the transition may appear to be a simple numbering change, it represents one of the most significant updates to satellite orbital data distribution in decades. As launch rates continue to increase and the number of tracked satellites and debris objects grows, six-digit catalog numbers and modern orbital data formats will ensure the U.S. Space Force’s authoritative satellite catalog continues to support both the amateur and professional space communities for years to come.

NASA’s New Horizons Spacecraft Awakens from Record Hibernation

NASA’s New Horizons spacecraft has awakened from its longest hibernation period ever and resumed active operations as it continues its pioneering exploration of the Kuiper Belt beyond Pluto. Flight controllers confirmed on June 23 that the spacecraft had safely emerged from a 321-day hibernation that began on Aug. 7, 2025. Now approximately 5.9 billion miles (9.5 billion kilometers) from Earth, New Horizons remains healthy and is preparing to return stored science data collected during its dormant period. The spacecraft continues to operate far beyond Pluto as one of humanity’s most distant active planetary science missions.

The successful wake-up demonstrates the remarkable reliability of autonomous spacecraft operations across the vast distances of the outer solar system. Commands directing the spacecraft to awaken were uploaded nearly a year earlier before New Horizons entered hibernation. Because radio signals now require approximately 8 hours and 52 minutes to travel one way between Earth and the spacecraft, confirmation of the wake-up reached mission controllers through NASA’s Deep Space Network station near Madrid, Spain, nearly nine hours after it was transmitted. Such long communication delays require the spacecraft to perform routine operations independently while awaiting instructions from Earth.

Mission teams periodically place New Horizons into hibernation during extended cruise phases to conserve onboard resources and reduce operational demands while continuing valuable scientific observations. During hibernation, operators do not send routine commands or retrieve stored data, but the spacecraft continues collecting measurements using several science instruments. Throughout the 321-day hibernation period, New Horizons transmitted a weekly health-status beacon indicating that all systems were functioning normally. According to Mission Operations Manager Alice Bowman, every weekly status report received during the hibernation period was “green,” confirming the spacecraft remained in excellent health.

With the spacecraft once again fully operational, engineers will first review spacecraft health and safety data before beginning the download of scientific observations collected during hibernation. The Alice ultraviolet spectrograph will soon begin new observations of hydrogen gas in the outer heliosphere, while the Solar Wind Around Pluto (SWAP) instrument, the Pluto Energetic Particle Spectrometer Science Investigation (PEPSSI), and the Venetia Burney Student Dust Counter continue monitoring the space environment in the distant reaches of the solar system. The mission team is also completing upgrades to ground-system software that will simplify long-term spacecraft operations.

Engineers have also updated the spacecraft’s onboard autonomy software to support operations even farther from the Sun. The improvements account for the gradual decline in electrical power produced by New Horizons’ radioisotope power system and the steadily increasing communications delay as the spacecraft travels deeper into interstellar space. These enhancements will allow the spacecraft to continue conducting scientific observations with minimal intervention from Earth while remaining responsive to changing mission conditions.

Launched in January 2006, New Horizons became the fastest spacecraft ever launched at the time and completed a gravity-assist flyby of Jupiter in 2007 before making humanity’s first close exploration of Pluto in July 2015. The spacecraft later performed the first flyby of a Kuiper Belt object, Arrokoth, on Jan. 1, 2019, and has continued studying the Kuiper Belt, the outer heliosphere, and the space environment beyond the planets. More than two decades after launch, New Horizons continues expanding our understanding of the outer solar system while demonstrating the remarkable capabilities of long-duration deep-space communications and autonomous spacecraft operations.

Scientists Building Massive Deep Synoptic Array in Nevada Desert

A new radio telescope planned for Nevada could dramatically change how astronomers observe the radio universe. The Deep Synoptic Array (DSA), a project led by the California Institute of Technology (Caltech), recently passed its final design review, clearing the way for construction of what researchers describe as the most sensitive radio telescope ever built.

When completed, the array will consist of 1,650 radio dishes spread across an area approximately 12 by 10 miles (20 by 16 kilometers). The telescope is designed to combine the sensitivity normally associated with giant single-dish observatories with the sharp imaging capabilities of large interferometer arrays. Science operations are expected to begin near the end of the decade.

Researchers say the DSA will survey the sky at a pace far beyond existing radio observatories. Current radio telescopes have collectively identified approximately 20 million radio sources, but project scientists estimate the DSA could detect a similar number during its first day of operation. Over the course of its initial survey, the telescope is expected to catalog nearly one billion radio-emitting objects.

Among the telescope’s most ambitious goals is the study of fast radio bursts, pulsars, black holes, and other transient phenomena. The system will continuously monitor large portions of the sky, allowing astronomers to rapidly locate brief events that might otherwise be missed. The telescope is also expected to support follow-up observations of gravitational-wave detections and could discover more than 20,000 previously unknown pulsars.

A key feature of the project is a real-time processing system that developers describe as a “radio camera.” Rather than recording massive quantities of raw data for later analysis, the system will create science-ready radio images as observations are collected. This approach dramatically reduces storage requirements while allowing observations to be shared quickly with researchers around the world.

The Deep Synoptic Array also incorporates several unusual engineering solutions aimed at reducing costs while maintaining performance. Among them is the use of specially modified aluminum cake pans manufactured by the bakeware company Fat Daddio’s as components within the antenna feed system. Combined with room-temperature receivers, GPU-based processing, and a high-speed fiber-optic network, the innovations demonstrate how modern radio astronomy increasingly relies on advances in both computing and manufacturing to explore the universe.

Changes to AMSAT TLE Distribution for July 17, 2026

Two Line Elements or TLEs, often referred to as Keplerian elements or keps in the amateur community, are the inputs to the SGP4 standard mathematical model of spacecraft orbits used by most amateur tracking programs. Weekly updates are completely adequate for most amateur satellites. TLE bulletin files are updated daily in the first hour of the UTC day. New bulletin files will be posted immediately after reliable elements become available for new amateur satellites. More information may be found at https://www.amsat.org/keplerian-elements-resources/.

+ This week there are no additions or deletions to the AMSAT TLE distribution.

General Perturbations Data Support

AMSAT is pleased to announce that modern forms of what are called General Perturbations data are being disseminated via modern formats including JSON, XML and KVN at https://newark192.amsat.org/gpdata/current/. The reason this change is being made is that we are running out of 5-digit catalog numbers and the TLE format is not viable for satellites launched after July of this year. See https://celestrak.org/NORAD/documentation/gp-data-formats.php for details.

These data are presently considered in beta test for the next two months while hosted on the test server newark192.amsat.org, and we are very open to community feedback at webmaster [at] amsat.org. Testers may experience outages and errors while we make improvements. We intend to put this into production on our main web server in July as we expect that satellites launched after this summer will require one of the new formats to accommodate longer object numbers. AMSAT will continue to publish TLE bulletins for satellites launched before July 2026 indefinitely.

+ NASA astronaut Anil Menon and Roscosmos cosmonauts Pyotr Dubrov and Anna Kikina launched aboard the Soyuz MS-29 spacecraft from the Baikonur Cosmodrome in Kazakhstan on July 14. The Soyuz rocket lifted off at 1447 UTC and successfully placed the crew into orbit for a fast rendezvous with the International Space Station. The spacecraft docked with the ISS after a two-orbit flight, where the trio joined the station’s Expedition crew. Menon is making his first spaceflight, while Dubrov and Kikina are each beginning their second missions to the orbiting laboratory. The crew is expected to spend approximately eight months aboard the ISS conducting scientific research and supporting station operations. Menon’s research will include experiments in semiconductor crystal growth and AI-assisted medical ultrasound techniques that could benefit future long-duration space missions. (ANS thanks Space.com for the above information)

+ The U.S. Federal Communications Commission (FCC) has authorized Reflect Orbital to launch its experimental Eärendil-1 satellite, which will test the use of a large reflective film to redirect sunlight onto selected areas of Earth during nighttime. Operating from a planned 625-kilometer low Earth orbit, the technology demonstration will evaluate whether an 18-meter reflector can briefly illuminate areas several kilometers across. Reflect Orbital says the concept could eventually support emergency response, remote construction projects, and nighttime solar energy applications. The proposal has drawn criticism from astronomy organizations and dark-sky advocates, who warn that reflected sunlight could increase light pollution, interfere with astronomical observations, and affect wildlife. The FCC noted that the authorization applies only to a single experimental satellite and that any future constellation would require additional regulatory approval. If successful, the mission could open the door to a new class of space-based illumination systems while renewing debate over their impact on the night sky.

SpaceX Launches Transporter-17 Amid Concerns About the Future

SpaceX launched the latest in its Transporter series of rideshare missions July 7 as industry concerns increase about the program’s future.

A Falcon 9 lifted off from Vandenberg Space Force Base in California at 0712 UTC on the Transporter-17 mission to sun-synchronous orbit. The mission carried 81 payloads, according to SpaceX, including MarmotSat, a 3U CubeSat designed and built by students at the University of Victoria, Canada; MARINA, a cubesat built by Technical University of Košice, Slovakia; HADES-E2, a 1.5P PocketQube from AMSAT-EA; KOSTKA, a 1U Cubesat from Brno University of Technology, Czechia; and Maveric 3U CubeSat from the University of Southern California.

MarmotSat carries a VHF digipeater uplink and downlink on 145.875 MHz; a CW telemetry beacon on both 145.875 MHz and 29.410 MHz; and a DVB-S2 digital video beacon and a linear-frequency-modulation sounding downlink, both on 29.410 MHz in the 10-meter amateur satellite allocation. A separate telemetry, tracking and command subsystem operates on 436.125 MHz. (See AMSAT News Service bulletins ANS-186 from July 5 for details.)

MARINA serves as an experimental communication platform providing global HAM operators with an active digital transponder and Earth-imaging capabilities. The transponder supports GFSK AX.25 G3RUH 9600 Baud communication. It also transmits Earth observation images utilizing the robust SSDV (Slow Scan Digital Video) protocol. It has a VHF downlink at 145.925 MHz for digital transponder and telemetry, as well as a UHF downlink at 436.680 MHz for SSDV transmissions, CW beacon, and SatNOGS integration.

HADES-E2, also known as UNNE-1B, was built in cooperation with Universidad de Nebrija. It carries an SDR-based FM and FSK repeater. It also broadcasts a Codec2 digital voice message and includes an educational “guessing game” where clues are hidden weekly in its telemetry. Frequency coordination is in progress, but AMSAT-EA has proposed a 145.925 MHz uplink for modes: FM voice (no subtone) and FSK 200 bps, AFSK, AX.25, APRS 1200/2400 bps, and a 436.888 MHz downlink for modes: voice FM, CW, FSK 200bps-2400bps.

KOSTKA has a UHF downlink at 436.870 MHz for 9k6 AX.25 G3RUH GFSK telemetry, SSDV image transmission, a digipeater service, and a CW beacon.

Maveric carries spectral imaging experiments and has a 9k6 UHF downlink using Golay framing with GMSK at 437.575 MHz.

Like other Transporter missions, this launch carried a mix of new and returning customers, including those building out or refreshing constellations. Iceye had four radar-imaging satellites on the mission, while Spire had 10 of its Lemur satellites on the launch. Axelspace, a Japanese Earth observation company, flew seven of its GRUS-3 medium-resolution imaging spacecraft on the mission.

These and other companies have relied heavily on SpaceX rideshare missions for low-cost access to space on a regular schedule. However, there are growing concerns within the industry that SpaceX is winding down this program, at least using its workhorse Falcon 9 rocket.

In recent weeks, several partners and customers of those rideshare missions said SpaceX is not accepting Transporter reservations beyond late 2028 or early 2029. They added the missions on the manifest until then are nearly full. That has led companies like Exolaunch and SEOPS, which have arranged launches on Transporter missions, to buy their own Falcon 9 rideshare launches.

SpaceX has not commented on those claims, and its webcast for the Transporter-17 launch did not discuss any changes to the rideshare program.

However, anxiety extends to the availability of the Falcon 9 itself. SpaceX officials said last year they were near the peak of Falcon 9 launch activity and expected the number of launches to start to decline as the company ramps up Starship, its fully reusable heavy-lift vehicle.

14 Million Tracks and Counting: SatNOGS Hits Huge Milestone and Spots Spinning Satellite

Satellite Networked Open Ground Station (SatNOGS) is the biggest open network of satellite ground stations in the world. It is run by volunteers and managed by the Libre Space Foundation. Essentially, it gives anyone a web interface to remotely schedule and control ground stations across the globe. 

One of the most significant aspects is that it relies entirely on regular people building their own setups at home. They use cheap, easy-to-find gear like a Raspberry Pi, a simple USB radio receiver, and basic antennas. Because the software handles all the tracking automatically using orbital data, the stations tune in and catch signals the exact moment a satellite flies overhead.

Big Milestones and Daily Tracking

On May 6, 2026, the network hit a massive milestone when it passed 14 million total observations. It was fitting for the amateur radio community that the record-breaking track happened to be LUSAT, which was Argentina’s very first mini-satellite. The network is incredibly busy right now, bringing in roughly 10,000 observations every single day.

Catching Anomalies in Real Time

SatNOGS does more than just routine tracking. It has turned out to be an amazing tool for spotting when things go wrong in space.

Back in May 2026, everyday users looking at SatNOGS signal charts noticed something weird with India’s Drishti satellite. By analyzing how the signal was fading in and out, independent trackers figured out that the spacecraft was actually tumbling in orbit at 3 degrees per second. This public data gave the world early proof that the satellite was in major trouble, months before official reports finally confirmed it was lost because of a solar storm.

Benefits to AMSAT Community

For AMSAT organizations, SatNOGS offers distinct advantages:

Global Backup: A dense, worldwide network ensures reliable backups if a local station misses a satellite pass.

LEOP Support: It helps teams identify and track new amateur spacecraft during the critical Launch and Early Orbit Phase (LEOP).

Asset Preservation: It ensures that historical assets like LUSAT continue to be actively monitored by enthusiasts worldwide.

Explore the Data

The community makes public observations, waterfall charts, and transmitter details completely open to the public. Real-time tracking data, along with guides on how to build a local ground station, can be found on the official website at https://satnogs.org/.

Securing the Future: Orbit Stabilization of Swift Observatory 

The Swift Rescue Mission (SRM), also referred to as the Swift Boost Mission, is a pioneering satellite-servicing project designed to recover and extend the life of NASA’s Neil Gehrels Swift Observatory. Developed by Katalyst Space Technologies, the mission utilizes a robotic servicing spacecraft named LINK to stabilize the observatory’s orbit and prevent its uncontrolled reentry into Earth’s atmosphere.

Key details of the mission include:
  • The Objective: The Swift Observatory has operated since 2004, but after two decades, atmospheric drag has caused its orbit to decay significantly. Without intervention, there is a high probability that it would reenter the atmosphere in 2026. The mission aims to raise Swift’s orbit to approximately 600 km to preserve its unique capability for detecting gamma-ray bursts.
  • The Spacecraft (LINK): LINK is a 425 kg spacecraft equipped with two 6-meter solar arrays and three xenon-fueled ion thrusters. It features autonomous navigation systems and three robotic arms specifically designed for non-cooperative capture.
  • Innovative Methodology: This mission represents the first attempt to recover an “unprepared” spacecraft — one that was never designed with docking fixtures or grappling points. LINK will autonomously approach Swift, perform a visual inspection, and use its specialized robotic mechanism to secure a structural feature of the observatory without damaging its sensitive instrument.
  • Current Status: LINK was launched on July 3, 2026, from Kwajalein Island aboard a Northrop Grumman Pegasus-XL rocket. Teams have successfully established communications with the spacecraft, which is currently undergoing several weeks of checkout procedures for its propulsion and navigation systems before beginning its rendezvous with Swift.
Once the capture is secured, LINK will spend several months gradually raising Swift’s altitude before detaching and performing its own controlled reentry into the atmosphere.
 
Note: As this mission is currently in its commissioning phase as of July 2026, further technical details regarding the final docking and reboost performance will be released by NASA as the mission progresses

Changes to AMSAT TLE Distribution for July 10, 2026

Two Line Elements or TLEs, often referred to as Keplerian elements or keps in the amateur community, are the inputs to the SGP4 standard mathematical model of spacecraft orbits used by most amateur tracking programs. Weekly updates are completely adequate for most amateur satellites. TLE bulletin files are updated daily in the first hour of the UTC day. New bulletin files will be posted immediately after reliable elements become available for new amateur satellites. More information may be found at https://www.amsat.org/keplerian-elements-resources/.

General Perturbations Data Support

AMSAT is pleased to announce that modern forms of what are called General Perturbations data are being disseminated via modern formats including JSON, XML and KVN at https://newark192.amsat.org/gpdata/current/. The reason this change is being made is that we are running out of 5-digit catalog numbers and the TLE format is not viable for satellites launched after July of this year. See https://celestrak.org/NORAD/documentation/gp-data-formats.php for details.

These data are presently considered in beta test for the next two months while hosted on the test server newark192.amsat.org, and we are very open to community feedback at webmaster at amsat.org. Testers may experience outages and errors while we make improvements. We intend to put this into production on our main web server in July as we expect that satellites launched after this summer will require one of the new formats to accommodate longer object numbers. AMSAT will continue to publish TLE bulletins for satellites launched before July 2026 indefinitely.

Satellite Shorts from All Over

+ AMSAT SA 2026 Space Symposium will be held Saturday, 1 August 2026. The event is conducted online from 10:00 – 14:00 SAST (08:00 – 12:00 UTC) to enable wide attendance without incurring large travel costs. The theme is “The new Amateur Radio World in Space,” exploring practical hands-on aspects of space activities and emerging technologies. Presentations will include outcomes of proposals for new geostationary amateur satellites, including innovative ground-based systems to link LEO and GEO satellite.  Registration is free for members of IARU member societies, while non-members pay a small fee. Visit the AMSAT-SA website for registration details. (ANS thanks AMSAT-SA, for the above information.)

+ NASA’s Moon and Mars Exploration Analog (MMEA) continues to recruit research participants for its upcoming yearlong simulation season. Because the mission’s integrated habitats at the Johnson Space Center in Houston are designed to simulate deep space, participants will operate under the isolated conditions expected during crewed missions to the Moon or Mars. The current recruitment period is active for the year-long mission beginning no earlier than August 2027, during which continuous simulation operations in confined environments could be possible. The mission is HERA/CHAPEA only (HERA habitat spacecraft simulation, CHAPEA habitat base simulation). Volunteers are reminded to meet specific physical and educational requirements and to pass NASA’s physical and psychological assessments, so the mission results can be shared with the Human Research Program to help keep future astronauts safe and mission-ready. (ANS thanks NASA, the Human Research Program and the Artemis mission for the above information.)

+ NSF–DOE Vera C. Rubin Observatory (LSST) continues to reward the global scientific community as it begins its 10-year campaign to create the most comprehensive cinematic record of the Universe in history. Because the observatory’s 3200-megapixel camera—the largest digital camera ever built—has successfully completed system optimization, it is now capturing new, detailed images of the southern sky approximately every 40 seconds. The current Legacy Survey of Space and Time (LSST) runs through the next ten years, during which continuous filming of the dynamic Universe and the production of trillions of measurements should be possible. The survey is Wide-Field/Time-Lapse only (producing 10 terabytes of data and up to 7 million alerts of changes in the night sky every night). Researchers are reminded to utilize automated alert brokers to classify these changes and to ensure timely follow-up of fleeting cosmic events, so this unprecedented resource can be shared by as many scientists and members of the public as possible worldwide.

AMSAT President Drew Glasbrenner, KO4MA, Featured on Ham Radio Workbench Podcast

AMSAT President Drew Glasbrenner, KO4MA, is the featured guest on episode 266 of the Ham Radio Workbench podcast, released June 30, 2026, and available at https://www.hamradioworkbench.com/podcast

In a wide-ranging discussion, Glasbrenner talks with the Workbench crew about AMSAT and amateur radio in space, drawing on the operating and institutional perspective he brings as AMSAT President. The episode’s show notes point listeners toward a number of accessible on-ramps to satellite work, including the WA5VJB “Cheap Yagis” wooden-boom antenna design, Elk log-periodic antennas for satellite use, and AMSAT itself at https://www.amsat.org. The hosts also note that Glasbrenner is interested in hearing from potential payload providers, and that listeners inspired to get more involved can inquire about becoming an AMSAT Ambassador.

Recent AMSAT presentations have offered a preview of the themes Glasbrenner tends to cover. In appearances over the past several months he has described AMSAT as a volunteer, educational organization dating to 1969, highlighted the continued operation of AO-7 more than five decades after launch, and outlined the GOLF-TEE mission — a 3U CubeSat carrying a 30 kHz linear transponder, a 10 GHz high-speed experimental downlink, and improved three-axis attitude control. Listeners looking for an approachable introduction to where AMSAT is headed will find the Workbench episode a good place to start.

MarmotSat: Student-Built Canadian CubeSat Brings Open-Source Amateur Experiments to VHF and 10 Meters

A new student-built CubeSat carrying an unusually varied amateur radio payload is set to reach orbit this month, and its team is actively inviting amateurs around the world to take part. MarmotSat, a 3U CubeSat designed and built in-house by students at the University of Victoria (UVic) Centre for Aerospace Research (CfAR), is manifested on the SpaceX Transporter-17 rideshare mission, targeted to launch from Space Launch Complex 4E at Vandenberg Space Force Base, California, no earlier than July 7, 2026, into a sun-synchronous orbit.

MarmotSat, whose name stands for Mission for Atmospheric Radio Measurements with Open-source Technology Satellite, measures the standard 3U form factor of 340 by 100 by 100 mm. It is British Columbia’s submission to the Canadian Space Agency’s CubeSats Initiative in Canada for STEM (CUBICS) program, and it also features major contributions from volunteers on the UVic Satellite Design (UVSD) engineering team. The mission has two primary objectives: to train Highly Qualified Personnel by giving undergraduate and graduate students hands-on experience designing, building, testing, and operating a spacecraft; and to support the UVic Propagation Laboratory’s research into the structure and composition of the ionosphere. Both the satellite and its ground station in Victoria were designed, assembled, tested, and operated by students, with the sole exception of the commercial CubeSpace attitude determination and control system.

The mission builds directly on the experience of ORCASat, UVic’s earlier 2U CubeSat and British Columbia’s first student-built satellite to reach orbit. ORCASat, which flew under the Canadian CubeSat Project and deorbited in July 2023, gave more than 25 full-time co-op students and over 150 part-time student volunteers direct spacecraft experience, and it flight-qualified the UHF telemetry, tracking and command scheme that MarmotSat reuses.

A rich amateur payload

For amateurs, the interesting part of MarmotSat is its payload, which marks the debut of the Modular CubeSat Radio (MCR), an open-source, GNU Radio-compatible software-defined radio platform developed by the team. Built around a low-power HF SDR derived from the Hermes Lite 2, the MCR for this mission includes the SDR, an onboard computer, a camera, HF and VHF RF front ends, and simple wire antennas: a base-loaded half-wave tape-measure whip for HF and a half-wave tape-measure dipole for VHF.

The amateur payload supports four distinct experiments, and the team stresses that it is available to all properly licensed operators worldwide. Because several functions share the same frequencies, the experiments are mutually exclusive and never run simultaneously. The published frequencies are a VHF digipeater uplink and downlink on 145.875 MHz; a CW telemetry beacon on both 145.875 MHz and 29.410 MHz; and a DVB-S2 digital video beacon and a linear-frequency-modulation sounding downlink, both on 29.410 MHz in the 10-meter amateur satellite allocation. A separate telemetry, tracking and command subsystem operates on 436.125 MHz; that UHF link is kept independent of the amateur payload for reliability and is not intended for general amateur use, though its telemetry may be receivable in the Pacific Northwest.

The four amateur experiments give operators a range of ways to participate:

The CW telemetry beacon transmits spacecraft health data on HF and VHF at 15 words per minute, sending the callsign VA7UVS in plain text followed by encoded telemetry. It can be copied by ear or with digital aids such as CW Skimmer, and requires only a modest 10-meter or VHF antenna and a CW-capable receiver or a low-cost SDR.

The VHF digipeater is a two-way store-and-forward and real-time communication experiment intended to work like the well-known IO-117 (GreenCube) digipeater, but on VHF rather than UHF. The team notes it is designed to be compatible with the hardware and software amateurs already use for GreenCube operation.

The DVB-S2 digital video experiment lets amateurs receive live imagery from the onboard camera as a digital television signal on 10 meters, following the QO-100 wideband operating conventions. It is a deliberately challenging, noise-sensitive experiment; the team recommends it only for operators at quiet rural locations and only on passes above about 35 degrees elevation.

The citizen-science experiment transmits a linear-frequency-modulated waveform, similar to CODAR, on 10 meters. Amateurs can record these transionospheric soundings and submit them to a central repository, contributing to the Propagation Lab’s study of how the ionosphere’s structure may correlate with terrestrial phenomena including earthquakes and human-caused climate change.

In keeping with the mission’s open-source philosophy, the team has released supporting designs and tools to the community, including a 10-meter turnstile antenna suitable for space reception and a GNU Radio flowgraph for decoding the DVB-S2 video, with recording-format and data-submission details for the citizen-science experiment to be published around launch.

Getting involved

The MarmotSat team is inviting experienced stations to help commission the amateur experiments and is offering selected operators early access to the payload; amateurs interested in taking part are asked to contact the team through the UVic Propagation Laboratory with a brief description of their capabilities. Amateur radio information for the mission, including the frequency table, equipment recommendations, and experiment details, is maintained on the Propagation Lab’s satellite page at https://www.propagationlab.ca/satellite/, and general mission information is available at https://www.marmotsat.ca.

As always, amateurs planning to receive MarmotSat should watch for orbital elements and any updates to the experiment schedule after deployment, which the team expects to publish once commissioning is complete in the third quarter of 2026.

OSCARLOCATOR Web Generator Turns Live Elements Into Printable Tracking Sheets

Following last week’s introduction of the browser-based OSCARLOCATOR Web Simulator, a companion tool is now online that closes the loop between the on-screen simulator and the classic paper tracker. The OSCARLOCATOR Web Generator, at https://oscarlocator-pdf.n8hm.radio, produces printable base-map, range-circle, and path-arc sheets — the physical components of the traditional OSCARLOCATOR — as vector PDFs generated entirely in the browser.

Like the simulator, the generator is the work of AMSAT Executive Vice President Paul Stoetzer, N8HM, and produces the same vector output as the OSCARLOCATOR export in his OrbitDeck desktop application. Nothing is uploaded to a server: the tool fetches only current AMSAT GP orbital elements and, if the operator asks, their location. It runs offline once loaded.

The OSCARLOCATOR Web Generator, showing the station, satellite, and sheet-option controls on the left and a live preview of the base map for AO-73 on the right, along with the orbital readout and PDF download and print controls

To build a set of sheets, the operator sets a station by Maidenhead grid square, by latitude and longitude, or via browser geolocation, then selects a satellite from a list populated automatically from AMSAT’s GP element data. The map projection can be a polar azimuthal-equidistant sheet — chosen automatically for the northern or southern hemisphere, or forced to North or South — or a QTH-centered azimuthal map. The output can be produced as a two-sheet set, pairing a base map with the range circle drawn at the operator’s station plus a separate path-arc transparency, and an option keeps the overlay transparencies free of text so all the how-to-use instructions live on the base map. An advanced panel allows manual entry of orbital elements — inclination, mean motion, eccentricity, argument of perigee, and RAAN — for cases where the operator wants to plot a specific orbit by hand, and provides an optional CORS-proxy override for fetching the AMSAT bulletin data.

Coastlines are drawn from Natural Earth 110m data. The sheets must be printed at 100% / actual size so that the base map and the transparency overlays register correctly when stacked. The result is a genuine, working paper tracker keyed to current elements — a satisfying bridge between the pre-computer era of satellite operating and modern on-demand data.

The OSCARLOCATOR Web Generator is available now at https://oscarlocator-pdf.n8hm.radio, and serves as a companion to the OSCARLOCATOR Simulator at https://oscarlocator.n8hm.radio.

Recent IARU Amateur Satellite Frequency Coordination Activity

Every amateur satellite that expects to transmit in the amateur-satellite service bands is asked to obtain a frequency coordination from the International Amateur Radio Union (IARU) before launch. The IARU Satellite Frequency Coordination Panel reviews each request, checks the proposed frequencies against existing band plans and other coordinated missions, and — where the mission fits the definition of the amateur-satellite service and names a licensed amateur as the responsible operator — recommends frequencies intended to minimize mutual interference. The running status of applications is maintained on the AMSAT-UK-hosted status pages at https://iaru.amsat-uk.org/index.php, and it is worth a periodic look for operators who like to know what may be arriving on the bands.

Over roughly the past month the panel’s public status list has continued to turn over, with the two most recently updated entries both coming from long-running university programs in Europe.

The most recent update, dated June 23, 2026, is UPMSat-3, developed by the Instituto Universitario de Microgravedad “Ignacio Da Riva” (IDR) of the Universidad Politécnica de Madrid (UPM). UPMSat-3 continues a program that reaches back to UPMSat-1 in 1995 and UPMSat-2 in 2020. The new spacecraft is a roughly 22-kilogram microsatellite — smaller than its predecessors but a substantial step up in capability — whose primary science mission is imaging of the cosmic microwave background, alongside a suite of low-cost in-orbit technology demonstrations for Spanish companies and research centers and continued work on attitude determination and control algorithms. UPMSat-3 has been selected to fly on the Isar Aerospace Spectrum launcher from Andøya, Norway, and the program continues to build hands-on engineering experience for students in UPM’s Master’s Degree in Space Systems (MUSE).

The panel’s prior update, dated June 4, 2026, is FramSat-1.5, a 3U CubeSat from the Norwegian University of Science and Technology (NTNU) and the student organization Orbit NTNU. FramSat is a scaled evolution of Orbit NTNU’s earlier SelfieSat, and the FramSat effort is closely tied to the ambition of launching “the first satellite from Norwegian soil” from the new spaceport at Andøya. FramSat carries a UHF amateur downlink — SatNOGS lists a 435.141 MHz 9k6 FSK (AX.25/G3RUH) transmitter marked IARU coordinated — supporting telemetry and an experimental sun-sensor payload built by students.

Both missions are representative of the bulk of IARU coordination traffic: student- and university-led educational spacecraft, most in low Earth orbit, that give the next generation of engineers direct experience with spacecraft communications while adding new signals for the amateur community to hunt. Developers planning a mission are reminded that coordination should be requested as early in the design process as possible, while frequencies can still be changed in response to the panel’s recommendations.

Application forms and contact information are available at https://www.iaru.org/reference/satellites/, and the coordination status list is at https://iaru.amsat-uk.org/index.php.

Amateur Radio Payloads Aboard SpaceX Transporter-17

SpaceX is targeting Tuesday, July 7, 2026, for the launch of its Transporter-17 dedicated rideshare mission, with a 95-minute window opening at 07:10 UTC (12:10 a.m. PDT) from Space Launch Complex 4E at Vandenberg Space Force Base, California. A backup opportunity is available on July 8 at the same time. The Falcon 9 will carry a large collection of small satellites — deployment provider Exolaunch alone has manifested 49 spacecraft on the flight — into a sun-synchronous orbit, and among them are several carrying amateur radio payloads. As with all Transporter missions, deployments will be spaced out over a period of time after launch rather than occurring all at once, and it may be days or weeks before individual satellites are commissioned and heard.

As of this writing the full manifest is still being cataloged by the amateur community, and operators coordinating reception through the Libre Space Foundation’s SatNOGS network are working to add the new spacecraft and their transmitters to the SatNOGS database. Amateurs are encouraged to help by submitting satellite and transmitter suggestions. The confirmed amateur payloads with IARU-coordinated frequencies are summarized below; more may be identified as the manifest firms up.

MarmotSat, the 3U CubeSat built by students at the University of Victoria Centre for Aerospace Research, is the headline amateur payload on the flight and is the subject of a separate feature in this issue. It carries the debut of the open-source Modular CubeSat Radio and supports four amateur experiments: a VHF digipeater and CW telemetry beacon on 145.875 MHz, a CW telemetry beacon and a DVB-S2 digital video beacon on 29.410 MHz, and a linear-frequency-modulation ionospheric-sounding downlink on 10 meters for amateur citizen scientists. Its IARU-coordinated downlinks are 29.410 MHz, 145.875 MHz, and 436.125 MHz (TT&C). The team hopes MarmotSat will become Canada’s first official OSCAR-designated satellite. See the full article elsewhere in this bulletin for details and for how to take part in commissioning.

Maveric

Maveric is a 3U CubeSat from the University of Southern California’s Space Engineering Research Center, with Anthony Planinac, K6FCF, as the responsible operator. The satellite carries two identical commercially available multispectral imagers, each of which will photograph an LCD screen positioned in front of the camera with the Earth and sky as a backdrop. The mission’s goals are a mix of science and technology development, including magnetic-field measurements and the testing of new algorithms for real-time onboard processing of optical imagery.

For amateurs, Maveric uses a 9,600 bps UHF downlink employing GMSK modulation with Golay framing. The IARU has coordinated a downlink on 437.575 MHz. The satellite is bound for an approximately 590 km polar orbit. Reception reports and telemetry decodes from the amateur community are, as always, valuable to the mission team during commissioning.

Other payloads of note

Also aboard Transporter-17 is LabSat IoT, a 34-cm CubeSat developed by the Faculty of Engineering at the University of Palermo in Argentina, together with COPITEC and FUNDETEC. LabSat IoT is a technology-demonstration platform for satellite Internet-of-Things and cellular (NTN) connectivity to remote areas, using in-flight-reconfigurable software-defined radios. Its experiments operate in IoT and mobile-satellite bands rather than the amateur-satellite service, so while it is a noteworthy student-built spacecraft on the same flight, it is not an amateur radio mission and does not carry an IARU-coordinated amateur payload.

The mission also includes numerous commercial and government smallsats — among them Firesat-1, -2, and -3, and a wide range of Earth-observation and technology-demonstration spacecraft from more than twenty countries — that do not use amateur frequencies.

Operators wishing to receive the amateur payloads should watch for orbital elements to be published after deployment and match them to each spacecraft using the beacon signals. Frequency and status details for coordinated satellites can be confirmed on the IARU coordination status pages at https://iaru.amsat-uk.org, and reception can be coordinated through the SatNOGS network. ANS will report on successful deployments and the opening of the new satellites’ amateur payloads as information becomes available.

AMSAT at Moon Day, Dallas – Saturday, July 18, 2026

AMSAT Ambassador Tom Schuessler, N5HYP, writes:

“Hello AMSATters in and around the Dallas/Fort Worth area.

“We are coming up quickly toward the annual STEM event held by the Frontiers of Flight Museum at Dallas Love Field called ‘Moon Day.’ This year it will be Saturday, July 18th. Hours are from 10 AM to 4 PM. Always held around the time of the Apollo 11 moon landing, it is a fun public event showcasing astronomy, space science and technology, suitable for young and old alike. Last year it drew almost 1500 visitors. See https://flightmuseum.com/events/moonday/ for more information.

“I have been representing AMSAT and amateur radio satellites at Moon Day for many years now. We have an exhibit table right next to the Dallas Amateur Radio Club where we show off the AMSAT CubeSat Simulator, the Fox CubeSat engineering model, talk about orbits and footprints and this year, hope to have materials to hand out for kids from the AMSAT youth initiative, BuzzSat. Of course we feature the ISS as a great example of amateur radio in space. The CubeSat Simulator gives the ability to have a ‘Get your picture taken by a satellite’ photobooth experience. We also try to offer several voice satellite passes out in the parking lot to show off amateur radio space communications.

“Besides all the regular exhibits, attendees can attend various seminars and hear talks by astronauts.

“The museum has wonderful exhibits, including the Apollo 7 command module. This year there is a new exhibit on the Hindenburg which looks very interesting.”

Changes to AMSAT TLE Distribution for July 3, 2026

Two Line Elements or TLEs, often referred to as Keplerian elements or keps in the amateur community, are the inputs to the SGP4 standard mathematical model of spacecraft orbits used by most amateur tracking programs. Weekly updates are completely adequate for most amateur satellites. TLE bulletin files are updated daily in the first hour of the UTC day. New bulletin files will be posted immediately after reliable elements become available for new amateur satellites. More information may be found at https://www.amsat.org/keplerian-elements-resources/.

There are no changes to this week’s TLE distribution.

General Perturbations Data Support

AMSAT is pleased to announce that modern forms of what are called General Perturbations data are being disseminated via modern formats including JSON, XML and KVN at https://newark192.amsat.org/gpdata/current/. The reason this change is being made is that we are running out of 5-digit catalog numbers and the TLE format is not viable for satellites launched after July of this year. See https://celestrak.org/NORAD/documentation/gp-data-formats.php for details.

These data are presently considered in beta test for the next two months while hosted on the test server newark192.amsat.org, and we are very open to community feedback at webmaster at amsat.org. Testers may experience outages and errors while we make improvements. We intend to put this into production on our main web server in July as we expect that satellites launched after this summer will require one of the new formats to accommodate longer object numbers. AMSAT will continue to publish TLE bulletins for satellites launched before July 2026 indefinitely.

Satellite Shorts from All Over

+ AMSAT Field Day 2026 ran June 27–28 alongside the ARRL event. Operators enjoyed access to more than 10 transponders/repeaters. FM voice limited to one QSO per bird (including ISS); linear birds (AO-7, RS-44, etc.) supported multiple contacts. The ISS repeater was noted as one of the busiest “stations” during Field Day. Many operators reported successful satellite QSOs. Logs due to KK5DO by July 28. See https://www.amsat.org/field-day/ for submission details (ANS thanks AMSAT for the information)

+ Fuji-OSCAR 29 (FO-29 / JAS-2) continues to reward operators during its extended full-sunlight season. Because the Japanese satellite’s onboard batteries failed years ago, its V/U inverting linear transponder operates only when the solar panels are illuminated. The current full-sunlight period runs through mid-November 2026, during which continuous transponder operation on illuminated passes should be possible. The transponder is SSB/CW only (uplink 145.900–146.000 MHz LSB, downlink 435.800–435.900 MHz USB). Operators are reminded to keep uplink power to the minimum needed and to ensure the downlink signal does not exceed the CW beacon level, so the limited resource can be shared by as many stations as possible worldwide. (ANS thanks AMSAT and JARL for the above information)

+ PARUS-T2 and RIDU-Sat 1 launched June 23 at 2125 UTC; both appear dead or non-functional per latest reports. PARUS-T2 carried APRS on 145.825 MHz. Other active/testing birds include HADES-SA (SO-127) with SSDV/CODEC2/FSK, Lilium-4 (APRS + V/U repeater), and RS83S (Lobachevsky) sending images on 436.320 MHz with experimental X-band. Upcoming: UNNE-1B (HADES-E2) targeted for October 2026 with FM voice, FSK, APRS, and CODEC2 capabilities. (ANS thanks AMSAT Upcoming Satellites for the information)

+ NASA astronauts Chris Williams (EV1, red stripes) and Jessica Meir (EV2) conducted a ~6.5–7 hour spacewalk on June 30 starting ~8:35 a.m. EDT / 1235 UTC. They successfully replaced a malfunctioning wrist joint on the Canadarm2 robotic arm (the joint had shown elevated motor current on May 27). This was Williams’ second and Meir’s fifth spacewalk. Live coverage was widely available on NASA+, YouTube, and other platforms. Preview conference held June 25. ARISS systems were powered down around the EVA and restored July 1.

Classic OSCARLOCATOR Returns as Browser-Based Tracking Simulator

A new browser-based recreation of the classic OSCARLOCATOR satellite tracking aid is now online and free for all amateurs to use at: https://oscarlocator.n8hm.radio/

The OSCARLOCATOR Web Simulator is the work of AMSAT Executive Vice President Paul Stoetzer, N8HM, and is modeled on his OrbitDeck desktop application. It runs entirely in a web browser on desktop and mobile devices, with no login, installation, or plug-ins required.

For amateurs who came to satellite operating after the era of paper tracking devices, the original OSCARLOCATOR was a circular, azimuthal-equidistant map of one hemisphere paired with a rotating clear overlay. By aligning the overlay to a satellite’s equator crossing, an operator could determine where the spacecraft would appear in the sky and when it would be in range — all without a computer. N8HM’s web version preserves that look and method while adding the convenience of live, on-demand computation.

The OSCARLOCATOR Web Simulator, showing the polar azimuthal-equidistant map, ground track, range circle, footprint, and the station and sweep controls.

The simulator renders the familiar polar azimuthal-equidistant map as well as a QTH-centered version, automatically choosing the North or South polar sheet for the operator’s location. It draws the satellite’s ground track with 10-minute time marks, plots a range circle over the operator’s station, and shows the spacecraft’s instantaneous footprint. A live readout reports the sub-satellite point, azimuth and elevation from the station, slant range, and whether the satellite is above the horizon.

A close-up of the polar map: the blue ground track with 10-minute marks, the green satellite marker and dashed footprint over the amber range circle and station, and the live data readout.

Operators can drive the display live in real time, pin an equator crossing to a chosen longitude and step forward minute by minute, or jump directly to the next visible pass over their location. A QTH-centered view places the operator’s station at the center of the map with azimuth bearings and great-circle distance rings — the same geometry used by a physical OSCARLOCATOR card.

The QTH-centered azimuthal-equidistant view, with the station at the center cross, compass bearings around the rim, distance rings in kilometers, and a satellite pass crossing overhead.

A “Next Passes” panel lists the next ten visible passes over the operator’s QTH, with acquisition-of-signal, peak, and loss-of-signal times, pass duration, and maximum elevation and bearing. A single click seeds any listed pass onto the map. A separate reference-orbit table gives equator-crossing times and longitudes suitable for setting a physical OSCARLOCATOR.

The Next Passes panel lists upcoming passes with AOS, peak, LOS, duration, and maximum elevation — each with a one-click Seed button.

The satellite picker is fed from current AMSAT GP (General Perturbations) orbital element data, with a bundled offline snapshot so the tool remains usable if live data cannot be retrieved. The station can be set by Maidenhead grid square, by latitude and longitude, or automatically through the browser’s geolocation. During live tracking the display follows the satellite across the equator, switching between the North and South polar sheets as appropriate.

Position calculations use a from-scratch SGP4/SDP4 propagator validated against the published Vallado reference vectors, with correct deep-space handling so that high-altitude and geosynchronous satellites such as QO-100 are displayed at their true sub-satellite points.

The OSCARLOCATOR Web Simulator is free to use and available online at https://oscarlocator.n8hm.radio. Amateurs new to satellite work may find its visual, hands-on approach a useful way to build intuition for how amateur satellites move and when they can be worked from a given location.

Katalyst Launches Spacecraft to Rescue NASA’s Swift Observatory

Katalyst Space Technologies is preparing to launch its LINK servicing spacecraft aboard Northrop Grumman’s Pegasus XL rocket no earlier than June 30. The mission will attempt to rendezvous with NASA’s Swift Observatory and raise its orbit, potentially extending the life of the 22-year-old space telescope. The launch is expected to mark one of the first operational attempts to capture and service an unprepared satellite already in orbit.

Swift was launched in 2004 to study gamma-ray bursts, among the most energetic events in the universe. Although the observatory remains scientifically productive, it was built without propulsion capable of maintaining its orbit. Atmospheric drag has gradually reduced Swift’s altitude over the past two decades, and increased solar activity accelerated that decay. NASA determined the spacecraft was at risk of descending too low for safe servicing operations later this year.

To preserve the observatory, NASA selected Katalyst Space Technologies in 2025 to develop a rapid-response rescue mission. The company designed and built the LINK servicing spacecraft in less than one year, an unusually short schedule for a mission of its complexity. LINK carries electric propulsion and a robotic capture system designed to attach itself to satellites that were never intended to be serviced in orbit.

Following launch, LINK will enter orbit and begin initial spacecraft checkout and commissioning activities. In the coming weeks, the spacecraft is expected to perform a series of orbital maneuvers to match Swift’s orbit before attempting a close approach. Once in position, three robotic arms will be used to capture the observatory and establish a secure mechanical connection.

The mission is expected to mark the final flight of Northrop Grumman’s Pegasus XL launch vehicle. First flown in 1990, Pegasus pioneered commercial air-launched access to space and completed dozens of missions during its 36-year career. The launch will utilize the last Pegasus XL rocket remaining in inventory and will be conducted from the L-1011 carrier aircraft Stargazer, believed to be the last operational Lockheed TriStar aircraft still flying.

If successful, the Swift rescue mission could establish a new model for extending the lives of aging spacecraft. Beyond preserving a valuable scientific observatory, the mission will demonstrate technologies that may one day allow commercial operators and government agencies to service satellites rather than replacing them. The mission is being closely watched as a potential milestone in the growing field of commercial on-orbit satellite servicing.

Rocket Lab Launches Spacecraft for Space Force Orbital Exercise

Rocket Lab successfully launched a spacecraft for the U.S. Space Force’s Victus Haze mission on June 19, lifting off aboard an Electron rocket from the company’s Launch Complex 1 in Mahia, New Zealand. The spacecraft, known as Victus Haze Puma, was placed into a sun-synchronous orbit and will participate in a military demonstration designed to test rapid response capabilities and on-orbit spacecraft operations.

Victus Haze is the fourth mission conducted under the Space Force’s Tactically Responsive Space (TacRS) program. The initiative seeks to demonstrate how commercial launch providers and spacecraft manufacturers can rapidly deploy satellites when needed. Unlike earlier demonstrations that focused primarily on launch readiness, Victus Haze expands the concept by evaluating spacecraft operations after reaching orbit.

Following launch, the Puma spacecraft entered a commissioning phase before beginning rendezvous and proximity operations with another spacecraft already in orbit. The mission will pair Rocket Lab’s vehicle with True Anomaly’s Jackal-004 spacecraft, which launched in May aboard a SpaceX Falcon 9 rideshare mission. During the exercise, the spacecraft will perform a variety of maneuvers intended to demonstrate space domain awareness and the ability to characterize nearby objects in orbit.

The mission also showcased the responsiveness of Rocket Lab’s launch system. After receiving a formal launch order from the Space Force, the company launched the Electron rocket within 16 hours and 42 minutes, surpassing the program’s 24-hour launch requirement. Rocket Lab reported that mission planners calculated a final trajectory to a previously undisclosed orbit, updated flight software, and coordinated ground station support within only a few hours of receiving the order.

Victus Haze builds on lessons learned from the Victus Nox mission conducted in 2023. That earlier demonstration proved that commercial providers could rapidly launch a satellite following a short-notice tasking. Victus Haze extends the concept by demonstrating that responsive space operations can continue after launch, including the ability to maneuver spacecraft, inspect nearby objects, and gather information about activities occurring in orbit.

Space Force officials view these capabilities as increasingly important as Earth orbit becomes more crowded and strategically significant. Future military and civil missions may require the rapid deployment of spacecraft to replace damaged satellites, investigate unusual activity, or provide additional sensing capabilities. Through partnerships with commercial companies such as Rocket Lab and True Anomaly, the Victus Haze mission aims to demonstrate that these capabilities can be delivered on operational timelines measured in hours and days rather than months.

Researchers Propose StormWall System to Reduce Solar Storm Impacts

Scientists have proposed a new concept called StormWall that could one day help protect satellites, communications systems, and power infrastructure from severe solar storms. The idea, described in a recent paper published in the journal Space Weather, would use a fleet of spacecraft to temporarily strengthen Earth’s natural magnetic defenses when dangerous space weather is approaching.

Earth is normally protected by its magnetosphere, a magnetic field that deflects much of the charged particle radiation emitted by the Sun. During powerful solar eruptions, however, interactions between the solar wind and Earth’s magnetic field can allow large amounts of energy to enter near-Earth space. These events can disrupt satellite operations, radio communications, navigation systems, and electric power grids.

The proposed StormWall system would deploy six spacecraft in geosynchronous orbit. Each spacecraft would carry stores of material such as barium, lithium, sodium, or calcium. When a major solar storm is detected, the spacecraft would release the material into space, where sunlight would ionize it and create an artificial cloud of plasma.

An ESA illustration depicts the interaction between charged particles from the Sun and Earth’s magnetosphere. [Credit: ESA]
Researchers believe this plasma cloud could increase the mass density along the sunward boundary of the magnetosphere. Computer simulations suggest that the added material would reduce the efficiency of magnetic reconnection, the process that allows solar storm energy to penetrate Earth’s magnetic shield. By slowing this process, StormWall could lessen the severity of geomagnetic storms reaching Earth.

To evaluate the concept, the research team simulated the effects of the May 2024 “Mother’s Day” geomagnetic storm. Their results indicated that StormWall would not eliminate the storm entirely but could reduce key measures of storm intensity by more than 50 percent. The researchers also concluded that the amount of material required and the launch capabilities needed for the system are within the reach of current technology.

The concept remains a theoretical proposal and no StormWall mission has been approved or funded. Nevertheless, the study represents an unusual approach to space weather mitigation, shifting the focus from forecasting solar storms to actively reducing their impact. As satellite constellations and other orbital infrastructure continue to expand, researchers suggest that large-scale protective systems may become increasingly attractive in the future.

+ Bird Chaser Bingo Summer 2026 has its first Full Eclipse winner, with Mark KO6MBI of Sacramento, California, becoming the first participant to complete every square on the event’s satellite operating challenge card. Event organizer Sean Borgerson, KK7OVF, noted that KO6MBI is relatively new to amateur radio satellites and encouraged operators to listen for him on the air. Bird Chaser Bingo is a summer-long activity that challenges operators to complete satellite-themed operating objectives involving contacts, grids, satellites, and special operating situations. Participants can earn recognition for completing traditional bingo patterns or attempt the more difficult Full Eclipse by finishing the entire card. The event runs through August 31, 2026, with completed cards due by September 15, 2026. Additional information and downloadable bingo cards are available at https://borgersons.com/.

+ SpaceX launched its new Starfall reentry capsule on June 23 aboard a Falcon 9 rocket from Cape Canaveral Space Force Station in Florida. The spacecraft is designed to carry cargo and research payloads to low Earth orbit and safely return them to Earth for recovery. Starfall can accommodate up to 1,000 kilograms (2,200 pounds) of payload and is intended to support applications such as orbital manufacturing and scientific research. The capsule uses a carbon-fiber heat shield, nitrogen gas attitude-control system, and parachute-assisted splashdown recovery. During the June 23 flight demonstration, SpaceX targeted a recovery area in the Pacific Ocean approximately 1,300 kilometers (700 nautical miles) off the U.S. West Coast. The mission marked Starfall’s first flight test, with at least one additional demonstration mission planned. (ANS thanks Space.com for the above information)

+ Scale RF has launched a Crowd Supply campaign for its QuadRF 4×4 MIMO software-defined radio development kit. The QuadRF operates from 4.9 to 6.0 GHz in the C-band and provides four full-duplex transmit and receive channels with up to 1 watt of output power per antenna. The kit includes four dual-polarization antennas, an integrated Raspberry Pi 5, and open-source software for beamforming and phased-array experimentation. Scale RF says the design is intended as the building block for larger phased-array systems, including its planned MoonRF architecture for Earth-Moon-Earth communication and radio astronomy. The complete QuadRF kit is priced at $499 during the Crowd Supply campaign, with initial deliveries expected this fall. Additional information is available on the Crowd Supply campaign page at https://www.crowdsupply.com/scale-rf/quadrf#. (ANS thanks Scale RF for the above information)

+ Researchers at NASA’s Glenn Research Center in Cleveland, Ohio, are testing a regenerative fuel cell system that could provide long-duration energy storage for future Artemis missions to the Moon. The system generates electricity by combining hydrogen and oxygen into water, then recharges by splitting the water back into its original gases for repeated use. The technology could provide a lighter alternative to batteries while storing enough energy to power habitats, rovers, and other lunar systems through the Moon’s two-week-long nights. Engineers recently began testing the complete integrated system, including storage of the hydrogen and oxygen produced during recharge. Data gathered during the test campaign will help prepare the technology for future environmental testing under simulated lunar conditions. If successful, regenerative fuel cells could become an important part of the infrastructure needed to support sustained human exploration of the Moon. (ANS thanks NASA for the above information)
