ARISS Announces NASA Astronaut Tony England WØORE as Speaker for 40th Anniversary Celebration

Amateur Radio on the International Space Station (ARISS) has announced NASA astronaut Tony England WØORE as the latest addition to the esteemed lineup for the “40th Anniversary Conference: Celebrating the Positive Impact of Amateur Radio on Human Spaceflight” event at Kennedy Space Center, set to occur from February 22 to 24, 2024. Tony England will be the third astronaut speaker at the event, in addition to Richard Garriott, W5KQW, and Bill McArthur, KC5ACR.

Tony England, the second astronaut to make ham radio contacts from space and the first to engage in Slow-Scan Television (SSTV) transmissions from orbit, brings a wealth of experience to the event. Selected as a scientist-astronaut by NASA in August 1967 at the age of 25, he holds the distinction of being the youngest candidate selected up to that time. England completed rigorous academic and flight training, earning his wings with distinguished honors in April 1969.

His contributions to space missions include serving as a support crewman for Apollo 13 and 16 flights. Notably, England played a crucial role during the Apollo 16 mission as the Extra-Vehicular Activity (EVA) Capcom, providing instructions to astronauts exploring the lunar surface. His expertise also extended to the development and communication of instructions for constructing lithium hydroxide canisters on Apollo 13.

In the summer of 1985, England was a part of the STS-51-F mission, which carried a seven-man crew and Spacelab-2. This mission marked the first pallet-only Spacelab mission and the debut of the Spacelab Instrument Pointing System (IPS). England’s responsibilities included activating and operating Spacelab systems, operating the IPS and the Remote Manipulator System, assisting with experiment operations, and being prepared for a contingency Extra-Vehicular Activity if needed. The mission successfully completed 126 orbits of the Earth.

Richard Garriott W5KQW, a second-generation space traveler, ARISS veteran, and entrepreneur, has been announced as the keynote conference speaker. The 40th Anniversary Celebration event will also feature other distinguished speakers, including Bill McArthur, KC5ACR, a NASA Astronaut with experience on the Shuttle, Mir, and the International Space Station (ISS), and Mike Kincaid, NASA Associate Administrator for the Office of STEM (Science, Technology, Engineering, and Mathematics) Engagement.

The 40th Anniversary Conference is scheduled to occur at the Center for Space Education, located next to the NASA Kennedy Space Center Visitor’s Center in Florida. This event is not only a reflection on past achievements but also a platform to showcase the exciting potential of amateur radio in future human spaceflight endeavors. The discussions will encompass potential operations on commercial space stations, lunar exploration, and even ventures toward Mars. The celebration is poised to offer a retrospective of notable achievements and delve into the evolving role of amateur radio in shaping the trajectory of human space exploration. More details can be found on the ARISS website at https://www.ariss.org/overview.html.

Vulcan Centaur Triumphs in Maiden Voyage, Peregrine Lander Faces Lunar Setback

Vulcan Centaur, a new heavy-lift booster developed by United Launch Alliance (ULA), successfully completed its inaugural flight. However, the mission took a bittersweet turn as the Peregrine lander, set to be the first American spacecraft to touch down on the lunar surface since 1972, faced significant challenges shortly after separation from the Centaur upper stage.

United Launch Alliance (ULA), known for its 100% mission success rate with the Atlas V and Delta IV rockets since 2006, faced a changing commercial launch landscape by the early 2010s. SpaceX’s Falcon 9 was offering cheaper alternatives, prompting ULA to develop a more cost-effective and agile solution. The result was the Vulcan Centaur, a combination of a new first stage and an evolved Centaur III second stage.

Originally planned for launch in 2019, the Vulcan program encountered delays, primarily due to the slower-than-expected development of the BE-4 engines by Blue Origin. Despite setbacks and an explosion during Centaur upper stage testing in March 2023, the January 8th launch marked a significant achievement for ULA. Powered by liquid methane and liquid oxygen (methalox), the Vulcan Centaur demonstrated successful flight, a milestone for American orbital rockets using this propellant combination.

ULA’s CEO Tory Bruno expressed satisfaction with the launch, labeling it one of the smoothest in his career. The successful flight positions ULA to compete more effectively in the evolving space launch market.

While the Vulcan Centaur celebrated success, the fate of the Peregrine lander took a dramatic turn. Developed by Astrobotic Technology, Peregrine had ambitious plans, including bringing memorials, time capsules, scientific instruments, the Iris rover, and small robots to the lunar surface.

Initial reports suggested a promising start when Peregrine separated from the Centaur and established communications with ground control. However, soon after enabling its propulsion systems, the lander faced difficulties maintaining its orientation, leading to a rapid depletion of its batteries. Astrobotic attempted to stabilize the craft, but it was confirmed that a leak was destabilizing Peregrine and draining essential propellants needed for a lunar landing.

Astrobotic ruled out any possibility of a lunar landing, and as of the latest update, the team faces the challenge of navigating Peregrine as close to the Moon as possible before its propellant runs out. With communication uncertain, the fate of the lander remains uncertain.

January 8th showcased both success and setbacks in space exploration. The Vulcan Centaur’s triumphant launch demonstrated progress in rocket technology, while the Peregrine’s struggles highlighted the inherent difficulties of space missions. As technology advances, the moon remains an enticing destination, with the upcoming Nova-C lander’s launch in February offering renewed hope for successful lunar exploration. The events of this day remind us that despite the challenges, the pursuit of space exploration continues unabated.

W2RS Memorial AMSAT CW Activity Day to be Held January 1st

In March 2022, the AMSAT community lost one of our pioneers when Ray Soifer, W2RS, became a silent key. In addition to his numerous contributions to AMSAT and the worldwide amateur satellite community, Ray was also the long time organizer of AMSAT’s CW Activity Day – previously AMSAT Straight Key Night – held in conjunction with the ARRL’s event on New Year’s Day. In recognition of Ray’s long time service to AMSAT and his keen interest in CW operating via satellite, AMSAT’s CW Activity Day is now known as the W2RS Memorial AMSAT CW Activity Day.

The rules are simple – operate CW through any amateur satellite between 0000 UTC and 2359 UTC on January 1, 2024. Straight keys and bugs are encouraged, but not required. Logs are not required, but operators are encouraged to submit a report of their activity to the AMSAT-BB. Photos and video clips of activity are also encouraged – post them on X or other social media networks and tag @AMSAT or #amsat.

Remember to use the minimum power required for communication as constant carrier modes, including CW, can disrupt transponder operation for other users.

Student-Led ARISS Contact a Success

A student-led contact with astronauts through the Amateur Radio on the International Space Station (ARISS) program was a great success that earned significant media attention. On Monday, December 11, students at Harbor Creek High School in Harborcreek, Pennsylvania, used amateur radio to talk with Astronaut Andreas Mogensen, KG5GCZ.

The students are part of the Advanced Technologies Group, KC3SGV, an after-school club at Harbor Creek. Fifteen of the students are licensed radio amateurs. As ARRL News reported last week, their faculty advisor, Assistant Principal Drew Mortensen, AC3DS, is a graduate of the ARRL Teachers Institute on Wireless Technology. He utilized what he learned in the program and brought it back to the school. The ARISS contact is just one of the many successes the program has had.

ARRL Education and Learning Manager Steve Goodgame, K5ATA, was on hand for the contact, and he was impressed by the skills demonstrated by the students.

Goodgame recalled, “From antenna assembly and installation to the actual control operator function of the radio during the contact itself, students were at the helm. Every student who asked a question of Commander Mogensen was a licensed amateur radio operator. When I asked what they had planned next, the response was, ‘Well, the logical step would be to build and get a CubeSat launched.’ This is exactly the type of program we hope to help create as an outcome of the Teachers Institute,” said Goodgame.

Local, regional, and national media took note of the students’ success. Local television newscasts (see Amateur Radio in the News below) featured the event, and NBC Journalist Harry Smith and a crew from NBC’s TODAY were at the event to tell the story about the young hams.

This type of exposure for amateur radio is key to growing the hobby, according to ARRL Public Relations and Outreach Manager Sierra Harrop, W5DX. “The passion of these teenage operators led to this success story. Who doesn’t love the story of young minds doing extraordinary things in STEM through amateur radio?” she exclaimed. ARRL Director of Development Kevin Beal, K8EAL, mentioned that the media coverage demonstrates the impact that the donors who have funded the Teachers Institute have on the future of amateur radio. Beal said, “The reach goes far beyond the one-week training institute and ripples out farther than we can see.”

The ARRL Teachers Institute on Wireless Technology is funded by the ARRL Education and Technology Fund. If you are interested in supporting STEM education through the Teachers Institute on Wireless Technology, visit https://www.arrl.org/GiveToSTEM.

HADES-D Designated SO-121, Active For General Use

HADES-D satellite has been commissioned. After a trial period in which its behavior has been tested at the radioelectric, systems, and energy performance levels, the FM repeater is left active for general use.

At the request of AMSAT-EA, AMSAT has designated HADES-D as Spain-OSCAR 121 (SO-121). AMSAT congratulates AMSAT-EA, thanks them for their contribution to the amateur satellite community, and wishes them continued success on this and future projects.

The repeater works with FM/FSK (MSK144 has been tested too) with an uplink frequency of 145,875 MHz and a downlink frequency of 436,663.5 MHz (a bit lower than the 436.666 MHz expected). We have been able to verify that the modulation is more appropriate by narrowing the bandwidth, so it is recommended to use NFM in those devices allowing it.

AMSAT-EA is drafting a use and operation manual, which will be published shortly and which will indicate in detail some of the characteristics of the satellite and its working modes. Although it is not definitive, Amsat-EA is considering some special operating options such as reserving a day of the week exclusively for digital communications following the example we know with the AO-92.

Finally, please, remember that, as far as we know, HADES-D is the first satellite with FM repeater service mounted on a pocketqube platform. This standard is the smallest in terms of normalized satellite sizes. HADES-D size is 8x5x5 cm. Its panel surface and battery size are much smaller than the rest of the satellite repeaters in use, so HADES-D is not comparable to most of them either in radiated power or signal strength. HADES-D should be considered a QRP satellite.

ClarkSat-1 Deployed from ISS

ClarkSat-1 was one of two cubesats deployed from the International Space Station (ISS) via the Japanese “Kibo” module on Monday, December 18. Also known by the name “AMBITOUS,” and by the callsign JS1YLT, the satellite was described as follows in frequency coordination applications:

ClarkSat-1 is a 1U size satellite, and about 22 students of Clark Memorial International High School having amateur radio qualification or intending to obtain it will be engaged in the development of the satellite, and operate it by using the amateur radio band.

+ Optical Camera Mission To take pictures of the Earth and downlink them in 430 MHz band (GMSK, 4,800 bps). The pictures are to be received at control station and general amateur stations are also expected to receive them and report to us as the downlink schedule will be published on our website and social media.

+ Digi-talker Mission 40 to 120 seconds long Digi-talker signal (Voice or SSTV pictures in Robot 36 format recorded before launch) including the call sign and school name will be transmitted from the satellite and be expected that the general amateur stations will receive the signal and report back to us.

High school students with amateur radio license will be engaged in the development of the satellite, and high school students will operate the satellite. These activities will improve the amateur radio and satellite communication skills of the students. The project will also serve as a model case for the development of amateur satellites by the younger generation, and stimulate the interest of the younger generation in amateur radio and satellite communications. The satellite information, such as orbital position and operation time, will be actively disseminated to the world through the website and social media, so that radio amateurs all over the world will have an opportunity to receive image data and digi-talker signals transmitted from the satellite.

A downlink on 435.130 MHz has been coordinated by the International Amateur Radio Union (IARU) for ClarkSat-1. The ClarkSat-1 team requests signal reports sent to “[email protected]”. Satellite status reports will be posted on X.com @sat1_AMBITIOUS

WRC-23 Concludes with Wins for Amateur Radio

After four hectic weeks of the 2023 World Radiocommunication Conference (WRC-23), and a preceding week of Radiocommunication Assembly meetings, WRC-23 concluded on Friday, December 15. Amateur radio fared very well overall, despite the enormous pressures across the radio spectrum from LF to terahertz. This is a tribute to the effort of the International Amateur Radio Union (IARU) team, who at times had to work from 8:00 a.m. to as late as 2:00 a.m. the next morning, as well as on the weekends.

At the top of the amateur radio priority list was Agenda Item (AI) 9.1b, regarding the coexistence of the secondary amateur and amateur-satellite allocation with the primary radionavigation satellite service in the 1240 – 1300 MHz band. This had seen 4 years of strenuous effort prior to WRC and resulted in a recommendation being agreed upon at the Radiocommunication Assembly, followed by WRC-23 participants agreeing to mention the recommendation in a new footnote for the allocation. Both the recommendation and the footnote are an excellent outcome for the amateur services.

Other items were relevant to the amateur service and were prioritized beforehand:

AI 1.12: 40 – 50 MHz radar sounders. These are now largely limited to the polar area.

AI 1.14: 231.5 – 252 GHz re-allocations for Earth sensing. Fortunately, our secondary 241 – 248 GHz allocation is unchanged, and the primary allocation of 248 – 250 GHz is unaffected.

AI 9.1a: Space weather sensors was an item of major interest. A clear definition for such sensors was confirmed, with frequency protection being agreed upon as an agenda item for WRC-27.

AI 1.2: More broadband in the 3.3 GHz and 10 GHz bands (in Region 2). This is a difficult challenge, as the amateur services are secondary with numerous (mainly South American) countries allocating mobile broadband by way of footnotes. Instead of a region-wide designation for IMT at 10.0 – 10.5 GHz in Region 2, there is a footnote limited to a dozen countries.

WRC-23 agreed to an agenda for the next conference under AI 10. This AI had an unprecedented number of proposals for WRC-27 and preliminary ones for WRC-31. Following the relatively quick agreement on AI 9.1b, the IARU team switched most of its efforts to the following future proposals to reduce the impact on the amateur services, as numerous amateur bands were under consideration.

WRC-27

The WRC-27 agenda will have 19 items. The following are the most relevant to the amateur services:

1300 – 1350 MHz: A previous proposal for this band, adjacent to 23 centimeters, was suppressed, providing certainty for our secondary allocation.

Space Weather: This potential AI was initially very concerning, as the 0.1 – 20 MHz and 28 and 50 MHz bands were initially under consideration, until concerns were raised, and a team effort resulted in these allocations being removed from the topic.

Lunar Communications: This future agenda item initially included 70 centimeters and other bands where Earth-moon-Earth could be restricted. Fortunately, the UHF aspect of this AI was modified to exclude 430 – 440 MHz.

10 GHz: We were fortunate that this band was withdrawn from another round of consideration for mobile broadband, especially in Region 1.

WRC-31

A record number of preliminary item resolutions were agreed on. The following two are especially relevant:

Wireless Power Transmission (WPT): Both near-field and beamed are being considered as part of the International Telecommunication Union radio regulations, whilst minimizing the impact from interference.

275 – 325 GHz Allocations: This will include an opportunity for the amateur and amateur-satellite service.

The IARU team worked effectively to minimize the amateur bands from future studies, which is a great result for amateur radio.

IARU is very pleased with the overall result of WRC-23. The IARU team has already started to discuss and consider how to engage and resource for the next cycle leading up to WRC-27. IARU WRC Coordinator and Vice President Ole Garpestad, LA2RR, expressed his pleasure with the results and complimented the extraordinary effort of the dedicated team of IARU volunteers who worked long hours to achieve the results that will benefit all amateurs.

The IARU team includes ARRL Technical Relations Specialist Jon Siverling, WB3ERA. WRC-23 ran from November 20 – December 15, 2023.

ARISS NEWS

No contacts have been scheduled from 2023-12-21 to 2024-01-14. The complete schedule page has been updated as of 2023-12-21 05:00 UTC.

SSTV from the ISS was to be sent on 145.800 MHz using the PD120 format. The event was scheduled for Sat 2023-12-16 at 10:15 UTC through Tue 2023-12-19 around 18:00 UTC. Unfortunately there is an issue that is still attempting to be resolved, so no signals were received. Hopefully the event can be rescheduled in the near future. The Service Module radio is temporarily stowed.

As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol.

The crossband repeater continues to be active (145.990 MHz up {PL 67} & 437.800 MHz down), but operation has been interrupted due to undocking maneuvers this past week. If any crewmember is so inclined, all they have to do is pick up the microphone, raise the volume up, and talk on the crossband repeater. So give a listen, you just never know.

Note, all times are approximate. It is recommended that you do your own orbital prediction or start listening about 10 minutes before the listed time.

In addition, commands from mission controllers on Earth take 22.5 hours to reach Voyager 1, which is exploring the outer regions of our solar system more than 15 billion miles (24 billion kilometers) from Earth. That means the engineering team has to wait 45 hours to get a response from Voyager 1 and determine whether a command had the intended outcome. (ANS thanks NASA for the above information)

ARISS Marks 40th Anniversary of STS-9 with Special Slow Scan Television Event

In a collaborative effort spanning ARISS teams worldwide, a special Slow Scan Television (SSTV) event is currently underway to mark the 40th Anniversary of NASA Space Shuttle mission STS-9. SSTV transmissions from the International Space Station (ISS) are being broadcast on 145.800 MHz using the PD120 format. The scheduled times for the event are from December 16 at 10:15 UTC | 5:15 AM ET through December 19 around 1800 UTC | 1:00 PM ET.

On November 28, 1983, the Space Shuttle Columbia carried Owen Garriott, W5LFL (SK), into orbit. He was equipped with a specially customized Motorola MX-340 two-meter handheld radio and an antenna attached to the shuttle’s window. The first amateur radio contact from space took place shortly before crossing the west coast on December 1, 1983, when Columbia executed a roll maneuver exposing the antenna toward Earth. W5LFL began calling CQ, and at 02:38 UTC, Lance Collister, WA1JXN, in Frenchtown, MT, answered the call, marking the first amateur radio QSO with a human in space.

A flurry of QSOs followed over the next several days before Columbia returned to Earth on December 8th. Notable amateur operators in the log included Senator Barry Goldwater, K7UGA, and King Hussein of Jordan, JY1. Slow Scan Television has also been an integral part of Amateur Radio in Human Spaceflight since its early days, with Tony England, WØORE, paving the way by sending ten images via Slow Scan Television on Space Shuttle Challenger mission STS-51F in the summer of 1985.

Answers to your Frequently Asked Questions (FAQ) about this ISS Slow Scan Television Event, such as how to decode SSTV images and track the ISS, can be found at https://www.spaceflightsoftware.com/ARISS_SSTV/faq.php. You can apply for the ARISS SSTV Award by uploading your decoded image and completing the Application Form using the information provided at https://ariss.pzk.org.pl/sstv. Don’t forget that you can receive a QSL Card from the International Space Station by receiving and decoding a SSTV image. More information about how to obtain a QSL Card can be found at https://www.ariss.org/qsl-cards.html.

ARISS (Amateur Radio on the International Space Station) hopes that you can participate in another exciting International Space Station SSTV event. This is a great opportunity to share the magic of amateur radio with your friends and family. Watch for event updates to be posted on X (formerly Twitter) at https://twitter.com/ARISS_Intl.

HADES-D Satellite: Successful Telecommand Response and FM Repeater Tests Ongoing

The HADES-D satellite, launched aboard SpaceX’s Transporter-9 (TR-9) mission on November 11, 2023, has successfully completed a month in orbit. AMSAT-EA reports that, following its separation from the ION SCV-013 Orbital Transfer Vehicle two weeks ago, HADES-D is responding well to telecommands from the ground control station.

Current tests on the FM voice repeater show promising results, demonstrating its effectiveness. However, adjustments to the squelch level are under consideration due to the current configuration requiring increased power for activation. HADES-D’s health status has been confirmed through telemetry, CW, and FM voice beacon receptions from various Earth locations.

Telemetry signals in FSK, CW, and FM voice beacon, operating at 436.666 MHz downlink, transmit to Earth at 0.25 Watts. Demodulation and decoding software for satellite telemetry are available on AMSAT-EA’s website under the Project tab (https://www.amsat-ea.org/proyectos). The FM repeater, with a 40mW power output, may require a robust antenna for optimal receive performance.

Developed alongside the URESAT Antonio de Nebrija, both utilizing the pocketQubes 1.5P platform, HADES-D features advanced solar panels and increased processing capacity. These advancements enable the satellite to transmit telemetry and repeat signals at higher speeds. The incorporation of an FM transponder for voice communications also allows for message retransmission in FSK. Efforts are ongoing to confirm the final Two-Line Elements for streamlined operations.

WRC-23 Reaches Acceptable Conclusion on 23-Centimeter Issue

The International Telecommunication Union (ITU) World Radiocommunication Conference 2023 (WRC-23) continues through December 15, 2023, in Dubai, United Arab Emirates (UAE).

The International Amateur Radio Union (IARU)’s primary effort focused on Agenda Item 9.1 topic b to address amateur use of the 23-centimeter band and co-frequency use by several radionavigation satellite service (RNSS) systems in the 1240 – 1300 MHz band.

IARU’s work that began four years ago with a preparatory study in the ITU Radiocommunication Sector (ITU-R) to address this agenda item has finally come to a close. Our concerted engagement in the ITU-R working parties, study groups, and WRC preparatory meetings ensured that the amateur services were properly represented during the development of two published ITU-R reports: M.2513 and M.2532. An ITU-R Recommendation, M.2164, followed these, which formed the basis for the discussions at WRC-23.

During the WRC-23 deliberations, strong positions were expressed by all parties involved.

The result is a well-supported compromise for a footnote in the Radio Regulations regarding amateur and amateur satellite service operation in the 1240 -1300 MHz range. The footnote reminds administrations and amateurs of the need to protect the primary RNSS from interference, and it provides guidance for administrations to allow both services to continue to operate in this portion of the spectrum.

Administrations are the bodies that govern amateur radio in their respective countries, such as the Federal Communications Commission (FCC) in the United States.

The Conference Plenary compromise was formally adopted on December 8 and is not subject to further consideration during the final week of WRC-23. The IARU team continues its work on other WRC issues, including developing agendas for future conferences.

IARU President Tim Ellam, VE6SH, noted, “This is a very good result for the amateur services. The decision reached at WRC-23 on this agenda item makes no change to the table of allocations nor incorporates by reference M.2164 into the Radio Regulations. The addition of a footnote that provides guidance to administrations in the event of interference to the RNSS is a good regulatory outcome for amateurs and the primary users of this band.”

The WRC also agreed to suppress Resolution 774, which closes the issue and satisfies the agenda item. Read more in ARRL News at https://www.arrl.org/news/wrc-23-reaches-acceptable-conclusion-on-23-centimeter-issue

How the 18th Space Defense Squadron Averts Catastrophe at 17,000 Miles Per Hour

In the vast expanse of space, where countless manmade objects hurtle through Low Earth Orbit at speeds exceeding 17,000 miles per hour, a dedicated group of guardians stands watch to prevent potential collisions that could disrupt crucial communication, navigation, and scientific satellites. The 18th Space Defense Squadron (SDS), part of the Space Force, operates from its headquarters at Vandenberg Space Force Base, California, employing advanced technology and surveillance systems to track and identify potential collision risks in real-time.

The 18th SDS, often referred to as the “lighthouse of space,” utilizes the U.S. Space Surveillance Network (SSN) to monitor over 45,000 objects in Earth’s orbit. Ground-based sensors, including the Ground-Based Electro-Optical Deep Space Surveillance System, capture rapid digital photos of the night sky, revealing satellites as tiny streaks. Computers analyze these streaks to calculate the satellites’ positions, providing vital data for collision risk assessments, as explained in a recent press release from the Space Operations Command.

Key components of the SSN include ground-based radar systems such as the AN/FPS-85 and AN/FYS-3 Phased Array Radars, capable of tracking hundreds of targets simultaneously. The ‘Space Fence,’ located in the Marshall Islands, employs an array system that broadcasts constant bands of energy, tracking objects passing through its coverage. On-orbit platforms like the Space-Based Space Surveillance satellite ensure year-round tracking above earthly obstructions like weather and daylight.

Maintaining an ever-growing catalog of space objects on Space-Track.org, the 18th SDS collaborates with its counterpart, the 19th SDS, to predict satellite trajectories and avert potential collisions. In the crowded expanse of low Earth orbit, the squadron remains vigilant, recognizing the heightened risk posed by unexpected satellite fragments that could lead to disastrous collisions.

Space Operations Command (SpOC) recently outlined four categories of fragmentation events: anomalous debris-causing events, breakup events, collisions, and mission-related events. Anomalous events occur due to factors like corrosion or fatigue, leading to slow-speed fragment dispersal. Breakup events, generating large amounts of rapidly spreading debris, can be unintentional or intentional, as seen in anti-satellite missile tests. Collisions, exemplified by the 2009 incident involving a Russian military satellite and a commercial Iridium satellite, prompt heightened awareness and response. Mission-related events involve the fragmentation of payloads or unintentional separation of non-payload components.

Members of the 18th SDS remain vigilant for changes in orbital parameters, indicators of potential satellite stress or gas release, which could precede fragmentation events. Specialized software assists in tracking satellite trajectories and determining the origin and trajectory of debris in case of fragmentation. Timely warnings to affected satellite operators enable them to make necessary adjustments, minimizing collision risks.

Despite the 18th SDS’s capabilities, over a million objects under 10 cm remain untrackable but pose significant collision threats. The act of maneuvering to avoid collisions consumes satellite fuel and shortens their lifespan. Recognizing the limitations, a recent call by the research group RAND advocates for an international space traffic management system (STM) to enhance coordination and communication among satellite operators.

The current state of managing space objects is described by RAND researchers as “informal, ad hoc, and often ill-coordinated,” approaching a tipping point. Urging proactive governance structures, the researchers emphasize the need for the space community to build systems ensuring the safety and sustainability of critical space assets, services, and activities before a crisis necessitates action.

CubeSat Technology and 3D Printing Combine for Emergency Broadband in Disaster Zones

Researchers from the Centre Tecnològic de Telecomunicacions de Catalunya (CTTC), the University of Luxembourg, and the Universitat Oberta de Catalunya (UOC) have developed a nanosatellite technology aimed at delivering swift emergency broadband connectivity to disaster-stricken regions. This innovative solution combines CubeSat technology with 3D printing, allowing for rapid deployment to enhance communication for emergency services in complex situations.

Professor Carlos Monzo Sánchez of the Universitat Oberta de Catalunya emphasizes the project’s significance, stating, “Our project provides a solution that means a communications network to provide help in emergency situations can be established quickly.” The core technology is the CubeSat standard for nanosatellites, known for their cost-effectiveness and small size, manufactured on a 3D printer in just 90 minutes.

The CubeSats are then elevated above disaster zones using balloons, utilizing LoRa (low-power long-range radio) communication with the ground. Raúl Parada, a researcher at CTTC and the paper’s first author, explains, “Our solution enables communication over long distances and provides a scalable system for a large number of users that is reusable anywhere and at any time.”

The team’s prototypes leverage the Semtech SX1278 LoRa transceiver, connected to a simple metal ruler antenna. The 1U CubeSat, housing the transceiver, is equipped with a sensor package comprising a Bosch Sensortec BME280 environmental sensor, a TDK InvenSense MPU-9250 inertial measurement unit (IMU), a Hanwei MQ-135 air quality sensor, and a Roithner LaserTechnik GUVA-S12SD ultraviolet light sensor. These sensors are linked to an Arduino Nano microcontroller, with a GPS receiver added later to facilitate satellite recovery.

Emphasizing the practicality of their design, Monzo explains, “Our solution is designed to provide a rapid service in complex scenarios, and as such, we have prioritized its ease of deployment over its use as a telecommunications solution in normal situations.” The researchers aim to refine the infrastructure further, focusing on minimizing deployment times and ensuring adaptability to a wide range of situations.

The team’s work has been published in the journal Aerospace under open-access terms, marking a significant stride in leveraging technology to enhance emergency response capabilities in disaster-stricken areas.

Satellite Shorts From All Over

+ AO-73 (FUNcube-1), managed by AMSAT-UK and AMSAT-NL, has reactivated its transponder after a meticulous year of battery management. Launched a decade ago, the satellite faced challenges with its battery struggling to reach the nominal 8.3V charge. Recent efforts, including strategic transmitter shutdowns during eclipse periods, have improved the situation. The battery voltage now varies between 8.13V in sunlight and 7.8V at the end of an eclipse, a significant improvement. AO-73 is currently transmitting low-power BPSK telemetry on 145.935MHz, featuring an inverting mode U/V transponder uplink ranging from 435.130 to 435.150 MHz, with a downlink set at 145.970 to 145.950 MHz. The satellite maintains a high spin rate of approximately 30 rpm, requiring manual tuning for the 70 cm input due to the receiver’s temperature drift. This development reopens exciting opportunities for radio operators interested in exploring AO-73’s capabilities after its temporary hiatus.

+ NASA’s Voyager 1 probe, now in interstellar space, is experiencing a communication glitch, preventing the transmission of scientific or systems data. The 46-year-old spacecraft can receive commands, but its flight data system (FDS) is no longer communicating as expected with the telecommunications unit (TMU). The FDS compiles data into a package for transmission, but it’s currently stuck in a repeating pattern of ones and zeros. Voyager’s engineering team is investigating, but a solution may take weeks. The spacecraft’s age and technology from the 1970s present unique challenges, and previous malfunctions required creative software workarounds. Despite past issues, finding solutions for Voyager’s challenges is a slow process, involving consultation of decades-old documents.

+ Blue Origin is set to resume New Shepard suborbital launches no earlier than December 18th, marking the vehicle’s first potential flight in over 15 months. The uncrewed mission, NS-24, will follow a mishap in September 2022 when a structural failure in the BE-3PM engine led to a capsule landing safely while the propulsion module crashed. The Federal Aviation Administration closed its investigation in September 2023, outlining 21 corrective actions for Blue Origin, including technical modifications and organizational changes. The delay in resuming flights prompted speculation about the company’s priorities, but it has since won a NASA contract for a lunar lander, introduced an orbital transfer vehicle, and progressed with the New Glenn orbital launch vehicle and Orbital Reef space station projects. During this hiatus, Virgin Galactic began commercial service with its SpaceShipTwo, VSS Unity, but announced plans to shift to quarterly flights in 2024 and eventually halt operations to focus on new suborbital vehicles.

+ NASA astronaut Frank Rubio grew tomatoes in space using hydroponic techniques to demonstrate space agricultural methods on the International Space Station (ISS). After harvesting one of the first tomatoes grown in space, Rubio misplaced it during a public event with school kids, sparking a humorous search on the ISS. In the microgravity environment, anything unanchored can float away, and despite spending hours searching, Rubio never found the tomato. The mystery ended when the remaining ISS crew announced they had located the tomato, clearing Rubio of suspicions that he had eaten it. Rubio’s historic mission on the ISS, lasting over a year, set a record for the longest a US astronaut has spent in microgravity, initially planned for six months.
