BuzzSat Satellite Meteorology Course Now Available

The AMSAT Youth Initiative is pleased to introduce the first in its series of “Satellites in Space Help Us Live a Better Life on Earth” online courses!

Title screen from the Satellite Meteorology online course (Image: AMSAT)

An “Introduction to Satellite Meteorology” explores the many ways that NOAA satellites help meteorologists predict the immediate weather and long-term climate behavior to make our lives more enjoyable and safer. It is designed for students Grades 8-12.

Each chapter has 40-50 pages and is expected to take perhaps 30 minutes per chapter. If you leave the course, it will remember where you left off so you won’t have to start from scratch.

The course is designed to be “self-standing” so any student, parent, youth leader or teacher can independently utilize the course. The courses are free. You can try this course at:

https://buzzsat.com/

Please note that this edition of the course is a beta release. Numerous improvements to the navigation features, clarity of graphics and technical content are scheduled for the next release in June 2025. But we’d love to hear from you! Please send your comments and suggestions to Frank Karnauskas, AMSAT VP-Development at f.karnauskas [at] amsat [dot] org.

Future course to be added later this year include how satellites play a critical role in managing:

• Climate Change
• Pollution Control
• Wildlife and Natural Resources
• Navigation
• Satellite Design and Operation
• Space Exploration
• Communications
• Broadcasting
• Military Operations
• And much, much more!

Subject matter experts in any of these areas or educators in the sciences are invited to talk with the BuzzSat team about future course development.

AMSAT Volunteers Power Hamvention Exhibit

AMSAT volunteers kept busy at the organization’s exhibit at the 2025 Dayton Hamvention. Interest level was high among both satellite veterans and hams just wanting information on how to get started on the satellites.

The hot seller at the exhibit was the brand new, updated edition of the book, Getting Started in Amateur Satellites.

The Hamvention AMSAT Forum was held on Saturday afternoon, May 17. The forum featured updates on the organization itself from AMSAT President Robert Bankston, KE4AL, Executive VP Paul Stoetzer, N8HM, and from Frank Karnauskas, N1UW, VP-Development. Frank also updated those in attendance on the AMSAT Youth Initiative, including the “Satellites in Space Help Us Live a Better Life on Earth” online courses (see above).

Jerry Buxton, NØJY, VP-Engineering, provided an overview of upcoming satellite projects and launches in development and Drew Glasbrenner, KO4MA, VP-Operations, discussed efforts to extend the lives of satellites already on orbit.

Prior to the beginning of the Hamvention, on Thursday evening, May 15, AMSAT members and friends gathered at Ticket’s Pub & Eatery in nearby Fairborn, Ohio for what has become a traditional gathering in recent years. More than 40 were in attendance — a record number for this event.

The 16th Annual TAPR/AMSAT Banquet Enjoyed by Many

The 16th annual TAPR/AMSAT Banquet was held at the Kohler Presidential Banquet Center on Friday, May 16. This dinner is always a highlight of the TAPR (Tucson Amateur Packet Radio) and AMSAT (Radio Amateur Satellite Corp.) activities during the Dayton Hamvention. This year’s banquet speaker was Phil Karn, KA9Q, who highlighted developments and use cases for his ka9q-radio software suite for SDR receivers.

Karn was the recipient of the ARRL’s Mary Hobart, K1MMH, Medal of Distinction. He was presented the honor at the ARRL donor reception on May 15, 2025, at the National Museum of the United States Air Force on Wright-Patterson Air Force Base near Dayton, Ohio.

A graduate of Cornell University and Carnegie Mellon University with degrees in Electrical and Computer Engineering, Karn has retired from a technology career including Bell Labs, Bellcore, and Qualcomm. He is co-founder of AMPRnet, is founder and past-President of Amateur Radio Digital Communications (ARDC), a private foundation that exists to support amateur radio and digital communication science and technology through grants and scholarships, and the management of 44Net. Karn continues to serve on the ARDC Board of Directors. The work of ARDC has contributed approximately $30 million to amateur radio since 2020.

Karn has been licensed since he was 15. “It’s been a major factor in my life, directly and indirectly,” he said. Karn views amateur radio as a creative outlet. “I’m an engineer, so I need an outlet for my technical ideas. I’m retired, so amateur radio now fulfills that need. It’s very gratifying to see others using your ideas and works,” said Karn.

Karn’s technical contributions to advance the Amateur Radio Service drive his dedication to the future of education through ham radio. He envisions education having a greater role in amateur radio in decades to come. “Ham radio has always excelled at individual self-learning, but it could do so much more. I’d really like to see the many technical tinkerers outside ham radio join us. I’d like to see much more amateur radio in formal education. HamSCI and the many university small satellite groups are good examples but there could be so much more. Hams will continue to create new technology, usually by working in academia and industry but also as individuals,” he said.

Mary Hobart, K1MMH, was ARRL’s first Chief Development Officer. She passed away in 2021. The medal named in her honor is given to those individuals or couples who have inspired our small community to reach higher with their own philanthropic support of ARRL and amateur radio. In 2023, ARRL honored Michael “Mike” D. Valentine, W8MM (Silent Key), and his wife Margaret “Peg” Valentine with the inaugural Hobart Medal.

JAMSAT Symposium 2025: Satellites, Soldering, and Socials in Tokyo

The Japan Amateur Satellite Association (JAMSAT) successfully hosted its 17th annual general meeting and technical symposium on March 22–23, 2025, at the National Museum of Emerging Science and Innovation (Miraikan) in Tokyo. The two-day hybrid event welcomed both in-person and online participants and featured a diverse program of organizational updates, technical presentations, hands-on outreach activities, and social networking opportunities for the amateur satellite community.

The general meeting, held on the first day at noon, covered official business including approval of the 2024 fiscal report, auditor’s findings, the 2025 project plan, and a proposed revision to the association’s bylaws. JAMSAT members were invited to vote by proxy or attend via Zoom, and participation exceeded expectations. The event was formally recognized as an international meeting, qualifying for discounted use of the Miraikan venue and underscoring its educational and public-service role.

Immediately after the meeting, the two-day symposium began with a series of technical presentations. Topics included the RST (Lehman Satellite Tracker) by JI1SYC, a report on the ultra-compact RSP-03 “Hamorun” satellite, and a briefing on QO-100 operations from Cambodia under the XU7AMO callsign. Other featured talks explored a geostationary payload proposal by AMSAT-DL, the SHF beacon’s status, and technical insights into the Ten-Koh 2 receiver system for 5.8 GHz.

Satellite mission updates were also prominent. Researchers from Chiba Institute of Technology presented results from the SAKURA satellite and previewed its successor, BOTAN. The team from Tokyo Institute of Technology introduced OrigamiSat-2, a CubeSat designed to test a two-layer deployable membrane antenna and high-speed downlink. The final session discussed amateur satellite roles in emergency communications, drawing attention to disaster readiness as a future focus area.

Public outreach remained a strong component of the event. On the morning of March 22, JAMSAT organized the “Touching Satellites” program with support from Icom Inc., offering live satellite demonstrations and electronics workshops for children. An exhibit area featured satellite engineering models and educational posters, while 10 young participants had the opportunity to assemble and solder simple kits under the guidance of volunteers.

A formal dinner was held at the nearby Chinese restaurant Tōen in Telecom Center, drawing a wide cross-section of members for informal conversation and project discussion. The social gathering reflected a return to normalcy following years of pandemic-related restrictions and helped to strengthen the group’s community bonds. JAMSAT plans to publish digital versions of the symposium materials online and encourages continued member engagement through web meetings, field activities, and international coordination.

Changes to AMSAT-NA TLE Distribution for May 16

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.

Satellite Shorts From All Over

+ Congratulations to Benni Riethmueller, DL4BEN, (age 16!) on receiving AMSAT Rover Award #087! To earn the AMSAT Rover Award, participants must accumulate a combined total of 25 points through various achievements in portable satellite operations outside their home grid square. The AMSAT Rover Award was established to recognize and honor the accomplishments of satellite operators who engage in rover operations. Rover operations involve the activation of grid squares outside one’s home grid, utilizing various satellite transponders and modes to establish communication links. A breakdown of the points system along with a list of past AMSAT Rover Award recipients can be found at https://www.amsat.org/amsat-rover-award/. Keep on roving, Benni, and continue to inspire others in the AMSAT community! (ANS thanks Bruce Paige, KK5DO, AMSAT Director of Contests and Awards for the above information)

+ China has granted scientists from six countries, including the United States, access to Moon rocks collected by its Chang’e-5 mission in 2020. Two NASA-funded U.S. institutions—Brown University and Stony Brook University—were selected to study the samples, despite longstanding restrictions on NASA’s direct collaboration with China. The China National Space Administration (CNSA) called the samples “a shared treasure for all humanity” and emphasized its commitment to international cooperation. Experts noted that while U.S.-China space technology exchanges remain limited, lunar sample analysis poses no military concern and aligns with global scientific norms. The Chang’e-5 samples are of particular interest because they appear to be about a billion years younger than those collected during the Apollo missions. CNSA officials stated they intend to maintain an active and open stance in global space collaboration through initiatives like the Belt and Road space information corridor. (ANS thanks BBC News for the above information)

+ The FAA granted environmental approval for up to 25 Starship launches a year at Starbase, a five-fold increase from the previous limit. (ANS thanks The Orbital Index for the above information.)

+ Due to budget cuts, NASA might scale back ISS operations, such as reducing crew size, extending crew missions, and halting upgrades to science instruments. A list of other NASA projects that may be abandoned by budget cuts is at https://www.planetary.org/articles/billions-wasted-mysteries-unsolved-the-missions-nasa-may-be-forced-to-abandon (ANS thanks The Planetary Society for the above information.)

+ Germany’s armed forces are planning to establish a large satellite constellation, aiming to create an independent communications infrastructure similar to SpaceX’s Starlink. The initiative, led by the Bundeswehr, envisions deploying hundreds of satellites to ensure secure and resilient military communications, with potential expansion into remote sensing and other applications. Germany has historically relied on satellite services provided by allies but shifting geopolitical dynamics have prompted a reevaluation of this dependence. The proposed Bundeswehr constellation is intended to ensure sovereignty and continuity in defense operations, even in contested or degraded environments. It would operate separately from IRIS2, the European Union’s own sovereign satellite project aimed at providing broadband internet across the continent.

OpenGD77 Handheld Radio Firmware Aids FM Satellite Operating

An article In ARRL QST magazine, April 2025, pages 35 and 36, provides an overview of an available open source firmware for held-held radios: According to the article, the free firmware can provide some models of analog FM and DMR capable radios with satellite capability including screens showing; polar view graphic, satellite individual predictions, a satellite alarm and the ability to upload Kep’s data into the radio.

Doppler tuning and AOS and LOS information were mentioned in the QST article. View the April 2025 QST issue via this link: https://edition.pagesuite.com/get_image.aspx?w=280&eid=7584fe3f-aae2-4504-82c2-65a4c4f268bf&pnum=first.

ARRL members can access QST supplementary materials which are available via this link: http://www.arrl.org/qst-in-depth. Several YouTube videos about the firmware are live including how to create a code plug for programming a handheld with GD-77 firmware. This unique firmware was introduced several years ago.

The GD77 firmware also includes a number enhancements, including easier DMR related functions. Recent discussion on OpenGD77 was heard via the CSRA Multimode Tech Net from several satisfied users. Information about the net is available on their Facebook Group page: https://www.facebook.com/groups/1138357396634299/

The firmware is now available for use in some models of Radioddity, Baofeng and TYT model radios and have been successfully used on an Anytone 878UV II plus handheld.. A GD77 user guide is available via this link: https://github.com/LibreDMR/OpenGD77_UserGuide?tab=readme-ov-file#readme
and a forum is here: https://www.opengd77.com/

The developer’s site includes this caution statement, “firmware license forbids any form of commercial use of the firmware binary or the source code. Installing the firmware onto the radio will invalidate all FCC certifications and those of other countries’ licensing bodies. However, it is usually possible to back up and restore the original radio firmware.

Update About HADES-ICM

HADES-ICM was deployed last Monday, March 31, at 7:37 UTC from OTV ION-SCV-017. Telemetry data shows the satellite is in good condition. The satellite has already accepted commands and now it is undergoing a testing phase. The final TLE is not yet available but you can use this one (Source SatNOGS):

HADES-ICM
1 98637U 25052X 25092.34373891 .00000000 00000-0 42496-2 0 03

A New Breed of Satellite and Space Focused “Makers” is Emerging

Several threads have come together pointing to a new breed of space oriented individuals who may be attracted to Amateur Radio. Exploding interest in inexpensive small board computers (SBC), satellite specific firmware for handhelds, 3-D printed parts for satellite antennas and soda can size “satellites,” and makers using small board computers.

According to Wikipedia, “maker culture is a contemporary subculture representing a technology-based extension of DIY culture that intersects with hardware-oriented parts of hacker culture and revels in the creation of new devices as well as tinkering with existing ones.” https://en.wikipedia.org/wiki/Maker_culture

Taken as a whole, this points in the direction from which new hams, especially students and young adults, may arise. This article is the first of a series about makers as potential recruits for Amateur Radio clubs. To learn more about makers, simply go to YouTube. YouTube is an abundant source of maker videos with some produced by satellite oriented Radio Amateurs and others.

You may recall that the 3-D printed components and Raspberry Pi (RPi) SBCs have been key components of many recent AMSAT projects. RPi. Is often the SBC of choice, especially in severely volume-restricted cubesats.

For example, the AMSAT CubeSatSim v1.3 hardware including two RPi SBCs and four matching cameras. An excellent overview of AMSAT education with the CubeSat Simulator project sessions were presented by Alan Johnston, KU2Y, the CubeSatSim creator.

Changes to AMSAT-NA TLE Distribution

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/.

The following satellites have been removed from this week’s AMSAT TLE distribution:

DRAGON Fram2 NORAD Cat ID 63427 Splashdown 16:19 04 April 2025
Fram2Ham Provisional Cat ID 90000 Experiment terminated 08:42:50 O4 April 2025

The following satellites have been added to this week’s AMSAT TLE distribution:

TEVEL2-1 NORAD Cat ID 63217
TEVEL2-2 NORAD Cat ID 63218
TEVEL2-3 NORAD Cat ID 63219
TEVEL2-4 NORAD Cat ID 63213
TEVEL2-5 NORAD Cat ID 63214
TEVEL2-6 NORAD Cat ID 63215
TEVEL2-7 NORAD Cat ID 63239
TEVEL2-8 NORAD Cat ID 63237
TEVEL2-9 NORAD Cat ID 63238

Please note that Two/Three Line Element (TLE or 3LE) sets for spacecraft launched in the near future will not be available, and new formats will be used instead. The essence of the problem is that the US Space Force is running out of numbers to catalog new satellites, see https://celestrak.org/NORAD/documentation/gp-data-formats.php for details. AMSAT will continue to disseminate TLE for satellites currently in orbit indefinitely as we do now, but we seek comments regarding the best way to support the amateur satellites of the future. For example, is there any need to augment the weekly e-mail with a new list in one or more of the new formats or is on line access via www.celestrak.org or www.amsat.org sufficient? Please send your comments using the form at https://www.amsat.org/webmaster-contact/ on the AMSAT web site.

Starliner’s Wild Ride

For the first time since they returned to Earth on a Crew Dragon vehicle several weeks ago, NASA astronauts Butch Wilmore and Sunita Williams, KD5PLB, participated in a news conference on Monday, March 31, at Johnson Space Center in Houston. Afterward, they spent hours conducting short, 10-minute interviews with reporters from around the world, describing their mission to test Boeing’s Starliner spacecraft on the vehicle’s first crewed, which launched on June 5, 2024 for a planned 10 days.

After Starliner separated from the Atlas V rocket, Williams and Wilmore performed several maneuvering tests and put the vehicle through its paces. Starliner performed exceptionally well during these initial tests on day one.

More so even than launch or landing, the most challenging part of this mission, which would stress Starliner’s handling capabilities as well as its navigation system, would come as it approached the orbiting laboratory. That’s when trouble started, as several thrusters began to fail. Wilmore had to take manual control of the vehicle, but even more thruster failures ensued.

Boeing’s Starliner spacecraft is pictured docked to the International Space Station. One of the four thruster packs is visible on the service module. Credit: NASA

Essentially, Wilmore could not fully control Starliner any longer. But simply abandoning the docking attempt was not a palatable solution. Just as the thrusters were needed to control the vehicle during the docking process, they were also necessary to position Starliner for its deorbit burn and reentry to Earth’s atmosphere. So Wilmore had to contemplate whether it was riskier to approach the space station or try to fly back to Earth. Williams was worrying about the same thing.

Wilmore said, “We knew that they [Mission Control] were working really hard to be able to keep communication with us, and then be able to send commands. We were both thinking, what if we lose communication with the ground?

“Thankfully, these folks are heroes. And please print this. What do heroes look like? Well, heroes put their tank on and they run into a fiery building and pull people out of it. That’s a hero. Heroes also sit in their cubicle for decades studying their systems, and knowing their systems front and back. And when there is no time to assess a situation and go and talk to people and ask, ‘What do you think?’ they know their system so well they come up with a plan on the fly. That is a hero. And there are several of them in Mission Control.”

Fram2Ham SSTV Transmissions Planned

Astronaut and radio amateur, Rabea Rogge LB9NJ / KD3AID, will be transmitting amateur radio Slow Scan TV images from space during the SpaceX Fram2 mission, planned for launch on March 31.

The Fram2 mission is set to become the first human space flight in polar orbit – flying over the North and South poles. Named after the famous polar exploration ship Fram, which completed voyages to both the Arctic and Antarctica. The SpaceX Falcon 9 rocket will launch four astronauts from Europe and Australia into orbit for 3-5 days.

Rabea Rogge LB9NJ / KD3AID [Photo credit: DLR]

During the Fram2 mission Rabea Rogge, LB9NJ (Norway) and KD3AID (USA), will be operating the onboard amateur (ham) radio system sending SSTV images as part of a high school and university student competition. These SSTV images will also be available to be received by the general public during the mission.

The International Space Station simulated the Fram2 SSTV mode PD-120 transmissions from February 13-17 on 437.550 MHz FM to enable people to gain proficiency in receiving the signals before the mission.

Fram2Ham is an experimental radio competition open to high school and university ages. Rogge will send pictures of three geographical locations via an onboard ham radio, but here’s the twist: they’ll be cut into pieces and mixed up! Participants will receive only fragments of the locations and need to guess where on Earth they are and what their role in polar history was. While anyone can receive the pictures, forming an international team may help you solve the puzzle!

There are several challenges like low transmit power, variations of antenna orientation, and a short, 3-day mission duration, with only a limited time assigned for the SSTV operation. These challenges require operating proficiency and the use of the best attainable radio station and this simulation shall give the possibility to exercise this.

For more information on the Fram2 mission and for youth organizations interested in participating in the Fram2Ham SSTV competition, see https://fram2ham.com/

Alba Orbital Assists AMSAT-EA With HADES-ICM Project

Alba Orbital (UK, USA, Germany) is the world’s leading PocketQube company that has delivered 53 pico-satellites on-orbit to date. These include five PocketQube satellites from three different countries recently flown on-board SpaceX’s Transporter-13 Rideshare mission.

Alba Orbital’s AlbaPod [Photo: Alba Orbital]

The satellites were integrated into Alba Orbital’s PocketQube Deployer, AlbaPod, at their new facilities in Hillington Industrial Estate, Glasgow, the world’s first PocketQube factory. After integration, the cluster of pocket-sized satellites were shipped out to SpaceX and then hitched their ride to LEO.

PocketQubes are highly miniaturized satellites, typically 5 cm cubed per unit (‘P’), that can be launched to orbit for as little as 25K euros via Alba Orbital’s rideshare services. PocketQubes are cost-effective, quicker to build, and provide versatile options for a variety of missions that range from educational projects to advanced technological demonstrations.

Payloads aboard this mission include HADES-ICM – HYDRA SPACE / IC MERCURY / SMART IR [Photo: Alba Orbital]

HADES-ICM, a 1.5p PocketQube, this smallsat is carrying an open voice transponder for the radio amateur community. It will be operated by the non-proft organization AMSAT-EA. The PocketQube includes the UK based Smart IR’s technology experiment that will be conducted on-orbit as well as an icMercury experiment. Inspiring space sustainability text messages that will be broadcasted periodically by HADES-ICM.

Firefly’s Blue Ghost Lander Photographs Eclipse From The Moon

Firefly’s Blue Ghost lunar lander snapped a gorgeous photo of a solar eclipse from the Moon in which Earth covers up most of the Sun, leaving only the so-called diamond ring effect.

[Photo: Firefly Aerospace]

The lander snapped the photo at around 05:30z on Friday March 14, as the Earth slowly blocked a view of the Sun. The solar eclipse on the Moon occurred at the same time as a total lunar eclipse here on Earth. Terrestrial viewers saw the lunar surface turn a red hue.

[Photo: Firefly Aerospace]

The eclipse lasted for around five hours at the lunar landing site in Mare Crisium. Firefly released another image from the earlier part of the eclipse that shows the lander’s solar panel as the Sun starts to hide behind Earth’s shadow.

Firefly’s Blue Ghost lander was launched on January 15 and successfully touched down on the Moon on Sunday, March 2 at around 07:30z. It landed upright, with no issues, unlike the Intuitive Machines lander which toppled over on landing on March 6.

This is Firefly’s first mission to the Moon, so Blue Ghost is packed with ten NASA instruments designed to probe the lunar surface and gather data to (hopefully) support upcoming human missions to the natural satellite. This is all part of NASA’s Commercial Lunar Payload Services (CLPS) initiative.

Not long after sunset at the end of the lunar day on March 16, 2025, the Lander’s batteries were depleted, communications were lost and the spacecraft’s mission was officially declared ended at 23:25z.

Changes to AMSAT-NA TLE Distribution for March 21

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/.

NOTICE: In an effort to minimize confusion between sources of two line element sets, AMSAT is adopting the convention of listing the USSF/NORAD Satellite Catalog name first, followed by any secondary name or names in parentheses. For example, “POEM 4 (BGS ARPIT)” was added recently where “POEM 4” is the name that appears in the U.S. Space Force Satellite Catalog, and “BGS ARPIT” is the name best known within the amateur satellite community. Expect name changes for affected satellites in the coming weeks as this change is fully implemented.

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

Satellite Shorts From All Over

+ The four members of the Crew-9 mission — Nick Hague, KG5TMV; Sunita Williams, KD5PLB; Barry “Butch” Wilmore; and Roscosmos cosmonaut Aleksandr Gorbunov — splashed down in the Gulf near Tallahassee, Florida shortly before 2200 UTC on Tuesday, March 18. Hague and Gorbunov launched to the ISS onboard the Dragon Freedom spacecraft in September 2024 and returned to Earth after logging 171 total days in space. Their colleagues, Williams and Wilmore, returned to Earth with 286 days in space after originally arriving at the space station onboard the Boeing CST-100 Starliner spacecraft launched on June 5, 2024. Prior to the departure of Starliner, two extra seats were created inside Dragon Endeavour (which brought up Crew-8) so that in the case of an emergency, Williams and Wilmore would have a way to return home. Thus, they were never actually “stranded” in space, as some media have reported. (ANS thanks SpaceFlight Now for the above information.)

+ The National Reconnaissance Office (NRO) annual conference will be held October 21-23, 2025. NRO brings together the best in academia and the private sector to keep America at the forefront of space-based intelligence, surveillance, and reconnaissance technology. NRO is soliciting abstracts for paper presentations at the conference. Previous topics included: Quantum Technologies, Artificial Intelligence, Advanced Manufacturing, Remote Sensing, Microelectronics, RF Technologies, Space Situational Awareness, & Other Enabling Technologies. Abstract deadline is April 18, 2025. See https://www.nro.gov/SRL/ for details. (ANS thanks David Vine, WA1EAW, for the above information.)

+ Researchers have broken a distance record in quantum communication by sending a secret encryption key nearly 13,000 km from China to South Africa, using a cheap, lightweight ‘microsatellite’. The satellite was able to send pulses of laser light, put into special quantum states, from a rooftop in Beijing to another at Stellenbosch University near Cape Town. The pulses formed a quantum key that was used to encrypt two images — one of China’s Great Wall and one showing part of Stellenbosch’s campus. The feat, a kind of encryption known as quantum key distribution (QKD), is a step towards being able to send ultra-secure messages between any two locations, however distant. (ANS thanks Nature.com for the above information.)

+ The increasing threat from space debris calls for both higher maneuverability in orbit and a reduction of the amount of junk. British startup Magdrive claims it can help with both, via a new propulsion system for spacecraft that will launch into space for the first time later this year and will be fueled by solid metal. The first incarnation of the Magdrive system — called Warlock — is set to launch into orbit in June 2025. It works by creating power using onboard solar panels to ionize metal. Once detonated, the metal is turned into extremely hot and dense plasma, or electrically charged gas. For now, the system is not refuelable. In the more distant future, however, the system could obtain its fuel from existing space junk, by harvesting dead satellites for metal to use as propellant.

+ In the next few months, from its perch atop a mountain in Chile, the Vera C. Rubin Observatory will begin surveying the cosmos with the largest camera ever built. But the rising number of satellites in orbit can be a problem for scientists because the satellites interfere with ground-based astronomical observations, by creating bright streaks on images and electromagnetic interference with radio telescopes. Until recently, astronomers had no centralized reference for tracking satellites. Now, the International Astronomical Union (IAU) has a virtual Centre for the Protection of the Dark and Quiet Sky from Satellite Constellation Interference (CPS), which serves as an information hub. One of the centre’s tools, called SatChecker, draws on a public database of satellite orbits, fed by information from observers and companies that track objects in space. Astronomers can use SatChecker to confirm what satellite is passing overhead during their observations. (ANS thanks Nature.com for the above information.)
