Highlights of the event included a surprise live telebridge contact with the ISS via K6DUE where students present at the conference were able to ask questions of Astronauts Loral O'Hara and Jasmin Moghbeli aboard the ISS. It was also announced that the repaired HamTV module will launch on the SpaceX-30 resupply mission, scheduled for launch on March 12th. HamTV sends a 2.3 GHz amateur television video signal from the ISS to support student contacts and other projects. Discussions were held regarding the Amateur Radio Exploration (AREx) initiative with plans for amateur radio aboard Lunar Gateway. Teams are currently working with spectrum planners for frequencies between 2.4 and 10.5 GHz and the CAVIAR prototype on-station radio was demonstrated. Lou McFadin, W5DID, received a special achievement award. Lou has been active in amateur radio in human spaceflight since STS-9. The keynote speaker for the weekend was Richard Garriott, W5KWQ. His conference keynote was a retrospective of his father's amateur radio efforts entitled "Owen Garriott, W5LFL, Ham Radio Pioneer" and he also delieved a banquet keynote entitled "Exploration Endeavors in Space: Experiences and Leadership as a Private Astronaut and in Space Communication in LEO, to the Moon and Beyond."

The downlink frequency on which to listen is 145.800 MHz worldwide. *“IES Pedro Simón” Abril High School, Alcaraz, Spain, telebridge via K6DUE* The ISS callsign is presently scheduled to be NA1SS The scheduled crewmember is Loral O’Hara KI5TOM The ARISS mentor is IKØUSO Contact is go for: Mon 2024-03-04 11:21:02 UTC 70 deg Watch for Livestream at https://www.youtube.com/watch?v=9Xgk4YZT5w4 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), 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.

(K5ZM) I’ll be heading back to SGU for some sorely needed R & R and will be there from *Saturday, 2 Mar* through *Saturday, 9 Mar* and leaving on the morning of the 10th. Rove-wise, the main objectives are reactivations of the *DM46/DM47 & DM56/DM57 gridlines*, plus a trip just a bit farther south for the *DM44/DM45 gridline* -that will be new /r for me. Given the windshield time involved, I’m thinking these will take the form of a Mon/Wed/Fri scenario, but that’s not set in stone. I don’t necessarily care about the order in which I do them. Let me know your thoughts. I’ll probably hit DM36 (and of course DM37) and maybe another grid or two in between.

His obituary can be found at https://www.johnsonfuneralhome.net/obits/deacon-george-k-carr-ii/. George was a frequent and friendly presence on amateur satellites for many years. AMSAT extends our condolences to George's family and friends. + Bob Heil, K9EID, became a silent key this past week after a battle with cancer. From the Heil Facebook page: * "Our beloved founder, Dr. Bob Heil, K9EID, is now a Silent Key. Bob fought a valiant, year-long battle with cancer, and passed peacefully surrounded by his family. Bob’s lifelong passion for amateur radio was clear to everyone involved in the hobby. Everything Bob did for the betterment and growth of amateur radio - from his instructional handbooks and countless presentations to his support of the ARRL and youth programs - was based on the foundation and spirit of service. Bob was an Elmer to all of us. While Bob’s presence will dearly be missed, his impact on the hobby and everyone in it will forever be felt. On behalf of Bob to all ham radio operators worldwide, 73."* Dr. Heil was a longtime friend of AMSAT and we extend our condolences to his family and friends. (ANS thanks Heil for the above information.) + After spending over a decade on a mission in space, a defunct 5,000 pound satellite returned to Earth on Feb. 21, splashing down in the Pacific Ocean somewhere between Alaska and Hawaii. After tracking the dead satellite for most of the day, the European Space Agency confirmed the satellite had returned to earth by about 19:30 UTC. ERS-2 launched in 1995 and was initially planned to serve the ESA for three years. However, it remained in operation until 2011, providing data for over 5,000 projects, including tracking Earth's shrinking polar ice, sea levels and atmospheric make-up. The majority of the 2.5 ton satellite disintegrated in Earth's atmosphere, though remaining debris likely landed in the north Pacific. (ANS thanks USA Today for the above information.) + The International Space Station (ISS) took more than a quarter-century, 42 space launches, and $150 billion to build. Voyager Space is cooperating with multiple companies and space agencies, including Europe's Airbus, American defense contractor Northrop Grumman, and -- intriguingly -- Hilton Hotels, to build a "Starlab" commercial space station to replace the aging ISS. On Jan. 31, the Starlab space station team announced that it had hired SpaceX to launch its entire Starlab space station to Low Earth Orbit "in a single mission prior to the decommissioning of the International Space Station." SpaceX will use its new Starship megarocket for this mission. Furthermore, "Starlab will ... be fully outfitted on the ground, and ready to permanently host four crew members in LEO to conduct microgravity research and advanced scientific discovery," say the companies. (ANS thanks Yahoo! Finance and the Motley Fool for the above information.) + India has unveiled four Air Force pilots who have been shortlisted to travel on the country's maiden space flight scheduled for next year. The Gaganyaan mission aims to send three astronauts to an orbit of 400km and bring them back after three days. India's space agency, ISRO, has been carrying out a number of tests to prepare for the flight. The officers were introduced as Group Captain Prashanth Balakrishnan Nair, Group Captain Ajit Krishnan, Group Captain Angad Pratap and Wing Commander Shubhanshu Shukla. If it succeeds, India will become only the fourth country to send a human into space after the Soviet Union, the U.S. and China. (ANS thanks the BBC for the above information.) + SLIM, the wrong-side-up Japanese lander, which had been hibernating through the two-week-long, -130 °C lunar night and the following week of unfavorable illumination angles (due to its aforementioned tipsy state), has somewhat surprisingly responded to commands from JAXA. The mission was not originally designed to survive the frigid night time temperatures. However, in a bit of situational irony, the agency had to shut the lander down again almost immediately due to overheating of the communications equipment in the 100 °C+ lunar mid-day.

The flawless launch took place at Vandenberg Space Force Base, on March 4th at 5:05 p.m. EST, where a Falcon 9 rocket carried 53 small satellites into orbit. While this success underscores the persistent need for such services from satellite developers, it also brings attention to emerging challenges in maintaining space situational awareness. Among the diverse payloads was SONATE-2, a 6U+ CubeSat developed by the University of Wuerzburg in Germany. This satellite serves as a technology demonstration for artificial intelligence hardware, software, and machine learning techniques, coupled with an educational component through the DLR School Lab. SONATE-2's amateur payload includes a VHF transceiver and an AI payload with optical sensors, providing regular SSTV downlinks, an APRS digipeater, and CW beacon. The mission aims to engage students in aerospace and computer science engineering programs, offering practical skills and participation in satellite operations. SONATE-2 reported successful operation, with over 1000 telemetry frames downloaded in the first day post-launch, indicating a safe and stable state of the satellite. [https://www.amsat.org/wordpress/wp-content/uploads/2024/03/SpaceX-Transporter-10-Stack.jpg] The SpaceX Transporter-10 Payload Stack. Annotations by https://twitter.com/GewoonLukas_ [Credit: SpaceX] However, the CroCube mission faced a slight setback, with the first Croatian satellite now scheduled for launch on Transporter-11 in June 2024. This decision, prompted by tightened technical conditions set by Exolaunch and SpaceX, aims to ensure project criteria are met, minimizing risks. CroCube, a 1U CubeSat designed for amateur radio and Earth surface imaging, sees this delay as an opportunity to focus on key activities, including ground station completion, mission promotion, educational events, and finalizing the financial structure. The Transporter-10 mission also witnessed the deployment of various payloads from different companies, showcasing innovation in satellite inspection, proximity operations, and technology testing. Notable deployments include Spire's Lemur CubeSats, Iceye's radar mapping satellites, and Satellogic's imaging satellite. Lynk Global, in the process of going public, launched two satellites to fund its direct-to-device constellation development. [https://www.amsat.org/wordpress/wp-content/uploads/2024/03/Sonate-2_Satellite.png] SONATE-2 is Equipped with Amateur Radio SSTV, Digipeater, and CW Beacon. [Credit: University of Würzburg] Startups such as Unseenlabs, Loft Orbital, Atomos Space, True Anomaly, Quantum Space, and Sidus Space seized the opportunity, deploying their first satellites. This diverse array of payloads highlights the industry's commitment to pushing boundaries in space exploration. Another notable payload, MethaneSAT, developed by Ball Aerospace for the Environmental Defense Fund, aims to track global methane emissions with high-resolution precision, contributing to environmental monitoring efforts. Despite the success of Transporter-10, challenges in space situational awareness have surfaced. Owen Marshall of LeoLabs highlighted a degradation in cataloging objects after launch, particularly in rideshare missions where the median catalog time can exceed two weeks. This delay poses risks to satellite operators' communication capabilities, emphasizing the need for enhanced tracking capabilities in the era of growing satellite deployments. As the space industry evolves, addressing these challenges becomes crucial to ensure the sustainability and safety of activities in Earth's orbit.

On board was the Meteor-M2-4 weather spacecraft, a notable addition to the Meteor-M series, alongside several secondary payloads, including an Iranian micro-satellite dedicated to Earth observation. Developed by the Moscow-based VNIIEM Corporation, Meteor-M2-4, weighing nearly three tons, boasts advanced instruments designed for comprehensive monitoring of global weather patterns, the ozone layer, ocean surface temperature, and ice conditions. Recognized for its military applications by the Russian space agency, Roscosmos, this mission marked a significant stride in space exploration. Meteor-M2-4 encountered delays in its journey, originally slated for a December 26, 2023 launch. However, due to multiple rescheduling, the liftoff finally took place on February 29, 2024. The spacecraft, delivered to the launch site on December 28, 2023, underwent meticulous preparations, including fueling and integration with the launch vehicle, ultimately culminating in a successful liftoff.

The fairing protecting the payload separated during the second stage operation, with subsequent stage separations carefully planned for safe impact zones in the Amur Region and the Sakha Republic. The Fregat upper stage took charge of the final payload deployment, executing precise maneuvers over the Arctic and Antarctica. Approximately 59 minutes and 46 seconds after liftoff, the Meteor-M2-4 satellite was successfully released, accomplishing its primary mission. The Fregat then proceeded to deploy the secondary payloads into their designated orbits.

Known for their accessibility to amateur users, Meteor M satellites operate around 137 MHz, making them receivable with a RTL-SDR dongle and suitable satellite antennas. The satellite also transmits in the L-band, enabling reception with a 60cm or larger dish and motorized or hand tracking. Unlike previous satellites in the series, M2-4 experienced a smooth launch and deployment, with reports indicating excellent signal strength and clear image reception in both VHF and L-band frequencies. Two-Line Elements (TLE's) and the SatDump decoding software (https://github.com/SatDump/SatDump) have been updated to support Meteor M2-4, simplifying access for enthusiasts through Github updates. Space historian Jonathan McDowell shared valuable insights into the flight, detailing each Fregat maneuver and its impact on the satellite cluster. While the majority of the secondary payloads adhered to the expected orbits, anomalies in the deployment of some SITRO satellites prompted further investigation. The launch of Meteor-M2-4 and its accompanying payloads stands as a noteworthy accomplishment for Russia's space program, contributing significantly to global endeavors in weather monitoring, Earth observation, and satellite technology development.

(ANS thanks NASA for the above information) + SpaceX is aiming for the third test flight of its Starship rocket on March 14, as announced through a post on the X platform. The Starship vehicle comprises a stainless-steel reusable upper stage, also known as Starship, and a Super Heavy first-stage booster, standing over 400 feet tall together. A recent critical fueling test at the Starbase facility in Texas involved pumping over 10 million pounds of liquid methane and liquid oxygen into the rocket. The upcoming launch follows two previous test flights in April 2023 and November 2023, where Starship faced issues like failure to separate from the first-stage booster and a subsequent explosion of the Super Heavy. After the second test, the FAA identified seventeen corrective actions, all of which SpaceX claims to have completed, addressing issues related to leak reduction, fire protection, and propellant vent operations. The Starship and Super Heavy, designed for full reusability, are pivotal for NASA's Artemis 3 mission to land astronauts on the moon by 2026. (ANS thanks Brett Tingley, Space.com, for the above information) + NASA has identified a growing air leak on the International Space Station (ISS) located at the end of the Russian service module. The leak, situated in Russia's Zvezda service module, initially released one pound of air per day but accelerated to over two pounds daily in early February. Despite the increased rate, NASA assures that it does not currently jeopardize the safety of the ISS crew or impact the station's operations. Collaboration between the United States, Russia, Europe, Japan, and Canada is underway to address the situation. Roscosmos, the Russian space agency, confirms ongoing monitoring and asserts that there is no immediate threat to the crew or the station itself. The leak is in a three-foot-long area and has prompted precautionary measures, including sealing off the affected vestibule to mitigate further air loss from the rest of the space station. (ANS thanks Will Sullivan, Smithsonian Magazine, for the above information) + The inaugural components for Europe's new Ariane 6 rocket have reached the port of Pariacabo in Kourou, French Guiana, transported by the container ship, Canopée. Manufactured across Europe, the central core arrived on Canopée, which uses sails to reduce emissions and save up to 30% on fuel during its 10-day, 7,000 km journey. The rocket's stages were produced in various European locations, with the main engine and stage integrated in Les Mureaux, France, and the upper stage and insulation in Bremen, Germany. Following transport, the components were offloaded and taken to the Ariane 6 assembly building, a few kilometers away, where they will undergo integration before liftoff. The boosters, already at Europe's Spaceport, are P120C solid propulsion boosters similar to those used for the Vega-C rocket. The central core will be assembled horizontally and then transported to the launchpad, where it will be erected, followed by the addition of boosters and the upper stage, with the goal of a summer launch for Flight Model-1.

A low-resolution Slow-Scan TV (SSTV) image that had been pre-loaded onto the satellite prior to launch was received on March 8. The first wide field of view earth image from the onboard camera was received on March 11. Both images can be viewed at https://www.informatik.uni-wuerzburg.de/en/aerospaceinfo/staff/kayal/research-activities/sonate-2/ [*12.03.2024 First wide field of view image from SONATE-2*] SONATE 2 was built by students and faculty in the Aerospace Information Technology program at at Würzburg University in Germany. It was launched on March 4 as part of the SpaceX Transporter 10 mission from Space Launch Complex 4E in Vandenberg SFB, Calif. Using Doppler measurements, Nico Janssen, PAØDLO, has identified SONATE 2 as object 59112. The telemetry downlink frequency is 437.0254 MHz, just slightly above the published target frequency of 437.025 MHz. Telemetry is in 9k6 G3RUH GMSK AX.25 using a protocol that may be downloaded from https://www.informatik.uni-wuerzburg.de/fileadmin/1003-ifex/2024/SONATE-2_protocol_definition_for_radio_amateurs.xlsx The SSTV downlink is at 145.880 MHz FM using the Martin M1 protocol.

The Starship/Super Heavy vehicle lifted off from the company’s Starbase site at 9:25 a.m. Eastern. The liftoff was delayed by nearly an hour and a half because of ships in restricted waters offshore. SpaceX reported no technical issues during the countdown. [*Starship lifts off on its third integrated test flight March 14. Credit: SpaceX webcast*] The Super Heavy booster fired all 33 of its Raptor engines for nearly three minutes before executing “hot staging”, with the Starship upper stage’s engines igniting while still attached to Super Heavy before separating. The booster then performed burns to attempt what SpaceX webcast hosts called a “soft splashdown” in the Gulf of Mexico, where it would not be recovered. However, the landing burn did not appear to go correctly, and the company later said that the booster broke apart 462 meters above the ocean after lighting several Raptor engines for a landing burn. The Starship upper stage performed its burn, placing the vehicle onto its planned suborbital trajectory. It avoided the fate of the previous Starship launch in November, when the vehicle broke apart late in its burn after catching fire while venting propellant. While in space on its suborbital trajectory, SpaceX opened a payload bay door that will be used on later Starship vehicles for deploying Starlink satellites. It also performed an in-space propellant transfer demonstration as part of a NASA contract where it would move propellant from one tank within the vehicle to another. SpaceX said it was evaluating the data from both tests. SpaceX had planned to perform a brief relight of a Raptor engine on Starship about 40 minutes after liftoff, but the company said on the webcast that this test was skipped for reasons not immediately known. The company later said the engine test was called off because of the vehicle’s roll rates. Several minutes later, the vehicle started reentry. A camera mounted on a flap on Starship provided dramatic images of the reentry, relayed through Starlink satellites. Telemetry was lost about 49 and a half minutes after liftoff when the vehicle was descending through an altitude of 65 kilometers. SpaceX later said on the webcast that it lost contact through both its own Starlink satellites as well as through NASA TDRSS data relay satellites at the same time, speculating that the vehicle may have broken up. While the mission did not achieve all its test objectives, the company considered the launch a success. “What we achieved on this flight will provide invaluable data to continue rapidly developing Starship,” it said in a statement.

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.

Moghbeli, Mogensen, Furukawa, and Borisov are returning after nearly six-months in space as part of Expedition 70 aboard the International Space Station. The Crew-7 mission lifted off at 3:27 a.m. on Aug. 26, 2023, on a Falcon 9 rocket from NASA’s Kennedy Space Center in Florida. About 30 hours later, Dragon docked to the Harmony module’s space-facing port. Crew-7 undocked at 11:20 a.m. Monday, March 11, to begin the trip home. Moghbeli, Mogensen, Furukawa, and Borisov traveled 84,434,094 miles during their mission, spent 197 days aboard the space station, and completed 3,184 orbits around Earth. The Crew-7 mission was the first spaceflight for Moghbeli and Borisov. Mogensen has logged 209 days in space over his two flights, and Furukawa has logged 366 days in space over his two flights. [ *A thermal screenshot showing the successfully deployed four parachutes of the Dragon Capsule as it makes its descent on March 12](Image credit: NASA)* Throughout their mission, the Crew-7 members contributed to a host of science and maintenance activities and technology demonstrations , including a number of ARISS amateur radio contacts. Moghbeli conducted one spacewalk, joined by NASA astronaut Loral O’Hara, replacing one of the 12 trundle bearing assemblies on the port solar alpha rotary joint, which allows the arrays to track the Sun and generate electricity to power the station. The crew contributed to hundreds of experiments and technology demonstrations , including the first study of human response to different spaceflight durations, and an experiment growing food on the space station. This was the third flight of the Dragon spacecraft, named Endurance. It also previously supported the Crew-3 and Crew-5 missions. The spacecraft will return to Florida for inspection and processing at SpaceX’s refurbishing facility at Cape Canaveral Space Force Station, where teams will inspect the Dragon, analyze data on its performance, and process it for its next flight. The Crew-7 flight is part of NASA’s Commercial Crew Program and its return to Earth follows on the heels of NASA’s SpaceX Crew-8 launch, which docked to the station March 5, beginning another science expedition. That crew consists of Matthew Dominick, KCØTOR, Michael Barratt, KD5MIJ, Jeanette Epps, KF5QNU, and Alexander Grebenkin, RZ3DSE.

Originally intended to demonstrate satellite refueling, the mission expanded to include in-orbit assembly, incorporating a 16-foot robotic arm named SPIDER. Despite significant congressional funding, the project faced continual delays and ballooning costs, reaching $1.5 billion with an estimated additional cost of nearly $1 billion for launch. Changes in the satellite servicing market, with a shift towards alternative technologies like Northrop Grumman's Mission Extension Vehicle, contributed to the cancellation. Maxar, the prime contractor for OSAM-1, faced criticism for poor performance, leading to delays and cost overruns, although the company cited other factors like the COVID-19 pandemic. The cancellation impacts approximately 450 workers at NASA's Goddard Space Flight Center, prompting NASA to review strategies to mitigate workforce impacts and consider alternative uses for developed technologies. (ANS thanks Ars Technica, for the above information.) + China's human spaceflight agency, CMSA, is progressing towards its goal of landing astronauts on the moon before 2030. The spacecraft developed for this purpose has been named Mengzhou, translating to "Dream Vessel," for lunar missions, and Lanyue, meaning "Embracing the Moon," for orbital travel. These names were selected through a public contest, with Mengzhou having a variant for low Earth orbit (LEO) carrying seven astronauts and a moon version transporting three astronauts into lunar orbit. The China Aerospace Science and Technology Corporation (CASC) is designing and building the spacecraft and lander, along with a new rocket, the Long March 10. The moon landing plan involves two Long March 10 rockets launching Mengzhou and Lanyue, rendezvousing in lunar orbit, with astronauts descending to the lunar surface. A 440-pound crew rover will accompany the lunar lander. Progress on various mission hardware is reportedly on track, including completed development of the primary spacecraft and technical proposals for launch and landing sites. Recently, models of the rocket, spacecraft, and lander were showcased at an exhibition in Shanghai. (ANS thanks Space.com, for the above information.) + U.S. regulators have approved ground rules for allowing SpaceX and other satellite operators to use radio waves from terrestrial mobile partners to keep smartphone users connected outside cell tower coverage. The Federal Communications Commission voted March 14 unanimously in favor of its Supplemental Coverage from Space (SCS) regulatory framework. SCS providers would operate as a secondary service to companies providing Mobile Satellite Services (MSS) with conventional frequencies already approved for use from space. This means an SCS operator would have to immediately cease operations if they interfere with an MSS provider or terrestrial telco with primary rights. (ANS thanks SpaceNews for the above information.) + A rocket made by a Japanese company exploded seconds after launch on Wednesday, in a spectacular failure for the start-up's bid to put a satellite into orbit. Tokyo-based Space One's 18-metre (60-foot) Kairos rocket blasted off in the coastal Wakayama region of western Japan, carrying a small government test satellite. But around five seconds later, the solid-fuel rocket erupted in fire, sending white smoke billowing around the remote mountainous area as orange flames raged on the ground, live footage showed. Space One said it had taken the decision to "abort the flight" and details were being investigated.

Time to start making plans to attend Hamvention 2024 from May 17-19, 2024 in Xenia, Ohio. This year's Hamvention theme is "Expanding our Community" and AMSAT plans to do exactly that by adding new members and recruiting more volunteers. Led by AMSAT Hamvention Team Leader, Phil Smith, W1EME, preparations are well under way. AMSAT, one of the larger Hamvention exhibitors, will again occupy 1,200 square feet of space at the north end of Building 1, also known as the Maxim building. This booth area has always been ideal for AMSAT because of the ample fresh air and easy access to the outdoor satellite ground station. Exhibits will feature members of the engineering team, CubeSatSim, Beginner's Corner, merchandise sales, Youth Initiative, software demonstrations and membership sign-ups. Also featured at this year's booth is information and sign-ups for the revitalized AMSAT Ambassador program. AMSAT will host its annual AMSAT Forum on Saturday from 1:10 to 2:10 in Room 2. Moderated by Phil Smith, W1EME, Robert Bankston KE4AL, AMSAT President, will highlight recent activities within AMSAT and discuss some of our challenges, accomplishments, projects, and any late breaking news. AMSAT Engineering Program: Jerry Buxton, N0JY, AMSAT Vice President for Engineering, will talk about the Current and upcoming satellite missions. AMSAT Education: Alan Johnston, KU2Y, AMSAT Vice President Education Relations will talk about the AMSAT CubeSat Simulator. AMSAT Operations: Drew Glasbrenner, KO4MA, Vice President Operations, will discuss current satellites and operations. AMSAT Development: Frank Karnauskas, N1UW, Vice President of AMSAT Development, will report on AMSAT Youth Initiative and its features. Another attraction will be the 15th annual AMSAT/TAPR Banquet on Friday at 18:30 EDT. 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 will be Bill Reed, NX5R, AMSAT Volunteer Engineer, who will highlight the forthcoming PACSAT digital communications payload. The 2023 Hamvention attendance was 33,861, which is more than 2,000 greater than 2022 and even surpassed the previous pre-pandemic attendance record at the Greene County Fairgrounds and Expo Center of 32,472. This year's attendance is expected to be another record breaker. As a bonus, this year's Hamvention will also be the site for the ARRL 2024 National Convention. If you are planning on attending this year's Hamvention, please consider volunteering to help staff the AMSAT booth for an hour or so. Please send an email to volunteer [at] amsat [dot] org if you think you can help. For complete information on Hamvention 2024, go to https://hamvention.org/.

Join the AMSAT President's Club today and help Keep Amateur Radio in Space! https://www.amsat.org/join-the-amsat-presidents-club/ ------------------------------ AMSAT VP-Engineering Reviews GOLF Satellite Development Recently AMSAT News Service had the opportunity to interview Jerry Buxton, N0JY, AMSAT Vice President of Engineering, about the GOLF satellites that are currently in development. ANS: Jerry, the AMSAT engineering team is developing the GOLF (Greater Orbit, larger Footprint) satellites. What is the idea behind these satellites and the kind of functionality that will be added? JB: "Our original thought was for GOLF is to teach us how to go to Highly Elliptical Orbit (HEO.) Higher orbits have greater challenges than the satellites for LEO orbits we have built most recently. These are challenges like the higher radiation environment that the satellite must endure and controlling the satellite at higher altitudes. "We've had a significant additional requirement that has been added since GOLF was originally conceived. We must be able to deorbit the satellite on command. This is a pending FCC regulation. It is also likely that we will be required to move the satellite to avoid orbital debris in the future. To do this we have to be able to accurately know where the satellite is which requires a Global Navigation Satellite System (GNSS), which direction it is pointing which requires adding an Attitude Determination Control System (ADCS), and have a propulsion system to move it. This is not trivial. "Of course, we want to add more and more capabilities which require more power. "So, the purpose of the GOLF satellites is technology development, but they will have radios on board. Once they are up and we have proven the technology we will have another satellite that amateur radios operators can use." ANS: "What is the advantage of higher orbits?" JB: "Most of our current satellites are LEO, so we have about a 10 to 15-minute window to work the satellite. With higher orbits, the satellites will have a larger footprint (the signal will cover a larger area of the earth) and will be available or visible for longer periods of time. ANS: "Could you tell us a little more about how GOLF is being developed?" JB: "We will design and build the systems if we can, and we will acquire (buy) the functionality if need to. We are also using a stepped approach to capability development. We may fly the Attitude Determination Control System (ADCS) on the first satellite, add the propulsion system on the next satellite and so on. ANS: "Interesting! What else makes GOLF different from our previous satellites?" JB: "GOLF-TEE will have a new 3U space frame with deployable solar panels, which will flop open and lock into place. The solar cell system is an in-house design. It will have 14 cells on the satellite space frame and 28 on the deployable solar panels for a total of 42 cells, a significant increase in available power. "GOLF will have a radiation tolerant IHU (Internal Housekeeping Unit, or on-board computer.) It uses an automotive grade 32 bit ARM processor which has two processors. One is the primary. If one locks up the other takes over. The computer cores are in different areas of the chip and are at 90 degrees to each other, which lowers the likelihood of radiation affecting both processors. "We're adding microwave bands with a 10 GHz downlink experiment for increased data speed, that can also be used as a transponder downlink. This is a purchased radio. It has been a little bit of a challenge to fit the SDR into GOLF because it doesn't fit the normal layout. "GOLF will be much more complex than the FOX satellites. This complexity will increase the cost. This is because of the added capability the engineering team is developing like the additional solar panels as well as the selection and integration of purchased items like the ADCS or the 10 GHZ SDR radio." ANS: "Wow, the GOLF satellites will be a give us exciting new capabilities! When will they be launched?" JB: "The first is GOLF-TEE, which will be ready for launch in Q4 of 2025. GOLF-1 will be ready follow in Q4 of 2026. We should have some data and lessons learned from GOLF-TEE by then. "Here is a little more detail on the launch; GOLF-TEE and GOLF-1 have been approved by NASA as sound concepts and eligible for the ELaNa program. This program will pay for launch up to $300k of launch cost (covers everything up to a 3U satellite to LEO) and they will look for a launch that we can ride on. (We don't get to choose just when we launch.) A launch is not a guaranteed, but they always have found a ride for us." ANS: "Thank you, Jerry, for helping us understand these important new satellites!"

They transmit with high power and gain antennas so they are easily received with a simple dipole antenna and a $30 RTL-SDR dongle that plug into a computer that most everyone owns. They are always on and transmit data that is actually fun and usable: very clear pictures of ones' own locale that is easily decoded with free software. >From this first experience, it is a simple jump to tracking and copying the ARISS voice and APRS repeaters, and from there getting a Technician class license and inexpensive handheld. In addition to the NOAA low earth orbit polar meteorology satellites, the Russian METEOR M2-4 was recently added on February 29, 2024. It was launched into a 800km sun-synchronous orbit with a 98 degree inclination from the Vostochny Cosmodrome aboard a Soyuz 2 rocket. Having achieved orbit, it is currently undergoing testing and calibration. There is currently no information when setup will be completed, but it did take several months for NOAA to get the NOAA-21 satellite running. Once it is functioning it will begin transmitting its low-rate picture transmission (LRPT) imagery on 137.1 MHz and/or 137.9 MHz. The antennas are right-hand circular polarization but are easy received with a home-made three-element yagi or even a simple dipole. Complete information on suitable SDR receivers, and free receiving and decoding software can be found at rtl-sdr.com. A simple You Tube search on the topic will also provide you with enough demonstration videos to help get you started. More information at https://www.rtl-sdr.com/.

This month Gabe has posted a 24-minute video on how to use parts from an old security pan-tilt camera mount to build an az-el satellite rotator. The rotator motors are controlled by software based on the Australian School Amateur Radio Club Network (SARKNET) Rotator Mark I Arduino code. The software can be run on either an Arduino device or on a PC laptop. Gpredict is used in this example to track the satellites. Gabe uses the rotator to steer a small dish but it looks strong enough to handle a lightweight yagi such as an Arrow or Elk if suitably counterweighted. Even if you aren't interested in building this az-el rotator, Gabe's video is a fascinating look at how an inventive mind and resourceful scrounger can make something actually useful. Ham radio as it should be! More information at https://www.rtl-sdr.com/.

Weekly updates are completely adequate for most amateur satellites. Elements in the TLE bulletin files are updated daily. TLE bulletin files are updated to add or remove satellites as necessary Thursday evenings around 2300 UTC, or more frequently if new high interest satellites are launched. More information may be found at https://www.amsat.org/keplerian-elements-resources/ The following satellite has been added to this week's AMSAT-NA TLE Distribution: SONATE-2 - NORAD Cat ID 59112 Downlinks on 437.025 MHz, 145.825 MHz, 145.840 MHz and 145.880 MHz have been coordinated by the IARU. Thanks to Nico Janssen, PA0DLO, for the identification. The following satellite has been removed from this week's AMSAT-NA TLE distribution: BeliefSat-0 NORAD Cat ID 58695 End of mission. This mission was interesting as BeliefSat-0 is not a free flying satellite. Instead it is a "hosted payload" on a larger platform, in this case the spent upper stage of an Indian launch vehicle. The stage was modified such that it included solar panels and attitude control, so BeliefSat 0 and other payloads were designed to simply bolt on and plug in to a regulated power source. See https://www.isro.gov.in/POEM-3_Mission_achieves_Payload_objectives.html for details. While BeliefSat-0 and its host POEM-3 remain in orbit for now, it appears that BeliefSat-0 has been shut down as there have not been any successful observations of it in SatNogs for several weeks. POEM-3 will reenter within the next few weeks "leaving zero debris in space" according to the Indian Space Resource Organization.

Alan was one of the first Broadcasting majors at the University of Wyoming and began his career at KATI radio in Casper. He later worked for KCBS-FM and KGO TV in California. As microcomputers emerged in the industry, Alan evolved into a computer technologist, working at Northstar Computers, Fantasy Records, and Dolby Laboratories. During the winter months of 1983 and 1984, he spent time in London as computer consultant to Hollywood film filmmaker, Stanley Kubrick. In retirement, he turned into a travel photographer, touring worldwide and documenting his experiences in still photos and video. First licensed in 1966, he was a consistent voice on RS-44 and an avid experimenter on IO-117 and other digital modes from CM87 in northern California. He earned AMSAT GridMaster Award #62 of which he was very proud, while grateful to the many rovers who worked hard to make that happen for him. We will miss hearing Alan on the birds!

[ANS thanks Abdul Alshahrani, HZ1DG for the above information.] + Tom Van den Bon, ZR6TG has been toying with this idea of adding a "Widget" to his Icom IC-9700. Playing with satellites requires various kinds of software that requires a fully fledged PC connected to the radio for tracking the satellite, controlling the rotator and automatically adjusting for Doppler effect. While all of that software works perfectly fine, Tom always wondered if there wasn't a simpler solution which is always available and ready at the radio. Tom says, "I know there are a few satellite "controllers" available that allow you to do something similar, but I felt that those are either too specific (i.e., only one radio and one rotator) or was lacking some features. My idea around the Satellite Tracking widget is to try and combine everything I need in a single small display."

The implementation is to take place through collaborative cooperation between internal, industrial and amateur radio participants. This activity will consolidate the requirements of the amateur and commercial satellite industry, weigh up different payload options, address the future user segment, develop scenarios for the financing, procurement and operation of such a payload, and investigate possibilities for placement on geostationary platforms. This past weekend, AMSAT-DL released their proposal. AMSAT-UK, along with the British Amateur Television Club, AMSAT-NA, and the UK Microwave Group previously made a separate proposal . AMSAT-DL's proposal is written by the authors Kai Siebels, DH0SK and Matthias Bopp, DD1US. The proposal takes into account the technical requirements and needs of radio amateurs. Various aspects such as orbit, satellite and platform as well as payload are taken into account. Among the possible orbits such as MEO, HEO and GEO, the GEO orbit has proven to be the most suitable due to the extensive experience with OSCAR-100. A good compromise for the orbit position would be at ~43 degrees West to also support Eastern European countries and most of North America. A payload for amateur radio should allow the greatest possible scope for experiments on different bands. Six bands could be used for the uplink to enable experiments with different frequencies. The main uplink band is the 13 cm band, the main downlink band is the 3 cm band. All proposed band / NB transponder combinations can be implemented at the ground station with very reasonable effort. A dedicated AMSAT (Amateur Radio) mission based on an ESA-supported Micro GEO provides opportunities for several additional experiments that support AMSAT’s education, science and development goals to inspire young people with amateur radio technology. Finally, such a mission could also provide an excellent platform for disaster/emergency communications directly via the GEO satellite transponders. Micro GEO and QO-100 Micro GEO satellites are a new class of small geostationary communications satellites. They are around a tenth of the size of traditional geostationary satellites and typically measure just one cubic meter. This smaller size makes them significantly cheaper to manufacture and launch, allowing satellite operators to offer customized regional services or gap fillers that would not be financially feasible with large satellites. The amateur radio payload “QO-100” on the Es’hail-2 geostationary satellite, is a groundbreaking platform for the amateur radio community as it represents the first geostationary payload for amateur radio. The exemplary collaboration between AMSAT-DL, QARS and commercial partners on this project to integrate amateur radio payloads into a commercial satellite is a sign of the ongoing cooperation between the amateur radio community and the commercial space industry. This synergy can open up new avenues for amateur radio projects in space. QO-100 serves as a bridge between traditional approaches and new possibilities, while remaining firmly rooted in the principles of amateur radio. Its presence in geostationary orbit is a triumph for the amateur radio community and a sign that amateur radio can continue to play an important role in the exploration and use of space. SYNCART 2.0 on the Heinrich Hertz satellite The Heinrich Hertz Satellite Mission (also known as H2Sat) is a national, geostationary communications and research satellite. It was planned by the Space Agency of the German Aerospace Center (DLR) on behalf of the BMWi as part of the German government’s space strategy and serves both independent payloads (“hosted payloads”) and the in-orbit verification (IOV) of technologies as well as for research purposes. In July 2012, AMSAT-Germany (AMSAT-DL) proposed an amateur radio payload on the Heinrich Hertz satellite with the name “SYNCART 2.0” . This was a further development of the transponders of the P3-D AMSAT-OSCAR-40 satellite in the X and K amateur radio bands and a beacon in the 76 GHz band. The objectives of the amateur radio payload were as follows: - Development of the geostationary orbit for the amateur radio service - Communication resource for emergency and disaster radio (with low-power, small, simple technology) - In-orbit verification of SDX technologies - Promoting the spread of microwave technology - Gaining new insights by studying propagation conditions in the 76 GHz band for satellite applications - Provision of a signal for the calibration of antennas, converters and receivers, in particular for radio astronomical applications - Stimulating the acquisition of scientific and technical education, especially among schoolchildren and young people, by providing a permanently available satellite resource, e.g. for use in teaching, research and education - Acquisition of concrete knowledge and experience with satellite technologies and corresponding research opportunities in order to provide the space industry with highly qualified specialists. The concept aimed to make efficient and effective use of any remaining H2Sat capacity. The Heinrich Hertz feasibility study was completed in 2010. Planning phase B was carried out from 2011 to 2013. In July 2012, AMSAT-DL submitted its proposal for an amateur radio payload. Unfortunately, important positions on the antenna deck and with the payloads were already occupied at this point. There was also an approach for a Ka/Ka relaying transponder, but its use would have been limited to two small spot beams to northern Germany and southern Germany. At the time, this did not seem justifiable to our members and the amateur radio community in terms of the cost/benefit ratio. After it became clear that an amateur radio payload on the Heinrich Hertz satellite in the proposed form was not feasible, the proposal was finally withdrawn in September 2012. Miraculously, however, a new window opened just a few months later! Initial talks and contacts were held as early as December 2012, which ultimately led to an amateur radio payload on the Es’hail-2 satellite, also known as Qatar-OSCAR 100 or QO-100. Es’hail-2/QO-100 was launched aboard a SpaceX Falcon 9 rocket on November 15, 2018. This project is a joint initiative of the Qatar Satellite Company, the Qatar Amateur Radio Society and AMSAT-DL. The satellite was built by Mitsubishi Electric Corporation in Japan and is located in a geostationary orbit at 26° East.

The ERMINAZ mission is a syndicated multi-PocketQube mission with a total of 7 PQs under the leadership of AMSAT-Germany, which also holds the launch contract with RFA under DLR support. The project is in collaboration between AMSAT-DL, AMSAT-EA (Spain), ESERO-Germany (Bochum Observatory) and Libre Space Foundation (Greece). The mission is to promote, advance and develop knowledge about space and amateur radio. ERMINAZ-1U & ERMINAZ-1V will transmit telemetry, images, provide a digipeat/store/forward functionally to all radio amateurs worldwide. ERMINAZ-1U will operate in the UHF amateur satellite band, while ERMINAZ-1V will operate in the VHF amateur satellite band. Only non-proprietary, open source and documented protocols, accessible to radio amateurs, will be used. This includes CCSDS telemetry, CW beacon, SSDV images, digipeater, AX.25 und possibly other modes. Telemetry and sensor data from radiation sensor and triaxial accelerometer / gyroscope / magnetometer will allow any radio amateur to participate by extending his knowledge about space. In addition, a digipeater and store & forward function will allow licensed radio amateurs to use ERMINAZ-1U/1V as a relay to communicate with other radio amateurs worldwide. The mission will conduct several experiments with different types of modulations, bandwidths, data rates and framing schemes: GFSK with data rate from 9600 up to 19200 GFSK with data rate from 9600 up to 19200 bits/s GMSK with data rate from 9600 up to 19200 bits/s BPSK with data rate from 9600 up to 19200 bits/s QPSK data rate from 19200 up to 38400 bits/s Frames will using three different framing schemes configurable upon the mission requirements: CSDS (residual or suppressed carrier) or IEEE 802.15.4 (preamble, sync) or AX.25. Planning a launch by RFA-Rocket Factory Augsburg AG from SaxaVord Spaceport into a 500km polar orbit not earlier than August 2024 together with UNNE-1 (HADES-E) and MARIA-G (HADES-F) from AMSAT-EA and QUBIK 5 from LibreSpace.

S. Naval Academy Scheduled for 2025 Launch A 3U CubeSat. USNA-16 will provide UHF LoRa digipeater service to the amateur radio service. Additionally, USNA-16 is a university-student educational amateur radio mission. It will test a modular CubeSat design and integration, as well as the efficacy of student-designed passive magnetic pointing scheme for S-band operation. INCHsat payload will provide UHF service to the amateur radio service. In addition INCHsat payload is a university, student lead, educational amateur radio mission. It will test custom designed and built components. Specifically it will test a custom on-board computer, a custom radio (based off the OpenLST), a custom motherboard, and a custom antenna deployment system. USNA-16 is a student educational amateur radio mission. It will test a modular CubeSat design and integration, as well as student-designed passive magnetic pointing scheme. TT&C will occur at UHF (437.235 MHz, will be designated as UHF-TTC in this document) and data downlinks will occur at 2.42GHz, both within the amateur bands and both using the LoRa protocol. This will be the first satellite launched by USNA using LoRa, with a potential future application of APRS over LoRa. USNA-16 will also provide UHF LoRa digipeater service at 437.235 MHz to facilitate communication between amateur operators. INCHSat is a student educational amateur radio mission built by students at the University of Maryland, including the licensee, KC3VBJ. There are no paid employees. The main goal is to enhance the aerospace skills of students in a professional context. The students are learning about satellites and space mission development and space communication by designing, building, and launching a payload onboard a cube satellite. The payload consists of a custom onboard computer, the radio, basic sensors, motherboard, and an antenna deployment system. Communication with the payload will be performed on the 437 MHz band from a ground station that will be constructed on the UMD campus. This payload radio (437MHz) will be designated as UHF-PLD in this document. USNA-16 will have a LoRa digipeater to serve the amateur satellite community. LoRa offers low-power beyond-line-of-sight digital UHF communications to the amateur community. Additionally, USNA-16 is a student educational amateur service mission that communicates on amateur frequencies. This will be the first satellite launched by USNA using the LoRa protocol, with a potential future application of APRS over LoRa. INCHsat payload is for the purpose of the training of UMD students in the construction and development of aerospace components. It also tests the components that we have developed on our own for future missions and research purposes with no commercial benefit. INCHsat payload will have a radio based on the open source OpenLST from Planet Labs to serve the amateur satellite community. INCHsat payload is also a student educational amateur service mission that will be communicating data obtained on amateur frequencies. Pending the mission success the code and schematics of the components used will be published as a cheaper alternative for amateur teams looking to launch a cube satellite.

On October 19, 1989, a monstrous X13 class solar flare triggered a geomagnetic storm so strong that auroras lit up the skies worldwide the following day. Had you been flying around the Moon at that time, you would have absorbed a dose that would most likely kill you within a month or so. This is why the Orion spacecraft that is supposed to take humans on a Moon fly-by mission this year has a heavily shielded storm shelter for the crew. But shelters like that aren’t sufficient for a flight to Mars. To obtain protection comparable to what we enjoy on Earth would require hundreds of tons of material, and that's simply not possible in orbit. The primary alternative?using active shields that deflect charged particles just like the Earth’s magnetic field does?was first proposed in the 1960s. Today, we’re finally close to making it work. Fascinating full article at https://bit.ly/3PANp67 (ANS thanks ARS Technica for the above information.) + Not an April Fool's joke: The U.S. Army has conducted a series of experiments, beginning in 1904 and continuing into the 1970s, on using trees as shortwave antennas. "It would seem that living vegetation may play a more important part in electrical phenomena than has been generally supposed. If, as indicated... in these experiments, the earth surface is already generously provided with efficient antennas which we have but to utilize for communications."
