The LOI expresses strong interest in developing and flying an AMSAT-designed CubeSat payload on one or more of these missions. It highlights the strategic alignment between the opportunity and AMSATâs ongoing GOLF (Greater Orbit, Larger Footprint) program, which is building the technologies and operational experience needed for amateur radio satellites in progressively higher orbitsâfrom LEO through MEO to HEO. A high-Earth deployment would provide an outstanding environment to qualify key GOLF technologiesâparticularly radiation-tolerant electronics, advanced Software-Defined Radio (SDR) transponders, three-axis attitude determination and control, and deployable/steerable solar arraysâin the demanding thermal, radiation, and trajectory conditions beyond low Earth orbit. Such a mission would significantly expand amateur radioâs âlarger footprint,â deliver critical flight heritage, and create clear synergies with NASAâs exploration, technology demonstration, and public engagement goals. The LOI emphasizes AMSATâs long heritage of successful CubeSat missions (including the Fox series flown via NASA CSLI/ELaNa) and its robust portfolio of educational and university partnership programs. These include the CubeSat Simulator Program used worldwide in schools and universities, collaborations such as the radiation experiment from Vanderbilt University and imaging payloads from Virginia Tech on Fox satellites, broader STEM outreach through live satellite contacts and telemetry projects, and active mentorship of student teams and early-career professionals. AMSAT is prepared to deliver a flight-ready CubeSat payload, leveraging its proven engineering pipeline, dedicated volunteer technical team, and sustainable funding model of membership support, targeted donations, and grants. AMSAT proposes a 6U-class spacecraft (<14 kg) featuring deployable solar arrays and an AMSAT-developed amateur radio communications system supporting VHF uplink/UHF downlink plus 5 GHz uplink and 10 GHz downlink. A precursor 3U technology demonstrator, GOLF-TEE, is under construction with completion targeted by the end of the year; if selected, AMSAT would pivot development toward the 6U configuration in collaboration with partners. Ground operations would leverage the global amateur radio community for telemetry reception via AMSATâs analysis tools, supported by dedicated AMSAT command stations. The organization is genuinely excited about the prospect of contributing an AMSAT-developed CubeSat to the Artemis programâadvancing amateur radioâs historic role in space exploration, qualifying technologies for future HEO and lunar missions, and inspiring students and the global public through meaningful educational partnerships.

Developed by Peter Goodhall, MM9SQL, and hosted on GitHub, OscarWatch provides an integrated environment for tracking AMSAT and other amateur satellites, predicting passes, managing Doppler-corrected frequencies, and optionally automating rotator and radio controlâall from a single map-centered interface. <h3 dir="auto">Key Features</h3> OscarWatch is tailored for VHF/UHF satellite operators working FM cubesats (e.g., SO-50, ISS), linear transponders (e.g., RS-44, FO-29), and similar modes. It assumes familiarity with basic concepts like azimuth, elevation, and Doppler but automates the calculations and hardware interactions to let operators focus on making contacts. <ul dir="auto"> <li>Visual Tracking: World map with satellite subpoint, ground track, and footprint overlays (with optional motion arrows and greyline terminator). Includes a polar sky plot relative to your QTH. Support for time scrubbing to preview passes without affecting live hardware. Optional DX station grid marker with live Az/El from the remote location.</li> <li>Pass Predictions: List of upcoming passes with TCA (time of closest approach/max elevation), filters for minimum elevation and duration. Features include a pass planner with multi-station profiles and .ics calendar export, plus a mutual pass finder for two-station coordination.</li> <li>Frequency Management: Built-in transponder database with live Doppler-corrected uplink/downlink frequencies. Supports RX offsets (separate for Voice/CW on linear modes), CTCSS tones, and easy toggling between modes. Includes a transponder database editor for custom additions and updates from the published JSON source.</li> <li>Hardware Integration: Optional serial CAT control for supported radios (including Icom IC-910/9100/9700/705, Yaesu FT-847/817/818/991 series, Kenwood TS-2000 beta) with Doppler tracking, satellite/split modes, and CTCSS handling. Dual-radio support for full-duplex setups. Rotator control for Yaesu GS-232 and EasyComm-compatible controllers (including SPID), with manual park and smart azimuth options for 450Â° rotators.</li> <li>Additional Tools: Voice announcements for satellite rising, automatic pass WAV recording, Cloudlog integration for frequency logging, and live telemetry (Az/El, range, altitude).</li> </ul> OscarWatch does not decode telemetry or serve as primary logging software; it complements existing tools as a pass assistant for home or portable use. TLEs and the transponder database are sourced from <a href="https://tle.oscarwatch.org/" target="_blank" rel="noopener noreferrer nofollow">tle.oscarwatch.org</a>. <h3 dir="auto">Getting Started</h3> Pre-built binaries for Windows, macOS, and Linux are available on the <a href="https://github.com/magicbug/OscarWatch-Tracker/releases" target="_blank" rel="noopener noreferrer nofollow">GitHub Releases page</a>. After installation: <ol dir="auto"> <li>Configure your station location (lat/long/grid) in Settings.</li> <li>Select desired satellites and refresh TLEs.</li> <li>Set up radio and rotator COM ports if using automation.</li> <li>Focus a satellite via the map or pass list to view live data and frequencies.</li> </ol> Detailed operator guides, keyboard shortcuts, and troubleshooting are included in the app's Help menu and the repository's help/ folder. Note that macOS users may need to approve the unsigned app and bundled libraries on first launch. <h3 dir="auto">Supported Hardware Highlights</h3> Radios (serial CAT, native drivers): Icom IC-910/9100/9700/705, Yaesu FT-847/817/818/991 series, Kenwood TS-2000 (beta), with dual-radio options. Rotators: Yaesu GS-232, EasyComm II (SPID/M2/etc.). The project emphasizes custom native drivers for reliable satellite-specific behavior over general libraries like HamLib. OscarWatch is still evolving rapidly (recent versions added in-app updates, multi-language support including Japanese, Simplified Chinese, and Brazilian Portuguese, greyline overlays, mutual pass visualizer, and expanded rig/rotator support).

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<a href="https://www.amsat.org/keplerian-elements-resources/">Â https://www.amsat.org/keplerian-elements-resources/</a>. There are no changes to this week's TLE distribution. <h3>General Perturbations Data Support</h3> AMSAT is pleased to announce that modern forms of what are called General Perturbations data are being disseminated via modern formats including JSON, XML and KVN at <a href="https://newark192.amsat.org/gpdata/current/">https://newark192.amsat.org/gpdata/current/</a>. The reason this change is being made is that we are running out of 5-digit catalog numbers and the TLE format is not viable for satellites launched after July of this year. See <a href="https://celestrak.org/NORAD/documentation/gp-data-formats.php">https://celestrak.org/NORAD/documentation/gp-data-formats.php</a> for details. These data are presently considered in beta test for the next two months while hosted on the test server <a href="http://newark192.amsat.org">newark192.amsat.org</a>, and we are very open to community feedback at webmaster at <a href="http://amsat.org">amsat.org</a>. Testers may experience outages and errors while we make improvements. We intend to put this into production on our main web server in July as we expect that satellites launched after this summer will require one of the new formats to accommodate longer object numbers. AMSAT will continue to publish TLE bulletins for satellites launched before July 2026 indefinitely.

Each year the American Radio Relay League (ARRL) sponsors Field Day as a âpicnic, a campout, practice for emergencies, an informal contest and, most of all, FUN!â The event takes place during a 27-hour period on the fourth weekend of June. For 2026 the event takes place from 1800 UTC on Saturday June 27, 2026 through 2100 UTC on Sunday June 28, 2026. Those who set up prior to 1800 UTC on June 27 can operate only 24 hours. The Radio Amateur Satellite Corporation (AMSAT) promotes its own version of Field Day for operation via the amateur satellites, held concurrently with the ARRL event. This year should be as much fun as last year since we have more than 10 transponders and repeaters available. Users should check the AMSAT status page at <a href="http://www.amsat.org/status/">http://www.amsat.org/status/</a> and the pages at <a href="https://www.amsat.org/two-way-satellites/">https://www.amsat.org/two-way-satellites/</a> for what is available in the weeks leading up to field day. To reduce the amount of time to research each satellite, see the current FM satellite table at <a href="https://www.amsat.org/fm-satellite-frequency-summary/">https://www.amsat.org/fm-satellite-frequency-summary/</a> and the current linear satellite table at <a href="https://www.amsat.org/linear-satellite-frequency-summary/">https://www.amsat.org/linear-satellite-frequency-summary/</a> If you are considering ONLY the FM voice satellites, there are ISS, SO-50, AO-123, SO-125, and SONATE-2. It might be easier this year to make that one FM contact for the ARRL bonus points with so many FM birds. The congestion on FM LEO satellites is always so intense that we must continue to limit their use to one-QSO-per-FM-satellite. This includes the International Space Station. You will be allowed one QSO if the ISS is operating Voice. It was suggested during past field days that a control station be allowed to coordinate contacts on the FM satellites. There is nothing in the rules that would prohibit this. This is nothing more than a single station working multiple QSOâs. If a station were to act as a control station and give QSOâs to every other field day station, the control station would still only be allowed to turn in one QSO per FM satellite while the other station would be able to submit one QSO. The format for the message exchange on the ISS or other digital packet satellite is an unproto packet to the other station (3-way exchange required) with all the same information as normally exchanged for ARRL Field Day, e.g.: W6NWG de KK5DO 2A STX KK5DO de W6NWG QSL 5A SDG W6NWG de KK5DO QSL If you have worked the satellites on Field Day in recent years, you may have noticed a lot of good contacts can be made on some of the less-populated, low-earth-orbit satellites like AO-7, RS-44, AO-73, and JO-97. During Field Day the transponders come alive like 20 meters on a weekend. The good news is that the transponders on these satellites will support multiple simultaneous contacts. The bad news is that you canât use FM, just low duty-cycle modes like SSB and CW. The complete rules for AMSAT Field Day may be found at: <a href="https://www.amsat.org/field-day/">https://www.amsat.org/field-day/</a>.

The effort aims to create communication systems capable of handling intermittent, disrupted, or long-delay links ranging from terrestrial amateur radio networks to future cislunar communication systems. Project developers describe RADIANT as a stepping stone toward Earth-Moon networking experiments using technologies and operating practices accessible to the amateur radio community. The initiative is supported by AMSAT-UK, AMSAT-DL, and Goonhilly Earth Station, and is actively seeking collaborators. The project is built around NASA Glenn Research Centerâs High-rate Delay Tolerant Networking software, known as HDTN, which implements Bundle Protocol version 7 (BPv7). Rather than assuming a continuous network path between endpoints, DTN stores and forwards data bundles whenever communication opportunities become available. This approach allows communication systems to survive outages, long propagation delays, and interruptions that would break conventional internet-style connections. Project developers say these networking methods are essential for future deep-space operations where connectivity may be intermittent or unpredictable. RADIANT incorporates amateur radio techniques directly into its design. The protocol stack uses Licklider Transmission Protocol carried over KISS framing and conventional amateur radio hardware operating at 9600 baud G3RUH packet speeds. Callsigns are embedded into DTN Endpoint Identifiers to preserve amateur radio regulatory compliance while allowing efficient network routing. Current demonstrations include store-and-forward operation, systems designed for persistent storage through power interruptions, priority handling of traffic, and telemetry monitoring through HDTN interfaces. Â <img class="gmail-aligncenter gmail-size-large gmail-wp-image-64664" src="https://www.amsat.org/wordpress/wp-content/uploads/2026/05/Radiant_DTN_Project_Roadmap_Infographic-1024x683.jpg" alt="" width="1024" height="683">Â RADIANT project infographic illustrates DTN networking concepts from terrestrial amateur radio links to future cislunar communications. [Credit: RADIANT] Among the projectâs early accomplishments is a functioning three-node cislunar simulation capable of introducing realistic packet propagation delays. Developers report demonstrations simulating EarthâMoon delays of approximately 1.3 seconds and EarthâMars delays ranging from three to twelve minutes. Contact Graph Routing is used to calculate communication paths through relay nodes, demonstrating multi-hop relay in simulation similar to what future space networking architectures may require. The project deliberately avoids encryption and cryptographic methods to maintain compatibility with amateur radio regulations. Development is planned in phases beginning with terrestrial validation using readily available amateur radio equipment. Phase 1 testing currently uses Raspberry Pi systems, Mobilinkd TNC4 hardware, and Yaesu FT-817 radios to validate networking functions across ground-based links. Future plans include demonstrations through the QO-100 geostationary satellite, a CubeSat engineering model, and eventually an orbital Low Earth Orbit payload operating on amateur frequencies. Longer-term ambitions include experiments supporting amateur participation in cislunar communications, the region of space between Earth and the Moon. Project organizers emphasize that amateur operators possess unique experience relevant to difficult communications environments, including weak-signal work, scheduled links, and operation over challenging propagation paths. RADIANT developers are seeking participation from amateur radio clubs, universities, CubeSat teams, microwave experimenters, and packet radio operators interested in contributing to future testing and development. Users registering through the project website can also access additional information and requirements associated with each development phase.

The company had to step down from a launch attempt on the evening of May 21, due to a technical issue. Specifically, a hydraulic pin holding the spacecraftâs tower arm in place would not retract. But on May 22, nothing prevented SpaceX from launching the upgraded version of its spacecraft designed for journeys to the moon and Mars.Â <img class="gmail-aligncenter gmail-wp-image-64698" src="https://www.amsat.org/wordpress/wp-content/uploads/2026/05/SpaceXV3-1024x621.jpg" alt="" width="800" height="485"> SpaceX Starship V3 Launch (Credit: SpaceX) The launch vehicle ignited all 33 of its Super Heavy boosterâs new Raptor 3 engines and then lifted off at 22:30 UTC from Starbase, Texas. During ascent, one of the boosterâs engines shut down, but Starship continued its flight until it was time for the stages to separate. The booster was able to perform a directional flip maneuver, which the company wanted to test for future missions. However, it was unable to light all the engines needed to perform a successful boostback burn, the other maneuver necessary for the rocket to be able to travel back towards its landing site.Â It wasnât a loss, however: SpaceX had been catching Super Heavy boosters with its launch towerâs mechanical arms in previous flights, but it never intended to recover this one. Despite the engine failures, SpaceX chief Elon Musk congratulated his team âon an epic first Starship V3 launch and landing,â telling them they âscored a goal for humanity.â SpaceX managed to pull a largely successful test flight, just in time for its Initial Public Offering (IPO). The company just publicly filed its IPO paperwork with the Securities and Exchange Commission, and Reuters has reported that SpaceX shares are expected to start trading on June 12.

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<a href="https://www.amsat.org/keplerian-elements-resources/">Â https://www.amsat.org/keplerian-elements-resources/</a>. The following satellites have been removed from this weekâs AMSAT TLE distribution: <ul><li>SilverSat NORAD Cat ID 66909 Decayed from orbit on or about 23 April 2026</li><li>HYDRA-W NORAD Cat ID 63490 Decayed from orbit on or about 24 April 2026</li><li>HADES-ICM (SO-125) 63492 Decayed from orbit on or about 22 May 2026</li></ul> <h3>General Perturbations Data Support</h3> AMSAT is pleased to announce that modern forms of what are called General Perturbations data are being disseminated via modern formats including JSON, XML and KVN at <a href="https://newark192.amsat.org/gpdata/current/">https://newark192.amsat.org/gpdata/current/</a>. The reason this change is being made is that we are running out of 5-digit catalog numbers and the TLE format is not viable for satellites launched after July of this year. See <a href="https://celestrak.org/NORAD/documentation/gp-data-formats.php">https://celestrak.org/NORAD/documentation/gp-data-formats.php</a> for details. These data are presently considered in beta test for the next two months while hosted on the test server <a href="http://newark192.amsat.org">newark192.amsat.org</a>, and we are very open to community feedback at <a href="mailto:webmaster@amsat.org">webmaster@amsat.org</a>. Testers may experience outages and errors while we make improvements. We intend to put this into production on our main web server in July as we expect that satellites launched after this summer will require one of the new formats to accommodate longer object numbers. AMSAT will continue to publish TLE bulletins for satellites launched before July 2026 indefinitely.

Itâs an old problem that NASA recently hoped was resolved. In January, NASA said that after multiple inspections and sealant applications, the pressure inside this segment, known as the PrK module, had reached a âstable configuration.â The PrK module is essentially a transfer tunnel attached to the Zvezda Service Module on the Russian segment of the space station. Unfortunately, the leak returned three weeks ago after Russian cosmonauts unloaded cargo from the Progress 95 cargo spacecraft. Although there is no impact on astronauts aboard the station, nor any immediate concerns about the stationâs health, the returning leak issue raises new questions about the long-term viability of the ISS.

The photos are available at the main mission site: <a href="https://solarsystem.nasa.gov/psyche-raw-images/">https://solarsystem.nasa.gov/psyche-raw-images/</a>. After getting gravity assist from Mars, Psyche will resume using its solar-electric propulsion system to continue its journey. The spacecraft started its six-year trip to its namesake asteroid back in October 2023. During the flyby, it got closer to Mars than the planetâs own moons and passed within 2,800 miles of its surface at its closest approach. The spacecraft is expected to reach its destination in 2029, after which it will spend two years orbiting and observing the asteroid. 16 Psyche is the largest known metallic asteroid in our solar system, and scientists believe data from observing it could give us insight about the formation of our own planetâs core.
