AMSAT Ambassador Program Seeks Input During Hamvention 2025

The newly developing AMSAT Ambassador Program will be informally discussed by program coordinator Bo Lowrey, W4FCL, Director – AMSAT Ambassador Program, during the Dayton Hamvention 2025. He’s seeking input from attendees during the May 16-18, 2025 event as to ways AMSAT can support Ambassadors and their efforts to engage the public.

An educator, Bo seeks interested Radio Amateurs to educate other Amateur Radio operators and the general public about the importance of Amateur Radio in space and the progress being made in meeting AMSAT’s mission and vision.

Ideas are especially sought for new ways to assist educators as well as inform and educate young people in the rapidly growing community of “Makers.” This group enjoys using 3-D printers, laser cutters and other high-tech tools to build items, many of which include electronics such as small board computers and peripherals, similar to the tech used in AMSAT’s Cubesat Simulator (See https://cubesatsim.com/).

Google Map by Bo Lowrey shows locations of the 41 AMSAT Ambassadors throughout the U.S.

Current and new AMSAT Ambassadors looking toward the future may want to consider the “maker” community (creators, innovators, and Do-It-Yourself enthusiasts) as a target audience. This segment of the general population includes prime candidates for Amateur Radio licensing and operations.

The maker population segment is very large and worldwide. It includes people of all ages, some with varying degrees of skills in electricity and electronics. Many schools, colleges and universities and specialized “maker groups” abound.

AMSAT Ambassador Tom Scheussler, N5HYP exhibits annually at a youth space and science fair in the Dallas-Fort Worth area.

An excellent example of an independent organization that caters to the makers in the U.S. is the New England SCI-TECH center. It is a non-profit STEM education center and maker space dedicated to project-based, hands-on learning for youth and families. See: https://nescitech.org/. They host an Amateur Radio club and offer courses in cubesat subjects.

Various education and promotion tools for Ambassadors to use at in-person events are provided.These include: 3′ x 5′ fabric banner / flag for display table; presentation binder with illustrations and answers to frequently asked questions. These are used to attract and inform event attendees. Also, a personal name and callsign badge identifying an AMSAT Ambassador is provided. If the event is of a significant size, a door prize from AMSAT may be available for that purpose.

For online presentations AMSAT provides access to a growing repository of existing presentations. There is an online folder for each Ambassador to store content. Ambassadors also have access to the interactive video capabilities of the MS365 for video presentations to any size group.”

Bo will be available at Hamvention on Friday, May 16 and Saturday May 17. Interested in speaking with Bo? Come by the AMSAT booth in Bldg. 1. Interested Radio Amateurs may contact Bo before, during or after Hamvention 2025 at [email protected].

For additional information see AMSAT at Hamvention 2025: https://www.amsat.org/amsat-at-hamvention-2025/. For more information about the AMSAT Ambassador Program visit: https://www.amsat.org/ambassador/

The AMSAT Forum will be presented Saturday, May 17, from 1:35 p.m. to 3:10 p.m. EDT in Forum Room 2. Attendees are encouraged to arrive early for the ARISS (Amateur Radio on the International Space Station) Forum at 12:40 p.m. in the same room.

AMSAT-DL Presents Their Space Days Event in September, 2025

AMSAT-Deutschland e.V. and the Bochum Observatory have scheduled Bochum Space Days 2025 from September 19 to 21, 2025. The event will provide a varied and informative program aimed at AMSAT members and all space enthusiasts. Current developments and future prospects for national and international amateur radio satellites and other space projects will be presented. Lectures, presentations and discussions will provide participants with valuable insights into the latest technologies, missions and research projects in space travel, according to AMSAT-DL.

Bochum Observatory is a research institute in Bochum, Germany. The institution came into being through a private initiative. Its main areas of interest are in radio astronomy and environmental research.

The Space Days event begins on Friday with a general “come together” and end on Sunday with the General Assembly. The exact schedule and further plans will be posted on the website when they are available. Anyone interested in giving a presentation is welcome to contact Bochum Observatory via the AMSAT-DL website: https://amsat-dl.org/en/save-the-date-bochum-space-days-2025/.

According to AMSAT DL, “Work is continuing on the ground station for ERMINAZ and other projects at the observatory in Bochum. In addition to the well-known deep space activities of AMSAT-DL and Bochum Observatory with the 20-meter parabolic antenna, there is also a great need to receive and, if necessary, command small satellites, CubeSats and PocketQube satellites in LEO. A corresponding Mission Control Center is currently being set up. We have been operating the DK0SB SatNOGS station with omnidirectional antennas (Eggbeater) on VHF and UHF in the 2m and 70cm amateur radio satellite range for several years now. Also APT and LRPT weather image reception on 137 MHz using a dedicated antenna and the SatDump software.”

Changes to AMSAT-NA TLE Distribution for May 9

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.

ARISS Proposal Window Closes May 23, 2025

The Amateur Radio on the International Space Station (ARISS) Program is seeking formal and informal education institutions and organizations, individually or working together, to host an Amateur Radio contact with a crew member on board the ISS. ARISS anticipates that the contact would be held between January 1, 2026 and June 30, 2026. Crew scheduling and ISS orbits will determine the exact contact dates. To maximize these radio contact opportunities, ARISS is looking for organizations that will draw large numbers of participants and integrate the contact into a well-developed education plan.

 

The deadline to submit a proposal is May 23, 2025. Proposal information and more details such as expectations, proposal guidelines and the proposal form can be found at www.ariss.org.

The Opportunity

Crew members aboard the International Space Station will participate in scheduled Amateur Radio contacts. These radio contacts are approximately 10 minutes in length and allow students to interact with the astronauts through a question-and-answer session.

An ARISS contact is a voice-only communication opportunity via Amateur Radio between astronauts and cosmonauts aboard the space station and classrooms and communities. ARISS contacts afford education audiences the opportunity to learn firsthand from astronauts what it is like to live and work in space and to learn about space research conducted on the ISS. Students also will have an opportunity to learn about satellite communication, wireless technology, and radio science. Because of the nature of human spaceflight and the complexity of scheduling activities aboard the ISS, organizations must demonstrate flexibility to accommodate changes in dates and times of the radio contact.

Amateur Radio organizations around the world with the support of NASA and space agencies in Canada, Japan, Europe and Russia present educational organizations with this opportunity. The ham radio organizations’ volunteer efforts provide the equipment and operational support to enable communication between crew on the ISS and students around the world using Amateur Radio.

ARISS NEWS

ARISS is Celebrating 25 Years of Continuous Operations on ISS. The ARISS forum at the Dayton Hamvention will be on Saturday May 17 in Room 2 from 12:40-1:40 p.m. (right before the AMSAT forum in the same space). The focus for this forum will be to provide the audience a viewpoint of the breadth and depth of the ARISS contributions to the Fram2 mission, the first mission to include amateur radio in a Dragon capsule and the first human spaceflight amateur radio mission over the North and South poles. The ARISS team plans to convey how the work and lessons learned on Fram2 has helped to propel exciting and pioneering lifelong learning ARISS 2.0 initiatives that are underway for youth education, youth engagement and for the amateur radio community.

Amateurs and others around the world may listen in on contacts between amateurs operating in schools and allowing students to interact with astronauts and cosmonauts aboard the International Space Station. The downlink frequency on which to listen is 145.800 MHz worldwide.

Satellite Shorts From All Over

+ Along with the CubeSat Simulator, the AMSAT Youth Initiative is another of AMSAT’s efforts to bring students into the world of amateur satellites and radio. This year’s AMSAT Hamvention booth features the first of a series of online courses intended to generate that interest. The “Introduction to Satellite Meteorology” course provides students with the opportunity to learn the role that satellites play in the field of weather forecasting. Following the program’s theme, “Satellites in Space Help Us Lead Better Lives on Earth,” the course appeals to student’s inherent interest in earth sciences. As the courses progress, they are introduced to the concepts of radio communications and eventually amateur radio. The free courses are available directly to students and their families but teachers and youth leaders are also encouraged to use the courses as they see fit. Anyone interested in STEM education is encouraged to experience the online course firsthand is encouraged to visit AMSAT in the Maxim building, booth #1007. (ANS thanks AMSAT for the above information.)

+ The Trump administration’s preliminary 2026 budget proposes the biggest single-year cut to NASA funding in the agency’s 67-year history. The cuts are part of the White House’s broader government “skinny budget,” which aligns with Elon Musk’s DOGE wishlist. The NASA portion would gut the agency’s science programs, cancel the Gateway space station project and phase out the Space Launch System (SLS) rocket and Orion capsule after only three flights. Congress would have to approve the budget, so some or all of these cuts may change before the 2026 funding is approved. (ANS thanks engadget.com for the above information.)

+ Scott Kelly, who was the first American astronaut to spend almost a year in Earth orbit on board the International Space Station, stars in “Never Stop Dreaming,” a minute-long film made by Goodnites as part of its “Mission Dry” campaign. The video was released by the nighttime underwear brand on National Astronaut Day, May 5, which coincides with the event when NASA first learned that it needed absorbent undergarments for its crew members. “Man, I gotta pee,” Alan Shepard, America’s soon-to-be first man in space, radioed to the launch control room from atop his Redstone rocket on May 5, 1961. Astronauts are helping to destigmatize a common childhood experience by pointing out the similarities between what some kids wear to bed and what explorers wear into space.

+ The AMSAT website offers a comprehensive list of communications satellites and supporting details was updated on April 27,2025. This list is an excellent overview of FM Repeater, Linear Transponder, and Digital Satellites as well as Re-entered or Inoperative Satellites. Each listing includes a brief comment about links to details about each one. Also, there are frequency charts for each type of satellite. Access the information from the “Satellite Info” top level menu dropdown list which also includes many other related choices. Alternatively, go directly from this link: https://www.amsat.org/two-way-satellites/. (ANS thanks AMSAT for the above information.)

+ ARISS is planning a special get together for all the Fram2 “alumni” attending Hamvention. This includes the Fram2 youth, hams and ARISS volunteers. The special get together will be held in the Education mini-forum area located right behind the ARISS and YOTA booths in the Volta Building. Please stop by at 10 a.m. on Saturday May 17 for this special event. This will be an outstanding opportunity for all of the Fram2 participants and volunteers to meet face-to-face, share stories and gather lessons learned. (ANS thanks Frank Bauer, KA3HDO, ARISS-USA Executive Director, for the above information.)

+ The International Amateur Radio Union is considering restructuring by consolidating all three Regions. A Zoom meeting was conducted in English for Region 2 (North America) on May 7, 2025.

Amazon Kicks Off Kuiper Network with Ambitious First Satellite Launch

Amazon launched the first 27 satellites for its Kuiper broadband internet constellation on Monday, marking the start of its long-anticipated challenge to SpaceX’s Starlink network. The satellites lifted off aboard a United Launch Alliance (ULA) Atlas V rocket at 7 p.m. EDT (2300 UTC) from Cape Canaveral Space Force Station in Florida, after an initial launch attempt earlier this month was delayed by weather.

The launch is part of Amazon’s $10 billion Project Kuiper, which aims to deploy 3,236 satellites into low-Earth orbit to deliver global broadband service. Unveiled in 2019, the initiative targets consumers, businesses, and governments, a customer base already served by Starlink’s rapidly growing presence in the satellite internet market. The service is also being positioned as a vital solution for rural and underserved areas.

Amazon’s Kuiper program has experienced more than a year of delays, pushing the inaugural deployment well past its original target of early 2024. Under a Federal Communications Commission mandate, Amazon must launch half of its satellite constellation—1,618 satellites—by mid-2026. Analysts expect the company may need to seek an extension due to its late start.

All 27 satellites from Monday’s launch are functioning normally, according to Amazon CEO Andy Jassy, who confirmed the status on social media nearly seven hours after liftoff. The confirmation marks a key milestone in the project. Amazon expects to begin customer service later this year, assuming deployment and testing continue on schedule.

Amazon could launch up to five additional Kuiper missions in 2025, according to ULA CEO Tory Bruno. The company has indicated that initial service could begin with as few as 578 satellites, enabling limited coverage in northern and southern regions, with global service expanding as more satellites are deployed. Amazon’s experience in consumer products and cloud infrastructure is seen by executives as a potential advantage over competitors.

SpaceX, which has launched over 8,000 Starlink satellites since 2019, currently leads the market with more than 5 million users in 125 countries. Despite SpaceX’s head start, Amazon founder Jeff Bezos remains optimistic about Kuiper’s future. “There’s insatiable demand for internet,” Bezos said in January. “There’s room for lots of winners.”

Europe’s Vega C Rocket Launches Satellite to Map Forest Health

The European Space Agency (ESA) successfully launched its Biomass satellite aboard a Vega C rocket on April 29, advancing both Earth science research and Europe’s independent access to space. The launch took place at 5:15 a.m. Eastern Daylight Time (0915 UTC) from the Guiana Space Centre in French Guiana. The satellite separated from the rocket’s Avum upper stage nearly an hour later, entering a sun-synchronous orbit at an altitude of 666 kilometers.

Built by Airbus Defence and Space, the 1,250-kilogram Biomass satellite is part of ESA’s Earth Explorer program. Its central feature is a P-band synthetic aperture radar (SAR), designed to measure the amount of carbon stored in Earth’s forests by penetrating the tree canopy and mapping forest biomass. Simonetta Cheli, ESA’s director of Earth observation programs, likened the technology to “a medical scan of the forest” during a prelaunch briefing.

Biomass is designed for a 5.5-year mission. The first 18 months will focus on tomographic radar mapping of forest interiors, followed by four years of interferometric observations to track changes in forest height and biomass. Beyond forests, the satellite will also observe glaciers and deserts, using the radar’s ability to penetrate ice and sand. ESA plans to collaborate with NASA, sharing data with the forthcoming NISAR satellite, which operates a similar SAR system at higher frequencies.

The satellite’s radar system required new advancements in radio-frequency electronics due to the use of lower-frequency P-band waves. Airbus official Justin Byrne noted that engineers had to develop custom amplifiers and supporting electronics. The radar’s 12-meter deployable antenna, built by L3Harris, will begin unfolding a few days after launch in a process expected to take four days.

This mission marks Vega C’s second launch since returning to flight in December 2024, following a 2022 failure during the VV22 mission. ESA and Arianespace officials emphasized the extensive reviews and oversight applied to the rocket to ensure reliability. “We are scrutinizing, very closely, all of the launcher for any anomalies or weak points,” said Toni Tolker-Nielsen, ESA’s director of space transportation, who added that this level of review will continue through five launches.

With Vega C and the upcoming Ariane 6 both operational, European officials underscored the strategic significance of sovereign launch capability. Arianespace CEO David Cavaillolès highlighted the importance of ending reliance on foreign providers like SpaceX. Arianespace has conducted two launches so far in 2025 and plans six more by year’s end. Responsibility for Vega C operations will soon shift to Avio, the rocket’s manufacturer, with the transition described as proceeding smoothly.

Changes to AMSAT-NA TLE Distribution for May 2, 2025

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 US 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.

Many times a school may make a last minute decision to do a Livestream or run into a last minute glitch requiring a change of the URL but we at ARISS may not get the URL in time for publication. You can always check https://live.ariss.org/ to see if a school is Livestreaming.

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.

The packet system is also active (145.825 MHz up & down).

A special ARISS-Russia SSTV event is on the ISS schedule beginning May 5 at 12:00 UTC. This is a celebration commemorating a regional holiday.

Monitor 145.800 MHz for potential activity during passes. This will impact the availability of APRS digipeater.

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

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.

+ Firefly Aerospace’s Alpha rocket suffered a launch failure early Tuesday after lifting off from Vandenberg Space Force Base in California. Roughly two-and-a-half minutes into flight, the rocket’s first stage separated, but a bright white vapor cloud appeared—possibly an explosion—just before the upper stage ignited. Though the upper stage’s Lightning engine fired for more than six minutes, damage to its nozzle significantly reduced thrust, preventing the rocket from reaching orbital velocity. The mission, which was carrying Lockheed Martin’s LM-400 tech demo satellite, ended with the rocket and payload falling into the Pacific Ocean. This marks another setback for Alpha, which has now only achieved two fully successful missions out of six. Despite contract wins and plans for a more capable vehicle, Firefly must improve Alpha’s reliability to compete in the crowded small-to-medium launch market.

+ NOAA has announced that satellites NOAA 15, 18, and 19 will be reclassified as end-of-life effective June 16, 2025. These polar-orbiting weather satellites are widely used by amateur radio enthusiasts and RTL-SDR hobbyists to receive APT and HRPT imagery. The news was first reported by Carl Reinemann on the USradioguy.com blog, where he clarified that despite the end-of-life designation, transmissions will continue. NOAA has confirmed that signals will still be broadcast on a “data of opportunity” basis, meaning they are no longer intended for operational or safety-critical use but remain suitable for hobbyist reception. NOAA also stated that no ground intervention will be provided for future sensor or hardware failures. Should any critical malfunctions occur, the satellites may be decommissioned, as was nearly the case with NOAA 15’s scan motor, which previously failed and later resumed function under unclear circumstances. (ANS thanks RTL-SDR.com and USRadioguy.com for the above information)

+ A Soviet spacecraft originally intended for Venus, Cosmos 482, is expected to make an uncontrolled reentry into Earth’s atmosphere around May 9–10, after orbiting the planet for over 53 years. Launched in March 1972, the mission failed when the upper stage of its Soyuz booster cut off prematurely, stranding the Venus lander in Earth orbit. The descent module—designed to endure Venus’ harsh atmosphere—remains intact and may potentially survive Earth reentry due to its heavy thermal shielding. Satellite tracker Marco Langbroek has modeled its descent and predicts it could hit the ground or ocean at speeds exceeding 145 miles per hour. Although the risk to people or infrastructure is low, the lander’s size and mass make its reentry comparable to a small meteorite impact. Its fiery return is a rare and fascinating reminder of Cold War-era space exploration still orbiting above us. (ANS thanks Space.com for the above information)
