MESAT1 Named a Finalist in Global Satellite Contest
MESAT1 (MO-122), Maine’s first research satellite developed by the University of Maine and with collaboration from AMSAT Engineering, was a finalist for the SmallSat “Rookie of the Year” Award, which is sponsored by the American Institute of Aeronautics and Astronautics.
The public was encouraged to cast their vote online to boost MESAT1 to victory as the top rookie small satellite mission. Voting was free and open to everyone through August 12. MESAT1 was among seven small satellites vying for the title.

Launched into orbit on July 4, 2024, MESAT1 was developed to get students involved in space science. The cost-effective nanosatellite, which measures 11.8 inches, is outfitted with four multispectral cameras that were designed to capture climate-related Earth imagery for experiments designed by Maine K-12 students. An AMSAT-provided LTM-1 linear transponder provides services to amateur radio enthusiasts around the world. In October of 2024, at the request of University of Maine, AMSAT designated MESAT1 as MESAT1-OSCAR 122 (MO-122).
“Access to space data motivates and excites students to learn fundamental skills in mathematics and science and helps them see the importance of STEM careers,” said UMaine Vice President for Research and Dean of the Graduate School Kody Varahramyan, who led the establishment of UMaine’s Space Initiative. “Being selected as a finalist for SmallSat Rookie of the Year is a national recognition of what Maine students and their faculty researchers can accomplish together.”
Finalists for the SmallSat award included teams from the University of Arizona, the University of Nebraska–Lincoln and international missions from Senegal and Croatia. MESAT1 stands out as a mission that empowered K–12 students from Falmouth High School, Fryeburg Academy and Saco Middle School to contribute to space exploration.
The winner, announced during the 39th Annual Small Satellite Conference from Aug. 10-13 in Salt Lake City, was CroCube the first Croatian satellite. CroCube also operates as an amateur radio satellite with a CW beacon and a GFSK9k6 – AX.25 G3RUH telemetry beacon at 436.775 MHz.
MESAT1 was designed, built and tested by students and faculty at UMaine in partnership with the University of Southern Maine, the Wells National Estuarine Research Reserve and AMSAT, the Radio Amateur Satellite Corporation, with support from NASA and the Maine Space Grant Consortium. The satellite’s development and integration for launch was led by Ali Abedi, who formerly served as associate vice president for research and a professor at UMaine.
This effort is part of the broader UMaine Space Initiative, which is working to develop a skilled space workforce and grow Maine’s presence in the space economy, including plans for a future Maine SpacePort Complex.
“This recognition puts Maine on the map as a state that not only builds satellites, but also builds opportunities — for students, teachers, researchers and entrepreneurs,” Varahramyan said.

AMSAT Organizations Continue to Challenge AST SpaceMobile Use of Ham Radio Spectrum
Facing more than 2,500 complaints from amateurs, AST SpaceMobile has responded by telling the FCC that it has designed its satellites to “mitigate interference” with amateur radio bands.
On August 5, the company replied to the U.S. Federal Communications Commission, defending its plan to use the 430 to 440MHz radio bands outside the U.S. to track and control its proposed fleet of 248 satellites. The company says it’s proposing “very limited, non-routine” use of the 430 to 440MHz bands and only for launch and early orbit phases for its satellites or “emergency operations when other frequency bands are unavailable.”
AST SpaceMobile’s attempt to justify its use of the amateur radio band for its satellites has done little to assuage concerns from the ham radio community.
“AST is again economical with the truth,” an amateur radio operator in Germany named Mario Lorenz wrote to the FCC on August 8.
The amateur radio community says AST is already using those bands. On August 8, AMSAT-Deutschland sent a letter to the FCC that says amateur radio users have detected signals from AST’s satellites over the radio bands.
“The claim is therefore either a misrepresentation or a deliberate falsehood,” AMSAT-Deutschland wrote. In particular, AST’s BlueWalker-3 satellite was spotted using the radio band up until July 23 as the amateur radio community began campaigning against the spectrum use.
“It also raises questions about AST’s technical maturity,” the group added. “Other large-scale satellite operators — such as SpaceX, with over 6,000 Starlink satellites in orbit — appear to manage TT&C (Telemetry, Tracking, and Command) functions without resorting to use of the amateur UHF band.”

NASA Satellite That Scientists and Farmers Rely On May Be Destroyed On Purpose
The Trump administration has asked NASA employees to draw up plans to end at least two major satellite missions, according to current and former NASA staffers. If the plans are carried out, one of the missions would be permanently terminated, because the satellite would burn up in the atmosphere.
The data the two missions collect is widely used, including by scientists, oil and gas companies and farmers who need detailed information about carbon dioxide and crop health. They are the only two federal satellite missions that were designed and built specifically to monitor planet-warming greenhouse gases.
It is unclear why the Trump administration seeks to end the missions. The equipment in space is state of the art and is expected to function for many more years, according to scientists who worked on the missions. An official review by NASA in 2023 found that “the data are of exceptionally high quality” and recommended continuing the mission for at least three years.
Both missions, known as the Orbiting Carbon Observatories, measure carbon dioxide and plant growth around the globe. They use identical measurement devices, but one device is attached to a stand-alone satellite while the other is attached to the International Space Station. The standalone satellite would burn up in the atmosphere if NASA pursued plans to terminate the mission.
Presidential budget proposals are wish lists that often bear little resemblance to final congressional budgets. The Orbiting Carbon Observatory missions have already received funding from Congress through the end of the 2025 fiscal year, which ends Sept. 30. Draft budgets that Congress is currently considering for next year keep NASA funding basically flat. But it’s not clear whether these specific missions will receive funding again, or if Congress will pass a budget before current funding expires on Sept. 30.
Last week, NASA announced it will consider proposals from private companies and universities that are willing to take on the cost of maintaining the device that is attached to the International Space Station, as well as another device that measures ozone in the atmosphere.
The missions are called Orbiting Carbon Observatories because they were originally designed to measure carbon dioxide in the atmosphere. But soon after they launched, scientists realized that they were also accidentally measuring plant growth on Earth.
Basically, when plants are growing, photosynthesis is happening in their cells. And that photosynthesis gives off a very specific wavelength of light. The OCO instruments in space measure that light all over the planet.
“NASA and others have turned this happy accident into an incredibly valuable set of maps of plant photosynthesis around the world,” explains Scott Denning, a longtime climate scientist at Colorado State University who worked on the OCO missions and is now retired. “Lo and behold, we also get these lovely, high resolution maps of plant growth,” he says. “And that’s useful to farmers, useful to rangeland and grazing and drought monitoring and forest mapping and all kinds of things, in addition to the CO2 measurements.”
The cost of maintaining the two OCO satellite missions up in space is a small fraction of the amount of money taxpayers already spent to design and launch the instruments. The two missions cost about $750 million to design, build and launch, according to David Crisp, a retired NASA scientist.
By comparison, maintaining both OCO missions in orbit costs about $15 million per year, Crisp says. That money covers the cost of downloading the data, maintaining a network of calibration sensors on the ground and making sure the stand-alone satellite isn’t hit by space debris, according to Crisp.
“Just from an economic standpoint, it makes no economic sense to terminate NASA missions that are returning incredibly valuable data,” Crisp says.

Changes to AMSAT-NA TLE Distribution for August 15
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/.
With HamTV becoming active on ISS, orbital elements are now updated twice daily in http://www.amsat.org/tle/ at 00:18 and 12:18 UTC. The intention is to have high quality TLE available to accurately calculate doppler shift for the 2.935 GHz downlink. Observations comparing these TLE to those that were caclulated based ephemerides and TLE produced by Johnson Space Center the last time HAMTV was active are desired, write jfitzgerald [at] amsat.org
Assignments to some of the Tevel2 satellites have been updated to match object numbers.
The following satellites have been removed from this week’s distribution:

+ The September 2025 issue of QST Magazine contains a review of the Halibut Electronics EggNOGS Antenna. The reviewer recommends this low-cost “eggbeater” antenna array primarily for receiving in unattended operations, such as weather satellite and SatNOGS ground stations. However, the kit has options for low power uplink transmissions, as well. The detailed review appears on pages 45-49 of the magazine, or see https://electronics.halibut.com/ for the manufacturer’s website. (ANS thanks QST Magazine for the above information.)
+ NASA Astronaut James A. Lovell (Captain, USN, Ret.), veteran of the Gemini VII, Gemini XII, and Apollo 8 missions before becoming the Mission Commander for the nearly disastrous Apollo 13 mission to the Moon, died August 7 at the age of 97. Lovell joined NASA in 1962 as part of its second group of astronauts. He was selected as backup commander to Neil Armstrong for the Apollo 11 lunar landing mission, and would have been the fifth human to walk on the moon, had it not been for the Apollo 13 “problem.” (ANS thanks NASA for the above information.)
+ SpaceX is now offering Starship flights to Mars, with Italy signing up as the first customer to send payloads. However, there is no announced start date for providing the service. (ANS thank The Orbital Index for the above information.)
+ Astronomers using the NASA/ESA/CSA James Webb Space Telescope have found strong evidence of a giant planet orbiting a star in the stellar system closest to our own Sun. At just four light-years away from Earth, the Alpha Centauri triple star system has long been a compelling target in the search for worlds beyond our solar system. If confirmed, the planet would be the closest to Earth that orbits in the habitable zone of a Sun-like star. However, because the planet candidate is a gas giant, scientists say it would not support life as we know it. (ANS thanks the European Space Agency for the above information.)
+ A newly released report states that in 2023, LIGO, the Laser Interferometer Gravitational-wave Observatory at CalTech, detected the most massive black hole merger yet, in which rapidly spinning black holes with masses of roughly 100 M☉ and 140 M☉ (M☉= 1 solar mass) merged to form a 225 M☉ black hole. Notice that 100 + 140 = 240 M☉, but the final object weighs a meager 225 Suns, meaning that 15 M☉ were converted directly into gravitational energy in this event, totaling 3 x 1048 Joules —- more energy than the combined stellar output of every star in the visible universe in that moment!
