Russia’s Destruction of an Orbiting Satellite Raises Space Debris Concerns

Russia tested an anti-satellite weapon on November 15, destroying one of its own old and defunct satellites, Kosmos 1408. Launched in 1982, Kosmos 1408 was some 300 miles above Earth. Its destruction generated a debris field in Earth orbit that prompted the seven International Space Station crew members, including one Russian cosmonaut, to take cover in their crew capsules for several hours, in case they had to abandon the station. Occupants of the Chinese space station are reported to have taken similar action. The incident also has generated criticism from many corners and a grave discussion on the possible impact of any future such tests, by Russia or anyone else.

The danger of damage to the ISS or an orbiting satellite aside, tracking a debris field that could include thousands of pieces, in order to head off collisions, is a concern all its own. Very small debris in space is essentially impossible to track reliably, if at all. The incident also comes at a time when the number of spacecraft in Earth orbit continues to grow. AMSAT President Robert Bankston, KE4AL, said that Russia’s action will pose a threat to all activities in low Earth orbit for years to come, placing satellites and human spaceflight missions at risk.

“Space is already crowded, but now there are at least 1,500 trackable fragments and, possibly, hundreds of thousands of smaller yet still-threatening pieces of debris in low Earth orbit,” Bankston said. “While space stations have the capability to move out of the way, with sufficient notice, most satellites in low Earth orbit, including those designed, built, launched, and operated by AMSAT, do not. As such, they face greater risk of catastrophic destruction or degraded mission functionality, if struck by fragments from Russia’s destruction of Kosmos-1408.”

Bankston said AMSAT is closely monitoring the situation and hoping for the best.

NASA Chief Bill Nelson echoed Secretary of State Antony Blinken in expressing his own outrage at Russia’s action. “Their actions are reckless and dangerous threatening as well the Chinese space station at the taikonauts on board,” he said. “The [ISS] is passing through or near the cloud every 90 minutes, but the need to shelter for only the second and third passes of the event was based on a risk assessment made by the debris office and ballistics specialists at NASA’s Johnson Space Center in Houston,” Nelson explained.

FCC Commissioner Nathan Simington condemned the incident as “irresponsible” and noting that orbital debris fields pose a threat to hopes for the peaceful use of space and “make the work of using space complicated and difficult,” he said in a statement. “For decades to come, they stifle scientific research, inhibit communications, and pose threats to the lives of explorers. And in the here and now, they pose a great threat to [existing] satellites of all nations” deployed for peaceful purposes.

“No one owns space,” Simington said. “And no one should intentionally make it more difficult to use.”

The FCC’s orbital debris rules date back to 2004, when the FCC adopted requirements affecting not only Part 97 Amateur Service rules but Parts 5 (experimental) and 25 (communications satellites) The FCC has made it clear that orbital debris rules apply to amateur satellites, in general requiring submission of an orbital debris mitigation plan with each license application.  

AMSAT-NA Elects Officers, Discusses Ongoing and Future Satellite Projects

AMSAT-NA President Robert Bankston, KE4AL, told the 2021 AMSAT Dr. Tom Clark, K3IO, Memorial Space Symposium on October 30 that the organization is looking ahead to future satellite missions but will “go commercial” in order to keep enough satellites in space. Bankston, who was re-elected at a virtual Board meeting on October 29, said AMSAT is in solid financial position and donations are “healthy.” Bankston said membership numbers are holding strong, with more than 4,000 members in 76 countries, and that recent administrative modernization has reduced overhead costs by more than 30%.

Vice President-Development Frank Karnauskas, N1UW, noted that, despite AMSAT’s solid financial standing, additional funds are needed to design, build, and launch satellites. Consequently, AMSAT is ramping up its grant-writing efforts, applying for grants from philanthropic organizations and corporate sponsors.

Bankston said AMSAT’s strategic plan prioritizes putting satellites into high-Earth orbits. He also summarized the GOLF (Greater Orbit, Larger Footprint) initiative as part of its plan to reach higher orbits. AMSAT will not be giving up on low-Earth satellites (FM CubeSats), however. “FM satellites are very important and can serve as a stepping stone to more sophisticated spacecraft,” Bankston said. AO-91 and AO-92 are “living on borrowed time,” so new initiatives are in order.

Bankston said purchasing commercial satellites can shorten the development time. AMSAT plans to purchase a v/U 1U FM CubeSat, powered by four lithium-ion cells, but the Board said 90% of funding would have to be obtained from external sources. This would not be a permanent approach, however.

Bankston said the organization will be seeking additional volunteers to put its plans into action. “Any expansion of the strategic plan will need more volunteers,” Bankston said, adding that current volunteers “are pretty much at full bandwidth.”

Vice President-Engineering Jerry Buxton, N0JY, reviewed satellite projects in the pipeline. These include providing a linear transponder module to the University of Maine for its MESAT1, set to launch in 2022.

The GOLF-TEE (Technology Evaluation Environment) CubeSat is under construction and has been added to a launch manifest tentatively for summer of 2022. Supply chain issues are impacting construction. GOLF-1 is planned for delivery 1 year after the completion of GOLF-TEE.

Bankston mentioned new regulations that will govern satellite launches in the future. The Orbital Debris Assessment Regulations (ODAR) complicate the design and licensing of the GOLF 3U platforms, however.

A new AMSAT award program was announced to recognize the contribution of rover stations to the world of grid hunting. The award is called the Reverse VUCC Award — or VUCC/r. Earning it could be tough. Rather than contacting a set number of grids per band, the goal is to make contacts from a set number of grids per band. AMSAT took over the issuance of this award from the Central States VHF Society in September. The number of grids coincides with the ARRL award.

Also: As of November 1, FM contacts will no longer be accepted toward the Robert W. Barbee Jr., W4AMI Award. A consensus of AMSAT Board members expressed concern over the demands being placed on the limited availability of FM satellite repeaters. The Barbee Award requires the submission of 1,000 satellite contacts via OSCAR-6 or later satellites. Endorsements are available.

The AMSAT Board also heard reports from officers and representatives. The 2021 AMSAT Dr. Tom Clark, K3IO, Memorial Space Symposium and Annual General Meeting is available on AMSAT’s YouTube channel. 

Radio Amateur Finds Another “Zombie Satellite”

British Columbia radio amateur Scott Tilley, VE7TIL, has found another “zombie satellite,” as he calls them. This time, he tracked and identified radio signals from the experimental UHF military communication satellite LES-5. Tilley says he found the satellite in what he called a geostationary “graveyard” orbit after noting a modulated carrier on 236.7487 MHz.

“Most zombie satellites are satellites that are no longer under human control, or have failed to some degree,” Tilley told National Public Radio (NPR) earlier this month. It’s not clear whether LES-5 is still capable of receiving commands.

LES-5 was built by MIT’s Lincoln Laboratory and launched in 1967 as part of the military’s Tactical Satellite Communication Program. It was supposed to shut down in 1972, but it continues to operate as long as its solar panels are facing the sun. Tilley told NPR that he was inspired by a ham in Cornwall who, in 2016, found an earlier satellite — LES-1 — built by the same lab and launched in 1965. What intrigued Tilley about LES-5 was that it might be the oldest functioning geostationary satellite in space.

After British Columbia went on lockdown due to the COVID-19 pandemic, Tilley found himself with a lot of free time for such a search. He located LES-5 on March 24.

From his home in Roberts Creek, British Columbia, Tilley, an amateur astronomer, routinely scans the skies for radio signals from classified objects orbiting Earth. Since he started, he’s located dozens of secret or unlisted satellites.

In 2018, while hunting for an undisclosed US government spacecraft lost in a launch mishap, he spotted the signature of IMAGE (Imager for Magnetopause-to-Aurora Global Exploration), a NASA spacecraft believed to have died in December 2005. The discovery delighted space scientists. NASA and another ham in the UK confirmed his finding. Launched in 2000 on a mission to monitor space weather, IMAGE mapped plasma patterns around Earth.

Canadian Military to Launch 3-satellite System

Canadian military to launch 3-satellite system to track vessels.

Canada is preparing to launch a group of three satellites to track ships near the nation’s coast and also track vessels in parts of the world where Canada conducts military operations with allied nations, the Department of National Defense (DND) announced in a press release.

“This mission will carry a multi-mode synthetic aperture radar and an automatic identification system to enable enhanced ship tracking and provide greater awareness of Canada’s territories as well as other areas of interest around the world where DND and its allies operate,” the release said on Friday.

In addition to the upcoming satellite launch, Canada will invest $6.7 million in 12 research projects to develop new Earth-observation technologies that simplify and accelerate intelligence collection, the release said. With matching contributions from private industry, the research effort will total more than $13 million, the release said.

One of the 12 projects will attempt to develop an on-board video processing system on ships, which will be used together with space-based radar and ship detection sensors to enhance near-real-time vessel detection, tracking and identification, the release said.

Another project will develop a multi-satellite data classifier to better distinguish between ship and non-ship targets, such as icebergs, according to the release.
