Japan cosmic cleanup firm is part of space arms race

(MENAFN- Asia Times)

TOKYO – Astroscale, Japan's space debris removal company, claims to have carried out“the world's first commercial mission to prove the core technologies necessary for space debris docking and removal.”

Comprising two satellites tied together – one designed to remove debris from orbit and one to simulate a piece of debris – it was launched from the Baikonur Cosmodrome in Kazakhstan in March 2021. The“test capture” demonstration was completed in August 2021.

And now the company has been awarded the 2021 Satellite technology of the Year Award for that“End-of-Life Services by Astroscale – demonstration” (ELSA-d) mission. The award was presented at the SATELLITE 2022 Conference and Exhibition, which was held March 21-24 in Washington, DC. The mission name refers to the end of the usable life of a satellite.

On March 19, it was announced that Seita Iizuka, the ELSA-d project manager, had received the Minister of State for Space Policy Award sponsored by the Cabinet Office, Government of Japan. Before joining Astroscale, Iizuka oversaw ground station operations at the Japan Aerospace Exploration Agency (JAXA).

According to Astroscale, the commercial satellite that follows the demonstration, called ELSA-M (M for“Multi”),“will be capable of capturing multiple defunct satellites in a single mission. Technology development and planning are well underway to test the servicer's multi-capture capability to provide debris removal solutions for constellation operators such as OneWeb.”

One Web is a global communications network with a fleet of 648 low-Earth-orbit satellites that are intended to provide high-speed, low latency, broadband internet services around the world when it is completed this year. It's headquartered in London and has a joint venture with Airbus to build its satellites.

But is Astroscale really the first commercial space debris removal company? That may depend on how you define commercial. Paul Kallender, a senior researcher at the Keio Research Institute, Shonan Fujisawa Campus, suggests that the hype overstates the case.

Kallender, who has been researching and writing about Japan's space program for the last 25 years, points out that the country's history of pursuing and acquiring objects in space goes back to the late 1990s.

The ETS-7 (Engineering Test Satellite No. 7), also called KIKU-7, which was equipped with a robotic arm, was launched by Japan's National Space Development Agency (NASDA, the precursor of JAXA) in November 1997.

As now noted on JAXA's website, KIKU-7 was“developed to acquire the basic technologies of rendezvous docking and space robotics which are essential to future space activities.”

That was not a commercial project, but it bears a strong resemblance to Astroscale's ELSA-d, doesn't it? This is because, in Kallender's words, Astroscale has been“piggybacking off old NASDA technology paid for by the Japanese taxpayer 25 years ago.”

ELSA-d used a magnetic docking mechanism, but Astroscale announced on April 4 of this year that it

In other words, a new robotic arm should outperform the company's magnetic docking mechanism.

Astroscale is not without state-supported competition in the race for firsts in the general field. On February 26, 2020, the New York Times reported:

On April 12, 2021, that company itself announced that

Northrup Grumman is also developing a Mission Robotic Vehicle (MRV), about which it says:“With two long-reaching robotic arms created by DARPA [the Defense Advanced Research Projects Agency of the US Department of Defense], the MRV will inspect, repair and augment satellites.”

Why would DARPA get involved?

On January 26, 2022, Breaking Defense writer Theresa Hitchens reported that“China's SJ-21 satellite now 'appears to be functioning as a space tug,' pulling a dead CompassG2, or Beidou, navigation satellite out of the way of other satellites operating in the heavily populated Geosynchronous Orbit, according to a new analysis by commercial space monitoring firm ExoAnalytic Solutions.”

This builds, according to Gunter's Space Page, on AOLONG-1,“an active space debris removal experiment launched by China's new generation CZ-7/YZ1A launch vehicle in 2016. The Aolong 1 payload was developed by CALT [China Academy of Launch Vehicle Technology] … to demonstrate the removal of a simulated space debris object by capturing the object and then bringing it to a re-entry trajectory to be burned up in the Earth atmosphere.”

Aolong means Roaming Dragon. As the Daily Beast put it in April 2017:“China just boosted a high-tech, mysterious new satellite into orbit. It might be a weapon. It might not be a weapon. There's no way to be certain, either way – and that's a problem for all spacefaring countries.”

Removing space debris or removing the reconnaissance and communications satellites of adversary nations, the technology required is the same.

Which brings us back to the question, What – and who – is Astroscale?

Astroscale's senior management reflects the company's close associations with the space and defense establishments of Japan, the US and the UK, and with international business and finance. Details from the company's website include:

• Nobu Okada, Astroscale's CEO, has also served as a member of the Subcommittee on Space Industry at the Cabinet Office of the Government of Japan and is a Fellow of the Royal Aeronautical Society of the UK. Inspired by his experience at a NASA camp for students when he was a teenager, Okada“used his personal funds as seed money and hired a team in Singapore in 2013 and opened an R&D office in Japan in 2015, a UK office in 2017, a US office in 2019, and an Israeli office in 2020, whilst raising US $300M capital. The team calls themselves 'Space Sweepers' and their mission is to reduce orbital debris and support long-term, sustainable use of space.”
• Chris Blackerby, chief operating officer,“served as the NASA Attaché for Asia, the senior space policy official in the US Embassy Tokyo, from 2012-2017.”
• Mike Lindsay, chief technology officer, was previously“director, spectrum architecture at OneWeb, where he oversaw mission design, systems engineering and spacecraft performance [and] held mission design and systems engineering roles at NASA and Google.”
• John Auburn, managing director, Astroscale Ltd, UK, previously worked as a flight dynamicist at the European Space Operations Center. He has also served as chairman of UKspace (the UK's industry trade association).
• Ron Lopez, president and managing director, Astroscale US Inc,“started his career as an intelligence officer in the United States Air Force, serving as the focal point for space situational awareness capability development at Air Force Space Command's Space Control Division.” He later worked at Boeing and“led the defense and space Asia Pacific sales team at Honeywell Aerospace.”
• Miki Ito, general manager, Japan, previously“worked as a researcher at NESTRA [Japan's Next-generation Space system Technology Research Association] where she participated in the HODOYOSHI-3 and HODOYOSHI-4 microsatellites projects developed with the University of Tokyo.

Obviously, there is no clear line separating civilian, government and military space technology, and there's plenty of career overlap.

Astroscale is also working with Mitsubishi Heavy Industries, Japan's top defense contractor and rocket maker,“on the technical aspects required to advance sustainable space operations [including] debris removal methods.”

I discussed this with space and defense expert Paul Kallender at a well-ventilated coffee shop in Tokyo:

According to DEWESoft, an engineering data company, there were about 4,550 active satellites in orbit around the earth as of September 1, 2021. Of these, 1,655 were owned by Elon Musk's SpaceX, 288 by OneWeb Satellites, 129 by the Chinese Ministry of National Defense, 125 by the Ministry of Defence of the Russian Federation, 87 by the US Air Force, 75 by Iridium Communications (a private company that serves the US Department of Defense), 63 by the US National Reconnaissance Office (an agency of the Department of Defense) and 60 by NASA. Most of the rest were owned by smaller countries and private interests.

In addition, there are about 3,000 inactive satellites in orbit around the earth, tens of thousands of pieces of debris large enough to be tracked and millions of fragments that are too small to be tracked but that could cause significant damage if they hit an active satellite.

There are also some potentially hostile satellites disguised as garbage trucks, and there are bound to be more.

As the NASA Headquarters Library says on its Space Debris page:“The space around our planet is filled with rubbish. It's time to take out the trash!”
