Japanese firms finish acquisition of Spaceflight

Japan’s Mitsui & Co., working in partnership with Yamasa Co. Ltd., has completed the acquisition of Seattle-based Spaceflight Inc. from its parent company, Spaceflight Industries.

Today’s announcement of the transaction’s completion follows up on February’s announcement of the sale for an undisclosed amount. Spaceflight Industries’ other subsidiary, BlackSky Global, isn’t part of the transaction and will continue to operate as a privately held company with offices in Seattle and Herndon, Va.

Spaceflight Industries also has a 50% share in LeoStella, a satellite manufacturing company based in Tukwila, Wash. The other half of that joint venture is owned by Thales Alenia Space, a French-Italian aerospace company.

Mitsui and Yamasa will similarly split ownership of Spaceflight Inc. as a 50-50 joint venture, operating independently with its headquarters remaining in Seattle.

The sale brings a parting of the ways for Spaceflight Inc., which focuses on arranging launch services for rideshare satellites; and BlackSky, which is building a satellite constellation for Earth observation and provides geospatial data analysis tools.

Asteroid probe carries samples back toward Earth

Japan’s Hayabusa 2 spacecraft and its science team bid a bittersweet farewell to the asteroid Ryugu, 180 million miles from Earth, and began the months-long return trip to Earth with a precious set of samples.

“This is an emotional moment!” the team tweeted on Nov. 12.

“It’s sad to say goodbye to Ryugu,” project manager Yuichi Tsuda said at the Japan Aerospace Exploration Agency’s command center. “Literally it has been at the center of our lives over the past one and a half years.”

The farewell isn’t finished quite yet, however. Over the next few days, Hayabusa 2’s camera will capture pictures of the half-mile-wide asteroid as it recedes into the background of space. Then the probe’s field of view will turn back toward Earth for the return journey.

Spaceflight helps out with shooting-star satellite

Seattle-based Spaceflight says it’s handling the pre-launch logistics for a Japanese satellite that’s designed to spray artificial shooting stars into the sky.

Tokyo-based ALE’s spacecraft is just one of seven satellites due to be sent into orbit from New Zealand as early as Nov. 25, aboard a Rocket Lab Electron launch vehicle.

It’ll be the 10th Electron launch, earning the nickname “Running Out of Fingers.” It’ll also be the first launch to test the guidance and navigation hardware as well as the sensors that Rocket Lab will eventually use to help make the Electron’s first stage recoverable.

No recovery will be attempted during this mission.

The shooting-star satellite, ALE-2, is already making headlines in New Zealand. It’s designed to release particles from its sun-synchronous orbit below the International Space Station’s altitude, according to a timed schedule. When the particles re-enter Earth’s atmosphere, they’re supposed to burn up and create the appearance of meteors as seen from the ground.

In addition to the entertainment factor, ALE says scientists participating in the Sky Canvas project will be able to study the path of the particles during re-entry. That could lead to more accurate predictions of the path of satellites during orbital decay, and perhaps contribute to studies of weather and climate change.

“This launch gets us much closer to realizing the world’s first man-made shooting star,” ALE’s CEO, Lena Okajima, said in a news release. “We really appreciate Spaceflight`s support and attention to our mission, and we’re honored to take this big step with them.”

Some observers say the Sky Canvas project will be a distraction for astronomers as well as an attraction for skywatchers. Similar examples include the “Humanity Star” disco-ball satellite that Rocket Lab launched in 2018, and SpaceX’s first batch of 60 Starlink satellites.

Japan joins the global gravitational wave hunt

Japan’s Kamioka Gravitational-Wave Detector, or KAGRA, is due to start teaming up with similar detectors in Washington state, Louisiana and Italy in December, boosting scientists’ ability to triangulate on the origins of cataclysmic cosmic events such as black hole smash-ups.

Representatives of KAGRA, the U.S.-based Laser Interferometer Gravitational-Wave Observatory (LIGO) and Europe’s Virgo detector signed a memorandum of agreement today in Toyama, Japan, to confirm their collaboration. The agreement includes plans for joint observations and data sharing.

“This is a great example of international scientific cooperation,” Caltech’s David Reitze, executive director of the LIGO Laboratory, said in a news release. “Having KAGRA join our network of gravitational-wave observatories will significantly enhance the science in the coming decade.”

Nobel-winning physicist Takaaki Kajita, principal investigator of the KAGRA project, said “we are looking forward to joining the network of gravitational-wave observations later this year.”

Watch a Japanese probe blast an asteroid

If there was ever any doubt that Japan’s Hayabusa 2 spacecraft was able to get access to samples from an asteroid called Ryugu last month, a video released today should put those doubts to rest.

The black-and-white video clip, shot by the probe’s CAM-H monitoring camera, shows the sampling horn being lowered to the sunlit surface. Hayabusa 2 creeps nearer and nearer to its shadow, and suddenly there’s a spray of debris as the probe fires a bullet made of tantalum and backs away.

“Rocks reaching sizes of several tens of centimeters in diameter were ejected,” the Hayabusa 2 team said today in a science status report. “Many chips of this released debris are flattened plate-shaped and appear to reach quite a high altitude.”

Hayabusa 2’s sampling horn is designed to capture some of that debris. “The potential for sample collection is high,” the team reported.

Japan’s ispace moon mission plans battery test

The Japanese moon venture known as ispace says it has recruited new corporate partners and struck a deal to put a commercial payload on its Hakuto-R lunar lander.

Ispace has arranged for two spacecraft to be launched to the moon, in 2020 and 2021, as secondary payloads on SpaceX rockets. Those will be rideshare missions similar to the SpaceX Falcon 9 launch that sent SpaceIL’s Israeli-made lander on its way to the moon tonight.

Like SpaceIL, ispace includes veterans of a team that competed in the now-defunct Google Lunar X Prize. Team Hakuto took its name from the Japanese word for “white rabbit.” The R in the name of ispace’s Hakuto-R lunar project stands for “reboot.”

Ispace says it’s raised nearly $95 million in funding to support the Hakuto-R campaign. The 2020 mission would put a probe in lunar orbit, and the 2021 mission would send a lander and rover spacecraft to the lunar surface.

In a news release issued today, ispace says Japan-based NGK Spark Plug Co. has agreed to be a corporate partner in the Hakuto-R program. Part of the partnership will involve developing a payload to test solid-state battery technology on the moon.

Japan’s Hayabusa 2 spacecraft successfully touched down today on asteroid Ryugu, more than 200 million miles from Earth, during an operation aimed at blasting away and collecting a sample from the space rock.

The 18-foot-wide spacecraft was programmed to extend a yard-long tube to touch the surface, shoot a bullet made of tantalum into the asteroid and collect the bits of rock and dust thrown up by the impact.

In a series of tweets, the mission management team said telemetry confirmed that the bullet was fired and that the spacecraft was heading back to its stationkeeping position, 12.4 miles (20 kilometers) above the asteroid.

“Based on this, we determined touchdown was successful!” the Hayabusa 2 team tweeted. “A detailed analysis will now be done.”

Russians reboot space station computer

A balky computer system is working again on the International Space Station, thanks to a reboot, the Russian space agency reported today.

“The system was tested for one and a half turns of the station’s flight around the Earth (about two hours),” Roscosmos said in an online update. “In fact, all systems tested out properly.”

The computer, one of three redundant systems, crashed earlier this week. The other two systems continued to operate normally, and operations on the orbital outpost were unaffected. Roscosmos said there was no need to replace the system that suffered the glitch.

Roscosmos didn’t go into detail about the cause of the computer crash.
