As Amazon gears up to build and launch thousands of satellites for its Project Kuiper constellation, it’s talking up the space-based broadband network’s potential to enable new options for managing data traffic with Amazon Web Services — including private connectivity services that never touch the public internet.

Amazon also announced that Japan’s Nippon Telegraph and Telephone Corp., NTT Docomo and SKY Perfect JSAT have formed a strategic collaboration with Project Kuiper to bring advanced satellite connectivity options to their customers. NTT and SKY Perfect JSAT plan to distribute Kuiper services to enterprises and government organizations in Japan, while NTT Group companies will use Project Kuiper to boost wireless broadband connectivity for customers.

NTT and its associated companies, along with SKY Perfect JSAT, join Verizon and Vodafone as telecom partners for Amazon’s Project Kuiper, which aims to provide broadband data services to tens of millions of people around the world who are currently underserved.

Such partners are expected to be among the first beta testers for Project Kuiper’s network in the second half of 2024. Two weeks ago, Amazon said that two prototype satellites achieved a “100% success rate” in a series of orbital tests, opening the way for mass production to begin next month at a factory in Kirkland, Wash.

Project Kuiper is far behind SpaceX’s Starlink satellite network, which already has more than 2 million subscribers. Starlink’s satellites are built in Redmond, Wash., not far from Project Kuiper’s HQ. To catch up with Starlink, Amazon plans to leverage synergies with AWS as well as the company’s other lines of business, including Prime Video and online retail sales.

A lunar lander built and operated by ispace, a Japanese startup, descended to the surface of the moon today after a months-long journey — but went out of contact and was presumed lost.

“We have to assume that we could not complete the landing on the lunar surface,” ispace CEO Takeshi Hakamada said during a webcast of the Hakuto-R mission’s final stages.

Ground controllers at the Hakuto-R Mission Control Center in Tokyo continued trying to re-establish communications nevertheless, and Hakamada said his company would try again.

“We are very proud of the fact that we have achieved many things during this Mission 1,” he said. “We will keep going. Never quit the lunar quest.”

A Japanese company has put out the call for passengers who’d be willing to pay more than $175,000 for an hours-long ride in a balloon-borne capsule that will rise as high as 15 miles (25 kilometers).

Technically, that’s nowhere near the boundary of outer space, but it’s high enough to get an astronaut’s-eye view of the curving Earth beneath a black sky.

“It’s safe, economical and gentle for people,” the CEO of a startup called Iwaya Giken, Keisuke Iwaya, told reporters in Tokyo. “The idea is to make space tourism for everyone.”

Other companies are planning similar stratospheric tourist ventures. But if Iwaya’s venture sticks to its announced timeline and begins flying customers around the end of this year, it would be the first to get to market.

Japan’s Hayabusa 2 probe zoomed past Earth today and dropped off a capsule containing bits of an asteroid, finishing a six-year round trip.

But the mission is far from over: While Hayabusa 2’s parachute-equipped sample capsule descended to the Australian Outback, its mothership set a new course for an encounter with yet another asteroid in 2031.

Hayabusa 2’s prime objective was to deliver bits of Ryugu, an asteroid that’s currently 7.2 million miles from Earth. Mission controllers at the Japan Aerospace Exploration Agency, or JAXA, cheered and laughed when word came that the capsule had survived atmospheric re-entry.

Imagery captured by tracking cameras — and from the International Space Station — showed the capsule streaking like a fireball across the sky as it decelerated from an initial speed of more than 26,000 mph.

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.

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’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.”
