A review of Japan’s effort to create a commercial space industry

9:54 am

Link here. The article does a nice job outlining the efforts of the new startups in Japan that have been successful in flying missions, such as the orbital tug company Astroscale and the lunar lander company Ispace, as well as newer companies such as Shachu, which proposes building and selling modules for use on any one of the new commercial space stations under construction.

The article also talks at length about Japan’s newly created ten year $6.5 billion strategic fund, designed to be provide funding for many different commercial projects and inspired by NASA recent switch from being the designer, builder, and owner of everything to simply a customer buying products from the private sector.

The fund has been given to Japan’s space agency to administer, and it remains unclear whether that government agency is prepared to give up power to the private sector as NASA has. This quote illustrates this uncertainty:

Since the effort is just starting, both companies and JAXA are uncertain how well the fund will work. Yasuo Ishii, senior vice president of JAXA, said the agency has assigned 450 people to administer the fund, including researchers and other experts. “We used to be an R&D institution and now we’re a funder,” he said.

He said JAXA will closely monitor progress on the initial awards made through the fund. “If some don’t go well, we may terminate them.”

It seems JAXA is so far using this fund to establish a large bureaucracy for itself, rather than issuing contracts to the private sector to build things JAXA needs.

We shall see how this plays out. The Japanese aerospace industry appears to be similar to the American space industry around 2008, with lots of old established big companies working hand-in-glove with the government space agency and a lot of small startups trying to establish themselves as competitors. In the U.S. at that time NASA was very resistant to give contracts to the startups. It took strong political pressure from within the upper levels of government, first in the Obama administration and then in the Trump administration, to force a change at NASA. Whether this will happen in Japan remains unknown.

Japanese company proposes building a module to add to Axiom’s space station

The Japanese company Mitsui has now proposed building a module — based on Japan’s HTV cargo freighter that did several missions to ISS — and sell it to the commercial space stations now under construction.

Mitsui has created a subsidiary called LEO Shachu to develop the module. What makes this project very likely to happen is that Mitsui is also an investor in Axiom’s space station, and according to the article at the link, a Axiom official who is also a retired Japanese astronaut who flew to ISS has expressed interest in it.

This story also helps outline the international landscape of the future stations. While Voyager Space’s Starlab station has been partnering extensively with Europe and Airbus, Axiom appears to be partnering more closely with NASA and Japan. The third station that has obtained NASA money, Blue Origin’s Orbit Reef, had made an earlier deal with Mitsubishi, but appears to have obtained few other outside partners, and that Mitsubishi deal only involved “development work,” not specific hardware. Moreover, Mitsubishi later made a new deal with the Starlab station, suggesting it had broken up with Blue Origin.

A fourth station, being built by the private company Vast with no NASA money, has partnered with SpaceX and ESA. It is also likely to be the first to launch its first module in August 2025, followed soon thereafter by a 30 day 4-person Dragon mission.

Astroscale’s ADRAS-J test spacecraft continues successfully maneuvers around abandoned rocket upper stage

The Japaneses orbital tug startup Astroscale has revealed that its ADRAS-J test spacecraft has successfully completed more complicated autonomous proximity maneuvers around an abandoned H2A rocket upper stage that it rendezvoused with in March 2024.

Astroscale announced July 9 that its Active Debris Removal by Astroscale-Japan (ADRAS-J) spacecraft conducted a “fly around” maneuver, going part way around the H-2A upper stage it has been inspecting for the last few months. ADRAS-J used sensors to maintain a distance of just 50 meters from the stage.

However, about one third of the way through the maneuver, ADRAS-J encountered what the company called an “unexpected attitude anomaly” that triggered an automatic abort. The spacecraft moved away from the stage as designed to avoid any risk of a collision. “The abort maneuver implemented during the fly-around operation demonstrated that ADRAS-J can maintain safety even while performing close approach observations of non-cooperative objects,” the company said in a statement, adding that engineers had found the cause of the anomaly and were preparing for another close approach to the stage.

The picture to the right is of that upper stage, taken shortly after ADRAS-J arrived near the stage in the spring. According to the company, the stage is in remarkably good condition despite fifteen years in orbit, and also is flying in a very stable manner, tumbling almost not at all. This data suggests a mission to grab it and de-orbit it safely would be relatively easy.

Japan dithers about capitalism in space

9:38 am

Despite its government creating in November 2023 a new “Space Strategic Fund” worth more than $6 billion designed to encourage capitalism in space and handing it to Japan’s space agency JAXA to administer, JAXA officials continue to dither on how to use that money to encourage private enterprise in space.

Japan’s space agency is seeking industry proposals for technologies that could contribute to future commercial space stations as the government studies what role it would play in supporting efforts to replace the International Space Station.

…That work will inform plans by Japan on how it can participate in commercial space stations being developed by American companies in partnership with NASA. “We are discussing how we will join NASA’s Commercial LEO Destination program,” said [Yasuo Ishii, senior vice president of JAXA]. “Our responsibility is not clear yet, but, of course, commitment at the government level is essential to commercial operations.” [emphasis mine]

The highlighted phrases above reveal the underlying motives of JAXA, which is not to encourage private independent space companies and reduce its involvement. Just the opposite. And it appears Japan’s government is a partner in this. While Japan gave that money to its space agency, which seems to be searching for ways to hold onto its power, both Europe and India instead quickly took power and funding away from their government agencies (Arianespace and ISRO respectively) to encourage independent private space companies to flourish.

This dithering will only put Japan further behind these countries as well as China, a reality that has become increasingly embarassing for the island nation.

Japan’s H3 rocket launches successfully for the second time

9:24 pm

Japan’s space agency JAXA today successfully completed the second successive launch of its new H3 rocket, placing an Earth observation satellite into orbit.

This was the third launch of the H3, with the first in May 2023 a failure, and the second a success in February 2024.

I have embedded the video of the launch below, cued to T-15 seconds. This was Japan’s third launch in 2024, exceeding last year’s total of two and matching its total from 2024.

The leader board for the 2024 launch race remains unchanged:

69 SpaceX
29 China
8 Russia
8 Rocket Lab

American private enterprise still leads the world combined in successful launches, 80 to 44, while SpaceX by itself still leads the entire world, including other American companies, 69 to 55.

Japanese government proposes 300-mile-long conveyor belt for moving packages

12:27 pm

Pork to the max! A supposedly “expert panel” in Japanese government’s Land, Infrastructure, Transport and Tourism Ministry has proposed building a 300-mile-long conveyor belt — possibly underground in a tunnel — between the cities of Tokyo and Osaka for moving packages, to be completed by 2034.

The biggest challenge is cost. According to a survey of construction companies, the cost of building an underground tunnel ranges from ¥7 billion to ¥80 billion per 10 kilometers, so a system linking Tokyo and Osaka would cost up to ¥3.7 trillion. When the ministry in the year 2000 first planned logistics links above ground, it estimated construction costs of ¥25.4 billion per 10 kilometers.

In dollars, the total cost of ¥3.7 trillion equals about $23 billion.

The so-called goal would be to eliminate 25,000 trucks, supposedly saving the world from those evil fossil fuels. That the belt would have to be powered of course is not mentioned, which I bet would probably require burning about the same amount of fuel.

The panel also claimed the conveyor belt would save money and reduce labor needs because it would also eliminate 25,000 truck drivers. With Japan facing a crash in population, the panel claims a shortage of labor is expected in the coming decades, and this plan will supposedly solve that. That’s also a fantasy. Who would upload the pallets onto the belt? Who would offload them? And how would those pallets be delivered at each point? And what about maintaining this giant conveyor belt? In the end, this plan will do nothing to reduce labor needs.

Nor is such a plan really necessary. When the population drops, the amount of cargo will drop as well. There will be no labor shortage in the shipping industry.

All this plan does is create a gigantic public works project that will almost certainly go over budget, fail to meet its schedule, and increase the cost of goods for both the companies and the public. But boy, it sure is going to employ a lot of government workers to supervise construction and operations!

Note I found about this project through a report at New Atlas, which as a left-leaning techno website accepted the plan instantly as brilliant and awe-inspiring.

Japan’s space agency reveals it was hacked in 2023

9:02 am

Japan’s space agency JAXA today revealed that beginning in 2023 and periodically into this year it has been attacked repeatedly by hackers, with data from more than 10,000 files stolen.

Attacks occurred in June 2023 and multiple times a year, although investigations are ongoing regarding whether more information was stolen in this year’s attacks.

In addition to internal data, potentially compromised entities include NASA, Toyota Motor Corp., Mitsubishi Heavy Industries Ltd. and the Defense Ministry, with which JAXA has nondisclosure agreements. Information from numerous aerospace and defense-related organizations and companies was also exposed.

JAXA stated that no sensitive information related to national security or rocket technologies was stolen in last year’s breach. Personal data of approximately 5,000 JAXA personnel and employees from partner companies was used to access the Microsoft 365 accounts of JAXA executives.

It appears JAXA officials only found out about the attack when police told them about it months after the June 2023 attack. Agency officials now say no sensitive rocket or satellite data was stolen. Instead, it appears the attack targeted personal communications as well as research facilities.

The report provided no indication about the source of these attacks, but noted that a 2016 attack is known to have come from China.

Engineers lose contact with Japan’s Akatsuki Venus orbiter

9:11 am

According to a terse announcement by Japan’s space agency JAXA on May 29, 2024, engineers from its Institute of Space and Astronautical Science (ISAS) have lost contact with Japan’s Akatsuki Venus orbiter.

ISAS has lost contact with Akatsuki after an operation in late April due to an extended period of low attitude stability control mode, and is currently making efforts to reestablish communication with the spacecraft.

Akatsuki has had a spotty and complex life. It was launched in 2010, but failed to enter Venus orbit as planned in two attempts in 2010 and 2011 because of a failure in its main engine. Engineers then improvised and — after orbiting the Sun for several years — were able to get it into Venus orbit in 2015 using only its attitude thrusters. Its primary mission ended in 2018, but it continued to study Venus’ atmosphere since.

Assuming Akatsuki is not recovered, as of now there are no operating orbiters at Venus. A mission by the private company Rocket Lab is expected to launch before the end of this year, followed by an orbiter from India in 2026. A NASA mission meanwhile is in limbo and will likely never fly, due to budget decisions at the agency, which took its funding and gave it to the troubled Mars Sample Return mission.

SLIM goes dark

9:14 am

SLIM's landing zone

The Japanese lunar lander SLIM has failed to respond to ground commands sent soon after dawn, ending the lander’s fourth night on the Moon.

SLIM was never expected to survive the harsh conditions of even a single 14-day-long lunar night after landing on the Moon in January 2024. Its primary mission had been to test precision autonomous landings, which it did successfully (though it landed on its side when one nozzle fell off just before touchdown). Yet, it then survived three lunar nights, resuming communications at dawn.

Its failure now is therefore no surprise, and actually marks a magnificent engineering success. The spacecraft’s hardware was proven robust enough to survive the very cold temperatures during lunar night, and suggests that future Japanese lunar landers using SLIM designs will function as well.

XRISM X-ray space telescope functioning despite closed “aperture door”

9:50 am

XRISM, a joint X-ray space telescope built by NASA and Japan’s space agency JAXA, is collecting data despite the failure on one instrument of an aperture door to open.

In January, project scientists said that XRISM was working well except for an aperture door, also called a gate valve, for the Dewar on its imaging instrument, Resolve, which failed to open. The instrument can still operate with the door closed, although the door, made of beryllium, does attenuate some X-rays at lower energies.

At the time, efforts were underway to try and open the gate valve. However, speaking at a May 7 meeting of the National Academies’ Board on Physics and Astronomy, Mark Clampin, director of NASA’s astrophysics division, said those efforts were on hold for the next year and a half.

Instead, the science team decided to proceed with science operations, since the telescope has two other working instruments, and can get data even from this hindered third.

XRISM is a replacement of a previous JAXA X-ray telescope that launched in 2016 but failed immediately.

Astroscale releases image of abandoned upper stage taken by its ADRAS-J orbital tug during rendezvous operations

10:37 am

abandoned upper stage, taken by ADRAS-J
Click for original image.

Capitalism in space: The Japanese orbital tug startup Astroscale today released an image its ADRAS-J spacecraft took of an abandoned rocket upper stage during rendezvous operations.

That image is to the right, cropped to post here. ADRAS-J’s mission is to test autonomous rendezvous and close proximity operations as well as obtain images of the stage in order to prepare for a second mission that will grab the abandoned stage with a robot arm and de-orbit it.

Both missions have been funded by Japan’s space agency JAXA. The mission however is unprecedented by that agency, in that it did not design the mission, but instead hired this private startup to do it, signaling that agency’s shift from being the designer, builder, and owner of such projects to becoming simply a customer. If successful, the mission will be the first to capture a very large piece of space junk and remove from orbit.

Astroscale wins contract to complete removal of large piece of space junk

8:39 am

Capitalism in space: Japan’s space agency JAXA has now awarded the orbital tug startup Astroscale a contract to complete the removal of an abandoned upper stage from a previously launched rocket.

Astroscale has already flown the first phase of this project, with its ADRAS-J tug flying in March and April a demo rendezvous mission with the rocket stage, getting to within several hundred meters of the stage. The second phase, now approved, will grab the stage with a robot arm and then de-orbit it. No date for the launch of that second phase was announced.

SLIM survives its third lunar night

9:07 am

Though it was primarily designed to prove its landing system and was never expected to resume operations after enduring the long 14-day-long lunar night, Japan’s SLIM lunar lander has successfully survived its third lunar night, resuming contact with Earth yesterday.

JAXA said on the social media platform X that SLIM’s key functions are still working despite repeated harsh cycles of temperature changes. The agency said it plans to closely monitor the lander’s deterioration.

While the newly downloaded data and photos have some scientific value, the important data is the spacecraft’s engineering status. Finding out what continues to work and what fails after each lunar night will inform engineers on what to do best to build future lunar landers and rovers.

Japan and NASA ink lunar deal

9:33 am

After several years of discussion, Japan and NASA have finally signed an lunar exploration agreement whereby Japan will build a pressurized rover that astronauts can use to travel large distances in exchange for NASA launching two Japanese astronauts to the Moon.

An enclosed and pressurized rover will enable astronauts to travel farther and conduct science in geographically diverse areas by serving as a mobile habitat and laboratory for the astronauts to live and work for extended periods of time. It will be able to accommodate two astronauts for up to 30 days as they traverse the area near the lunar South Pole. NASA currently plans to use the pressurized rover on Artemis VII and subsequent missions over an approximate 10-year lifespan.

This rover is being built in a deal between Japan’s space agency JAXA and Toyota. It will be very heavy, which meanst NASA is now planning its lunar exploration with Starship as a fundamental part. No other planned lunar lander could bring this kind of mass to the surface.

The two Japanese astronauts will likely fly on two different Artemis missions over that time-span. When these missions will occur will largely depend on how long NASA stubbornly sticks with is SLS/Orion/Lunar Gateway framework for getting astronauts to the Moon. These assets are not yet ready. They are also very cumbersome and expensive and slow. Missions using SLS expecially cannot occur faster than every two years, if that. If NASA depends on them, serious lunar exploration will likely not occur before 2030, at the earliest.

If however SpaceX’s Starship/Superheavy becomes operational in the next two years, and NASA switches operations to it instead, the pace will pick up, exponentially. Launches could likely occur multiple times per year, and it will be possible to put large amounts of mass on the Moon quickly. That lunar base will be built fast.

The decision to switch however will require a political decision, one that it appears many in Washington are reluctant to make. First, the Democrats now see Elon Musk as an enemy. Why award his company? Secondly, SLS/Orion/Gateway are great jobs programs. Abandoning them will eliminate a lot of wasteful pork, a sin to the politicos who operate our government for their interests, not the interests of the country.

Japan to sign deal with NASA to fly two Japanese astronauts to Moon

9:34 am

According to story in the Japanese press yesterday, a deal between Japan and NASA will be signed next week whereby Japan will have two astronauts go on Moon missions in exchange for providing cargo to the Lunar Gateway station as well as a manned lunar rover.

The report today is unclear whether those Japanese astronauts will land on the Moon, but I expect they will. The rover project is being led by Toyota. It will include a airtight cabin where spacesuits will not be necessary and passengers can also sleep, allowing for very long exploratory traverses from the landing site.

Reports of this deal have been appearing in the press since 2022, when NASA said it would involve flying one Japanese astronaut to the Moon. In December 2023 it was reported that the deal would be signed within a month. It is now April. It appears the extended negotiations have gotten Japan a second astronaut Moon walker.

NASA’s Artemis program is beginning to shape up as an international program for getting almost everyone to the Moon but Americans. I am exaggerating, but I think in the future Americans will find it easier to go on a private mission to the Moon than depend on NASA, especially because of all the international deals NASA will have to honor.

Japan awards development agreements with four rocket startups

1:14 pm

Capitalism in space: Japan’s space agency this week awarded development agreements to four Japanese rocket startups, signaling that nation’s attempt to shift from depending on JAXA’s government-built rockets to becoming a customer of an industry of competing commercial rocket companies.

Japan Aerospace Exploration Agency (JAXA) and Interstellar signed a basic agreement in March. Space One, whose Kairos solid rocket exploded seconds after liftoff earlier this month, was also selected under the JAXA-SMASH (JAXA-Small Satellite Rush Program) initiative. Two further companies also signed basic agreements. These are Space BD and Mitsui Bussan Aerospace, which offer services aimed at the commercial utilization of space.

The agreements mean the companies will have priority for future contracts. These are designed to support private-sector entities capable of launching satellites developed under JAXA’s small satellite missions and advance the commercialization of space transportation services.

These deals are part of a new policy announced in November that includes $6.6 billion to help encourage the growth of a Japanese commercial space sector, independent of that nation’s space agency.

It remains uncertain whether JAXA will let go the purse strings and actually allow these new companies ownership of what they do. The deals as described sound like the agency is using its power to attempt to capture the companies, rather than encourage their independent growth.

We shall have to wait and see. On its face this announcement is very good news for Japan’s space industry, as it suggests that things might be changing.

The investors behind Space One, the Japanese commercial rocket company that had a launch failure yesterday

9:01 am

The explosion yesterday of the new Japanese-built Kairos-1 solid-fueded rocket shortly after lift-off immediately raised questions whether the new rocket company that built it, Space One, could survive that failure.

This story from CNBC suggests it will, based mainly on the nature of its principal investors.

Space One was set up in 2018 by a consortium of Japanese companies including Canon Electronics, IHI Aerospace and construction firm Shimizu, along with the government-owned Development Bank of Japan. Mitsubishi UFJ and Mizuho Financial Group, two of Japan’s biggest banks, also own minority stakes in Space One.

The story is focused on the declines in the stock values of these companies, following the failure, with Canon’s stock falling the most, 12.7%.

My takeaways from the article however are different. First, these are not small investors. Space One is backed by some of Japan’s biggest corporations as well as indirectly by the Japanese government. One failure should not cause them to back out of the project.

Second, that the company was formed in 2018 by these Japanese heavy-hitters and only now was able to finally attempt a launch — that ended in failure — suggests Japan’s heavy-hitters continue to do things slowly and poorly. Not only have these big companies been working much too slow to build this relatively small rocket, Mitsubishi’s effort to build the much larger H3 rocket for Japan’s space agency JAXA has also been fraught with delays and problems, from engine cracks to launch failures. It appears Japan’s space industry is building things with the same lackadaisical attitude of America’s modern airline industry.

Third, that this “startup” was created by a team of old space large companies suggests Japan still doesn’t get the basics of capitalism. This new company isn’t creating any real competition. It was instead apparently formed to keep these heavy hitters in control of the Japanese launch market. This partnership reminds me of the many projects put together for decades by American consortiums of old space companies, such as Boeing teaming with Lockheed Martin to create ULA. All such partnerships were designed not to create new companies and new innovative products that would compete, but to maintain the control these old companies had on the industry.

Space One will likely fly again, but until we begin to see completely new companies from Japan, backed by independent new investors, this country is going to continue to lag behind everyone else.

First launch of Japanese rocket startup fails

10:03 pm

The first launch attempt by the Japanese rocket startup Space One failed today, when its Kairos-1 rocket blew up mere seconds after launch.

The launch took place from the company’s own launchpad in the south of Japan. The live stream shows the rocket appear to lift off cleanly, moving upward out of frame. When the video then switches camera to a more distant view, the rocket fails to appear from behind a nearby hill. Instead, a white cloud explodes upward. Shortly thereafter the live stream switches back to the launchpad, where there is a fire and smoke. Fire hoses then begin working to put the fire out.

Space One is the first independent commercial rocket startup in Japan apparently not working with that country’s JAXA space agency. We will have to wait and see whether it can recover from this failure.

Japanese rocket startup scrubs first launch attempt

9:11 am

The first Japanese rocket commercial rocket company, Space One, today scrubbed the first launch attempt of its Kairos rocket, scheduled to take off from its own launchpad in the south of Japan.

“We informed the public in advance that we wanted to make the area free of people, but even 10 minutes before the launch, a vessel remained in the area, so we decided to cancel the launch because it would have been impossible for them to leave promptly,” Space One executive Kozo Abe told a news conference in the afternoon.

Abe said there were no technical problems with the launch and that the next attempt could come as soon as Wednesday, with the company likely to give a more detailed schedule at least two days before the new date.

The rocket has four-stages, the first three solid-fueled and the last liquid-fueled. Its capacity is comparable to Rocket Lab’s Electron rocket, and the company hopes to eventually ramp up to as many as twenty launches per year.

SLIM put back to sleep for second lunar night

3:51 pm

Engineers at Japan’s space agency JAXA have put their SLIM lunar lander back to sleep on February 29, 2024 with the hope it might survive its second night on Moon.

“Although the probability of failure will increase due to repeated severe temperature cycles, SLIM plans to try operation again the next time the sun shines (in late March),” the update from JAXA read, automatically translated from Japanese to English by Google.

Like Intuitive Machines Odysseus lunar lander, SLIM’s overall mission was a success, as it proved it could land automatically within a very small target zone and do so softly enough that it could send back data to Earth. The failures and problems experienced by SLIM, such as having a nozzle fall off causing it land sideways are simply fixes that can be instituted on future missions.
