After almost four months of orbital maneuvers since its launch on September 7, 2023, Japan’s SLIM lunar lander entered lunar orbit today, with a targeted landing date of January 20, 2024.

The landing site is indicated by the map to the right near Shioli Crater. SLIM is mostly an engineering test mission, with its primary goal to test an autonomous unmanned landing system capable of putting a lander down within a small target zone of less than 300 feet across. It has some science instruments on board, but any data obtained from them will be an added bonus, since the lander is only designed to operate for about two weeks, during the first lunar day. It is not expected to survive the two-week long lunar night to follow.

Because of launch delays for both of the American landers, Intuitive Machine’s Nova-C and Astrobotic’s Peregrine, SLIM will make its attempt first.

JAXA identifies cause of Epsilon-S solid-fueled engine failure during test

9:23 am

Japan’s space agency JAXA has now identified the cause of the explosion that destroyed an Epsilon-S solid-fueled engine during a static fire test in July.

The explanation at the link is somewhat unclear, but the bottom line is that the failure was caused “by the melting and scattering of a metal part from the ignition device inside the engine.”

JAXA is working on a fix to prevent the part from melting, but the report provides no timeline on when the next Epsilon launch will occur. Nor do we know when Japan’s larger new rocket, the H3, will launch next as well, having failed during its first launch in the spring. At the moment, Japan is essentially out of the game.

Japan’s space agency JAXA was hacked this summer

10:12 am

According to officials of Japan’s space agency JAXA, its computer system was hacked this summer but only learned of that break-in recently.

The illegal access is believed to have occurred around summer, but JAXA was unaware of the attack until the police contacted the agency, according to the sources. A full investigation was launched after JAXA reported the cyber-attack to the Education, Culture, Sports, Science and Technology Ministry, which has jurisdiction over the agency.

Although no large-scale information leakage has been confirmed at this stage, an official related to JAXA said: “As long as the AD server was hacked, it was very likely that most of the information was visible. This is a very serious situation.”

Earlier hacks to JAXA’s systems have also occurred in 2016 and 2017, with the culprits identified as working under the direction of the Chinese military. It is very likely that China is involved this time as well. China has previously been identified as the perpetrator of hacks of JPL from 2009 to 2019, during which much of JPL’s files on its planetary missions was stolen. It was thus no surprise when later Chinese planetary missions looked like upgraded copycats of those missions.

Why China is attempting to steal anything from Japan’s space program is puzzling however, considering its recent failures. If anything, China’s space program is presently far more advanced than Japan’s, and it should be Japan trying to steal from China.

Japan to spend $6.6 billion over ten years to develop its space industry

9:19 am

The Japanese government has created a new $6.6 billion fund that it will provide to its space agency JAXA, spread out over the next ten years, to help develop the country’s commercial space industry.

The very short article at the link provides little additional information. For example, will JAXA be required to act merely as a customer, buying services from competing private companies, or will it be allowed to use this money to create its own projects that it designs, builds, and owns?

The difference is fundamental. Presently JAXA functions like NASA had for decades, partnering with only a handful of big space companies (Mitsubishi for example) to build its own government rockets and spaceships. The results have been comparable to NASA prior to 2010: Little gets built and whatever is built is overbudget and far behind schedule.

Since NASA accepted the idea of capitalism in space, where it no longer builds or owns much but relies on private enterprise to get it done, things have moved fast. Similarly, India and China have followed suit, and both are getting similar good results.

The unanswered question from this story is whether Japan has finally taken the leap to do it as well. Making this transition can be politically difficult, because the space agencies and big space contractors fight to protect their turf. It is not clear if the Japanese government is willing to fight that battle.

If it doesn’t, however, Japan will continue to be a backwater in space, like Russia,as the rest of the world’s space-faring nations increasingly turn to private enterprise, competition, and (most of all) freedom to get results.

Japan delays asteroid mission due to its rocket problems

9:02 am

Japan’s space agency JAXA has decided to delay its Destiny+ mission to the asteroid Phaethon until 2025 due to the continuing problems getting its Epsilon-S rocket off the ground.

Epsilon-S is intended as an upgrade to Japan’s Epsilon rocket, but its development has been plagued by failures. In October ’22 there was a launch failure of Epsilon, and in July ’23 the second-stage solid-fueled motor of Epsilon-S exploded during a test.

Phaethon is the parent asteroid of the Geminid meteor shower that occurs each year in December. According to the original plan Destiny+ would have done its fly-by of the asteroid in 2029. No new arrival date has been announced.

Japan awards Ispace $80 million to develop larger lunar lander

8:49 am

The Japanese government, not its space agency JAXA, today announced it has awarded the commercial company Ispace an $80 million grant to develop a larger lunar lander, following its failed attempt earlier this year to land its first Hakuto-R1 lander on the Moon.

Japan will provide a subsidy of up to 12 billion yen ($80 million) to moon exploration startup ispace (9348.T) as part of a grant programme for innovative ventures, industry minister Yasutoshi Nishimura said on Friday.

The new lander is targeting a 2027 launch, and according to the company’s own statement [pdf] will replace the Hakuto-R lander being used on its first two lunar missions, as well as the Apex lander the American division of Ispace is now building for NASA. It also appears that the contract is fixed price, and will only be paid out when the company achieves actual milestones of development.

In other words, the Japanese government is doing what NASA is now doing, moving away from a government model, where its space agency JAXA builds and controls everything, to a capitalism model, where it buys what it needs from the private sector. That JAXA did not issue this award demonstrates this transition, in that until now all such space contracts were through that agency solely.

Japan’s space agency JAXA studying new reusuable rocket concepts

9:50 am

Even as it struggles to complete the first launch of its H3 hydrogen-fueled expendable rocket, Japan’s space agency JAXA has begun study work on new reusuable rocket concepts, working with its long-time rocket partner Mitsubishi.

Few details were released, but it appears they are studying a replacement for the H3, possibly using methane fuel rather than hydrogen (which is very difficult and expensive to handle), that would be ready for launch in the 2030s.

Meanwhile, the H3 remains grounded after its March 2023 launch failure, when its upper stage engine failed to ignite. No new launch date has been set. Because Japan has no more H2A rockets left, and its smaller Epsilon rocket is also grounded due to launch and test problems, JAXA right now has no capability to launch anything.

Japan’s policy towards space was changed this year to encourage the development of independent, privately owned rockets, but this transition from government-run to commercial has barely begun, and might not go anywhere based on this new study. It appears both JAXA and Mitsubishi are fighting to hold onto their turf.

SLIM leaves Earth orbit and is on its way to the Moon

8:51 am

SLIM's planned route to the Moon

The Japanese lunar lander SLIM fired its engines on September 30, 2023 to begin its journey to the Moon. The map to the right indicates the planned route after this trans-lunar injection burn, first flying past the Moon to put it on a trajectory that will bring it back to the Moon at the proper speed and direction for its landing several months hence.

The main goal of this mission is engineering, to test the ability of an autonomous unmanned spacecraft to land precisely within a small target zone about 300 feet across. If proven, this ability will make it possible to send unmanned landers to many places that are presently impossible due to their rough topography.

The route that SLIM is taking to the Moon is also unusual, and is probably also an engineering test of its own. Flybys of planets to change a spacecraft’s path is not a new technique, but in the past it has been used to slingshot the probe to another object, not send it back to that planet.

Sierra Space raises another $290 million in private investment capital

2:26 pm

Sierra Space today announced that during its most recent funding round it successfully raised another $290 million in private investment capital, bringing the total capital it has raised to $1.7 billion.

The round is co-led by Japan’s largest bank, MUFG, Kanematsu Corporation, a Japanese trading company and Tokio Marine & Nichido Fire Insurance, Japan’s largest property and casualty insurance group with participation from Sierra Space’s existing investors. The companies are already participating in a JAXA (Japanese Aerospace Exploration Agency) study to explore how to conduct activities in LEO as the ISS approaches the end of service.

These Japanese partnerships act to strengthen Sierra’s already strong links to Japan, including ongoing negotiations to land its Dream Chaser reusable mini-shuttes at Oita Airport, as well as partnership deals with Kanematsu, Japan Airlines and Mitsubishi.

This successful fund-raising round suggests strongly that the company’s plans to finally have its first Dream Chaser cargo shuttle, Tenacity, ready to fly in December might actually happen. Or at least, that plan acted to convince these investors to pony up some cash.

Japan reworking law that limits its space agency from awarding contracts to private companies

8:32 am

The Japanese government is now in the process of reworking the law that governs its space agency JAXA, in that this law has up to now forbidden it from using any of its budget to directly fund the work of any private companies.

According to sources, the government plans to add a provision to the JAXA Law — the basis for establishing JAXA — to set up a fund to provide long-term, large-scale financial support to the private and academic sectors, and to submit a draft revision at an extraordinary Diet session this autumn.

In the past, JAXA has put money into two private companies out of its own income earned from intellectual property and other sources, and the investment per company was limited to several tens of millions of yen. In March, the Liberal Democratic Party proposed that a fund of ¥1 trillion be established over 10 years.

It appears this limitation might explain why Japan trails so badly in the aerospace sector. JAXA has been forbidden to award contracts to private companies. It has been required by law to do all the work itself.

I suspect one of the two private companies it has sent money to was Mitsubishi, which in turn been a major contractor in building JAXA’s H-2A and new H-3 rockets. The system however has not resulted in rockets that are competitive and inexpensive, which is why Japan has garnered little market share.

If the revision in the law allows JAXA to award development contracts to private companies as they develop their own rockets and spacecraft, owned not by JAXA but by them, then we may see a change.

JAXA schedules last H-2A rocket launch, carrying X-Ray telescope and lunar lander

9:06 am

SLIM's landing zone

Japan’s space agency JAXA today announced that it has finally rescheduled the launch of its XRISM X-Ray telescope and its SLIM lunar lander launch for September 7, 2023, lifting off using the last flight of its H-2A rocket.

The previous launch attempt several weeks ago was scrubbed due to high winds. This new launch date has a window of seven days, which means if weather scrubs the September 7th launch they will be able to try again immediately within that window.

The white dot on the map to the right shows the targeted landing site of SLIM, which is testing the ability of an unmanned probe to land precisely within a tiny zone of less than 300 feet across.

Meanwhile, with the retirement of the H-2A rocket and its replacement having not yet flown successfully (its first launch failed in March), Japan after this launch will be in the same boat as Europe, without a large rocket and lacking the ability to put large payloads into orbit.

Starlink makes deal with Japanese cell phone company

8:33 am

SpaceX has now partnered with the Japanese cell phone company KDDI to provide satellite-to-cellular service in remote areas of Japan that do not have good cell tower service.

The companies plan to start with SMS text services as early as 2024 and will eventually provide voice and data services. Almost all existing smartphones on KDDI network will be compatible with this new service as it employs the device’s existing radio services.

Since Starlink now has more than 5,000 satellites in orbit, it can offer its services to a wider ranger of customers worldwide, and has been slowly signing them up, from country to country.

JAXA scrubs launch of X-Ray telescope & SLIM lunar lander due to high winds

8:57 am

SLIM's landing zone
Click for interactive map.

Because of high winds, Japan’s space agency JAXA yesterday scrubbed the last launch of its H2A rocket, carrying the XRISM X-Ray telescope and the SLIM lunar lander.

A nice description of both payloads can be found here. XRISM is a simplified reflight of the Hitomi X-Ray telescope that failed immediately after launch in 2016.

Though SLIM carries a camera and two secondary payloads, both designed to hop along on the surface and obtain some data, its main mission is engineering, testing whether a robotic spacecraft can achieve a precision landing with a target zone of 100 meters, or 310 feet. The map to the right shows SLIM’s landing site, with the white dot in the close-up inset a rough approximation of that entire target zone. If successful this technology will make it possible to put unmanned planetary probes in places previously thought too dangerous or rough.

All three craft are designed to operate for only about fourteen days, during the daylight hours of the 28-Earth-day-long lunar day.

Japanese startup signs deal to provide its smallsat thrusters to South Korean university

9:20 am

Pale Blue, a Japanese startup which focuses on building water-vapor thrusters for cubesats, has signed a deal with Yonsei University in South Korea to provide that school smallsat thrusters for the satellites built by its students.

“Our mission aims for demonstrating cutting-edge laser communication, orbital maneuvering and formation-keeping,” Sang-Young Park, a Yonsei University astronomy professor, said in a statement. “These thrusters perfectly meet our requirements and offer the advantage of being not only environmentally friendly, but also free from regulatory constraints.”

Pale Blue proved its Resistojet thruster in orbit for the first time in March on a Sony Corp. Star Sphere satellite. Pale Blue plans to establish mass production of Resistojet thrusters to reduce the cost and lead time for potential customers in the United States, Europe and Asia, said Yuichi Nakagawa, Pale Blue co-founder and chief technology officer.

The company is also developing both an ion and hybrid thruster for satellites, and is another example of how the lowering of launch costs has encouraged the arrival of many new space companies doing many different things.

Rocket Lab gets two-launch deal with Japanese satellite company

9:27 am

Rocket Lab today announced that it has signed a two-launch deal with the Japanese satellite company Synspective, bringing to six total the number of Synspective satellites its Electron rocket will place in orbit.

Rocket Lab has been launching for Synspective since 2020 when the Company deployed the first satellite in Synspective’s synthetic aperture radar (SAR) constellation, which is designed to deliver imagery that can detect millimetre-level changes to the Earth’s surface from space. Since that first mission, Rocket Lab has been the sole launch provider for Synspective’s StriX constellation to date, successfully deploying three StriX satellites across three dedicated Electron launches. Including the two new missions, Rocket Lab is now scheduled to launch three missions for Synspective beginning in late 2023 from Launch Complex 1 in New Zealand.

This deal illustrates Rocket Lab’s continuing strong position in the launch market, while simultaneously illustrating the lack of any Japanese presence. Japanese Synspective might prefer to work with a Japanese rocket, but none exists that can compete with Rocket Lab.

Solid-fueled second-stage motor for Japan’s new Epsilon-S rocket explodes during static fire test

9:10 am

A solid-fueled second stage of Japan’s upgraded Epsilon-S four-stage rocket exploded 57 seconds into a two minute static fire test today, likely preventing that rocket’s planned first launch this year.

Police received an emergency call shortly after 9 a.m. from a nearby resident reporting that she heard “a loud noise and saw smoke” rising from the Noshiro Rocket Testing Center.

JAXA said that an explosion occurred during a combustion test of the second-stage engine of the Epsilon S rocket, which is an improved model of the small solid-fuel Epsilon rocket, at the facility in the prefecture in the northeastern Tohoku region.

While explosions during static fire tests of liquid-fueled rockets occur periodically, for a solid-fueled motor to explode seems much rarer, and suggests the mix and placement of the solid-fuel within the stage did not occur properly.

This failure continues a string of failures within Japan’s government-run space program, including a failure during the first launch of its new large H3 liquid-fueled rocket earlier this year. At present Japan’s space agency JAXA has set August 26th for one of the last launches of the rocket the H3 is replacing, the H2A, carrying an X-ray space telescope and a small lunar lander. Though today’s failure involves very different technologies and should therefore not impact that launch, it is possible JAXA will stand down entirely to see if there was some systematic issue throughout its management. It sure appears there is.

Japan’s military tests using Starlink for communications

8:49 am

Japan’s Self-Defense Forces (SDF) have been testing since March the use of SpaceX’s Starlink constellation to augment that nation’s own geosynchronous communications satellites.

Japan’s Defense Ministry signed a contract with an agent that provides SpaceX’s services to equip units of the Air, Ground and Maritime SDF with Starlink antennas and other communication devices. The SDF has been using the service at about 10 locations, including bases and camps, to verify whether there are any operational issues.

The ministry currently has two of its own X-band communication satellites in geostationary orbit about 36,000 kilometers above Earth for SDF units to use. The Starlink deal marks the first time the SDF is using a private-sector satellite constellation in low orbit.

An agreement with another company that provides a similar service will be concluded during the current fiscal year. [emphasis mine]

The goal is to provide Japan redundant communications capabilities in case China or Russia — both of which have become more aggressive militarily in the past few years — attempt to take out its own satellites. The highlighted sentence strongly suggests a deal with OneWeb is also being negotiated.

Japanese government adopts revised space policy emphasizing defense

10:00 am

The Japanese government today announced a revision to its space policy, with the changes mostly focused on increasing that nation’s military surveillance and reconnaissance capabilities in space.

Though defense and security appeared to be the focus of the revision, there were hints this would be achieved through a greater use of the competitive free market.

The government also vowed to bolster collaboration between the Defense Ministry and the Japan Aerospace Exploration Agency in a bid to provide support to private companies engaged in critical space technology development, the blueprint says. By attempting to stimulate private-sector-led development in space, the government will aim to reduce costs in the face of budget constraints, it adds.

Japan has traditionally operated as the U.S. used to, by letting its space agency JAXA do and control everything. JAXA in turn has routinely hired established companies like Mitsubishi to build what it wants, while retaining all control and ownership. The result has been a moribund effort, with Japan at present having no low cost rocket that can compete on the international market for business.

Whether this new policy will allow new companies to compete with the big established players remains unknown.

North Korea notifies Japan of orbital rocket launch; Japan and South Korea protest

8:56 am

North Korea today sent a notification to Japan’s coast guard announcing a May 31st to June 1st launch window for an orbital rocket launch aimed at placing a military reconnaissance satellite into orbit.

Japan’s coast guard said North Korean waterway authorities revealed that the launch window was between May 31 and June 11 and that the launch may affect waters in the Yellow Sea, East China Sea and east of the Philippines’ Luzon Island.

A safety warning was issued by Japan’s coast guard for ships in the area on those dates due to the possible dangers of falling debris. The coast guard coordinates and distributes maritime safety information in East Asia, which is most likely why it received North Korea’s notice.

For North Korea to launch a satellite into space, it would need to use long-range missile technology banned by U.N. Security Council resolutions. The country’s previous launches of Earth observation satellites were viewed as missile tests in disguise.

Both Japan and South Korea have protested, saying this launch would violate UN sanctions, with one Japanese official claiming that country would shoot it down if it crossed over its territory.

It is unknown if Japan has the military capability to shoot down a rocket in flight. It has never tested such technology. North Korea meanwhile has done numerous suborbital missile tests in the last two years, and has three times in the past launched small satellites into orbit, the last time in 2016.

Hakuto-R1 now scheduled to land on Moon on April 25th

9:41 am

Lunar map showing Hakuto-R1's landing spot
Hakuto-R1’s planned landing site is in Atlas Crater.

The private company Ispace yesterday announced that their Hakuto-R1 lunar lander, presently in orbit around the Moon, will attempt a landing on April 25, 2023, landing in Atlas Crater.

At approximately 15:40 on April 25, 2023, (UTC), the lander is scheduled to begin the landing sequence from the 100 km altitude orbit. During the sequence, the lander will perform a braking burn, firing its main propulsion system to decelerate from orbit. Utilizing a series of pre-set commands, the lander will adjust its attitude and reduce velocity in order to make a soft landing on the lunar surface. The process will take approximately one hour.

Should conditions change, there are three alternative landing sites and depending on the site, the landing date may change. Alternative landing dates, depending on the operational status, are April 26, May 1, and May 3, 2023.

The lander carries several commercial payloads, including the United Arab Emirates (UAE) Rashid rover. Ispace says the landing will be publicly live streamed, with more details to follow.

The company has from the beginning been treating this entire mission as an engineering test, with ten major goals, all related to proving out the lander’s systems. It has now completed eight of those goals, with a successful landing and successful operations on the surface the last challenges. If Hakuto-R1 succeeds, Ispace will become the first private company to complete a privately funded planetary mission to the Moon.

Furthermore, the company is already planning its second lunar landing mission, Hakuto-R2 in 2024, and a third more ambitious lunar mission for NASA, partnering with the American company Draper.

Japanese businesses face major losses due to Virgin Orbit bankruptcy

9:58 am

Two Japanese companies (one partnering with a Japanese airport) now face major financial losses due to the bankruptcy of Virgin Orbit.

Two Japanese companies, ANA Holdings … and little-known Japanese satellite development start-up iQPS Inc emerged among the top six creditors when Virgin Orbit filed for Chapter 11 bankruptcy protection on Tuesday.

ANA, owed $1.65 million, had been a key partner for the Oita spaceport, entering a provisional deal with Virgin Orbit in 2021 for 20 flights of its LauncherOne rocket there. ANA said it was hopeful Virgin Orbit, which has said it is seeking a buyer, would be able to restructure and resume business.

Fukuoka-based iQPS had paid a $5.2 million deposit to launch its small, lightweight constellation satellites weighing under 100 kilograms (220 pounds), representing a major portion of the $17.2 million Series A funding it had raised in 2017.

ANA and the government of Oita prefecture had also hoped to garner some economic benefits from tourism by making this deal with Virgin Orbit. That won’t be happening now, though the expectation by this Japanese local government was never realistic. In fact, it illustrates how divorced government officials are from economic reality. No airport spaceport is going to attract a lot of tourism, even if Virgin Orbit was prospering and launching monthly.

Japan officially delays next H2A rocket launch because of H3 launch failure

10:07 am

Japan’s space agency JAXA has now officially delayed its next H2A rocket launch, scheduled for May and carrying a Japanese lunar lander dubbed SLIM, because that rocket shares some components of Japan’s new H3 rocket, which failed during its inaugural launch in March.

No new launches are currently planned after a series of setbacks for the Japan Aerospace Exploration Agency, including the next-generation H3 rocket’s failure and that of the smaller Epsilon-6 in October, which was ordered to self-destruct after deviating from its intended trajectory shortly after takeoff.

The earliest the H2A launch can be rescheduled for is August, due to the orbital mechanics for getting it to the Moon. There are indications however that even this date will not be met.

H3 failure delays Japan’s entire space program

9:53 am

According to one official of Japan’s space agency JAXA, the failure of the first launch of its new H3 rocket in early March now threatens the schedule of much of Japan’s entire space program, even those missions being launched on the older H2A rocket.

The investigation into the launch failure, when the upper stage of the H3 rocket failed to ignite, remains unfinished with no word when it will be completed.

The H3 upper stage uses an engine designated LE-5B-3 developed by MHI [Mitsubishi Heavy Industries] and similar to the LE-5B engine used on the existing H-2A rocket. That is putting launches of the H-2A on hold while the investigation continues.

That may delay the upcoming launch of two science missions sharing an H-2A. The X-Ray Imaging and Spectroscopy Mission (XRISM), an X-ray astronomy spacecraft, and the Smart Lander for Investigating Moon (SLIM), a lunar lander, were scheduled to launch together as soon as May on an H-2A.

The article notes that XRISM replaces a 2016 Japanese X-ray telescope that failed immediately after launch. That failure then was bad, but just as bad is the seven years it has taken JAXA to have a replacement ready.

The H3 failure also threatens a JAXA Mars mission scheduled for launch in 2024, during the next launch window to Mars.

Japan’s space program more and more resembles Russia’s. It is controlled entirely by the government, which it appears does not allow competition within Japan, as all major rocket work is apparently confined to Mitsubishi. There have been unending quality control problems, within many probes as well as in the development of both the H3 and the Epsilon rockets. And the pace of operations is slow, much slower than other nations or companies.

It seems a major reform is needed, and it should start with Japanese government officials reading Capitalism in Space. They need to open up competition and release their space program from the control of JAXA, especially because JAXA is not doing a very good job. Like NASA, it would be better if JAXA stopped being a designer and builder, and become merely a customer obtaining products from many different competing private companies.

Hakuto-R1 snaps first picture of Moon from lunar orbit

9:18 am

Hakuto-R1's first released image from lunar orbit
Click for original image.

The science team for Ispace’s Hakuto-R1 privately-built lunar orbiter/lander earlier this week released the spacecraft’s first picture of the Moon since entering lunar orbit on March 20, 2023.

That image is to the right, cropped and reduced to post here. The photo resolution is quite good. It also demonstrates that the spacecraft’s attitude control systems for pointing the camera are working correctly.

Launched on December 11, 2022 by a Falcon 9 rocket, Hakuto-R1 will land in Atlas Crater on the northeast quadrant of the Moon’s visible hemisphere sometime in April, making it the first successful private commercial planetary lander to reach another world. If successful, it will then release the United Arab Emirates Rashid rover, that nation’s first planetary lander but its second planetary mission, following the Mars orbiter, Al-Amal, now circling Mars.

Japan’s new H3 rocket’s second stage fails during first launch

7:10 pm

Japan’s new H3 rocket failed today on its first launch when something went wrong at second stage ignition, after separation from first stage.

Once controllers realized the rocket would not reach orbit, they initiated a self-destruct sequence, ending the mission.

This is very bad news for Japan’s space effort. Right now it does not have a viable competitive commercial rocket industry. All rocket construction is supervised and controlled by its space agency JAXA, which almost exclusively uses Mitsubishi to build what it wants. With the H3 failing (built by Mitsubishi) and the H2A and H2B (both also built by Mitsubishi) slated for retirement, JAXA does not have a rocket it can use for future missions.

JAXA reschedules first H3 rocket launch following investigation

8:39 am

Japan’s space agency JAXA has rescheduled its second attempt to launch its new H3 rocket for March 6, 2023, following the completion of its investigation into the launch abort at T-0 on February 16, 2023.

As a result of the investigation, it is estimated that the first-stage flight controller malfunctioned due to transient fluctuations in the communication and power lines that occurred during electrical separation between the rocket and the ground facilities.

As a result, the solid rocket strap-on boosters did not ignite as planned, and the rocket’s computer, sensing this anomaly, shut down its main engines. The press release says they are installing “countermeasures” but provides no other information.

Japanese startup enters the high altitude balloon space tourism business

9:35 am

A Japanese startup, Iwaya Giken, announced yesterday that it is building a two-person capsule that will carry two persons, a pilot and passenger, on high-altitude stratospheric tourist balloon flights for about $180K per ticket.

The company, Iwaya Giken, based in Sapporo in northern Japan, has been working on the project since 2012 and says it has developed an airtight two-seat cabin and a balloon capable of rising up to an altitude of 25 kilometers (15 miles), where the curve of the Earth can be clearly viewed. While passengers won’t be in outer space — the balloon only goes up to roughly the middle of the stratosphere — they’ll be higher than a jet plane flies and have an unobstructed view of outer space.

The company teamed up with major Japanese travel agency JTB Corp., which announced plans to collaborate on the project when the company is ready for a commercial trip. Initially, a flight would cost about 24 million yen ($180,000), but Iwaya said he aims to eventually bring it down to several million yen (tens of thousands of dollars).

No date for the first launch was mentioned. This company now joins two American balloon companies as well as a Spanish balloon company, all planning to offer rides to the edge of space.

First launch of Japan’s H3 rocket aborts at T-0

8:25 pm

In its first attempt to launch its new H3 rocket today the rocket’s main liquid-fueled engines ignited, but then the two strap-on solid rockets failed to ignite at T-0, causing that main engine to shut down to protect the rocket and payload.

I have embedded the live stream below, cued to about T-39. At the end of the broadcast the rocket appeared in good condition, though it was still unclear what the caused the problem.

At the moment there is no word when JAXA, Japan’s space agency, will attempt another launch. The H3 is years behind schedule, and was developed in the hope it would be more efficient and cost less to launch than the H2A rocket Japan presently uses.

Japan’s H3 rocket’s first launch delayed due to problem in “flight system”

9:24 am

Japan’s space agency JAXA announced today that it will delay the first launch of its new H3 rocket for two days, to February 15, 2023, in order to fix an unidentified problem in the rocket’s “flight system.”

The H3 rocket’s first launch is already three years behind schedule. In 2022 the launch was delayed for a full year due to the discovery of defects in its main engines.

This government-controlled rocket was supposed to allow Japan to compete in the international launch market. It does not appear at this point that it will be able to do a very good job at that task. Though Mitsubishi is the main contractor, it appears JAXA is in charge and owns it. Such arrangements rarely produce a cheap, efficient, and reliable product for the commercial market.
