Physicists shrink their next big accelerator

9:52 am

Because of high costs and a refocus in research goals, physicists have reduced the size of their proposed next big particle accelerator, which they hope will be built in Japan.

On 7 November, the International Committee for Future Accelerators (ICFA), which oversees work on the ILC, endorsed halving the machine’s planned energy from 500 to 250 gigaelectronvolts (GeV), and shortening its proposed 33.5-kilometre-long tunnel by as much as 13 kilometres. The scaled-down version would have to forego some of its planned research such as studies of the ‘top’ flavour of quark, which is produced only at higher energies.

Instead, the collider would focus on studying the particle that endows all others with mass — the Higgs boson, which was detected in 2012 by the Large Hadron Collider (LHC) at CERN, Europe’s particle-physics lab near Geneva, Switzerland.

Part of the reason for these changes is that the Large Hadron Collider has not discovered any new particles, other than the Higgs Boson. The cost to discover any remaining theorized particles was judged as simply too high. Better to focus on studying the Higgs Boson itself.

Japanese metal manufacturer faked specifications to hundreds of companies

2:55 pm

Holy moly! Kobe Steel, a major Japanese supplier of steel and other metals worldwide, has admitted that it faked the specifications to metals shipped to hundreds of companies over the past decade.

Last week, Kobe Steel admitted that staff fudged reports on the strength and durability of products requested by its clients—including those from the airline industry, cars, space rockets, and Japan’s bullet trains. The company estimated that four percent of aluminum and copper products shipped from September 2016 to August 2017 were falsely labelled, Automotive News reported.

But on Friday, the company’s CEO, Hiroya Kawasaki, revealed the scandal has impacted about 500 companies—doubling the initial count—and now includes steel products, too. The practice of falsely labeling data to meet customer’s specifications could date back more than 10 years, according to the Financial Times.

For rockets the concern is less serious as they generally are not built for a long lifespan, but for airplanes and cars this news could be devastating, requiring major rebuilds on many operating vehicles.

Mitsubishi wins launch contract from Inmarsat

1:34 pm

Capitalism in space: Mitsubishi has been awarded a commercial launch contract from Inmarsat.

Recent Inmarsat satellites have launched on Proton, Falcon 9, and Ariane 5 rockets operated by International Launch Services, SpaceX and Arianespace. MHI [Mitsubishi Heavy Industries] has positioned the H-2A as a secondary player in the global launch market, and the Inmarsat 6 F1 contract gives the Japanese company its second commercial telecom launch deal after the Canadian-owned Telstar 12 Vantage satellite lifted off from Tanegashima in November 2015.

Japan has made noises about shifting control of its launch industry from its space agency JAXA to the private sector. This new contract between Mitsubishi and Inmarsat suggests that they are following through with that shift. However, though no specific price was mentioned in the article, the quote below indicates that Mitsubishi will have a big hill to climb to become competitive.

“The reason why we got the launch order from Inmarsat, I think, was not, of course, the cost-competitiveness of the H-2A launch vehicle, but I think our launch record is very good — 35 consecutive successes, high reliability — and another is on-time launch,” [Ko Ogasawara, Mitsubishi vice president] said in remarks last week at Euroconsult’s World Satellite Business Week conference in Paris. “We keep our schedule, and I think they put a high value on that.”

Mitsubishi’s next generation rocket, the H3, is being targeted for a launch price of $50 million, half of what the H-2A charges and more competitive in today’s market.

New Generation looks to establish private spaceport

8:39 am

Capitalism in space The new private partnership led by Canon, dubbed New Generation Small Rocket Development Planning, is now searching for a location to build its own private spaceport in order to bypass restrictions placed on launches at Japan’s two government launch sites.

While JAXA can launch at any time during the year, the deal with the local fishing council limits the number of launches per year to 17, and requires JAXA to coordinate its launches for the year with that council. For New Generation, which wants to compete in the smallsat rocket business and will thus likely need to launch dozens, if not hundreds, of times per year, this arrangement won’t work.

Akatsuki finds super-rotating equatorial jet on Venus

4:56 pm

Japan’s Venus orbiter Akatsuki has discovered a previously unseen equatorial jet with wind speeds that often exceed 200 miles per hour.

The winds, named “equatorial jet” by the research team, were found from July to August 2016 when an infrared camera captured images of areas about 45 to 60 kilometers above the planet’s surface. The areas are invisible at optical wavelengths due to extremely dense clouds of sulfuric acid. The camera spotted thick clouds traveling at a speed of 288 kph to 324 kph near the planet’s equator.

Based on the news reports, it appears the significance of this discovery is that they identified a particular jet stream at a specific latitude. Previous observations did not have that resolution.

This would have been posted in the morning, but the internet access here in this Torrey hotel is almost as slow as what I experienced in Glacier. I had it written, but I sinply couldn’t get it to post this morning.

Japan’s beginning shift to commercial space

9:08 am

Link here. The article provides a good sense of the state of Japan’s private space industry, which at this moment is generally restricted one company, Interstellar Technologies, and its as yet unsuccessful effort to launch a suborbital rocket. The following quote however helps explain why Japan has been unable to interest anyone in buying its H-2A rocket for commercial launches.

Launch costs associated with Japan’s main H-2A rocket are about ¥10 billion per launch (about $90 million), so miniature satellites often ride together with bigger satellites. A period of 50 days is required between launches, meaning the number of launches is low in Japan compared to countries including the United States, Europe, Russia, China and India. Large satellites are given priority in the launch schedule, so it is often difficult to choose a launch window for miniature satellites. [emphasis mine]

I think the $90 million price is a significant reduction from what JAXA used to charge. Fifty days to prep for launch however is ungodly slow.

New Japanese private joint venture to enter smallsat rocket industry

9:35 am

Capitalism in space: A Japanese private joint venture has formed with the intent to compete in the new smallsat rocket industry.

The new company is led by President Shinichiro Ota, a former industry ministry bureaucrat and once the head of the Japan Patent Office. NGSRDP will initially be based at Canon Electronics’ headquarters, studying technologies and costs with the hope of starting commercial operations as early as this year.

The joint venture has set a price point of 1 billion yen ($9.1 million) or less per launch — an amount seen as competitive against overseas rivals. At present, plans call for a rocket smaller than the Epsilon rocket currently under development by the Japan Aerospace Exploration Agency, or JAXA, but larger than JAXA’s SS-520 minirocket.

The four companies had been discussing formation of a small rocket company for about three years. President Ota has said that the “time is ripe” for the joint venture. IHI Aerospace has played a key role in the development of Epsilon, while Canon Electronics has been involved in the SS-520 project.

I would say that this is a clear sign that the competition in the smallsat rocket industry is definitely heating up.

Note that the name of this new joint venture, New Generation Small Rocket Development Planning (NGSRDP), is quite horrible. I hope they come up with something better soon for marketing purposes.

Japanese launch scrubbed due to problem with rocket

9:29 am

Japan’s space agency JAXA scrubbed a Saturday launch of a GPS satellite because of a possible leak in the H2-A rocket’s helium pressurization system.

The Japanese have not released much information. However, the problem might be more serious than normal, because the rocket was still on the launchpad on Sunday, almost a day after the launch itself was scrubbed. Normally when a launch is scrubbed they move quickly to safe the rocket and get it back into the assembly building to assess the issue. That the rocket was not moved suggests they might be having a problem doing this.

Japanese private rocket launch terminates early due of communication failure

9:14 am

Capitalism in space: The first launch of the first privately-built and funded Japanese suborbital rocket was terminated early today because of a communications failure.

The rocket’s developers, Interstellar Technologies, said they aborted the launch after about 80 seconds and it landed about 8 kilometers (5 miles) offshore. The aim had been to launch the rocket, called “Momo,” to an altitude of 100 kilometers (62 miles), but it only traveled about 30-40 kilometers (19-25 miles).

NASA and JAXA approve replacement of failed Japanese X-ray space telescope

10:39 am

NASA and JAXA have agreed to build a replacement for the Japanese Hitomi X-ray space telescope that failed after only a few weeks in orbit in March 2016.

The X-ray Astronomy Recovery Mission, or XARM, could launch as soon as March 2021, filling a potential gap in astronomers’ X-ray vision of the universe, according to the Japan Aerospace Exploration Agency, or JAXA. NASA has agreed to a junior partner in XARM — pronounced “charm” — and supply X-ray telescopes and a spectrometer instrument for the Japanese-led mission, according to Paul Hertz, directory of NASA’s astrophysics division.

ESA unveils dual orbiter mission to Mercury

10:31 am

After twenty years of development, the European Space Agency this week finally unveiled the completed dual orbiters that it hopes to launch on a seven year journey to Mercury in October 2018.

The 4,100-kilogram BepiColombo consists of two orbiters that will launch together — the ESA-managed Mercury Planetary Orbiter (MPO) and the JAXA-owned Mercury Magnetospheric Orbiter (MMO). The two spacecraft will be delivered to the orbit around Mercury stacked on top of each other by the Mercury Transfer Module (MTM). During the seven-year journey, the MMO will be shielded from the sun by the MMO Sunshield and Interface Structure (MOSIF), which will also serve as a mechanical and electrical interface between the two orbiters.

“MPO focuses on the planet, the surface and the interior size,” said Reininghous. “The orbit is a polar one — 480km times approximately 1500km — a little bit elliptical but extremely close to the planet as such with a return period of 2.3 hours. The data return is estimated at 1.5 gigabit per year.”

The MMO will focus on the planetary environment including the planet’s atmosphere, according to Reininghous. “The orbit is also polar but far more elliptical — 590 km times approximately 11,700 km. It has a period of 9.3 hours. The data return is approximately 10 percent of what we expect from the MPO.”

The European orbiter is much larger and more expensive, with Japanese probe budget being about a tenth the cost.

According to ESA, the mission took so long to build because in 2004, after about seven years of development, ESA suddenly realized that its orbiter’s thermal protection was inadequate, and required a complete redesign. To me, this is either outright incompetence (they knew from the start they were going to Mercury) or a clever way to extend the funding so that it provides an entire lifetime’s work for its builders. Think about it. Twenty-one years from concept to launch, then seven years to fly to Mercury, and then one to two years in orbit. That’s more than thirty years for this single mission.

Japan’s next rocket on schedule for 2020 launch

4:58 pm

A new Japanese rocket, the H3, being built by Mitsubishi and designed to cut launch costs by half, is presently on schedule for debut in 2020.

Key quote from the article:

JAXA has given MHI a greater level of influence on the H3 than it did with the H-2A. Ogasawara said whereas the total launch vehicle design for the H-2A was JAXA’s responsibility, MHI’s role as prime contractor and vehicle integrator gives the company more creative freedom. He stressed, however, that JAXA is still directly involved in the design and development for certain key components. “Therefore, we work together, JAXA and MHI, very closely,” he said.

I don’t know how much of that claim is true. That they are making it though suggests that they have been strongly influenced by the shift in the U.S. from NASA-run projects to commercially-run projects.

Japan begins testing new rocket engine

8:40 am

Capitalism in space: Japan has begun testing the rocket engine it will use in its next generation rocket.

The H-III will succeed the country’s current H-series rockets, H-IIA and H-IIB. The rocket will use commercially available components and a fuselage that can be mass produced, lowering launch costs to about half of the current price tag of approximately 10 billion yen ($88.6 million). The new, more powerful engine will allow the H-III to carry a midsize to large satellite weighing up to 6.5 tons — 60% more than the H-IIA.

If I understand this correctly, a launch with this new rocket will cost about $45 million, which will make it very competitive with SpaceX. At the same time, it is not as powerful, which means it will not serve the exact same customer base. Instead, its capacity makes it a direct competitor to India’s GSLV Mark III rocket.

Japan aims for record 8 launches in 2017

3:46 pm

Capitalism in space: If all goes as planned, Japan plans to launch a record of eight launches in a single year in 2017, partly because they will begin launch that nation’s own GPS satellite constellation.

Most of these satellites are government launches. Still, the number and in increase in launch pace indicates that Japan does not wish to be left behind in the increasing competition within the launch industry.
