Japan Japanese Life Support Systems for Space Travel/Habitat

For SpaceNut .... there are several topics that include "Japan" but none seem to cover this work ...

Honda announced its plans to partner with the Japan Aerospace Exploration Agency (JAXA) for a joint feasibility study on a circulative renewable energy system.

While most car companies focus their efforts on creating a clean and renewable energy source for cars, SUVs, and trucks, Honda and JAXA look to pioneer a renewable energy system that can supply oxygen, hydrogen, and electricity for human outposts and rovers in space.

Both parties have signed a three-fiscal-year joint research agreement to pursue studies in achieving this goal. The results of Honda and JAXA’s combined research will be used on Lunar Orbital Platform-Gateway (Gateway) and on the surface of the moon.

“Based on the Japanese government's decision to participate in the Artemis program, JAXA has been working on mission development and system studies for realizing full-fledged lunar exploration. Oxygen, hydrogen, and electricity are essential to human activities in space. Realizing a circulative renewable energy system will enable us to obtain these requirements in space without relying on a resupply from Earth. This is expected to dramatically expand our activities in space. We would like to make steady progress in this study by leveraging the respective strengths of Honda and JAXA.,” said JAXA Vice President and Director General for Human Spaceflight Technology Directorate Sasaki Hiroshi.

In this joint project, Honda will be using its high differential pressure water electrolysis and fuel cell technologies. Through solar energy, it can electrolyze water which will then produce oxygen and hydrogen.

If there is anyone in the active membership who can explain how a "high differential" system differs from a "normal" system, I'd appreciate there contributing to this topic.

If there is someone in the forum readership NOT already a member, who might be able to assist with an explanation, please check the Recruiting topic for procedures.

Re: Japan Japanese Life Support Systems for Space Travel/Habitat

Could Japan keep the ISS flying?

Delta-v budget I will try link to vids from some old blogs that describe the needed boosts for the station, one video mentions a 2.7 meter per second increase in Delta-v from a US Commander of a previous Expedition, other videos in the wordpress blog were more 'fun' with Astronuas filming videos to illustrate the sensation felt by occupants of the ISS.

In Japan guys like Honda want a robot, Toyota build the futurist cars but Mitsubishi build their rocket ships?
Japanese HTV'craft has four 500-N-class main thrusters and twenty-eight 110-N-class attitude control thrusters. Both use bipropellant, namely monomethylhydrazine (MMH) as fuel and mixed oxides of nitrogen (MON3) as oxidizer.

Kounotori 9 aka HTV-9 was the 9th flight of the H-II Transfer Vehicle, a robotic cargo spacecraft to resupply the International Space Station

From an old wordpress entry, Reboost on the ISS occur every 3-6 weeks on average. https://jarphys.wordpress.com/2014/06/1 … -reboosts/

ISS can be rotated 180 degrees. Zvezda module has a Russian docking port where an ATV design and Progress design do their reboost, I believe the ATV has perhaps retired. Georges Lemaître ATV aka ATV-5 named after the Belgian astronomer Georges Lemaître, it was Deorbited in 15 February 2015,
http://www.n2yo.com/satellite/?s=40103
SpaceX in theory could reboost and do the role of Progress and boost the station,  Spacehab also released details about designs to deliver cargo to, and return cargo from, the International Space Station but the project was later shelved. Andrews Space was founded in 1999 by Jason Andrews and Marian Joh to be a catalyst in the commercialization, exploration and development of space. Originally named Andrews Space & Technolog was another offering commercial space cargo launches customers, the company became Spaceflight Systems, a subsidiary of Spaceflight Industries, Inc a lot of tech was bought by Japanese and old Japan family and companies such as Yamasa Company and Mitsui an interlocking groups of family and corporations and old money Lords and elite linked to Emperors that go back hundreds of years to the early Edo Shogun period largest keiretsu in Japan. Most economists with knowledge of Asia are aware of the keiretsu system through the Zaibatsu however after the War General Douglas MacArthur was partially successful in an attempt to dissolve the old elite family powers, industrialist family like Mitsubishi shipping company  formed under the uniting of old family industrial powers "mitsu"  the family characters use the old Chinese Japanese kanji 三 meaning "three" and "hishi" 菱, which becomes "bishi" ... Mitsu + Hishi ... under rendaku meaning "water caltrop", and "rhombus", they also embraced three oak leaves from the crest of the Yamauchi or Tosa family which is reflected in the company's logo. It's company logo is also translated as "three diamonds". Mitsubishi was an old collection of elite family united established in 1870, two years after the Meiji Restoration. I have a feeling some of the guys who build the JAXA H3 Launch Vehicle and Mitsubishi Heavy Industries who build the HTV unmanned resupply ship know everything Spaceflight Systems and SpaceHab were doing on their cargo design down to the smallest details, maybe one of the old Motor Industrial Companies can step up and give some new ISS designs.

Not sure but these old links might be useful

Re: Japan Japanese Life Support Systems for Space Travel/Habitat

I'm not sure if we have a dedicated thread on Japan's Moon Lander so I will leave the news here for now

For a while during the 80s and 1990s many news people thought Japan would take over everything, even as the bubble began to pop they still thought Japanese would take over the world and even today the Toyota continue with impressive Moon plans. Japan will probably one day have its cars on the Moon and not just Toyota, other auto mobile and motor manufacture companies join. Japan's new ambition has been an interesting development but Japan seems to be missing something over the years maybe a little 'luck' or consistency.

H-II Transfer Vehicle HTV, also called Kounotori is pressurized, you can live inside it an expendable, automated craft used to resupply the Japanese Experiment Module (JEM) and the International Space.  JAXA has agreed to provide an improved HTV-X logistic resupply flights to the Gateway mini-space station (launched by either Falcon Heavy or Ariane 6) as part of its Gateway contribution in addition to co-developing a habitation module with the ESA.

Hard landing: Japan firm fails in historic Moon bid
https://www.spacedaily.com/reports/Hard … d_999.html

Japanese start-up ispace conceded Wednesday its ambitious attempt to become the first private company to land on the Moon had failed but pledged to move ahead with new missions.

The unmanned Hakuto-R Mission 1 lander had been scheduled to arrive on the Moon's surface overnight but communications were lost during its descent and had still not been reestablished 25 minutes after the scheduled landing.

"It has been determined that there is a high probability that the lander eventually made a hard landing on the Moon's surface," ispace said in a statement.

The company said its engineers were working to establish why the landing had failed.

Japan likely to send first astronaut to moon under U.S.-led project
https://www.japantimes.co.jp/news/2023/ … n-project/

They have no independent manned flight but a lot of experience they have an Arm like Canada-Arm,  Japanese Experiment Module (JEM), nicknamed Kibo きぼう or Hope a Japanese science module for the International Space Station (ISS), have a Cargo ship the H-II Transfer Vehicle or HTV, also called Kounotori こうのとり "Oriental stork" or "white stork" an expendable, automated cargo spacecraft, they designed 'Artificial Gravity' module which never flew,  they had a Japanese Module, also known as the Kibo successor module, a commercial space module for scientific research being studied by the Japanese space agency JAXA, it is possible that design which never got to fly will become part of a commercial Axiom Station project or  Sierra Space's Orbital Reef space station, they have other smaller Centrifuge Artificial Gravity Experiments or Zero-Gravity Experiments for Centrifuge Development.
