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.

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.

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,

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.
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.

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.

For Mars_B4_Moon ...
First, thank you for the posts you have contributed in the current period ...
Second, regarding #8
You may have quoted someone in your text above the link to the story about the agreement between the US and Japan.
If you had composed the text yourself, I am sure you would have written it differently.
The chances that this person will be the first non-American on the Moon are slim to vanishing.
Unless Elon Musk pulls off a miracle, it is highly likely the first non-American on the Moon will be Chinese.
NASA is currently depending upon unreliable old-Space suppliers.
NASA **does** appear to be encouraging Elon and Jeff Bezos, but of the two, I think Elon is the most likely candidate to beat the Chinese to the Moon.

Japan's Moon Lander Made It Through Another Lunar Night

If Mars has humans one day living in colonies or Europa or Titan and the Moon they might write songs of 'Resilience' etc maybe something like “Made It Through the Rain” by Barry Manilow, “Don’t Stop” By Fleetwood Mac, “You're Only Human Second Wind” Billy Joel “Fighting My Way Back” Thin Lizzy “Born to Run” Bruce Springsteen “Under Pressure” Queen featuring David Bowie “I Will Survive” by Gloria Gaynor etc
I know we have two art music threads but I'm going to give it a song and I am ignorant of modern Asian pop or J-pop
so world tribute bands, global soft rock power ballads, south-west London musician and a 1984 American neo-noir film

iSpace and LeicesterU to develop Lunar Night Survival technologies
https://www.spacedaily.com/reports/ispa … y_999.html
ispace, inc. (ispace), a global lunar exploration company, and the University of Leicester, have agreed to collaborate on approaches to lunar night survivability for future ispace lunar lander and rover missions. The University and ispace have entered into a strategic consulting agreement to explore lunar night survivability utilizing Radioisotope Heater Units on the Series 3 lunar lander and rovers. The University was awarded funding under Phase I and Phase II of the UK International Bilateral Fund to create mission concepts leveraging the technology on future missions.
The conditions on the lunar surface are extremely harsh with temperatures falling to minus 170 degrees Celsius during the two-week long lunar nights, when sunlight does not warm the surface. To realize long-term missions, new technology and systems are required to survive the cryogenic environment of lunar night.
The Space Nuclear Power group at the University of Leicester has been developing radioisotope power systems for over a decade. These power systems use the heat generated from the decay of radioisotopes and can be used to provide heat to spacecraft, or converted to electricity to power key subsystems. The technology development has been funded by the European Space Agency (ESA) European Devices Using Radioisotope Energy (ENDURE) program, which has been heavily supported by the UK Space Agency.
Project lead Dr. Hannah Sargeant from the University of Leicester School of Physics and Astronomy and Space Park Leicester said: "The radioisotope power technology that has been developed at the University of Leicester, in conjunction with National Nuclear Laboratory, is performing extremely well in our ongoing testing campaigns. In this project, we will be working with ispace to investigate the feasibility of using radioisotope heater units to provide sufficient heat to spacecraft to endure the lunar night."
ispace is leveraging its global presence through its three business units in Japan, the U.S., and Luxembourg, for the simultaneous development of Mission 2, currently planned to be launched in 2024, led by its Japanese office, as well as Mission 3, currently planned to be launched in 2026 and led by its U.S. office, and Mission 6, which will utilize the Series 3 lander and is scheduled to be launched by 2027
