Japanese Astronauts To Land On Moon As Part of New NASA Partnership

Under a new agreement between the U.S. and Japan, the first non-American on the Moon as part of the Artemis lunar exploration campaign will be a Japanese astronaut. SpaceNews reports: At an event in Washington, NASA Administrator Bill Nelson and Japanese Minister of Education, Culture, Sports, Science and Technology (MEXT) Masahito Moriyama signed an agreement regarding an additional Japanese contribution to Artemis, a pressurized lunar rover called Lunar Cruiser. NASA will deliver the rover to the moon, which the agencies said should take place ahead of the Artemis 7 mission scheduled for no earlier than 2031. NASA will also provide two seats on future Artemis lunar landing missions to astronauts from the Japanese space agency JAXA, the first agency other than NASA to secure spots on landing missions.

The Japanese rover will support extended expeditions from Artemis landing sites that are beyond the range of the Lunar Terrain Vehicle that three American companies are developing for NASA under contracts announced April 3. The rover is designed to accommodate two astronauts for up to 30 days, with an overall lifetime of 10 years. The announcement, though, offered no details about when the Japanese astronauts would fly to the moon. 'It depends,' Nelson said at an April 10 briefing when asked about schedules, noting that the two countries 'announced a shared goal for a Japanese national to land on the moon on a future NASA mission assuming benchmarks are achieved.'

'No mission has been currently assigned to a Japanese astronaut,' added Lara Kearney, manager of NASA's extravehicular activity and human surface mobility program, at the briefing. The implementing agreement (PDF) said several factors will go into crew assignments, including progress on the pressurized rover, or PR: 'The timing of the flight opportunities will be determined by NASA in line with existing flight manifesting and crew assignment processes and will take into account program progress and constraints, MEXT's request for the earliest possible assignment of the Japanese astronauts to lunar surface missions, and major PR milestones such as when the PR is first deployed on the lunar surface.' The assumption among many in the industry, though, is that at least one of the astronauts will fly before the rover is delivered, and possibly as soon as the Artemis 4 mission, the second crewed landing, in the late 2020s.
