Please use this topic to discuss NASA's request and the responses by industry for a human-class lunar rover to be used on Artemis missions.

I've always wondered about the sanity of a rover that can go much further than an astronaut can walk back to the lander if something goes wrong and still survive.

I assume there will be something to enable the astronauts to get back to the lander if the rover breaks down or gets stuck.

NASA specified a 3-mile (5-km) walk back limit to the landing site in the briefings (see page 40) it provided potential Lunar Terrain Vehicle (LTV) developers.

You can't walk back if your engine fails halfway across the Atlantic. Nor can you walk back if your LM ascent stage engine (or your SpaceX Starship engines) fail on the Moon. It hasn't stopped people exploring.

In time, it would make sense to establish semi-permanent caches of oxygen and cooling/drinking water at strategic locations to allow longer rover excursions, but at some point you have to remove the training wheels from the bicycle.

Isn't Toyota developing a "rover" for the lunar surface for the Japanese participation in Artemis?

In addition to the proven expertise brought by the teammates, Northrop Grumman has engaged Apollo astronauts Dr. Harrison (Jack) Schmitt and Charles Duke...
I'm surprised that they haven't engaged with the only living person that actually drove an LRV on the moon.

David Scott may have been approached and declined to participate. Or perhaps he is already working with one of the other teams.

Japan's participation in Artemis is centered on contributions to the Gateway. The Lunar Cruiser is a joint research study between JAXA, Toyota, TOMY, Sony and Doshisha University for a possible flight to the moon by Japan's own ispace, inc. At present, it is not part of NASA's Artemis' plans.
