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.</TD></TR><TR bgcolor="#333333"><TD valign=top>SkyMan1958</TD><TD>Isn't Toyota developing a "rover" for the lunar surface for the Japanese participation in Artemis?</TD></TR><TR bgcolor="#494949"><TD valign=top>Paul78zephyr</TD><TD><BLOCKQUOTE>In addition to the proven expertise brought by the teammates, Northrop Grumman has engaged Apollo astronauts Dr. Harrison (Jack) Schmitt and Charles Duke...</BLOCKQUOTE> I'm surprised that they haven't engaged with the only living person that actually drove an LRV on the moon.</TD></TR><TR bgcolor="#333333"><TD valign=top>Robert Pearlman</TD><TD>David Scott may have been approached and declined to participate.

Three companies have been selected to develop a lunar terrain vehicle for the Artemis program:

NASA describes the LTV as a "hybrid of the Apollo-style lunar rover that was driven by our astronauts and an uncrewed mobile science platform."

The agency will issue a subsequent request for task order proposal to eligible provider(s) for a demonstration mission to continue developing the LTV, deliver it to the surface of the Moon, and validate its performance and safety ahead of Artemis V. NASA anticipates making an award to only one provider for the demonstration. NASA will issue additional task orders to provide unpressurized rover capabilities for the agency's moonwalking and scientific exploration needs through 2039.
