The main issue is detection of water, which would show up as hydrogen in the elemental analysis. Failure to detect hydrogen is probably the most significant result at present:
Would we know already if water was coming up from the lunar depths?
Probably the floors of craters never subjected to direct sunlight at the poles would be the most likely surface indication. The rover had to navigate around a crater, might have been the place to look if they had the capability.
It might be possible to gather them and build a crude weapon to defeat the Gorn.
One small step for man, one giant leap for Gorn combat.
Less resources to be shipped from Earth for future habitats/missions that require a lunar base.
