Of course we should go again. We have barely scratched the surface of Lunar exploration. We know next to nothing about what is beneath the regolith. We have not explored for caves and lava tubes. No astronaut has yet stayed on the Moon over the Lunar night! We need to prospect for water, helium 3, uranium and all the other stuff we haven't found yet.

This poll will not be too useful however - since only us space nuts are voting here. We are polling the choir! close(-)

I was aboard a sail boat in Santa Monica Bay (just off shore from the Los Angeles airport). The three of us on the boat listened to the landing on a portable radio. It was memorial moment! close(-)

To specifically answer Slenkar's last sentence question: Both the lander stage and the ascent stage use nitrogen tetroxide (N2O4) as the oxidizer - not oxygen. In the illustration look just under the RCS nozzles on the left edge of the ascent stage and note the word "oxidizer" with an arrow pointing to the nitrogen tetroxide tank which is similar in size to the red fuel tank. close(-)

One crossing is northgoing and the other is southgoing. Only the northgoing crossing can be used.
