In this short scene, the crew talks about the lunar aurora, which they've just seen. They've seen it before, but this is the first time they're seeing it from the ground. The crew is worried about debris in the path of the comet, but they don't know what's going to happen until they see it. The guys are worried about the experiment equipment, which has been taken out of the capsule and put into a "sleep mode" . They wonder if the guy is sleeping in the cave, too, but he's just pretending to be asleep. They decide to turn off the external camera, which is supposed to capture the aurora. They think the aurora is coming from the capsule's regolith , and that's why it looks like it's coming from inside the capsule. They figure that if they follow their training, they'll be able to handle it.
