Everywhere we look on the Ocean of Storms we see something we want to describe to our scientists, photograph, and bring back to planet Earth. Here is an angular rock that might have been blown out from deep beneath the surface by an impacting meteorite, perhaps traveling at almost 36,000 miles per hour.

Boy, I hope none of those meteorites show up today, or tomorrow either, during our second three-and-one-half hour-moonwalk. This moonwalk is not without risk, but to Pete and me, it is well worth it.

Right now I wish I remembered some of that erudite descriptive terminology we learned in our geology training. It is hard to think clearly about geology, as my mind seems full of thoughts I must remember to stay safe. I hope Pete is thinking more clearly about geology than I seem to be.

Safety is always job one. For example, Pete and I must be ready to quickly and accurately execute the correct procedures if our spacesuit starts losing pressure. And what are we supposed to do if we lose communications with each other, or mission control? And how are we doing on our planned timeline?

Well, there is a lot to think about, and thank god for the months and months of comprehensive training. NASA has the right philosophy. Experience everything we might encounter on our space mission in training, until it becomes familiar, with no surprises.

Of course, it’s the events that none of us thought about prior to flight, we wonder about the most.
