How does spacewalking compare to scubadiving?
I would say after doing three spacewalks that it compares very much with scubadiving. That’s why we practice our spacewalks in the pool. Many times during our spacewalks in the pool, in fact, after we have gotten about 25 to 30 hours of practice spacewalking in the pool, I actually felt like I was in space a couple of times.
