I did see it just a few months ago in April when we flew on STS-83. That was a shorter version of this mission. It was quite a spectacular site to see the comet above the earth. I've seen sunsets and moonsets, but a comet setting into the atmosphere from above the Earth was really spectacular, and that was the most memorable part of the flight for me. Physically all astronauts try to stay in pretty good shape.
Most People run.
We have a gym that we all work out at and my main activity is I like to go swimming. So I swim a mile and a half almost every single day when back on Earth. That's the physical part. Mentally, you have to get prepared, you got to know all your materials and work really hard at it. For all these experiments the we're performing on the shuttle here we've been training for a year and a half to two years on each of the experiments to make sure we know exactly how to perform them inside and out.
