I don't have any nicknames.

Then during the mission itself, I used the space shuttle's robot arm to release a satellite into orbit.

The pressure suit helps if something goes wrong during launch or re-entry - astronauts have a way to parachute off the shuttle. The suits protect you from loss of pressure in case of emergency.

Astronauts will remain the explorers, the pioneers-the first to go back to moon and on to Mars. But I think it's really important to make space space available to as many people as we can. It's going to be a while before we can launch people for less than $20 million a ticket. But that day is coming.

I do a lot of running and hiking, and I also collect stamps - space stamps and Olympics stamps.

The view of Earth is spectacular.

When you can feel that close to something you're used to seeing from this great distance, well, it changes a person.
