The ISS orbits around the Earth at a speed of almost 28,000 km/h, so when there is a repair to make outside of the station, the astronaut himself orbits at this speed. How does it feel to realize that your body travels at a speed of 28,000 km/h? (I mean emotionally, not physically, since there is no acceleration.)
Doing a spacewalk was the most exciting as well as the most challenging part of both of my space missions. The best way that I can describe the experience, other than "AWESOME!!" would be to say that it is a strange combination of the familiar and the outlandish.
What I mean by that is that you have done so much preparation for this event that many aspects feel perfectly normal. Your suit fits just like the ones you have worn on Earth; the switches are all in the same place and the glove fits like, well... When you get to the worksite, the bolts and electrical connectors are all in the same place as they were in the big pool that we use for training in Houston. Your tools all work the same way and even the Space Station looks very familiar.
Then you look out and see the entire east coast of the United States go flying on by - and that is totally outlandish!
