When I did my spacewalks, it was during space station construction. So the shuttle was docked to the fledgling ISS at the time. So we would always stay tethered.

If you don't like airline food, you'll probably have the same impression of space station food. I would not fly to space for the food.

If we're going to complete the space station, we're going to need the shuttle. It's going to take a lot of resources.

Airline food is cooked in an oven and then kept warm. Space station food is often cooked in an oven and then thermo-stabilised, irradiated or dehydrated and then stored for a year or two before you even get to it.

While on the space station, I kept up with news a couple of ways - Mission Control sent daily summaries, and I would scan headlines on Google News when we had an Internet connection, which was about half the time.

I think both the space shuttle program and the International Space Station program have not really lived up to their expectations.
