Was talking with katie coleman who will be flying in a couple months to the space station for her six months, and she was in the buoyancy last week running through -- before they did the space walk, the procedures that they are doing up there now. to make sure that all that works before they actually do it in space, right? >> absolutely. so the coordination that you have here is, you know, years ago people had who say, well, what happens if the coolant pump fails, so let's carry some extra coolant pumps and get you familiar with what's going on. so the astronauts are up there as engineers, and...

And she said last night, it's like getting kicked in the stomach. she is torn between the fact that a dear family friend is gone and her father wasn't on the airplane. it is something that i'm sure someday it will hit me a lot harder than it has right now. but so far it's there. >> needs time to settle in. >> it does. >> we all know the public face of ted stevens and certainly over the last day, we've heard a lot more about things that we didn't know about him, give me one recollection or one warm spot that you remember about ted stevens. >> the man was loyal to a fault, to all of his staffers...

Of course, i went instantly to the internet to see what i could learn about it. mostly what i learned was that it was very, very rare and that anybody who was diagnosed with it died either within a few months or if they tried chemo, they might buy themselves an extra year. from there, my gut just told me there's something wrong. i felt fine. they ran a cat scan, bloodwork. couldn't find any other evidence of that cancer and eventually making a very long story short, as you can imagine, i was able to show that i didn't have cancer at all. and eventually that was confirmed by the national instit...

So the coordination is much more complex than that. >> here's the tricky part of that. it's all planned, they've got those replacement modules on the space center. but here's the thing. they went out on saturday, and something didn't budge the way it was supposed to. so i was joking yesterday that it's almost -- you've got to be -- with all that training, these space walkers, john, have got to be a bit like macgyver when they're up there. >> well, this is not just like macgyver, but actually, you have to be very versatile. and i think something else that's very interesting about this is that t...
