Being a scientist, I am very excited about the use of a laboratory in space, being able to contribute to things that we don't even fully realize we are able to learn in space yet.

[There's] a very broad range of science that will be done on board, and these kinds of experiments cannot be done anywhere else, under any other type of circumstance. So like I said, being a scientist myself and knowing what capabilities we're providing to humankind with the space station is very exciting; I'm very proud of it.
