“I am humbled and excited by new opportunities for me to support and share the amazing work NASA is doing to help us travel farther into the solar system and work with the next generation of science and technology leaders.”

“I believe in exploration, and I will miss being on the front lines of that endeavor. On one hand, I look forward to going home, but it's something that's been a big part of my life, and I'm going to miss it.”

“There are few aspects of everyday life that aren't touched by the technologies developed for space travel.”

“What we look for are people that are technically competent. You need a background in a scientific field, whether it's as a scientist, an engineer, medical doctor, or, you know, a person that's in the military with some kind of technical background.”

“I went to the University of Maryland for a year and was considering maybe, you know, being a medical doctor but decided my other interest was maybe flying airplanes in the Navy and just kind of changed my mind and changed schools and changed majors and decided to focus a hundred percent on that.”

“It's a combination of science, maintenance, and general housekeeping. And then, occasionally, robotics activities or a spacewalk you might get to do.”

“The majority of astronauts have to change their eyeglasses while in space. They bring eyeglasses with them and typically change a few months into the mission.”

“People do really well on space missions, but it's the physiological, the medical stuff, the stuff like radiation, loss of bone mass and muscle mass and density. It's those things that we need to figure out.”

“We don't do laundry because that requires a lot of water, and water's at a premium up here. Plus, it'd be pretty complicated, I think, to make a space washer, although I guess you could do it.”

“If you go on a journey to Mars and get into deep space, there is several hundred times, maybe 300 times the radiation.”
