Peggy Whitson

48

1996

Two six-month tours on the International Space Station, in 2002 and 2007-2008

A walking laboratory for the long-term effects of zero gravity, Peggy explained how one's ability to think in 3D and intuit how to move objects in a different way than on earth is highly important. She said “The second time I went to the station, it felt like coming home. I adapted and got comfortable much quicker.“ "It's a nice plus that without the effects of gravity, everything is lifted while you're up there, so you look younger" added Peggy. She gamed twice, being confined in space without gravity for six months, both the times. The second time as the first woman commander, she racked up 377 days in space on her two missions, more than any other U.S. astronaut.

“Fitness is a lot more important than strength. With no gravity for resistance, muscles and bones deteriorate quickly up there, so every day we do an hour of cardio on a specially designed cycle or treadmill and an hour of resistance training. You need strength for space walks, as every motion works against the pressure of the space suits we wear, and it's very fatiguing. Exercising always made me feel more positive and upbeat afterward too.“ said Peggy Whitson.

Mesmerised by the view of earth's curvature on their orbit every 90 minutes she went on describing how one could see the layers of atmosphere, extended beyond the surface, met the blackness of space far across.

When Peggy returned her agility and quick motions, like dribbling basketball, were severely hindered. But with the help of a physical assessment for a month she was back to her pre-flight norm. She explained “exploration is a very important part of who we are, and if we want to literally expand our horizons, we have to keep doing it. Construction of the International Space Station shows we can expand those horizons culturally as well.“

47

1995

Three shuttle missions, in 2000, 2002, and 2007

The retired Air Force test pilot Pamela recalled the physical sensation of zero gravity, the magic, and how occasionally she dreams about it. “It happens a lot within the first week or two of landing, and it can be profoundly disorienting, especially when you wake up and you're not sure where you are, in gravity or not. It is fun to go back and visit, though“ she went on describing.

 

During deployment of a solar wing at the station a guide wire snapped tearing the wing and keeping it from providing full power. Melroy remembered how all were gathered to go over the final list of issues. “The whole crew was giving their input, and everyone was firing on all cylinders. I realized I didn't need to say anything. I kind of floated away and observed them. They were doing what they were supposed to do, pulling together, without needing to be guided in any way. That was the best moment for me."
