Tonner, Calgary, Alberta, Canada, Age: 42
Question:
When exiting the shuttle for a
space walk, do you sense a temperature change?
Grunsfeld:
David, that's a great question. The temperature in space is kind
of hard to define 'cause there aren't very many molecules on which
temperature is defined. But we certainly do radiate in our space
suits and we certainly generate a lot of heat inside. So it kind
of depends on what your workload is and whether it's day or night.
I find that at nighttime my hands and feet do get a little cold,
and to compensate, we have heaters on the gloves. And then during
the daytime or when I'm working hard -- I get nice and toasty inside
the suit -- we have a little thermostat that we use to adjust the
temperature so that we can make sure and stay cold. Good question!
