How does the crew deal with medical
emergencies in space?
The Shuttle carries a series of medical kits called the Shuttle Orbiter
Medical System (SOMS) into orbit for use by two specially trained crew members
(Crew Medical Officers) for each mission. The crew members can use the kits
to deal with both minor and major illness/injury that might typically be
seen in a small emergency center. These include suturing lacerations, giving
injections, using intravenous fluids, antibiotics, and other medications,
and diagnosing and treating a variety of medical events during spaceflight.
How do astronauts in space
go to the bathroom and take care of their personal hygiene?
brush their teeth just like they do on Earth. There is no shower on the
Shuttle, so astronauts must make do with sponge baths until they return
home. Each Space Shuttle has a toilet that can be used by both men and
women. Designed to be as much as possible like those on Earth, the units
use flowing air instead of water to move waste through the system. Solid
wastes are compressed and stored onboard, and then removed after landing.
Wastewater is vented to space, although future systems may recycle it.
The air is filtered to remove odor and bacteria and then returned to the
Collection System for more about the orbiter's toilet.
Is there a danger of dehydration
The humidity here is at about 20 percent onboard the shuttle, so we do
notice that things dry out rather quickly, including us, and we try to
drink more water than we normally do on the ground. (Answered by STS-80 mission specialist Tom Jones.)
Does the crew all sleep at
the same time, or does someone have to stay awake to monitor systems?
During a single-shift flight, we all sleep at the same time. We have a
group of people in Mission Control who watch over us, and they have ways
of waking us up. They can set off an alarm up here in the shuttle that
will certainly get us out of the rack and get us looking at what they
want us to look at. So we do all sleep at the same time but we're being
watched over very carefully. (Answered by STS-80 commander Ken Cockrell.)
Is the crew still asleep
at the time of the wake up call?
Some crew members like to set their alarms a few minutes early so that
they are alert by wake-up. It's a nice time to be awake since the ground
is not going to call them unless there's an emergency. For those still
sleeping at wake-up, the wake-up music usually does a pretty good job
of clearing the cobwebs.
Does weightlessness affect
the crew's dreams?
I believe that weightlessness does affect the types of dreams I have experienced.
I tried to make a point of remembering what I was dreaming about last
night and I do remember some images of not walking but floating, so I
would have to say that the impression on my body and on my memory of floating
in space that I've done up to this point does re-manifest itself through
my dreams. I have not had, that I can recall, the experience on the ground
of dreaming of being weightless, although ever since I was a young boy
I dreamed that I could fly. I know that's a fairly common experience,
but perhaps that was anticipation of what I'm doing now, and perhaps now
when I dream of flying when I'm on Earth, maybe that's reaching back into
these memories. (Answered by STS-82 mission specialist, spacewalker Greg Harbaugh.)
