Part II - Life on Skylab
11.10.03
Part I - The History of Skylab | Part III - The Legacy of Skylab
One of Skylab's most important functions was to study the feasibility of
long-duration space missions. As a result, the ongoing activity of astronauts
just going about their daily lives in orbit was one of the greatest of all
the scientific experiments aboard the station. Though they were free-falling
in Earth orbit, traveling at 16,000 miles per hour, the Skylab crew members
said that everyday life on the station was actually pretty normal.
The first Skylab crew enjoys a meal in space.
Days began on Skylab at 6 a.m. (Houston time) and lasted until 10 p.m. At the
beginning of each day, the astronauts would check the teletype machine to see
what their orders were from Mission Control for that day. The crew would then
use the restroom, weigh, and eat breakfast.
Their daily science assignments would rotate every day. Each took turns on
things such as solar observation, and the astronaut who was the "guinea pig"
for the medical evaluations one day would be performing those same
evaluations on one of his crewmates the next.
"Between 8 and 10 at night, we had free time," Carr said. "For the most part,
the most fun was looking out the window." Off-duty free time was often filled
with still more science experiments. "We had a number of other things to do,"
Garriott said. "We had the student experiments, for example."
The crews also had fun devising their own small experiments, some of which
were later turned into educational videos for students worldwide. Carr said
he enjoyed this hobby. "It was such an interesting thing to turn loose a blob
of water to see what you can do with it." They also pulled a classic prank on
mission controllers. The ground crew was shocked when Garriott's wife, Helen,
called down to them from the station. The roomful of controllers sat confused
until the crew burst into laughter - Garriott had recorded his wife's voice
before the flight, and rehearsed the prank with capcom Bob Crippen.
Extra-vehicular activities (EVAs) had been scheduled from the beginning to
change out the film in the Apollo Telescope Mount. However the EVAs
eventually became necessary to repair the station. During the EVAs, Garriott
said, it was a thrill to "look down this very long elevator shaft" to the
surface of the Earth. "It's quite an interesting view," he said.
Astronaut Owen Garriott participates in EVA to deploy twin pole solar shield.
None of the astronauts expressed any concerns about the potential physical
effects of the unprecedented spaceflight durations. Returning to Earth did
take a little adjustment, though. In addition to a few days of readjusting to
the physical effects of gravity, astronauts sometimes forgot that things do
not work the same on Earth as they do in space, attempting to let things
float as they would in microgravity.

我非常喜欢在有风有雨的季节计划自己;
有风有雨后的季节晒着阳光我昏昏睡去;
睡去的我依然在甜梦中将曾有过的温习;
温习昨天前天等等的种种激情与过去。
