Living Quarters for four crew
something to think about. In space simple things that you need
to do all the time become problems. List some (our list is
strapped to a board may seem a very uncomfortable way to spend
a night, but in weightless conditions this is the best way to
sleep. With no "right way up", you cannot "lie
down" to go to sleep. In order to simulate the usual sensation
of a bed, a board is used. Because there is no gravity pushing
you into it, it feels like a very soft mattress. You need to be
strapped in, because otherwise as you breathe out you will push
your mass across the cabin . So you will strap yourself
into a thin sleeping bag, attached to a board, with straps across
your head and chest to keep your head from moving and your arms
from floating out in front of you and accidentally knocking something.
You may want ear plugs to cut out the noise and an eye mask to
keep the light out - remember you will have 45 minutes of daylight
every hour and a half!

you come up with any of these?
Using the toilet
this module you have been allocated your personal quarters, this
might have storage drawers, cupboards, a desk, and a bed - something
like a sleeping bag attached to one of the walls. You will experience
weightlessness on board the space station, so your body has no
real idea of "up" and "down" and all surfaces
can be used (walls, ceiling, floor are all as good as each other
for placing furniture). But remember this will also mean that
anything that isn't attached will float around. You have the choice
of a colour scheme to suit your own preferences.
3: a hair cut - upsidedown or not? (top). Owen Garriott
trims the hair of commander Alan Bean. Note the vacuum hose to
collect the trimmings. Shaving: this is Commander Alan Bean on
Skylab 3 (lower). What happens to the floating stubble?
This was a problem because it floated around in the air for days
and got into everything! In the end the crews gave up shaving
- see image of the Skylab 4 crew with beards. But what if you
want a spacewalk? How well does a spacesuit fit a man with a beard?
Can you think of a solution to the shaving problem?
are not exempt from the hair problems, either. Many women like
to have long hair. In space this floats at bizarre angles and
can become a work hazzard as well as just an inconvenience. Can
you come up with any solutions to the long hair problem, assuming
the lady doesn't want to wear a crewcut?
is out of the question, not only because of the amount of water
you would use, but also because it would float all around your
head as well as your body. You will take a space shower, which
uses much less water. These were developed for Skylab, the US
manned mission and require an enclosed shower cubicle which controls
the movement of the water droplets by blown air and vacuum pumps.
You require much less water to wash in under weightless conditions,
as the droplets stick to the skin better.
the smallest room in space has to take into account weightlessness!
To go to the toilet there are two main points, keep yourself stuck
firmly to the seat (by using the seatbelt and handgrips) and make
sure the suction is working. There is no water flush, it is all
done by blown air and just the right amount of suction!
habitat module has four crew quarters and a shared shower and
does water do when it is not being held down by gravity?
Can you think of some problems washing and going to the toilet
could cause in the space station?
How do you think these have been solved?

do you see what you are doing?
do you get water in?
do you get soap in?
do you stop the water and soap spraying everywhere and drifting
do you collect the waste?
do you dry your hands?
you can't take your hands out and flick water everywhere. It would
drift around for days and may get into unwanted places such as
