Carrie
Fisher famously told the story of how, during the making of the Star Wars movies,
director George Lucas convinced her to go commando under her costumes, because,
“there is no underwear in space”. So off with the bra and panties!
According to
what Lucas reportedly told Fisher, in space, when one is weightless, the flesh
expands – and normal underwear would become too small and constrictive. Is this
true?
Another
space film which received some criticism on the underwear issue was Gravity.
Sandra Bullock’s character floats weightlessly in the space station in
boy-short undies and a singlet. According to a professional astronaut, this
just does not ring true at all...
It seems
that attire in space is anything but sexy.
So what do astronauts
wear under their space suits?
Underneath
the heavy and cumbersome space suit, an astronaut wears a liquid cooling and
ventilation garment. This resembles a set of thermal underwear, with cooling
tubes for water to keep the body temperature stable. And underneath this? Adult
diapers, or nappies.
Called
Maximum Absorbency Garments (MAGs), they have extra absorbency properties and are
worn during lift off, landing, and “space walking”, to absorb what would
usually be deposited in the toilet. Both male and female astronauts wear them.
While in all possible instances the astronaut will use lavatory facilities on
the space station instead, the MAG provides peace of mind. Space suits are not
easy to get on and off.
NASA
astronauts are given MAGs for launch, spacewalking, and re-entry attempts. They
also drink a large amount of salty water before re-entry as fluids are not
retained in zero-gravity; this prevents them from fainting when being
re-exposed to gravity on Earth.
These
undergarments become drenched in sweat – apparently the human body gets hot out there.
And what
happens to the dirty underwear? Apparently dirty laundry gets tossed into a
resupply ship which is unmanned. When the ship is chock full of rubbish
(including those adult nappies), the hatch is closed, it is undocked, and
floats off into space to fall into the atmosphere – where it burns up on its
fall towards Earth. Now we all know what is in space dust...
