In
space, there’s no up or down—it’s a 360-degree world and that can be
extremely disorienting, as Chris Hadfield learned shortly after getting suited up
today at the
NASA Johnson Space Center’s Virtual Reality lab, where he took a “spacewalk” with
Jeremy Hansen,
one of Canada’s newest astronauts.
Despite feeling mildly seasick as he
roamed the outside of the International Space Station, it was a thrill.
At Johnson’s VR lab, astronauts practice for all sorts of situations they might encounter in real life on the ISS.
Canadian
Chris Hadfield,
who’ll assume command of the ISS in March, is working a lot in VR right
now to master SAFER, a propulsive backpack that can save spacewalking
astronauts
should they drift away on an EVA.
In the VR lab, there’s a console
filled with monitors where astronauts can operate a virtual Canadarm;
and there’s another area where astronauts donning VR helmets can
practice climbing all over the ISS to do a repair.

A software technician helped set Hadfield
up: she put a massive helmet over his heads, and slipped wired gloves
onto his hands.
As soon as the helmet was lowered over his eyes, Hadfield felt
submerged in a different world. In front of him he could see the Space
Station, and beyond it, the blue curve of Earth.
It was beautiful, but stomach churning: the perspective is nothing like on the ground. You can move in any direction, and this makes you feel immediately disoriented (no wonder
even seasoned astronauts can get lost aboard the ISS).
The technician helped him
figure out how to grab a railing and climb around; eventually he could
see the other astronaut in his spacesuit in front of him, waving.
It’s easy to see why this type of practice is important for astronauts, especially when paired with work in the
Neutral Buoyancy Lab,
a massive swimming pool containing a mockup of the ISS where they run
through drills in their spacesuits but underwater in the NBL, there’s
still an “up” and a “down.”
That wasn’t the case in VR, nor is it in
space. When finally the helmet is taken off, his face
was white as a sheet but even while battling nausea, the experience was
so novel and exciting he didn’t want it to end.
Chris Hadfield said that the best part of the VR experience was when a
technician 'fixed' him to the end of the Canadarm2 to really give me a
view.
