Taking a spacewalk

Of course, NASA and the world’s other space agencies don’t send people on EVAs on a whim. It’s dangerous work (although no one has ever died or been seriously injured on an EVA). Astronauts working on the ISS report an initial period of severe disorientation, as their perspective flips from “hand-stand” to “surfboard” and back repeatedly. The problem is, the abstract shape of the ISS doesn’t give their brains any up or down cues to latch onto the way the space shuttle does.

Some great facts here.

It’s funny how we romanticize this stuff in our heads, but really they are just doing the most dangerous construction known to man.

Still, that view…
