Documentary on astronaut's near-drowning on spacewalk will play at Space Center Houston

Before conducting spacewalks outside the International Space Station, astronauts prepare for all kinds of disaster scenarios: suit leaks, loss of consciousness, accidental detachment from the station. Drowning certainly wasn't one of them -- until five years ago, that is. Space Center Houston will hold a free showing of a documentary recounting an astronaut's near-drowning incident on a 2013 spacewalk on July 14.
