Posted by tourdemars to Humans To Mars at May 8, 2014 7:19 AMIn the past NASA has asked its spacewalking crews to come up with a set of hand signals for communication in the event of audio loss. And for a long time this worked out very well. However after a water filled spacewalk on the Space Station last July, NASA determined that it would be better to have an official set. Before I left for Mars/Utah a friend of mine who trains astronauts asked that we come up with our own set of hand signals for comparison. Without having us look at the official NASA signals, they wanted to get an outside perspective on the issue and potentially incorporate our signals with theirs. And while our signals would be devised primarily for surface use, there is still enough overlap for zero g spacewalks that most of them will remain relevant (some will need modification though).
