How many things need to go wrong for an astronaut to float away into space? Just how safe are they?

- jamesmontalvo3 14y agoI can't speak for Russian EVAs [1], but in US EVAs we always have a long tether reel attaching us to station. If we need to get further than that tether reel allows, we attach another tether reel before releasing the first. Additionally, we have a sort of jetpack called a SAFER [2] in case a tether (or the user) fails.
