Spacewalkers take extra safety precautions for toxic ammonia
CAPE CANAVERAL, Fla. (AP) — Spacewalking astronauts had to take extra safety precautions Saturday after possibly getting toxic ammonia on their suits from the International Space Station’s external cooling system.

Acaba was barely outside an hour when he had to replace one of his safety tethers. Spacewalking astronauts always have more than one of these crucial lifelines in case one breaks. They also wear a jetpack in case all tethers fail and they need to fly back to the space station. (NASA via AP)
