Life in space, nobody would ever have thought about it. Recently, two astronauts of NASA agency had a spacewalk to put a high definition camera on outside surface of ISS and change a fuse which was damaged.
They spent 6 hours and 49 minutes total in space outside International Space Station and finished their several tasks very fast. The name of both astronauts is Randy Bresnik, commander of expedition 53, and Joe Acaba, employed as Flight Engineer at NASA.
Bresnik completed various tasks which include setting up a radiator grapple bar, work for additional pump modules installed on separate storage platforms so that in future the robotic replacement process could become easier. Another astronaut named Acaba had to do different task. He lubricated the robotic arm with grease.
Whiting said,
"He nearly finished prep work on the second, but that work will be completed by future spacewalkers".
Bresnik completed fifth spacewalk in his career and spent 32 hours total in space outside ISS, while Acaba finished third spacewalk which took 19 hours and 46 minutes in total.
