From sending the Curiosity Rover to Mars, to launching a unique study involving identical twin astronauts, NASA has done some amazing things recently.
Perhaps no feat is as impressive, simple and low-cost, though, as the agency's move to attach GoPro cameras to two of its astronauts. During spacewalks conducted earlier this year on the International Space Station (ISS), NASA strapped GoPro cameras to the suits of Barry "Butch" Wilmore and Terry Virts.
The footage is the closest most of us will ever come to actually being in space, and it is awe-inspiring.
The spacewalks aimed to reconfigure the ISS for the arrival of future commercial crew and cargo vehicles, as well as to conduct other maintenance measures.
Here is the full, hour-long footage of one of the spacewalks:
