Watch Astronauts Test Orion Spaceship Door for Future Mars Trips

NASA's Orion capsule could help astronauts on their way to Mars and other space locations someday. This week, a group of ground-based astronauts demonstrated the kind of testing that Orion is undergoing before it ever carries crewmembers into space. In a short video released by the space agency, three NASA astronauts are shown testing the docking hatch — which would connect the capsule to a larger vehicle in space — on a mock-up version of Orion.
