NASA wants a shield big enough to cover both the spacecraft while it's traveling and the living areas humans will establish on the moon, on Mars or any other celestial body. However, carrying something big enough to cover settlements could take up all the space in a vehicle. Imperial College London engineer Helen O'Brien told The Guardian that "NASA wants something that is sufficiently packed and compact so that when you actually land on a planet you can expand it and it will provide maximum efficiency and protection from radiation."

The agency has been teaming up with Freelancer for its crowdsourcing projects for quite some time. Back in 2016, it asked people for help designing its cube robot's arm, which is now in its second phase. It also asked people to submit 3D models of tools Robonaut 2 can use aboard the ISS, including an RFID scanner, a grapple hook and a handrail.
