NASA astronaut Dottie Metcalf-Lindenburger (white suit on the left) and ESA astronaut Timothy Peake (white suit on the right) install a large mock-up to evaluate the best ways to set up a large payload on the surface of an asteroid.

In this configuration, Dottie is secured to a mini-sub simulating a space exploration vehicle, while Timothy is wearing a jetpack.

The mini-sub is driven by Andrew Abercromby, NASA Deputy Project Manager for the Multi-Mission Space Exploration Vehicle.
