NASA’s Exo-brake ‘parachute’ to help return small spacecraft to earth

NASA’s Exo-Brake will demonstrate a critical technology leading to the potential return of science payloads to Earth from the International Space Station through the deployment of small spacecraft in early 2017, NASA reports.

An Exo-Brake is a tension-based, flexible braking device resembling a cross-parachute that deploys from the rear of a satellite to increase the drag. It is a de-orbit device that replaces the more complicated rocket-based systems that would normally be employed during the de-orbit phase of re-entry.

“The Exo-Brake’s current design uses a hybrid system of mechanical struts and flexible cord with a control system that ‘warps’ the Exo-Brake – much like how the Wright brothers used warping to control the flight behavior of their first wing design,” explained Marcus Murbach, principal investigator and inventor of the Exobrake device.
