NASA - National Aeronautics and Space AdministrationHuntsville, AL – Testing has started at NASA’s Marshall Space Flight Center in Huntsville, Alabama, on a concept for a potentially revolutionary propulsion system that could send spacecraft to the edge of our solar system, the heliopause, faster than ever before.

The test results will provide modeling data for the Heliopause Electrostatic Rapid Transit System (HERTS). The proposed HERTS E-Sail concept, a propellant-less propulsion system, would harness solar wind to travel into interstellar space.

In this concept, long, very thin, bare wires construct the large, circular E-Sail that would electrostatically repel the fast moving solar protons. The momentum exchange produced as the protons are repelled by the positively charged wires would create the spacecraft’s thrust. (NASA/MSFC)
