Device Allows Paralyzed Man to Perform Complex Movements

Six years ago, he was paralyzed in a diving accident. Today, he participates in clinical sessions during which he can grasp and swipe a credit card or play a guitar video game with his own fingers and hand. These complex functional movements are driven by his own thoughts and a prototype medical system.

NASA Tests Revolutionary E-Sail Propulsion Technology

Testing has started at NASA on a concept called the Heliopause Electrostatic Rapid Transit System (HERTS), a propellant-less propulsion system that would harness solar wind to travel into interstellar space. “The sun releases protons and electrons into the solar wind at very high speeds -- 400 to 750 kilometers per second,” said Bruce Wiegmann an engineer in Marshall’s Advanced Concepts Office and the principal investigator for the HERTS E-Sail. “The E-Sail would use these protons to propel the spacecraft.”
