nasa begins test on E sail technology

NASA is developing the HERTS E-sail system which will use protons from Solar Wind to run spacecraft. With E-sail system it will take only 10 years to reach the edge of the Solar System. The Voyager took 35 years to reach the same spot.

Deep space exploration requires advanced technological systems for long haul flights. Aside from that, there should also be an unlimited supply of fuel to gas the trip up. But NASA is looking at a more sustainable source of energy for its future flights, by using HERTS Electric sail or E-sail, spacecrafts run by solar wind.

NASA's Marshall Space Flight Center teams are testing the technology to be used for the possible test flight of theHeliopost Electrostatic Transit System (HERTS) or the E-sail system. It is designed to send  spacecraft to the edge of the solar system faster and by using renewable energy as its fuel. It will cut the travel time to reach the edge of the Earth by more than half. The Voyager took 35 years to reach the edge of the Solar System, while the E-sail technology will only take 10 years to send a spacecraft to the edge
