NASA and aerospace company, Aerojet Rocketdyne, have successfully completed qualification testing of the Advanced Electric Propulsion System (AEPS), which is a 12-kilowatt, solar electric propulsion (SEP) engine being built for use for long-term space missions to the Moon and beyond, and AEPS is being touted as the most powerful electric propulsion—also called ion propulsion—thruster currently being manufactured. For context, 12 kilowatts are enough to power more than 1,330 LED light bulbs, and the success of these qualification tests come after NASA announced the beginning of qualification testing in July.

A recent study submitted to Acta Astronautica explores the potential for using aerographite solar sails for traveling to Mars and interstellar space, which could dramatically reduce both the time and fuel required for such missions. This study comes while ongoing research into the use of solar sails is being conducted by a plethora of organizations along with the successful LightSail2 mission by The Planetary Society, and holds the potential to develop faster and more efficient propulsion systems for long-term space missions.

Going 1 Million Miles per Hour With Advanced Propulsion

Advanced propulsion breakthroughs are near. Spacecraft have been stuck at slow chemical rocket speeds for years and weak ion drive for decades. However, speeds over one million miles per hour before 2050 are possible. There are surprising new innovations with technically feasible projects.

NASA Institute for Advanced Concepts (NIAC) is funding two high potential concepts. New ion drives could have ten times better in terms of ISP and power levels ten thousand times higher. Antimatter propulsion and multi-megawatt ion drives are being developed.
