NASA’s Next Solar Sail is About to Go to Space

Everyone knows that solar energy is free and almost limitless here on Earth. The same is true for spacecraft operating in the inner Solar System. But in space, the Sun can do more than provide electrical energy; it also emits an unending stream of solar wind.

Solar sails can harness that wind and provide propulsion for spacecraft. NASA is about to test a new solar sail design that can make solar sails even more effective.

NASA Tests Water Powered Spacecraft in Orbit

Picture two tissue box-sized spacecraft orbiting Earth.

Then picture them communicating, and using a water-powered thruster to approach each other. If you can do that, then you’re up to speed on one of the activities of NASA’s Small Spacecraft Technology Program (SSTP.) It’s all part of NASA’s effort to develop small spacecraft to serve their space exploration, science, space operations, and aeronautics endeavors.
