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

NASA is about to launch and test a new solar sail. Called the Advanced Composite Solar Sail System, it could advance future space travel and expand our understanding of our Sun and Solar System. Credits: NASA’s Ames Research Center

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 is Testing out new Composite Materials for Building Lightweight Solar Sail Supports

Space exploration is driven by technology – sometimes literally in the case of propulsion technologies.  Solar sails are one of those propulsion technologies that has been getting a lot of attention lately.  They have some obvious advantages, such as not requiring fuel, and their ability to last almost indefinitely.  But they have some disadvantages too, not the least of which is how difficult they are to deploy in space.  Now, a team from NASA’s Langley Research Center has developed a novel time of composite boom that they believe can help solve that weakness of solar sails, and they have a technology demonstration mission coming up next year to prove it.
