NASA's Advanced Composite Solar Sail System (ACS3) will be visible from the ground. Find out when you can see it on the NASA ...

NASA's technology-demonstrating Advanced Composite Solar Sail System (ACS3) has a bent boom in Earth orbit, a newly released ...

And we believe it will fundamentally advance the technology of spaceflight. Solar sailing is elegant not only in concept but also in its efficiency. Once in orbit, there’s no fuel needed.

NASA's experimental Advanced Composite Solar Sail System (ACS3) is different, though. This vehicle could help NASA learn how to harness the Sun's limitless energy to sail through the vacuum of ...

NASA's Advanced Composite Solar Sail System (ACS3), a dazzling spacecraft designed to make use of the tiny amounts of radiation pressure exerted by sunlight for propulsion, is still spinning ...

Since they can propel themselves with limitless energy, solar sail-powered satellites could hover over a specific part of the planet, essentially following any orbit they want. The ESA is looking ...

It sounds like something from a science fiction novel: a spacecraft with sails being propelled solely by the rays of the Sun. This poetic image is set to become reality after NASA's Advanced ...

NASA’s Advanced Composite Solar Sail experiment, launched in April, aims to fix that. Instead of using chemical engines to maneuver and accelerate, it uses a solar sail—a large metallic film ...

NASA's Advanced Composite Solar Sail System (ACS3), a dazzling spacecraft designed to make use of the tiny amounts of radiation pressure exerted by sunlight for propulsion, is still spinning through ...

Novelists, poets, and scientists have envisioned spacecraft powered by solar sails since the 1600s. But now this fanciful concept is actually entering into reality.
