Spacecraft Initiates First Communication from Beyond Earth's Atmosphere as It Readies to Unfold Remarkable Sails
Sailing Through the Cosmos: The Return of NASA's ACS3 Solar Sail
After a thrilling week-long voyage, NASA's miniature marvel, the Advanced Composite Solar Sail System (ACS3), sent a heartening signal home on the small hours of Tuesday morning. Preparing to embark on its stellar mission through the low Earth orbit, ACS3's contact with ground operatives was announced in a NASA blog post.
Launched aboard Rocket Lab's Electron rocket from New Zealand on April 23, ACS3 found itself gracefully orbiting around 966 kilometers above the Earth's surface – nearly double the altitude of the International Space Station. The mission team successfully established two-way communication and are now planning a date to deploy the sail once all commissioning tasks are attended to.
The deployment process is set to take around 25 minutes, and NASA has outfitted the mission with a suite of digital cameras to capture images of the sail during and after deployment. This will help assess the sail's shape and alignment.
NASA's ACS3,, an innovative testbed for new materials and deployable structures, is designed to push the boundaries of solar sail propulsion systems – with composite booms engineered to unfurl the solar sail once it reaches orbit. When fully unraveled, the solar sail will span an impressive 27 meters.
Solar sails cruise through space on photons emitted by the Sun, generating minute bursts of momentum that propel the vessel further away from the Sun. ACS3's initial voyage will last approximately two months, during which it will execute a series of precise maneuvers aimed at demonstrating orbit raising and lowering by utilizing only the pressure exerted by sunlight on the sail.
As the ACS3 unfurls its solar wing, it brings us one step closer to unlocking the mysteries of the Sun and our solar system. NASA asserted in their post, "The findings from this mission will pave the way for future space travel and deepen our understanding of our Sun and solar system."
