The National Aeronautics and Space Administration (NASA) has launched its Advanced Composite Solar Sail System (ACS3) into space, marking a significant milestone in spacecraft propulsion. This innovative mission will utilize the propulsive power of sunlight to navigate the solar system, paving the way for future space exploration. The spacecraft will undergo rigorous testing more than 600 miles above Earth, evaluating the effectiveness of the solar sail technology. The mission is managed by NASA’s Ames Research Center in California, with contributions from Langley Research Center in Virginia and Rocket Lab USA, Inc. The Small Spacecraft Technology Program funded and oversaw the mission, which aims to further enhance solar sail technology for future missions.
