NASA's solar sail is tumbling, but that's part of the plan
Briefly

NASA's Advanced Composite Solar Sail System (ACS3) is testing innovative sail technology that harnesses solar radiation pressure for propulsion, aiming to revolutionize future space missions.
Data obtained from ACS3 will guide the design of future larger-scale composite solar sail systems for various purposes, including space weather warning and asteroid reconnaissance.
The ACS3 spacecraft was observed tumbling in orbit, which NASA clarified as a normal behavior while the mission team assesses its performance and evaluates its capabilities.
The ACS3 project exemplifies ongoing global efforts in solar sail technology, continuing a legacy that began with NASA's Mariner 10 and further advanced by other space agencies.
