What this work contributes
The mission team reports controlled solar sailing in low Earth orbit, including sustained intervals of increased apogee and orbital energy. Its 32 m² sail and twice-per-orbit attitude maneuvers show that geometry, control, and photon momentum can produce useful propulsion together.
Where the evidence stops
Atmospheric drag continued to matter and the mission ended in November 2022; demonstrating orbital-energy management does not demonstrate atmospheric lift or reactionless thrust.
