Astroscale's on-orbit footage of its ADRAS-J spacecraft performing an autonomous close-proximity fly-around inspection of a spent Japanese H-IIA rocket upper stage (2024). This was rendezvous and inspection only, not capture or removal (capture is the future ADRAS-J2 mission). Autonomy attributed to Astroscale.
