Japanese space-sustainability company Astroscale has unveiled plans for a mission it says will be the world's first to inspect multiple defunct satellites in different orbits.
The mission, named In‑situ Space Situational Awareness-Japan 1, or ISSA-J1, is scheduled for launch in 2027 and will inspect two retired Japanese satellites in orbit. It follows the success of the company's Active Debris Removal by Astroscale-Japan (ADRAS-J) mission, which delivered stunning close-up footage of a spent rocket stage in orbit.
