One of the images of the target space debris taken during the "fixed-point observation" (H-IIA upper stage, which launched Greenhouse Gases Observing Satellite (GOSAT), also known as Ibuki in 2009).
The Japan Aerospace Exploration Agency (JAXA) advanced the Commercial Removal of Debris Demonstration (CRD2) Phase I project, under which the demonstration satellite Astroscale’s ADRAS-J successfully captured images of space debris, a non-cooperative target, through "fixed-point observation." These images have been released by Astroscale Japan Inc.
The "fixed-point observation service" is one of four services that JAXA requires for Phase I of CRD2. This service involves observing the target debris from a fixed point in the target's orbital coordinate system and providing continuous images of the target with the required image quality and data volume.
