ISSA-J1 will use a 650-kilogram servicer to approach and inspect the retired Japanese spacecraft ALOS and ADEOS-II in distinct orbits using a single flight profile.
ISSA-J1 will target the retired Japanese spacecraft ALOS and ADEOS-II.
After inspecting ALOS, ISSA-J1 will transition to a different orbit to reach ADEOS-II.
ADEOS-II failed shortly after its 2003 launch.
ISSA-J1 will capture high-resolution imagery and sensor data to assess the structural integrity and rotational motion of ALOS and ADEOS-II.
