Notes

All operating past designed end of life, and will be decommisioned if a major failure occurs, or when the inclination becomes too great to make the satellite worth keeping in service. I-603 got stranded in the wrong orbit after a launch problem, and had to be rescued by the Space Shuttle! Endeavour carried out the rescue on her maiden flight in 1992.

1    inclined 2.4 degrees by September 2004
