What are the cases in which the space shuttle successfully repaired or recovered "sick" satellites?

1984, the space shuttle Challenger repaired the solar observation satellite "Solar Peak Year" for the first time in space, which was the first time that the space shuttle repaired the satellite. 1993 and 1997, the space shuttle repaired the Hubble telescope twice in space, making it more "discerning". The first satellite launched by China's Long March rocket-"Asia 1" communication satellite is also the American "Western Union Satellite 6" communication satellite recovered from space in 1984. It failed to enter the orbit due to the failure of the last stage engine and "wandered" in space for half a year.
