STS-109 (SM3B) was a Space Shuttle mission that launched from the Kennedy Space Center on 1 March 2002. It was the 108th mission of the Space Shuttle program,[1] the 27th flight of the orbiter Columbia[1] and the fourth servicing of the Hubble Space Telescope.[2] It was also the last successful mission of the orbiter Columbia before the ill-fated STS-107 mission, which culminated in the Columbia disaster.
The Hubble Space Telescope (HST) was placed in orbit during mission STS-31 on 25 April 1990.[3] Initially designed to operate for 15 years, plans for periodic service and refurbishment were incorporated into its mission from the start.[4] After the successful completion of the second planned service mission (SM2) by the crew of STS-82 in February 1997, three of the telescope's six gyroscopes failed. NASA decided to split the third planned service mission into two parts, SM3A and SM3B.[5] A fifth and final servicing mission, STS-125 (SM4) launched on 11 May 2009.[6] The work performed during SM4 kept HST in operation through 2021.[7]
