Space Shuttle Projects

This is the insignia of the STS-109 Space Shuttle mission. Carrying a crew of seven, the Space Shuttle Orbiter Columbia was launched with goals of maintenance and upgrades to the Hubble Space Telescope (HST). The Marshall Space Flight Center had the responsibility for the design, development, and construction of the HST, which is the most complex and sensitive optical telescope ever made, to study the cosmos from a low-Earth orbit. The HST detects objects 25 times fainter than the dimmest objects seen from Earth and provides astronomers with an observable universe 250 times larger than is visible from ground-based telescopes, perhaps as far away as 14 billion light-years. The HST views galaxies, stars, planets, comets, possibly other solar systems, and even unusual phenomena such as quasars, with 10 times the clarity of ground-based telescopes. During the STS-109 mission, the telescope was captured and secured on a work stand in Columbia's payload bay using Columbia's robotic arm where four members of the crew performed five spacewalks completing system upgrades to the HST. Included in those upgrades were: The replacement of the solar array panels; replacement of the power control unit (PCU); replacement of the Faint Object Camera (FOC) with a new advanced camera for Surveys (ACS); and installation of the experimental cooling system for the Hubble's Near-Infrared Camera and Multi-object Spectrometer (NICMOS), which had been dormant since January 1999 when it original coolant ran out. Lasting 10 days, 22 hours, and 11 minutes, the STS-109 mission was the 27th flight of the Orbiter Columbia and the 108th flight overall in NASA's Space Shuttle Program.
