Two astronauts work in the payload bay of space shuttle Columbia in March of 2002, completing upgrades to the Hubble Space Telescope. The mission was the fourth visit to Hubble since its launch in 1990. A crew of seven astronauts performed five spacewalks, adding an advanced camera, new solar panels, new steering equipment, and a more efficient power system to the orbiting telescope.
