Astronauts train to service Hubble (above) in a huge, water-filled tank that
simulates weightlessness. The 40-foot-deep (12 m) tank at NASA’s Johnson
Space Center contains full-scale underwater mockups of Hubble, its instruments, and the carriers that hold the instruments. The astronauts wear pressurized suits similar to those they wear in orbit. Credit: NASA
