Hubble Space Telescope (HST)

Backdropped by the horizon of Earth and the blackness of space, the Hubble Space Telescope (HST) floats gracefully after the release from Columbia’s robot arm at the conclusion of the very successful Servicing Mission 3B in March 2002. The event marked the fifth time that a space shuttle had set the great observatory into space. Those occasions were at its initial release in 1990, and at the conclusion of four subsequent servicing missions.
