STS-103 emblem depicts Space Shuttle Discovery approaching the Hubble Space
Telescope prior to its capture and berthing.
The purpose of the mission is to remove and
replace some of Hubble’s older and out-of-date systems with newer, more
reliable, and more capable ones, and to make repairs to the Telescope’s
exterior thermal insulation that has been damaged by more than nine years of
exposure to the space environment.
horizontal and vertical lines centered on the Telescope symbolize the ability to
reach and maintain a desired attitude in space,
essential to the instrument's scientific operation.
The preservation of this ability is one of the primary objectives of the
mission. After this mission, the
Telescope will resume its remarkably successful exploration of deep space and
will continue to be used to study solar system objects, stars in the making,
late phases of stellar evolution, galaxies, and the early history of the
Hubble Space Telescope as represented on this emblem was inspired by views
during previous servicing missions, with its solar arrays illuminated by the sun,
providing a striking contrast with the blackness of space and the night side of
