During initial on-orbit checkout of the Hubble's systems, a flaw in the telescope's main reflective mirror was found that prevented perfect focus of the incoming light.

This flaw was caused by the incorrect adjustment of a testing device used in building the mirror.

Fortunately, however, Hubble was designed for regular on-orbit maintenance by [[Space Shuttle]] missions. The first servicing mission, [[STS-61]] in December [[1993]], fully corrected the problem by installing a corrective optics package and upgraded instruments (as well as replacing other satellite components). A second servicing mission, scheduled for March [[1997]], installed two new instruments in the observatory.
