&lt;title&gt;Role of contamination analysis in resolving concerns relating to the Hubble Space Telescope (HST) open-door deployment at the conclusion of the first servicing mission&lt;/title&gt;

Over the past two decades, the Hubble Space Telescope (HST) contamination control program has evolved from a ground-based integration program to a space-based science-sustaining program. On-orbit, the primary contamination requirement for the telescope was maintaining a low contamination flux in the optical path of the instrument. In addition, to maintain the scientific capability of the telescope, the contamination requirements and specific contamination controls from the second- and third-generation scientific instruments and orbital replacement units were captured within the HST contamination control program. Contamination controls involving the Orbiter, astronauts, and mission were developed for on-orbit operations and four servicing missions. Long-term on-orbit scientific data has shown that these contamination controls successfully protected the HST from contamination.
