[edit] Mission

STS 51 was the seventeenth flight of the Discovery orbiter. Its main mission goals were to deploy the Advanced Communications Technology Satellite (ACTS) and ORFEUS-SPAS. In addition to the the two spacecraft in the cargo bay, STS 51 also carried the Limited Duration Space Environment Candidate Materials Exposure (LDCE) experiment. Mid-deck experiments included the fourth flight of the Chromosome and Plant Cell Division in Space experiment (CHROMEX 4), the third flight of the Radiation Monitoring Equipment (RME-III), the Air Force Maui Optical Site (AMOS), the second flight of the Auroral Photography Experiment (APE-B), the Commercial Protein Crystal Growth (CPCG) experiment, the first flight of the High-Resolution Shuttle Glow Spectroscopy (HRSGS-A) experiment, the Investigations into Polymer Membrane Processing (IPMP) experiment, and more IMAX photography.

[edit] EVA

Extravehicular Activity (EVA) conducted by Carl E. Walz and James H. Newman, 7 hours, 5 minutes. Walz and Newman conducted tests in support of the Hubble Space Telescope first servicing mission and future EVAs, including International Space Station assembly and maintenance.
