Maximizing scientific accessibility and productivity of astronomical data.

The Barbara A. Mikulski Archive for Space Telescopes (MAST) is a NASA funded project. We provide a variety of astronomical data archives focused on scientific data sets in the optical, ultraviolet, and near-infrared parts of the spectrum. MAST is located at the Space Telescope Science Institute (STScI).
