Maximizing scientific accessibility and productivity of astronomical data.

The 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).

Mission Update: #TESS Sector 30 ingest has begun. Light curve, target pixel, and data validation files will start appearing in Portal and API later today and over the weekend.

Misson Update: #TESS Sector 30 taking a little longer to download due to slightly longer Sector duration (due to orbit details) --> more FFI files! So ingest should start tomorrow (Friday).

Mission Update: #TESS Sector 30 ingest is expected to begin as soon as tomorrow (Nov. 18th). If not, it will likely be the following day. An announcement will be made when ingest begins.
