MAST archives a variety of spectral and image data with a range of data characteristics. To see a complete list of missions with data archived with MAST, click on the Mission Link in the top menu bar. MAST also provides a large suite of searches. In addition to customized searches for each mission, MAST provides several cross-mission searches.

MAST also archives sets of High-Level Science Products (HLSP). Users may search for High-Level Science Products by target or coordinates by using the HLSP search page. MAST actively solicits submission of High-Level Science Products related to our missions and we provide guidelines contributing them to MAST.

The MAST Users Group provides essential user perspectives on archive operations and development, including suggesting priorities for short and long term operational and scientific enhancements to the archive.

Although there is no cost involved in retrieving data from MAST, researchers are requested to include an acknowledgement (as shown in the MAST Data Use Policy) in publications that make use of MAST.
