The Commercial Smallsat Data Acquisition (CSDA) program evaluates and procures data from commercial vendors that advance NASA’s Earth science research and applications activities.
Currently, data acquired during the evaluations of Planet, Maxar (formerly DigitalGlobe, Inc.), and Spire Global are available. Data from the Teledyne Brown Engineering, Inc., DLR Earth Sensing Imaging Spectrometer (DESIS) also are available through a separate collaboration with the International Space Station (ISS). See the table below to learn how to access vendor-specific data. All data products are available through CSDA at no cost to authorized researchers and are subject to scientific use licenses.
The commercial data currently distributed by NASA are available under different scientific use licenses and various access portals. Please see table below for data access portals and vendor-specific end user license agreement (EULA) information. Check back for updates on new data acquisitions.
