The pysat project supports both data-centric packages that primarily support the retrieval, management, and input/output aspects of the scientific workflow and analysis packages that provide task-specific tools.
The status of pysat supported packages can be found at the ecosystem status chart.
pysat supports many different data sets as Instruments and Constellations. Similar types of data and data from the same data repository are grouped together into separate packages. This reduces the amount of dependencies you may need to install, when you only want to use a small subset of the data pysat currently supports.
