Python for heliospheric and planetary physics

HelioPy is no longer developed

As of January 2022 HelioPy will no longer be developed or supported. Most of HelioPy's functionality is now implemented elsewhere:

Finding/loading in-situ data

sunpy version 3.1 (released October 2021) has support for reading CDF files. It also has functionality to search NASA's CDAWeb via. sunpy.net.Fido, which provides access to in-situ data from a large range of in-situ heliospheric observatories.

Generating spacecraft trajectories from SPICE kernels

The astrospice project re-implements all of this functionality, in a much more user and maintainer friendly codebase. It's currently actively developed, and accepting bug reports or feature requests.
