Helios Data Archive

SSL hosts the most comprehensive, single, archive of the in-situ Helios 1 and 2 data along with previously unavailable documentation on the different spacecraft instruments and their operation, datasets, and early data processing.

The Helios mission serves as a tremendous asset to the entire solar and heliophysics community. Its datasets withhold unique relevance for any study contextualizing and facilitating data analysis from Parker Solar Probe (PSP) and Solar Orbiter (SO) missions.
