A navigation page for on-site files, scientific papers, and links to additional resources.

The goal of the Resources page is the amalgamation of all work that has been done, or is being done, on the Helios Mission data by our team or any other person, group, team, organization, and/or universities unaffiliated with this project. And to then organize that information into a concise page that makes it easy for you to connect with the most useful source.

Our team has focused on reanalyzing the magnetic field and plasma experiments (E1 E2, E3, and E4) onboard Helios 1 and 2: summarized on the Reanalysis page of this website. Other groups have worked on different subsets of the Helios Mission. In the following sections we do our best to unify these different efforts.

Data, Documentation, and HTTP Site

Data Repository


The Data Repository organizes the available Helios mission files -- data, instrument papers, programs, and other documents -- and provides accessible, downloadable, links. Each file has a short description.

Instrument Documentation


The Instrument Documentation page organizes the available documentation by experiment. In the Data Repository some documentation is organized by means other than experiment.



The "HTTP site" is the primary location of all available files in this archive. This page shows the Helios mission files as are organized on the servers, with very limited information.

Science Papers

This page contains relevant scientific works that make use of the Helios spacecrafts' data, such as, dissertations, publications, and legacy documents.

1985 and before

Helios 1 was launched December 10, 1974.
Helios 2 was launched January 15, 1975.
A majority of the scientific works about the Helios Mission, were created within the first decade of the spacecrafts launch.

1986 through now

Helios 1 and 2 had primary lifespans of 18 months, however, both spacecrafts far exceeded their lifespans: the last transmission came in February 10, 1986. That is over one decade of solar data!
Post 1985, we see a significant decrease in scientific works.
