Our scientific opportunities support the community through six distinct modes of operation. Links to proposal templates or on-line submission forms are provided for each individual tool.

Find explanations, forms of applications and an overview of current and past activities.

Workshops are selected by the ISSI directorate in consultation with the Science Committee. The Workshop programme and speakers are selected by a group of highly qualified experts acting as convenors. Each Workshop lasts a week and has up to 45 participants. Workshop participants work together to produce an on-line collection of peer-reviewed articles in Space Science Reviews or Surveys in Geophysics. This collection of review papers is then also published as a volume of the Space Science Series of ISSI (SSSI). All Workshop publications have Open Access status.

Multi-Spacecraft Observations and their Importance for Understanding Particle Dynamics in the Inner Heliosphere

The launch of the Helios-A spacecraft on December 10, 1974, followed by Helios-B on January 10, 1976, in combination with observations by spacecraft located at the Sun-Earth Lagrangian point L1 (e.g., ISEE-3, 1978 -1997), opened the era of multi-spacecraft particle and field measurements in the inner heliosphere. In th...
