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...

Unsolved Mysteries of the Uranian System

Almost four decades after the lone in-situ encounter of the Uranian system by the Voyager 2 spacecraft, our understanding of the system is still significantly lacking with many more open questions than answers. This is increasingly true as the community sets its sights towards future exploration of the system and revis...

Stellar Magnetism and its Impact on (Exo)Planets

Stellar magnetism influences the radiative, particulate, and magnetic output of stars across a vast diversity of time scales ranging from seconds, decades, to millennia and indeed stellar and planetary evolutionary timescales. This magnetically mediated activity has profound influence on stellar astrospheres and the (e...

What’s under the H0od? Towards consensus on the local value of the Hubble constant

The objective of the workshop is to reach a community consensus view on the state-of-the-art knowledge of the local distance ladder using the broadest possible variety of methods available today, in order to obtain the most robust determination of the local value of the Hubble Constant to date, and to strengthen our un...

Exocomets: Bridging our Understanding of Minor Bodies in Solar and Exoplanetary Systems

The main goal is to bring together researchers working on exocomets, relevant areas of exoplanetary research and protoplanetary disks, as well as Solar System comet researchers. It will provide a forum to discuss recent progress in exocomet research, transfer knowledge between fields and prepare for the utilization of ...
