Projects submitted to this theme category should:
- Relate to one or more objects of our Solar System (Sun, planets, dwarf planets, moons, comets, asteroids, rings, dust etc). Earth-based or spacecraft observations can be included, however, without focusing in technical details regarding spacecraft payload, instrumentation, software etc.
- Projects may also be related to a physical process that takes place in the interplanetary space and is being or can be observed by in-situ or remote sensing. Combination between the existing theoretical knowledge and actual or proposed measurements could be involved. Projects may also be related to Earth as a planet and its interaction with other solar system objects (Geospace) on a global scale.
