Spacecraft missions in the study of minor bodies

Spacecraft missions are very important to understand the exact chemical composition and the physical structure of asteroids and comets. Here is a detailed presentation of the many spacecraft missions operating today, and of past most important missions.

Present and future missions Past missions
Mission Rosetta (ESA) Mission Galileo (NASA)

All these missions have different characteristics and are of different kinds. Spacecraft missions can be classified as follows:

Moreover, comets and asteroids differ widely in their characteristics. For this reason missions have been planned to visit a widely diverse group of objects, obtaining very beautiful images and important scientific determinations of asteroids' and comets' composition. Whether these scientific experiments are in situ or remote, spacecrafts are designed to transport and operate a very heavy and sophisticated payload of scientific instruments that often are very different from ground ones.
