Small Satellites Program Stuttgart

The Small Satellites Program in Stuttgart was initiated in 2002 by the Institute of Space Systems. To allow the development of satellites despite high space transportation costs it was necessary to apply miniaturisation and new space technologies.

The first project of the Small Satellites Program is called Flying Laptop. It shall provide validation of new technologies and non-spacequalified components in low earth orbit. The gained knowledge of Flying Laptop will be used in the development and operation of its successors Perseus and Lunar Mission BW1.

The project Perseus will, as its predecessor, provide testing for new technologies as well as the qualification of the new developed electric propulsion system for the following project Lunar Mission BW1. In addition Perseus will perform UV astronomy during its science phase.

Lunar Mission BW1 is the final and at the same time most challenging project of the Small Satellites Program in Stuttgart. The objective is to reach Moon orbit and to perform scientific experiments with a satellite of approximately 200 kg of mass. This objective can only be achieved by the application of an electrical propulsion system, which provides a higher specific impulse compared to chemical propulsion systems and thereby allows a propulsion system with a relatively low mass.
