Astrid-2

Astrid-2 is a Swedish pioneering low-budget satellite mission, being the first micro-satellite dedicated to comprehensive auroral research. With a payload mass of less than 10 kg, new innovative techniques and low-mass solutions had to be used for developing the various sensors and sensor deployment systems. Since launch on 10 December 1998 Astrid-2 has collected more than 20 Gibytes of high-resolution and high-quality data on auroral electric and magnetic fields, particles, emissions and plasma characteristics from approximately 3000 polar orbits at an altitude of about 1000 km. The Astrid-2 mission ended on 24 July 1999.
