On March 1, a DC to DC converter for the scientific instruments failed, possibly due to a short circuit, ending its scientific mission. However, the satellite was operated until September 27, serving as a testbed for various software algorithms and store-and-forward communications.
The entire satellite was built in a year and the cost, including launch, was 1.4 million U.S. dollars.
Astrid-2edit
Astrid-2 was Sweden's second microsatellite and it was piggybacked with Nadezhda 5, a Russian navigation satellite on December 10, 1998, on a Kosmos-3M rocket from Plesetsk in Russia.[2][3]
Its payload, built by the Swedish Institute of Space Physics in Kiruna and Uppsala and the Royal Institute of Technology (Alfven Laboratory) in Stockholm, was EMMA (Electrical and Magnetic field Monitoring of the Aurora), LINDA (Langmuir INterferometer and Density experiment for Astrid-2), MEDUSA (Miniaturized Electrostatic DUal-tophat Spherical Analyzer) and PIA (Photometers for Imaging the Aurora). It was used to explore the electric and magnetic fields in the upper ionosphere and to measure neutral and charged particles and electron density.
On July 24, 1999, the contact with the satellite was lost. During its 7+1⁄2 months in space, Astrid-2 delivered a large amount of information to researchers.
