Abstract

ABRIXAS is a small German satellite project having the goal of surveying the sky in the x-ray band between 0.5 and 12 keV, thereby extending the former ROSAT all-sky survey towards higher energies. It consists of seven highly nested Wolter-I mirror systems which share one common focal plane camera, a CCD detector of the novel pn-type. ABRIXAS benefits from previously developed technologies or existing instruments. ABRIXAS was launched successfully into a low earth orbit by a Russian KOSMOS rocket in late April 1999. A few hours after its launch, however, the mission failed due to a battery problem. Currently, a repetition of the mission is under discussion because both the scientific goal and the mission concept are still be regarded as very attractive.
