A Broadband Imaging X-ray All-sky Survey, or ABRIXAS was a space-based German X-ray telescope. It was launched on 28 April 1999 in a Cosmos launch vehicle from Kapustin Yar, Russia, into Earth orbit. The orbit had a periapsis of 549.0 kilometres (341.1 mi), an apoapsis of 598.0 kilometres (371.6 mi), an inclination of 48.0° and an eccentricity of 0.00352, giving it a period of 96 minutes.
The telescope's battery was accidentally overcharged and destroyed three days after the mission started. When attempts to communicate with the satellite when its solar panels were illuminated by sunlight failed, the $20 million project was abandoned.
