A Broadband Imaging X-ray All-sky Survey, or ABRIXAS, was a space-based Germany X-ray telescope. It was launched on 28 April 1999 in a Kosmos-3M 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.[2][3]

The telescope's battery was accidentally overcharged and destroyed three days after the mission started. When attempts to communicate with the satellite — while its solar panels were illuminated by sunlight — failed, the $20 million project was abandoned.[4] ABRIXAS decayed from orbit on 31 October 2017.

The eROSITA telescope is based on the design of the ABRIXAS observatory.[5] eROSITA was launched on board the Spektr-RG space observatory on 13 July 2019 from Baikonur to be deployed at the second Lagrange point (L2).[6]
