A Broadband Imaging X-ray All-sky Survey,orABRIXAS,was aspace-basedGermanX-ray telescope.It was launched on 28 April 1999 in aKosmos-3Mlaunch vehicle fromKapustin Yar,Russia,intoEarth orbit.The orbit had aperiapsisof 549.0 kilometres (341.1 mi), anapoapsisof 598.0 kilometres (371.6 mi), aninclinationof 48.0° and aneccentricityof 0.00352, giving it a period of 96 minutes.[3][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.
TheeROSITAtelescope was based on the design of the ABRIXAS observatory.[5]eROSITA was launched on board theSpektr-RGspace observatory on 13 July 2019 fromBaikonurto be deployed at the secondLagrange point(L2).[6]
