The SMART-X is a potential successor to this telescope, which itself is a successor to the HEAO observatories and ROSAT.
King et. al. used this device to detect the fastest winds ever recorded around a stellar-mass black hole, at 3% of the speed of light. This device is the main source of data for the Carina Complex Project, which seeks to explain the diffuse emission from the Carina Nebula. The first light image obtained from this device revealed the point source at the center of (*) supernova remnant Cassiopeia A. The SMART-X is a potential successor to this telescope, which itself is a successor to the HEAO observatories and ROSAT. The main focal plane device on this telescope is the ACIS CCD Imaging Spectrometer. This telescope has far superior angular resolution to its European counterpart XMM-Newton, but a lower collecting area. For 10 points, name this satellite which is NASA's main tool for X-ray astronomy.
