Chandra X-Ray Observatory
The MST was also responsible for the ground calibration of the HRMA at the X-ray Calibration Facility (XRCF) at the Marshall Space Flight Center in Huntsville, Alabama.
Currently I work on the calibration of the Chandra X-ray Observatory (CXO) as part of the CXC Calibration group. Here is a schematic of the observatory. Some of our work on CXO mirror calibration is described here
The ground calibration and the on-orbit calibration are being used to refine a high-fidelity raytrace model of the CXO performance.
After two scrubbed launch attempts, Chandra was successfully launched 1999 July 23, 12:31AM EDT, as part of space shuttle mission STS-93.
