Celebrating the 10th Anniversary of the
Chandra X-Ray Observatory


On July 23, 1999, NASA's Chandra X-ray Observatory, was launched and deployed by Space Shuttle Columbia's STS-93 mission. Today, Chandra is still the most sophisticated X-ray observatory built to date, and one of NASA's four great observatories.

ITT Space Systems Division was contracted to build the X-ray telescope for the satellite. ITT designed, assembled, aligned and tested the Optical Bench Assembly (OBA), the backbone of the telescope, and the High Resolution Mirror Assembly (HRMA), the heart of the telescope. The HRMA, which contains eight mirrors — the largest of their kind and the smoothest ever created — was the most complicated and most crucial component of Chandra.

Chandra was specially designed to detect X-ray emission from very hot regions of the universe such as exploded stars, clusters of galaxies, and matter around black holes, and is giving astronomers unprecedented information about our universe, captured with the help of ITT's precision components.
