The Chandra X-ray Observatory (CXO), previously known as the Advanced X-ray Astrophysics Facility (AXAF), is a Flagship-class space telescope launched aboard the Space Shuttle Columbia during STS-93 by NASA on July 23, 1999.
Creator/Photographer: Chandra X-ray Observatory NASA's Chandra X-ray Observatory, which was launched and deployed by Space Shuttle Columbia on July 23, 1999, is the most sophisticated X-ray observatory built to date. The mirrors on Chandra are the largest, most precisely shaped and aligned, and smoothest mirrors ever constructed.
The Chandra X-ray Observatory marked its 25th anniversary with a release of never-before-seen images. But budget cuts may cause the observatory’s days to be numbered.
AXAF was renamed Chandra X-ray Observatory in 1998. It was launched July 23, 1999, by the Shuttle Columbia (STS-93). An Inertial Upper Stage booster adapted by MSFC was used to transport Chandra to its high orbit Weighing about 22,700 kg (50,000 lb), this was the heaviest payload ever launched by a Shuttle. Operationally managed by the SAO ...
Chandra's large size, high orbit, and sensitive CCDs allowed observations of very faint X-ray sources. Spitzer also observes at wavelength largely inaccessible to ground telescopes. It was preceded in space by NASA's smaller IRAS mission and European Space Agency (ESA)'s large ISO telescope. Spitzer's instruments took advantage of the rapid ...
The principal investigator is Martin C. Weisskopf of NASA Marshall Space Flight Center; he is the chief scientist for X-ray astronomy at NASA's Marshall Space Flight Center and project scientist for the Chandra X-ray Observatory spacecraft. [7]
The primary objective of the STS-93 mission was to deploy the Chandra X-ray Observatory (formerly the Advanced X-ray Astrophysics Facility) with its Inertial Upper Stage booster. At its launch, Chandra was the most sophisticated X-ray observatory ever built. It is designed to observe X-rays from high energy regions of the universe, such as hot ...
