The Chandra X-Ray Observatory, the x-ray component of NASA's Great Observatories, was launched early in the morning of 1999, July 23 by the Space Shuttle Columbia. The Shuttle launch was only the first step in placing the observatory in orbit. After release from the cargo bay, the Inertial Upper Stage performed two firings, and separated from the observatory as planned. Finally, after five firings of Chandra's own Integral Propulsion System--the last of which took place 15 days after launch… 
Managing radiation degradation of CCDs on the Chandra X-ray Observatory
The CCDs on the Chandra X-ray Observatory are sensitive to radiation damage, particularly from low-energy protons scattering off the telescope's mirrors onto the focal plane. In its highly elliptical
The evolution of the ACIS contamination layer over the 16-year mission of the Chandra X-ray Observatory
The Chandra X-ray Observatory (CXO) was launched 16 years ago and has been delivering spectacular science over the course of its mission. The Advanced CCD Imager Spectrometer (ACIS) is the prime
X-ray observations of PSR B1259−63 near the 2007 periastron passage
PSR B1259‐63 is a 48 ms radio pulsar in a highly eccentric 3.4 year orbit with a Be star SS 2883. Unpulsedγ-ray, X-ray and radio emission components are observed from the binary system. It is likely
Toward active x-ray telescopes II
In the half century since the initial discovery of an astronomical (non-solar) x-ray source, the observation time required to achieve a given sensitivity has decreased by eight orders of magnitude.
Pre-flight evaluation of the soft X-ray telescope optics aboard AstroSat
Soft X-ray telescope (SXT) built on the principle of grazing incidence optics was launched on-board AstroSat on September 28, 2015, and made operational on October 26, 2015. The telescope optics

The Lynx architecture enables a broad range of unique and compelling science to be carried out mainly through a General Observer Program, envisioned to include detecting the very first seed black holes, revealing the high-energy drivers of galaxy formation and evolution, and characterizing the mechanisms that govern stellar evolution and stellar ecosystems.
The spectacular ii —rst light ˇˇ observation by the Chandra X-Ray Observatory revealed an X-ray point source near the center of the 300 yr old Cas A supernova remnant. We present an analysis of the
Grazing incidence telescopes for x-ray astronomy
With grazing incidence telescopes, x-ray astronomy became a major branch of astrophysics. They are an indispensable tool in the study of >10 6 K thermal and non-thermal high energy phenomena
Chandra Observations of the X-Ray Jet in Centaurus A
We present high angular resolution X-ray images and spectra from two Chandra AXAF CCD Imaging Spectrometer (ACIS-I) observations of the X-ray jet in the nearby radio galaxy Cen A. We find that the


Absolute effective area of the Chandra high-resolution mirror assembly (HRMA)
The Chandra X-ray Observatory was launched in July 1999, and is returning exquisite sub-arc second X-ray images of star groups, supernova remnants, galaxies, quasars, and clusters of galaxies. In
Orbital verification of the CXO high-resolution mirror assembly alignment and vignetting
Prior to launch, the High Resolution Mirror Assembly (HRMA) of the Chandra X-ray Observatory underwent extensive ground testing at the X-ray Calibration Facility (XRCF) at the Marshall Space Flight
Measurements with the Chandra X-ray Observatory's flight contamination monitor
NASA's Chandra X-ray Observatory includes a Flight Contamination Monitor (FCM), a system of 16 radioactive calibration sources mounted to the inside of the Observatory's forward contamination cover.
Calibration of the AXAF observatory: overview
The Advanced X-ray Astrophysics Facility (AXAF) will soon begin its exploration of the x-ray universe, providing unprecedented angular and spectral resolution. Also unprecedented is the ambitious
Performance expectation versus reality
The AXAF (Advanced X-ray Astrophysics Facility) high resolution mirror assembly (HRMA) now is complete and has been tested at the NASA Marshall Space Flight Center (MSFC) X-ray Calibration Facility
Focus and alignment of the AXAF optics
The x-ray measurement of the focus and alignment of the AXAF (Advanced X-ray Astrophysics Facility) x-Ray optics is discussed and a preliminary model for the relative location and rigid-body orientation of the individual mirror elements is developed.
Initial performance of the aspect system on the Chandra Observatory: postfacto aspect reconstruction
The aspect system of the Chandra Observatory plays a key role in realizing the full potential of Chandra's X-ray optics and detectors. To achieve the highest spatial and spectral resolution (for
Radiation damage in the Chandra x-ray CCDs
Front side illuminated CCDs comprising focal plane of Chandra X-ray telescope have suffered some radiation damage in the beginning of the mission. Measurements of CTI and dark current at different
Advanced X-ray Astrophysics Facility (AXAF): calibration overview
The AXAF, the x-ray component of NASA's great observatories, will launch in 1999. As integration and testing of the flight system are concluding, analysis of the ground calibration data continues.
A First Look at the Nuclear Region of M31 with Chandra
We report on the first observation of the nuclear region of M31 with the Chandra X-Ray Observatory. The nuclear source seen with the Einstein and ROSAT HRIs is resolved into five point sources. One
