List of X-ray space telescopes

X-ray telescopes are designed to observe the x-ray region of the electromagnetic spectrum. X-rays from outer space cannot be observed from the ground due to absorption by the atmosphere, and so x-ray telescopes must be launched into orbit. Their mirrors require a very low angle of reflection (typically 10 arc-minutes to 2 degrees).[1] These are called glancing (or grazing) incidence mirrors. In 1952, Hans Wolter outlined three ways a telescope could be built using only this kind of mirror.[2][3]

Space-borne observatories and instrumentsEdit

This list contains space-borne observatories as well as X-ray instruments as part of a larger mission, both past, present and in the proposal stage.

High-altitude atmospheric observatories and instrumentsEdit

Sometimes X-Ray observations are made from a near-space environment on sounding rockets or high-altitude balloons.
