The Swift Gamma-Ray Burst Explorer will be launched late in 2003 to make prompt multiwavelength observations of Gamma-Ray Bursts and Afterglows. The X-ray Telescope (XRT) provides key capabilities that permit Swift to determine GRB positions with several arcsecond accuracy within 100 seconds of the burst onset.

The Solar X-ray Imager (SXI) is a complimentary, add-on instrument designed for use on the next generation of Geostationary Orbiting Environmental Satellites (GOES). Its primary mission is to continuously observe the full solar disc at X-ray wavelengths; including coronal holes, active regions, flares, and coronal mass ejections. For wide-field imaging

Hadamard X-ray Spectro-telescope
Advances in Space Research, 1982Abstract The Hadamard X-ray Spectro-telescope consists of a flat Bragg crystal, an Hadamard mask and an imaging proportional counter. We have achieved α⧸▵α≈50, which is limited by the position resolution of the detector. This telescope is useful to observe the spectral structure of extended X-ray sources.

NeXT is Japan's 6th X-ray astronomical observatory following to ASTRO-E2. The launch is currently scheduled in 2010. One of the main goal of NeXT is to explore the hard X-ray Universe with newly developed hard X-ray telescope. The hard X-ray telescope utilizes multilayer-supermirror and high-throughput thin-foil optics technology.

Goldhelox: A Soft X-Ray Solar Telescope
Journal of X-Ray Science and Technology, 1995The Goldhelox Project is the construction and use of a near-normal incidence soft x-ray robotic solar telescope by undergraduate students at Brigham Young University. Once it is completed and tested, it will be deployed from a Get-Away-Special (GAS) canister in the bay of a space shuttle.

Equal-curvature grazing-incidence x-ray telescopes
Applied Optics, 2003We introduce a new type of x-ray telescope design, an equal-curvature telescope. We simply add a second-order axial sag to the base grazing-incidence cone-cone telescope. The radius of curvature of the sag terms is the same on the primary surface and on the secondary surface.

Orthogonal Mirror Telescopes for X-ray Astronomy
Applied Optics, 1971Crossed mirror telescopes are presented as an alternative to the present telescope systems used in x-ray astronomy. These instruments generally have a higher x-ray collecting efficiency but a poorer angular resolution than the more conventional paraboloid-hyperboloid telescopes.

The X-Ray Imaging Telescopes on EXOSAT
Space Science Reviews, 1981The instrument configuration and performance characteristics of the X-ray imaging telescopes on EXOSAT are described. The instrument comprises two fully independent Wolter I imaging telescopes. Each telescope can be used in either of two principal modes: (i) an imaging mode with either a position sensitive proportional counter or a channel multiplier ...

Operation of the x-ray telescope eROSITA
SPIE Proceedings, 2010The X-ray telescope eROSITA is the core instrument besides the Russian ART-XC on the Russian Spektrum-Roentgen- Gamma satellite which will be launched in 2012 to an orbit around the L2 point of the Earth-Sun-system. During both survey and pointing phase the solar panels and the antenna constrain the possible mission scenario.
