Array of Low Energy X-ray Imaging Sensors (ALEXIS)

ALEXIS' X-ray telescopes feature curved mirrors whose multilayer coatings reflect and focus low-energy X-rays or extreme ultraviolet light the way optical telescopes focus visible light. The satellite and payloads were funded by the Department of Energy and built by Los Alamos National Laboratory in collaboration with Sandia National Laboratory and the University of California-Space Sciences Lab. The Launch was provided by the Air Force Space Test Program on a Pegasus Booster on April 25, 1993. The mission is entirely controlled from a small groundstation at LANL.

Astronomical Data Center (ADC)

The Astronomical Data Center (ADC), at NASA Goddard Space Flight Center, Greenbelt, Maryland, is a cooperative effort between the National Space Science Data Center (NSSDC)/ World Data Center A for Rockets and Satellites (WDC-A-R&S) and its parent organization, the Space Science Data Operations Office . Currently, the ADC archives hold more than 670 catalogs of astrometry, photometry, spectroscopy, radio, and other miscellaneous data for stellar and nonstellar objects. The data were acquired through exchanges with the Centre de Donn'ees Astronomiques de Strasbourg (CDS) , other astronomical data centers throughout the world, and by direct contributions from the international astronomical community.

Atomic Line List

The atomic line list is a compilation of approximately 855,000 allowed, intercombination and forbidden atomic transitions with wavelengths in the range from 0.5 Å to 1000 µm. Its primary intention is to allow the identification of observed atomic absorption or emission features. The list is nearly complete for all ionization stages of all elements up to zinc. Transition probabilities are available for nearly 14% of the lines; they are mostly derived from Opacity Project data.

INACTIVE LINK ? - 94 --- German Interferometer for Multi-channel Photometry and Astrometry (DIVA)

The Deutsches Interferometer fuer Vielkanalphotometrie und Astrometrie (DIVA) is a small astronomy satellite, planned for launch in 2004. It is aimed to measure positions, proper motions and parallaxes, brightness and color of at least 30 million stars.

Hubble Space Telescope (HST)

The Hubble Space Telescope is a cooperative program of the European Space Agency (ESA) and the National Aeronautics and Space Administration (NASA) to operate a long-lived space-based observatory for the benefit of the international astronomical community. To accomplish this goal and protect the spacecraft against instrument and equipment failures, NASA had always planned on regular servicing missions. Hubble has special grapple fixtures, 76 handholds, and stabilized in all three axes. HST is a 2.4-meter reflecting telescope which was deployed in low-Earth orbit (600 kilometers) by the crew of the space shuttle Discovery (STS-31) on 25 April 1990. HST's current complement of science instruments include three cameras, two spectrographs, and fine guidance sensors (primarily used for astrometric observations). Because of HST's location above the Earth's atmosphere, these science instruments can produce high resolution images of astronomical objects. Ground-based telescopes can seldom provide resolution better than 1.0 arc-seconds, except momentarily under the very best observing conditions. HST's resolution is about 10 times better, or 0.1 arc-seconds.

Large Binocular Telescope Observatory (LBT)

The Large Binocular Telescope (LBT) is a collaboration between Arizona (25%), Italy (25%, represented by the Arcetri Astrophysical Observatory in Florence), Research Corporation (12.5%), the Ohio State University (12.5%), and Germany (25%, represented by the LBT Beteiligungsgesellschaft).
The goal of the LBT project is to construct and exploit a binocular telescope consisting of two 8.4-meter mirrors on a common mount. This telescope will be equivalent in light-gathering power to a single 11.8-meter instrument. Because of its binocular arrangement, the telescope will have a resolving power (ultimate image sharpness) corresponding to a 23-meter telescope.
