1st High Energy Astrophysics Observatory (HEAO 1. GSFC. NASA)

The first of NASA's three High Energy Astronomy Observatories, HEAO 1 was launched aboard an Atlas Centaur rocket on 12 August 1977 and operated until 9 January 1979. During that time, it scanned the X-ray sky almost three times over 0.2 keV - 10 MeV, provided nearly constant monitoring of X-ray sources near the ecliptic poles, as well as more detailed studies of a number of objects through pointed observations.

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.

BeppoSAX Mission (SAX)

The X-ray astronomy satellite BeppoSAX (Satellite per Astronomia X, "Beppo" in honor of Giuseppe Occhialini) is a project of the Italian Space Agency (ASI) with participation of the Netherlands Agency for Aerospace Programs (NIVR).
In the framework of past and future X-ray missions BeppoSAX stands out for its wide spectral coverage, ranging from 0.1 to over 200 keV. The sensitivity of the scientific payload allows the detailed study over the entire energy band of sources as weak as about 1/20 of 3C273. This opens new perspectives in the study of broad band X-ray spectra and variability of cosmic sources. [also in Italian]

GRB Coordinates Network (GCN)

The GRB Coordinates Network (used to be called BACODINE) system (1) calculates RA,Dec coordinate positions of Gamma Ray Bursts (GRB) detected with BATSE and distributes those positions around the world in real time -- a few seconds! -- so that other instruments can make follow-up observations in other wavebands while the burst is still bursting! (2) distributes locations of GRBs detected by other spacecraft. (3) distributes reports follow-up observations made by ground-based optical and radio observers.
These three functions provide a one-stop shopping network for follow-up sites and GRB researchers.

The group has flown high-energy instruments on Pioneer Venus Orbiter, the ISEE-3 (ICE), P78-1, Vela satellites, and the Japanese satellite Ginga. The group is currently developing experiments for several scientific missions including the X-ray Multimirror Mission (XMM), High Energy Transient Explorer (HETE), MARS-96, and the MOXE all sky x-ray monitor on the Russian Spectrum X-Gamma satellite project, and is the lead institution operating the Array of Low Energy X-ray Imaging Sensors (ALEXIS) satellite and its wide field-of-view ultrasoft x-ray telescope array.
The group is actively participating in Compton Gamma Ray Observatory (CGRO) and Rossi X-ray Timing Explorer (RXTE) research through several guest investigator projects, and is also involved in establishing the growing-up Fenton Hill Observatory in the Jemez mountains, which includes an ultra-high-energy gamma-ray telescope, Milagro.

Two sets of instruments are now under construction: ROTSE-I, a 4-fold camera array using telephoto lenses to cover a 16 degree by 16 degree field of view and ROTSE-II, a pair of 0.45 meter aperture telescopes to cover a 2 degree by 2 degree field of view. The expected sensitivities of these two systems is expected to be m_v ~ 15 and 18 respectively.
