The Rossi X-ray Timing Explorer
The Rossi X-ray Timing Explorer, RXTE, was launched on December 30, 1995. RXTE is designed to facilitate the study of time variability in the emission of X-ray sources with moderate spectral resolution. Time scales from microseconds to months are covered in a broad spectral range from 2 to 250 keV. It is designed for a required lifetime of two years, with a goal of five years.
