The Rossi X-ray Timing Explorer (RXTE) was a satellite that observed the time variation of astronomical X-ray sources, named after physicist Bruno RXTE had three instruments—an All Sky Monitor, the Proportional Counter Array, and the High-Energy X-ray Timing Experiment (HEXTE).

The RXTE observed X-rays from black holes, neutron stars, X-ray pulsars and X-ray date:Decem (UTC). The Rossi X-ray Timing Explorer (RXTE) was launched on Decem from NASA's Kennedy Space Center. The mission was managed and controlled by NASA's Goddard Space Flight Center (GSFC) in Greenbelt, Maryland.

The Rossi X-ray Timing Explorer, RXTE, was launched on Decem RXTE was 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 keV. Near the end of this decade, the X-ray Timing Explorer (XTE) will provide X-ray astronomers with a tool of unprecedented sensitivity for the study of compact X-ray sources.

The principal instruments, a 1 m 2 proportional counter array and a cm 2 phoswich array, will view the sky through coaligned one-degree collimators and provide high sensitivity over a 2 - keV energy range.

The nova's initial X-ray intensity was greater than expected, but the emission faded quickly. Using NASA's Rossi X-ray Timing Explorer, scientists have discovered a limit to how fast a pulsar can spin without destroying itself. Gravitational radiation, ripples in the fabric of space predicted by Albert Einstein, may serve as a cosmic traffic enforcer, protecting reckless pulsars from spinning too fast and blowing apart, according to a report published in the July 3 issue of Nature.
