description Rossi X-ray Timing Explorer Overview
The Rossi X-ray Timing Explorer (RXTE) was an artificial satellite launched by NASA on December 30, 1995, to observe astronomical X-ray sources. Equipped with three primary instruments, the spacecraft was designed to study the fast timing variability of X-ray emissions from compact objects. This allowed astrophysicists to investigate the extreme gravitational environments surrounding black holes, neutron stars, and X-ray pulsars. The mission was officially decommissioned in January 2012 after over sixteen years of operation.
help Rossi X-ray Timing Explorer FAQ
When was the Rossi X-ray Timing Explorer launched and how long did it operate?
The Rossi X-ray Timing Explorer (RXTE) was launched by NASA on December 30, 1995. It successfully operated in orbit for over 16 years before finally being decommissioned in 2012.
What instruments were used on the Rossi X-ray Timing Explorer?
The spacecraft was equipped with three primary instruments: the Proportional Counter Array (PCA), the High Energy X-ray Timing Experiment (HEXTE), and the All Sky Monitor (ASM). These tools worked together to study the rapid variability of X-ray emissions.
What astronomical objects did the RXTE satellite primarily observe?
RXTE was specifically designed to observe astronomical X-ray sources, focusing heavily on compact objects like neutron stars and black holes. It provided crucial data on kilohertz quasi-periodic oscillations, helping astronomers study extreme gravity.
Why was the RXTE mission named after Bruno Rossi?
The mission was renamed in 1996 to honor Bruno Rossi, a pioneer in X-ray astronomy and cosmic ray physics who passed away in 1993. Originally, the satellite was simply known by the acronym XTE.
