Summary
This is a part of the electronics box from the engineering model for the high-resolution imager (HRI) flown on the ROSAT (Roentgen Satellite) spacecraft. This imager consists of a pair of stacked microchannel plates backed by a grid of crossed wires. This HRI was developed for NASA by the Harvard-Smithsonian Center for Astrophysics. It provided improved sensitivity over an imager used on the earlier Einstein Observatory. ROSAT, named after the discoverer of X-rays, Wilhelm Roentgen, was an international mission aimed at exploring the high-energy universe. It was a cooperative effort between Germany, the United States and Great Britain.
The satellite, which was designed and operated by Germany, was placed in orbit board a Delta II launch vehicle in June 1990. It collected data until February 1999. During that time ROSAT obtained an all sky survey in the X-ray region as well as detailed observations of many galaxies.
The Smithsonian Astrophysical Observatory transferred this object to the Museum in 2002.
