In January of 1993 the Diffuse X-ray Spectrometer (DXS) instruments flew on the STS-54 mission of the Space Shuttle
Endeavour. They collected x-ray spectra of the diffuse soft x-ray background. This dataset will allow us to learn about the region
of space for several hundred light years around the solar system.
The DXS project built the instruments at the University of Wisconsin--Madison Space Science and Engineering Center (SSEC)
in collaboration with Space Physics, and SSEC people were instrumental in every phase of the design, development, testing, flight
operations, and data analysis. Wilt Sanders is the PI, and Bob Paulos is the PM.
