The Rockets for Extended-Source X-ray Spectroscopy (tREXS) are a series of suborbital rocket payloads that fly a diffuse soft X-ray grating spectrometer. The first tREXS was launched in 2022. The spectrometer consists of passive, mechanical focusers, arrays of reflection gratings, and a focal plane consisting of CIS 113 CMOS detectors. The instrument, which has a field-of-view > 10 sq. deg., will seek to obtain the most highly-resolved spectra of diffuse soft X-ray emission from the Cygnus Loop supernova remnant. A future launch will study the Vela supernova remnant.

The Principal Investigator is Dr. McEntaffer/Penn State Univ.
