36.292 UH Terrier-Black Brant was launched from White Sands Missile Range, NM on May 2, 2015. The OGRESS instruments provided high spectral resolving power for large diffuse X-ray sources. The science target was the Cygnus Loop supernova remnant which is one of the brightest and largest soft X-ray emitters in the sky. The observation provided global plasma conditions from this object which are typified by interactions between the supernova blast wave and a precursor formed cavity wall. The payload also contains a critical NASA X-ray technology ― off-plane reflection grating arrays. Combined with parallel technology development efforts, this mission will provide a flight proving platform for future X-ray missions. The Principal Investigator is Dr. Randall McEntaffer/University of Iowa.
