White Sands, New Mexico
FOXSI's third mission, led by Lindsay Glesener of the University of Minnesota, had a successful launch on September 7, 2018 from White Sands, New Mexico. This iteration of the payload included a combination of Silicon and improved Cadmium Telluride detectors, as well as one CMOS soft x-ray detector. Two of the telescope modules were updated from 7-shell to 10-shell configurations, and the payload also introduced collimator technology to reduce the impact of singly-reflected rays.
