NASAโ€™s Goddard Space Flight Center, Greenbelt, Md., intends to award a sole-source contract to Teledyne Scientific & Imaging of Camarillo, Calif., for a dozen sensor chip assemblies for the Wide-Field Infrared Survey Telescope (WFIRST) project, according to a Nov. 16 announcement on the Federal Business Opportunities procurement website.

NASA is looking at two mission concepts for WFIRST, a proposed infrared space observatory that ranked first in the National Research Councilโ€™s most recent decadal survey of the science communityโ€™s astronomy and astrophysics priorities.

Both concepts are based on test results from a detector module subassembly built for the Joint Dark Energy Mission, a since-abandoned NASA undertaking with the U.S. Department of Energy that served as the basis for WFIRST concept.

NASA wants to buy 12 additional sensor chip assemblies โ€” specifically, the H4RG-10 โ€” from Teledyne Scientific & Imaging for Goddardโ€™s Detector Characterization Laboratory to use for testing and to be incorporated into a focal plane assembly for a WFIRST engineering development unit. NASA would expect delivery of the sensor chip assemblies within 36 months of contract.
