The WFIRST study office is managing two technology maturation efforts, for the near infrared (NIR) detectors on the wide field instrument (WFI) and several technologies, including deformable mirrors (DMs), coronagraph masks, and high contrast imaging for the Coronagraph Instrument (CGI). NASA HQ has agreed with the study office on a set of technology milestones for each of these maturation efforts. To date, several milestones have been passed on time and the reports are available here; as additional milestones are met they will be added.
