The Wide-Field Infrared Survey Telescope (WFIRST) is a NASA observatory designed to perform wide-field imaging and slitless spectroscopic surveys of the near infrared (NIR) sky for the community. The current Astrophysics Focused Telescope Assets (AFTA) design of the mission makes use of an existing 2.4m telescope to enhance sensitivity and imaging performance. WFIRST-AFTA will settle essential questions in both exoplanet and dark energy research and will advance topics ranging from galaxy evolution to the study of objects within the Galaxy and within the Solar System. It is the top-ranked large space mission in the New Worlds, New Horizon (NWNH) Decadal Survey of Astronomy and Astrophysics. The main instrument is a wide-field multi-filter NIR imager and spectrometer. With the 2.4m telescope, a coronagraph instrument has been added to the payload for direct imaging of exoplanets and debris disks.
|» Dark Energy
Large area near infrared spectroscopic and imaging surveys at high Galactic latitudes and a Type Ia supernova survey at the ecliptic poles to determine the expansion history of the Universe and the growth history of its largest structures
|» Exoplanets - Microlensing
Photometric survey of the Galactic bulge to complete the statistical census of planets in our Galaxy
|» Exoplanets - Direct Imaging
High contrast imaging and spectroscopic survey of the nearest stars to directly image giant planets and debris disks
|» NIR Sky Survey/Guest Investigator Program
Archival research program using data from the baseline near infrared sky surveys
|» Guest Observer Program
Competitive, peer-reviewed additional science
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.
