This site presents the work of the Space Telescope Science Institute (STScI) on the WFIRST mission, which presently includes concept and requirements development for the mission's observation scheduling system, wide-field imaging data processing system, and the data archive, development of data simulation tools, and engaging the astronomical community in the mission science. Links to specific subjects, software, and reports can be found in the menu on the left.
A Wide Field Infra-Red Survey Telescope (WFIRST) was the top large space priority in the report of the ASTRO2010 Decadal Survey "New Worlds, New Horizons in Astronomy and Astrophysics". NASA will implement the WFIRST program on a 2.4m AFTA (Astrophysics-Focused Telescope Assets) telescope, donated to NASA by the another agency. Please check out the mission's latest news and news pages maintained by our partners.
The Design Reference Mission in the Final Report of the WFIRST-AFTA Science Definition Team describes an ambitious science program. This includes a multi-pronged approach to measuring dark energy, the discovery and census of planets down to sub-Earth masses via their microlensing signatures, and the imaging and spectroscopy of planets via coronagraphy. Moreover, the WFIRST instruments will enable many exciting studies in General Astrophysics, through the combination of Guest Observer programs and archival Guest Investigator studies of the wide-area and time-resolved WFIRST surveys.
This brochure describes how the HST, JWST, and WFIRST space telescopes provide the complementary and synergistic optical/infrared observing capabilities needed to continue to transform our view of the Universe in the 2020's. Appendix B of the Final Report of the WFIRST-AFTA Science Definition Team describes a number of specific science programs that can exploit WFIRST and JWST synergies.
The WFIRST mission is currently in the NASA formulation phase and involves work by various institutions. The WFIRST Project Office is at Goddard Space Flight Center (GSFC), which also oversees the work on the Wide Field Imager instrument, the Spacecraft Bus, and System Integration. The Jet Propulsion Laboratory (JPL) oversees the work on the coronagraphic instrument and the telescope. STScI is a partner in the WFIRST science center, sharing science operations responsibilities with the Infrared Processing and Analysis Center (IPAC) and GSFC. STScI leads the work on the mission's observation scheduling system, wide-field imaging data processing system, and the data archive. A Formulation Science Working Group, Science Investigation Teams, a Preparatory Science Team, and previously a Science Definition Team help prepare the mission science. Links to the web pages of the various mission partners can be found in the menu on the right.
