The Administrator directed the Science Mission Directorate to continue pre-formulation activities for the WFIRST mission. The Astrophysics Focused Telescope Assets (AFTA) Science definition team (SDT) study office begin developing telescope design.
Instruments are announced
Two WFIRST-AFTA Instruments announced. Wide-Field Instrument and Coronograph
Formulation Science Investigation Teams
NASA announced on December 17, 2015 the selection of the following Formulation Science Investigation Teams for the WFIRST mission. These teams will work for 5 years with the NASA and Project teams on science requirements, mission design and scientific performance predictions for the mission.

Preliminary Design Review
Aug. 28, 2019
The telescope for WFIRST has successfully passed its preliminary design review, a major milestone for the mission. This means the telescope has met the performance, schedule, and budget requirements to advance to the next stage of development, where the team will finalize its design.
Mission Renamed to Nancy Grace Roman Telescope
May 20, 2020
NASA is naming its next-generation space telescope currently under development, the Wide Field Infrared Survey Telescope (WFIRST), in honor of Nancy Grace Roman, NASA’s first chief astronomer, who paved the way for space telescopes focused on the broader universe.
Ground System Completes Major Review
July 24, 2020
"This is an exciting milestone for the mission,” said Ken Carpenter, the Roman ground system project scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “We are on track to complete the data system in time for launch, and we look forward to the ground-breaking science it will enable."
Primary Mirror Completed
Sept. 3, 2020
The Roman mission’s ground system, which will make data from the spacecraft available to scientists and the public, has just successfully completed its preliminary design review. The plan for science operations has met all of the design, schedule, and budget requirements, and will now proceed to the next phase: building the newly designed data system.
