Jan. 25, 2021 - When it launches in the mid-2020s, NASA’s Nancy Grace Roman Space Telescope will explore an expansive range of infrared astrophysics topics. One eagerly anticipated survey will use a gravitational effect called microlensing to reveal thousands of worlds that are similar to the planets in our solar system. Now, a new study shows that the same survey will also unveil more extreme planets and planet-like bodies in the heart of the Milky Way galaxy, thanks to their gravitational tug on the stars they orbit.
Jan. 11, 2021 - Roman will be able to photograph an area of the sky at least 100 times larger than Hubble with the same crisp sharpness. Among the many observations that will be enabled by this wide view of the cosmos, astronomers are considering the possibility and scientific potential of a Roman Space Telescope "ultra-deep field." Such an observation could reveal new insights into subjects ranging from star formation during the universe’s youth to the way galaxies cluster together in space.
Nov. 18, 2020 - Roman will detect vestiges of sound waves that once rippled through the primordial cosmic sea. According to new simulations, these observations could extend these measurements into an unprobed epoch between the universe’s infancy and the present day. Studying the echoes from this era will help us trace the evolution of the universe and solve pressing cosmic conundrums.
Sept. 3, 2020 - The Nancy Grace Roman Space Telescope’s primary mirror, which will collect and focus light from cosmic objects near and far, has been completed. Using this mirror, Roman will capture stunning space vistas with a field of view 100 times greater than Hubble images.
Aug. 21, 2020 - New simulations show that NASA’s Nancy Grace Roman Space Telescope will be able to reveal myriad rogue planets – freely floating bodies that drift through our galaxy untethered to a star. Studying these island worlds will help us understand more about how planetary systems form, evolve, and break apart.
July 24, 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.
Previous news releases will refer to the mission as WFIRST
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.
March 30, 2020 - WFIRST will search for planets outside our solar system toward the center of our Milky Way galaxy, where most stars are. Studying the properties of exoplanet worlds will help us understand what planetary systems throughout the galaxy are like and how planets form and evolve.
Jan. 7, 2020 - Disagreement between Hubble constant predictions and measurements suggest flaws in either our measuring techniques or our model of the universe. The Roman Space Telescope will help us figure out which.
Jan. 5, 2020 - Imagine a fleet of 100 Hubble Space Telescopes, deployed in a strategic space-invader-shaped array a million miles from Earth, scanning the universe at warp speed.
Jan. 5, 2020 - An international team of astronomers funded in part by NASA has found the farthest galaxy group identified to date.
Oct. 31, 2019 - WFIRST’s ability to survey wide swaths of the universe will help us figure out what dark matter could be made of by exploring the structure and distribution of both matter and dark matter across space and time.
Sept. 24, 2019 - When a new NASA space telescope opens its eyes in the mid-2020s, it will peer at the universe through some of the most sophisticated sunglasses ever designed.
Sept. 13, 2019 - NASA's Wide Field Infrared Survey Telescope will explore how dark energy has affected the universe's expansion in the past, which will let us foresee its possible fate.
Aug. 28, 2019 - On schedule to launch in the mid-2020s, NASA’s Wide Field Infrared Survey Telescope (WFIRST) will help uncover some of the biggest mysteries in the cosmos.
Aug. 6, 2019 - Jody Davis, the Deputy Payload Systems Engineer on WFIRST, inspires Davis to inspire others--and she does.
June 26, 2019 - To know how the universe will end, we must know what has happened to it so far. This is just one mystery NASA's forthcoming Wide Field Infrared Survey Telescope (WFIRST) mission will tackle as it explores the distant cosmos. WFIRST's giant camera, the WFI, will be fundamental to this exploration, and it has just passed an important milestone.
Nov. 30, 2018 - NASA has awarded a contract to Harris Corporation of Rochester, New York, for the Optical Telescope Assembly (OTA) for the agency’s Wide Field Infrared Survey Telescope (WFIRST) mission.
June 15, 2018 - NASA has awarded a contract to Teledyne Scientific & Imaging, LLC, Camarillo, California, for the Short Wave Infra-Red Sensor Chip Assembly (SCA) for the Wide Field Infrared Survey Telescope (WFIRST) Project.
May 2018 : WFIRST passed a key project milestone, clearing it to enter its preliminary design phase and begin major procurements for flight hardware. The mission completed a series of critical reviews indicating the project is on track to enter the next development phase and meet its scientific goals within its budget of $3.2 billion.
May 23, 2018 : NASA has awarded a contract to Ball Aerospace and Technologies Corporation, Boulder, Colorado, for the primary instrument components for the Wide Field Infrared Survey Telescope (WFIRST).

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.
