On 18 February 2016, NASA announced that Roman had formally become a project (as opposed to a study), meaning that the agency intends to carry out the mission as baselined; at that time, the "AFTA" portion of the name was dropped as only that approach is being pursued. In 2012, another possibility emerged: NASA could use a second-hand National Reconnaissance Office telescope made by Harris Corporation to accomplish a mission like the one planned for Roman.  On 2 March 2020, NASA announced that it had approved Roman to proceed to implementation, with an expected development cost of US$3.2 billion and a maximum total cost of US$3.934 billion including the coronagraph and five years of mission science operations.. 1920x1080 quicktime (2.8 GB) 29.97 fps ProRes version for Video Editors, SubRip caption file (for Facebook and YouTube) (4.0 KB), Nancy Grace Roman Space Telescope 360 spacecraft animations PDR version, Wide-Field Infrared Survey Telescope (WFIRST), Nancy Grace Roman Space Telescope Pumpkin Stencil, OSIRIS-REx Science and Engineering Briefing, Hubble Archive - Servicing Mission 3B, STS-109, Hubble Makes Unexpected Dark Matter Discovery, Dr. John Grunsfeld: NASA Astronaut and Astronomer, How OSIRIS-REx will Steer Itself to Sample an Asteroid. It is intended to achieve a part-per-billion suppression of starlight to enable the detection and spectroscopy of planets as close as 0.15 arcseconds away from their host stars. Roman was recommended in 2010 by United States National Research Council Decadal Survey committee as the top priority for the next decade of astronomy. Scheduled to launch in the mid-2020s, the Nancy Grace Roman Space Telescope, formerly known as WFIRST, will function as Hubble’s wide-eyed cousin. Science support activities for Roman are shared among Space Telescope Science Institute (Baltimore, Maryland), which is the Science Operations Center; the Infrared Processing and Analysis Center, Pasadena, California; and GSFC. The design of the Roman Space Telescope is based on one of the proposed designs for the Joint Dark Energy Mission (JDEM) between NASA and Department of Energy (DOE).
The Nancy Grace Roman Space Telescope is a Hubble-sized telescope targeted for launch in the mid-2020s. GSFC also leads the development of the Wide-Field Instrument, the spacecraft, and the telescope. 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.
 It contained a single instrument, a visible to near-infrared imager/slitless prism spectrometer. The spacecraft is now in design Phase B and is scheduled for launch to L2 in 2025. the Roman Space Telescope CGI will demonstrate the first high-performance coronagraph system in space capable of direct imaging of mature exoplanet systems (such as our own) in reflected starlight, paving the way to a future possible NASA mission aimed at imaging and characterizing faint Earth-like planets. , On 30 November 2018, NASA announced it had awarded a contract for the telescope. Roman is on a plan for a mid-2020s launch. Appendix C documents the disadvantage of L2 versus geosynchronous in the data rate and propellant, but the advantages for improved observing constraints, better thermal stability, and more benign radiation environment at L2. The project is led by a team at NASA's Goddard Space Flight Center in Greenbelt, Maryland. "I knew that taking on this responsibility would mean that I could no longer do research, but the challenge of formulating a program from scratch that I believed would influence astronomy for decades to come was too great to resist," she said in a NASA interview.
The NASA Hubble Space Telescope is a project of international cooperation between NASA and ESA.
NASA hasn’t contracted a launch carrier for the Roman Space Telescope yet, but should name one sometime in 2021. On schedule to launch in the mid-2020s, NASA’s Nancy Grace Roman Space Telescope mission will help uncover some of the biggest mysteries in the cosmos. Roman will also carry a Coronagraph to aid in studying worlds beyond our solar system. The telescope just passed a key milestone review, permitting the team to move on to finalizing the telescope design. The Roman Space Telescope will orbit the L2 Earth-Sun point 750,000 miles beyond Earth’s Moon in a quasi-halo orbit.  A contribution from Germany's Max Planck Institute for Astronomy is under consideration, namely the filter wheels for the star-blocking mask inside the coronagraph.

The newly named Nancy Grace Roman Space Telescope—or Roman Space Telescope, for short—is set to launch in the mid-2020s. It will investigate long-standing astronomical mysteries, such as the force behind the universe’s expansion, and search for distant planets beyond our solar system.  This provided important political momentum to the project, even though the telescope represents only a modest fraction of the cost of the mission and the boundary conditions from the NRO design may push the total cost over that of a fresh design. The detector array is composed of 18 H4RG-10 detectors provided by Teledyne. , In testimony before Congress in July 2018, NASA administrator Jim Bridenstine proposed slowing down the development of Roman in order to accommodate a cost increase in the James Webb Space Telescope (JWST), which would result in decreased funding for Roman in 2020–2021.
The Nancy Grace Roman Space Telescope – or Roman Space Telescope, for short – is set to launch in the mid-2020s. The Nancy Grace Roman Space Telescope (shortened as Roman or the Roman Space Telescope, and formerly the Wide Field Infrared Survey Telescope or WFIRST) is a NASA infrared space telescope currently under development.  The Japanese space agency JAXA is proposing to add a polarization module for the coronagraph, plus a polarization compensator. "Her name deserves a place in the heavens she studied and opened for so many.". Several implementations Roman were studied (including the Joint Dark Energy Mission-Omega configuration, an Interim Design Reference Mission featuring a 1.3 m telescope, Design Reference Mission 1 with a 1.3 m telescope, Design Reference Mission 2, with a 1.1 m telescope, and several iterations of the AFTA 2.4 m configuration). , President Trump's FY2020 budget request, again proposed termination of Roman (then called WFIRST), due to cost overruns and higher priority for JWST.
NRO offered to donate two telescopes, the same size as the Hubble Space Telescope but with a shorter focal length and hence a wider field of view. The newly named Nancy Grace Roman Space Telescope (or Roman Space Telescope, for short), is set to launch in the mid-2020s. Roman first joined NASA in 1959, just months after its creation, and is perhaps best known as the visionary force behind the Hubble Space Telescope, which she helped conceive, plan and advocated for over decades. Watch this video on the NASA Goddard YouTube channel.
 In June 2018, NASA awarded a contract to Teledyne Scientific and Imaging to provide the infrared detectors for the Wide Field Instrument. The Space Telescope Science Institute will serve as the science operations center for the Roman Space Telescope.
The Roman project office is located at NASA's Goddard Space Flight Center in Greenbelt, Maryland, and holds responsibility for overall project management.  In April 2017, NASA commissioned an independent review of the project to ensure that the mission scope and cost were understood and aligned. NASA is currently targeting a launch date for the Roman Space Telescope in October of 2025.  The Roman baseline design includes a coronagraph to enable the direct imaging of exoplanets.. The Roman Space Telescope is based on an existing 2.4 m wide field-of-view primary mirror and will carry two scientific instruments.
 NASA announced the reductions taken in response to this recommendation, and that Roman would proceed to its mission design review in February 2018 and begin Phase B by April 2018. A HgCdTe-based focal-plane array captures a 0.28 square degree field of view with a pixel scale of 110 milliarcseconds. Roman adds some extra capabilities to the original JDEM proposal, including a search for extra-solar planets using gravitational microlensing. Roman was recommended in 2010 by United States National Research Council Decadal Survey committee as the top priority for the next decade of astronomy. The Nancy Grace Roman Space Telescope (shortened as Roman or the Roman Space Telescope, and formerly the Wide Field Infrared Survey Telescope or WFIRST) is a NASA infrared space telescope currently under development.

The Coronagraphic Instrument is a high-contrast, small field-of-view camera and spectrometer covering visible and near-infrared wavelengths using novel starlight-suppression technology.  On 30 November 2018, NASA announced it had awarded the contract for Optical Telescope Assembly to the Harris Corporation of Rochester, New York..  NASA has expressed interest in ESA contributions to the spacecraft, coronagraph and ground station support.  Later, the President announced he had signed the bill 23 March 2018. This is an artist’s illustration of the Nancy Grace Roman Space Telescope spacecraft against a starry background. On 17 February 2016, Roman was approved for development and launch. The Formulation Science Working Group is chaired by the Project scientist, along with Deputy chairs David Spergel and Jeremy Kasdin. It will revolutionize astronomy by building on the science discoveries and technological leaps of the Hubble and James Webb space telescopes. At that time, it was stated that Roman would hold its Preliminary Design Review for the overall mission in October 2019 followed by a formal mission confirmation in early 2020. NASA is currently targeting a launch date for the Roman Space Telescope in October of 2025. Establishing a guest investigator mode, enabling survey investigations to answer diverse questions about our galaxy and the universe. The state-of-the-art telescope on the Roman spacecraft will play a significant role in this, providing the largest picture of the universe ever seen with the same depth and precision as the Hubble Space Telescope. Some science cases (such as exoplanet microlensing parallax) are improved at L2, and the possibility of robotic servicing at either of the locations requires further study.  For the coronagraph instrument, contributions from Europe and Japan are being discussed. Space agencies from four nations and regions, namely Centre National d'Études Spatiales (CNES), German Aerospace Center (DLR), European Space Agency (ESA), and Japan Aerospace Exploration Agency (JAXA) are currently in discussion with NASA to provide various components and science support for Roman. Learn more about the Roman Space Telescope spacecraft with this short tour of the main systems. The Project scientist for Roman from its inception until his death in 2017 was Neil Gehrels, who was succeeded by Jeffrey Kruk, followed in August 2020 by Julie McEnery. The Wide-Field Instrument is a 288-megapixel multi-band near-infrared camera, providing a sharpness of images comparable to that achieved by the Hubble Space Telescope (HST) over a 0.28 square degree field of view, 100 times larger than that of the HST.  These telescopes are 2.4 meters across, about twice as large as the telescope that had been planned for Roman. An accurate polarimetry capability on Roman may strengthen the science case for exoplanets and planetary disks, which shows polarization. Nancy Grace is known as ‘the mother of Hubble’ (the telescope) and worked tirelessly advocating and organizing the Hubble Space Telescope, which has forever changed our view of the universe. The Wide-Field Instrument (WFI) is a 300.8-megapixel camera providing multi-band visible to near-infrared (0.48 to 2.0 micrometers) imaging using one wideband and six narrowband filters.
