Nancy Grace Roman Space Telescope

The Nancy Grace Roman Space Telescope is a NASA infrared space telescope that was launched on a trajectory toward a Sun–Earth L2 orbit on 30 August 2026. It is named after NASA's first chief of astronomy, Nancy Grace Roman. The telescope is based on an existing 2.4-meter (7.9-foot) primary mirror with a wide field of view that was donated by the National Reconnaissance Office and will carry two scientific instruments. The Wide-Field Instrument (WFI) is a 300.8-megapixel multi-band visible and near-infrared camera, providing image sharpness comparable to the Hubble Space Telescope over a 0.28-square-degree field of view, 100 times larger than imaging cameras on the Hubble. The Coronagraph Instrument (CGI) is a high-contrast, small-field-of-view camera and spectrometer covering visible and near-infrared wavelengths using novel starlight-suppression technology. Its objectives include a search for exoplanets using gravitational microlensing, along with probing the chronology of the universe and growth of cosmic structure, with the end goal of measuring the effects of dark energy, the consistency of general relativity, and the curvature of spacetime. Roman was recommended in 2010 by the United States National Research Council Decadal Survey committee as the top priority for the next decade of astronomy. It was approved for development and launch on 17 February 2016. NASA expects to release Roman's first science images by early 2027.

The original design, called WFIRST (Wide-Field Infrared Survey Telescope) Design Reference Mission 1, was studied in 2011–2012, featuring a 1.3-meter (4 ft 3 in) diameter unobstructed three-mirror anastigmat telescope. It contained a single instrument, a visible to near-infrared imager/slitless prism spectrometer.

• Roman Space Telescope

  Named for Nancy Grace Roman, the Roman Space Telescope (formerly, the Wide Field InfraRed Survey Telescope, or WFIRST) is a NASA observatory designed to settle essential questions in the areas of dark energy, exoplanets and infrared astrophysics. The telescope has a primary mirror that is 2.4 meters (7.9 feet) in diameter and is the same size as the Hubble Space Telescope's primary mirror. The Roman Space Telescope is designed to have two instruments, the Wide Field Instrument and a technology demonstration Coronagraph Instrument. The Wide Field Instrument will have a field of view that is 100 times greater than the Hubble infrared instrument, allowing it to capture more of the sky with less observing time. The Coronagraph Instrument will perform high contrast imaging and spectroscopy of

  # Introduction The Nancy Grace Roman Space Telescope is a NASA space telescope that observes at visible and infrared wavelengths and is designed to tackle questions in the areas of dark energy, exoplanets, and general astrophysics. Roman has a primary mirror that is 2.4 meters in diameter (the same size as Hubble's) and has two instruments, the Wide Field Instrument and the Coronagraph Instrument. The Wide Field Instrument is the main survey instrument having a field of view 200 times larger than Hubble's infrared view. Roman is slated to launch no later than May 2027, with the team working toward a potential early launch as soon as September 2026. Science Payload [...] Roman User Documentation Close Menu Menu Navigation Home Roman Proposals Home Cycle 1 Call for Proposals Mission Overview # Mission Overview This section briefly summarizes the scientific capabilities of the Nancy Grace Roman Space Telescope. Note: The content of the Call represents the known ground characterization of the observatory performance through October 2025. It is anticipated that improved and/or additional technical performance specifications will be available over the next few months, pending analysis of data obtained during integration and testing of the Roman hardware.

The Nancy Grace Roman Space Telescope is a Hubble-sized telescope that will revolutionize astronomy by building on the science discoveries and technological leaps of the Hubble and James Webb space telescopes. Roman launched on August 30, 2026. [...] Roman will provide a panoramic field of view that is 200 times greater than Hubble's infrared view, leading to the first wide-field maps of the universe at space-based resolution. Roman will combine the power of imaging and spectroscopy in synergy with other observatories to gain fresh insights into the universe through focused surveys and General Astrophysics observations. Using a wide field instrument, Roman will survey billions of galaxies and catch the light of stellar explosions in a quest to solve the mystery of dark energy, which is causing the universe’s expansion to speed up. Roman’s scans of the sky will uncover thousands of exoplanets beyond our solar system, including types of planets never surveyed before. [...] An observation (labeled “VISTA V V V Survey, Near-infrared) of the Milky Way’s center pointing toward its supermassive black hole, which is labeled Sagittarius A (pronounced “A star”). At 7 o’clock from center is a small region, outlined with 5 fields of view from the Nancy Grace Roman Space Telescope that are stacked together in a horizontal rectangle. This region is about a third of the image in length and a fifth of the image in width. Within that same region are diagonal lines that alternate between orange and blue. A legend at the bottom left shows two Hubble instruments. One of them, marked with an orange diamond, is labeled “W F C 3 / U V I S.” The other, marked with a blue diamond, is labeled “A C S / W F C.” The background is a field of stars, gas, and dust that appear grey,
