NASA's Nancy Grace Roman Space Telescope

Launch Complex 39A - Kennedy Space Center

NET September 2026
The Nancy Grace Roman Space Telescope is a NASA observatory designed to settle essential questions in the areas of dark energy, exoplanets, and infrared astrophysics. Roman’s barrel-like shape will help block out unwanted light from the Sun, Earth, and Moon, and the spacecraft’s distant location will help keep the instruments cool. The telescope has a primary mirror that is 2.4 meters in diameter (7.9 feet) and is the same size as the Hubble Space Telescope's primary mirror. The Roman Space Telescope will have two instruments, the Wide Field Instrument, and the Coronagraph Instrument technology demonstration. While just as sensitive as Hubble's cameras, the Roman Space Telescope's 300-megapixel Wide Field Instrument will image a sky area 100 times larger. This means a single Roman image will hold the equivalent detail of 100 pictures from Hubble. These spacecraft illustrations were created by the NASA Goddard Space Flight Center Scientific Visualization Studio.

ABOUT NANCY GRACE ROMAN SPACE TELESCOPE

Named after NASA’s first chief astronomer, the ‘mother of the Hubble Space Telescope,’ the Nancy Grace Roman Space Telescope will have a field of view at least 100 times larger than Hubble’s, potentially measuring light from a billion galaxies in its lifetime. This observatory will also be able to block starlight to directly see exoplanets and planet-forming disks, complete a statistical census of planetary systems in our galaxy, and settle essential questions in the areas of dark energy, exoplanets, and infrared astrophysics.
