Introducing
the
Nancy Grace Roman
Space Telescope

Slide Background

The Roman Space Telescope is a NASA observatory designed to settle essential questions in the areas of dark energy, exoplanets, and infrared astrophysics.

The Roman Space Telescope will use a technique called coronagraphy to block the glaring light of exoplanet host stars to directly see planets and planet-forming disks. The Coronagraph Instrument is an advanced technology demonstrator for future exoplanet missions.

About the Mission

The Roman Space Telescope is a NASA observatory designed to unravel the secrets of dark energy and dark matter, search for and image exoplanets, and explore many topics in infrared astrophysics.

  • The Roman Space Telescope has a 2.4m telescope, the same size as Hubble’s, but with a view 100 times greater than Hubble’s.
  • The Roman Space Telescope was the top-ranked large space mission in the 2010 Decadal Survey of Astronomy and Astrophysics.
  • The Roman Space Telescope is slated to launch in the mid-2020s.
  • The Roman Space Telescope will have no proprietary data period and all observing time will be competed.
