The Nancy Grace Roman Space Telescope will settle essential questions in the areas of dark energy, exoplanets, and astrophysics.

Future Mission

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.

Type

Space Telescope

Launch

By May 2027

Target

Universe, Exoplanets

Objective

Settle essential questions in the areas of dark energy, exoplanets, and astrophysics
In September 2024, the Nancy Grace Roman Space Telescope passed a key milestone and was approved for the next stage of construction. Work on the main systems that will make up the final spacecraft is finishing, and the team at NASA’s Goddard Space Flight Center is ready to begin integration, the process of connecting them together. This video celebrates the effort to reach the final stages of assembly.
