Overview
- NASA set the Nancy Grace Roman Space Telescope to lift off on Aug. 30, 2026, aboard a SpaceX Falcon Heavy from Kennedy Space Center and has begun final vehicle integration and encapsulation.
- The team completed hydrazine fueling and says the project is nine months ahead of its formal readiness schedule after extensive mission‑readiness tests.
- Roman will coast to the Sun–Earth L2 point about one million miles away, complete commissioning roughly 100 days after launch, and begin a planned five‑year primary survey.
- The observatory uses a 2.4‑meter mirror with a Wide Field Instrument that images areas about 100 times wider than Hubble’s view and carries a coronagraph to demonstrate direct exoplanet imaging technology.
- Roman is designed to downlink roughly 1 terabyte of science data per day to support surveys that will map billions of galaxies, probe dark matter and dark energy, and deliver a large census of exoplanets while complementing JWST and Rubin Observatory science.
