Overview
- NASA presented the fully integrated Nancy Grace Roman Space Telescope to media on Tuesday, announcing a September launch and noting the mission is ahead of schedule and under cost.
- After shipment to Kennedy Space Center, a SpaceX Falcon Heavy will lift Roman from Cape Canaveral to a stable orbit near the Sun–Earth L2 point about 1 million miles from Earth.
- Roman uses an eight‑foot mirror and a wide‑field infrared camera to capture Hubble‑like detail across areas about 100 times larger than previous flagship views.
- Planned surveys will map hundreds of millions of galaxies and track Type Ia supernovas to probe dark matter, dark energy, and the rate of the universe’s expansion.
- The mission will scan the Milky Way’s central bulge for gravitational microlensing signals to find thousands of distant or free‑floating planets, and its coronagraph will test technology for future direct imaging of faint worlds.
