NASA’s Nancy Grace Roman Space Telescope Is Complete — and May Launch Months Early
NASA’s next flagship observatory has finished assembly under budget and eight months ahead of schedule, with a Falcon Heavy launch now targeted for around September 2026.
NASA’s next great observatory is built, on budget and ahead of schedule — and it could begin scanning the cosmos far sooner than planned.
The short version
- The Nancy Grace Roman Space Telescope finished assembly at NASA’s Goddard center, eight months early and under budget.
- Launch is targeted for around September 2026 on a SpaceX Falcon Heavy, bound for the L2 point ~1 million miles from Earth.
- Its Wide Field Instrument is a 300-megapixel camera with a field of view about 100× Hubble’s.
- Roman surveys the sky roughly 1,000× faster than Hubble and will generate ~500 terabytes of data a year.
- A coronagraph can image planets up to 100 million times fainter than their host stars.
The mission
Roman will probe dark energy and dark matter, hunt for exoplanets and capture transient events such as supernovae across enormous swaths of sky.
Next steps
The observatory now heads to Kennedy Space Center in Florida for final testing, fuelling and launch preparations.
