Quick answers

Where is the Roman Space Telescope right now?
About 1,499,456 km from Earth as of 18 Oct 2026, 100% of the way to Sun–Earth L2 (1,501,000 km out), per the JPL Horizons ephemeris. It is coasting and slowing, now at 0.24 km/s relative to Earth. Live position →
When will Roman's first images be released?
Roman's first photons, an unfocused engineering test image, came on 15 Sept 2026. NASA expects science images by early 2027, after the telescope is aligned, focused and calibrated. See the first-photons image →
When did Roman launch?
30 Aug 2026 at 11:26 UTC (7:26 a.m. EDT), on a Falcon Heavy from Kennedy Space Center, LC-39A. Confirmed milestones since launch →
When does Roman reach L2?
NASA puts orbit insertion at about 100 days after launch, around 08 Dec 2026. Commissioning (cooling, focusing and checking out the instruments) runs in parallel. Commissioning timeline →
Where will Roman's data be published?
At MAST, the Mikulski Archive for Space Telescopes at STScI. Roman survey data has no proprietary period, so it is public as soon as it is processed. What it will observe →
