Roman Space Telescope Begins Transit to L2 After Successful Falcon Heavy Launch

The coronagraph is powered on for months of calibration and the mission will deliver large, open data streams that aim to transform studies of dark matter, dark energy and exoplanets.

A SpaceX Falcon Heavy rocket carrying the Nancy Grace Roman space telescoe lifts off from Launch Complex 39A at the Kennedy Space Center in Florida on Augst 30, 2026. NASA launched its new flagship space telescope on Sunday, embarking on a multi-year mission to create an unprecedented map of the cosmos and shed light on some of the biggest mysteries in physics.

Overview

  • The Roman telescope, which launched on Aug. 30, separated cleanly from its Falcon Heavy rocket and is on a roughly three-month coast to the Sun–Earth L2 point where it will enter a commissioning phase.
  • Early post‑launch steps have gone as planned: communications handover to NASA’s Deep Space Network, solar arrays and a lower sunshade deployed, and an initial mid‑course correction burn completed.
  • NASA has powered on the Coronagraph Instrument and begun its multi‑month calibration program to test starlight suppression techniques for direct imaging of nearby planets.
  • The Wide Field Instrument, a 300‑megapixel infrared camera made from 18 detectors, will be activated in the coming weeks before about 100 days of commissioning and first public images expected in early 2027.
  • Once operational, Roman will survey the sky far faster than Hubble, return roughly 1–1.4 terabytes of data per day with immediate public release, and use AI, machine learning and citizen science to enable wide community research and unexpected discoveries.
