Roman Space Telescope Records First Light During Transit to L2

Initial instrument activations let engineers begin alignment and commissioning while NASA reports a fuel-based projection that could extend operations for decades.

Overview

  • The telescope’s Wide Field Instrument was dried, cooled, and its 18 infrared detectors activated in mid-September, producing the first test image that captured the initial photons of starlight.
  • Engineers took the out-of-focus test image as a functional check to start optical alignment and focus work that will continue during a roughly 100-day commissioning period after Roman reaches Sun–Earth L2.
  • Teams have confirmed Earth-to-space communications with the Coronagraph Instrument and begun its preliminary tests, a key step for demonstrating techniques to block starlight and image exoplanets directly.
  • A precise early midcourse correction used far less propellant than expected, and NASA now estimates a fuel-based operational horizon of about 22 years though the actual mission lifetime will depend on hardware and other consumables.
  • Once fully commissioned, Roman’s 300-megapixel wide-field camera will deliver very large public data streams to map billions of galaxies and stars, probe dark matter and dark energy, and broaden the census of exoplanets.
