Roman Space Telescope Cleared for Launch to L2 on Aug. 30

The telescope was certified for final launch work and will use wide-field infrared surveys to map billions of galaxies, measure dark matter and probe dark energy, conduct an exoplanet census, and return massive daily data volumes.

Overview

  • Mission managers completed a Flight Readiness Review that certified the observatory to proceed with final launch integration after a full launch‑day dress rehearsal.
  • Technicians fueled Roman with 290 gallons of hydrazine on July 25 and encapsulated the observatory inside Falcon Heavy’s payload fairing ahead of mating to the rocket at KSC.
  • NASA and SpaceX are targeting liftoff at 7:26 a.m. EDT on Sunday, Aug. 30, with Falcon Heavy side boosters planned to land back at the Cape and the expendable center core discarded.
  • After separation, Roman will travel to the Sun–Earth Lagrange point 2 and undergo roughly 100 days of commissioning before routine science operations begin during a five‑year primary mission.
  • Roman pairs a 2.4‑meter mirror with a Wide Field Instrument and a coronagraph demonstrator to survey more than two billion galaxies, search for thousands of exoplanets, produce about a terabyte of data per day, and rely on a NASA‑led international partnership for operations and data analysis.
