Roman Commissioning

Where is Roman? Roman is making its three-month journey from Earth to Sun-Earth Lagrange Point 2, or L2. Along the way, Roman is undergoing a process called commissioning, where systems are turned on, adjusted, calibrated, and prepared for science operations. Commissioning is the time for scientists and engineers to make sure that Roman is performing […]

The top 3

  1. Unprecedented Wide Field of View: Roman's Wide Field Instrument (WFI) boasts a field of view 100 times larger than Hubble's infrared instrument, enabling it to survey vast cosmic regions with comparable image quality in significantly less time.
  2. Hubble-Class Resolution with Panoramic Scope: Roman's 2.4-meter (7.9-foot) primary mirror, identical in size to Hubble's, delivers comparable sensitivity and resolution but across a much wider field, allowing it to image billions of galaxies and cover 50 times more sky than Hubble in its prime mission.
  3. Advanced Coronagraph for Exoplanet Imaging: Roman's Coronagraph Instrument is a technology demonstration designed to suppress starlight by a factor of a billion, enabling direct imaging and spectroscopy of faint exoplanets and paving the way for future missions to characterize potentially habitable worlds.
