| Summary | NASA's next flagship astronomy mission. Roman's 300-megapixel Wide Field Instrument (WFI) has Hubble-equivalent resolution but covers 0.28 square degrees per pointing — 100× wider than Hubble. Its 5-year primary mission will census dark matter, dark energy, and exoplanet populations across the Milky Way. |
