Briefing

What Hype is tracking

The launch advances NASA’s next major space-based astronomy mission, following the observatory’s final integration and launch rehearsals at Kennedy Space Center.
Roman’s planned operating location at L2—about one million miles from Earth—requires a roughly three-month transit before science operations can begin.
Its 300-megapixel telescope is designed to investigate dark energy, creating a major new data set for cosmology and space-science research.
