NASA’s Nancy Grace Roman Space Telescope has arrived at Kennedy Space Center in Florida, marking a major milestone. The observatory will now undergo roughly 70 days of prelaunch processing before its scheduled liftoff.
The spacecraft is expected to launch on a SpaceX Falcon Heavy rocket no earlier than August 30. Once deployed, it will study dark energy, exoplanets, and infrared astrophysics from a Sun-Earth L2 orbit.
Processing includes final testing, fueling, and integration with the payload fairing. The telescope's wide-field instrument gives it a field of view 100 times larger than Hubble's, enabling rapid sky surveys.
The Roman mission, formerly known as WFIRST, is designed to last at least five years. It will build on discoveries from Hubble and Webb, probing cosmic expansion and planetary formation.
Some experts question whether the mission's $4.3 billion cost will deliver proportionally greater scientific returns than smaller, more focused telescopes. However, its survey capability is expected to produce unprecedented datasets for decades.
