NASA engineers at Kennedy Space Center in Florida are preparing the Nancy Grace Roman Space Telescope for launch no earlier than August 30. The current target is roughly nine months ahead of the agency's earlier commitment date.

Technicians have lifted the observatory onto a specialized work stand and powered it on for post-shipping checks. Upcoming work includes testing six solar-array panels, examining insulation and thermal blankets, checking propellant tanks, and loading about 290 gallons of hydrazine before the telescope is enclosed in its launch fairing.

Roman is designed to travel to the Sun-Earth Lagrange point 2, about one million miles from Earth. From that stable location, its wide field of view will survey large portions of the sky to study dark matter, dark energy, black holes, galaxies, and planets beyond our solar system. NASA plans to launch the observatory on a SpaceX Falcon Heavy from Launch Complex 39A.
