NASA's Roman Space Telescope launches aboard Falcon Heavy

The Nancy Grace Roman Space Telescope has launched aboard SpaceX’s Falcon Heavy, progressing through key milestones such as stage separation, a second-stage burn, and approaching orbit, while SpaceX’s boosters execute controlled returns as part of the mission’s reusable-launch strategy. The mission aims to answer major questions in cosmology, including dark energy, dark matter, and exoplanets, with science observations expected to begin in the coming years, complemented by market and tech context around SpaceX and the telescope’s $4.3 billion price tag and hardware capabilities.
