Nasa sets late-August launch date for Nancy Grace Roman Space Telescope

Nasa has officially set Sunday, August 30, 2026, as the launch date for its highly anticipated Nancy Grace Roman Space Telescope, the space agency's next major space observatory after the James Webb Space Telescope.The spacecraft is scheduled to lift off aboard a SpaceX Falcon Heavy rocket from Launch Complex 39A at Nasa's Kennedy Space Center in Florida at around 4:56 pm IST.

After launch, Roman will travel to the Sun-Earth Lagrange Point 2 (L2), around 1.5 million kilometres from Earth, where it will operate alongside Webb.From this stable location, the telescope will have an uninterrupted view of deep space while remaining shielded from much of the Sun's and Earth's heat. Technicians and engineers at Nasa’s Kennedy Space Center prepare the telescope.
