President Donald Trump called into a NASA press conference to celebrate the launch of the Nancy Grace Roman Space Telescope, despite his administration previously proposing to cancel the mission.

The telescope launched aboard a SpaceX Falcon Heavy rocket from Florida and is designed to study dark energy, dark matter and the evolution of the universe.

Trump praised NASA and the mission during the event, highlighting the importance of American leadership in space exploration.

The Roman telescope is expected to provide scientists with a wide field of view that could help answer major questions about the universe and discover large numbers of distant objects, Space.com has reported.

The mission’s launch represents a significant achievement for NASA after years of development and uncertainty over its future funding.
