The telescope was presented at the Goddard Space Flight Center in Maryland and is expected to launch as early as September aboard a SpaceX rocket. The mission, which cost more than $4 billion and took over a decade to develop, is named after pioneering astronomer Nancy Grace Roman.
The Nancy Grace Roman Space Telescope is in final preparations for an early September launch, eight months AHEAD of schedule and UNDER budget.

Scientists say the telescope will significantly expand humanity’s understanding of the cosmos. With a field of view about 100 times larger than that of the Hubble Space Telescope, Roman will be able to scan vast regions of space more efficiently than its predecessors.
Researchers expect the telescope to discover tens of thousands of planets beyond our solar system, as well as billions of galaxies and stars. Its advanced instruments will also allow scientists to observe distant cosmic events, including supernovae, and gather unprecedented amounts of data.
One of the mission’s key goals is to study elusive phenomena such as Dark matter and Dark energy, which together are believed to make up most of the universe. Using infrared technology, the telescope will look billions of years into the past, helping scientists understand how the universe has evolved over time.
The Roman telescope will work alongside other major observatories, including the James Webb Space Telescope, to provide complementary insights into cosmic structures and processes.
