NASA’s Nancy Grace Roman Space Telescope will take sharper images and work longer than engineers first expected, early results from its commissioning show.
The telescope’s main camera is performing nearly 30 percent better than predicted, NASA said. Engineers measured its optical error at about 63 nanometers after aligning the optics, against a requirement of about 90 nanometers. Precise launch maneuvers also saved so much propellant that the mission could run for twice as long as first planned.
Roman launched on August 30, 2026, aboard a SpaceX Falcon Heavy rocket from NASA’s Kennedy Space Center in Florida. It is now travelling to a point about 1 million miles from Earth known as the second Sun-Earth Lagrange point, where it will settle into position to survey the sky.
The observatory carries a 300-megapixel infrared camera with a field of view at least 100 times wider than Hubble’s. NASA expects it to measure light from as many as a billion galaxies over its lifetime and to hunt for new exoplanets while probing dark energy.
Roman is still in its commissioning phase, and NASA expects to release its first science images in early 2027. The telescope is named after astronomer Nancy Grace Roman.
