Summary
Sept. 15 brought Roman’s first test image: hundreds of stars appearing as green rings after NASA switched on the telescope’s 300-megapixel infrared camera for the first time.
The distorted view reflects an instrument still being tuned, but NASA said the Wide Field Instrument is operating as expected during Roman’s commissioning on its 1.6 million-kilometer trip to L2.
Early 2027 is the target for first full science images, with Roman expected to match Hubble’s sharpness while covering 100 times more sky in each shot.
18 detectors in the camera will send about 1.4 terabytes of data to Earth each day, supporting surveys of dark energy, galaxies and exoplanets; NASA also said a successful burn could extend the mission to 22 years from 10.
Why did NASA's newest space telescope send back bizarre green rings, and what does this mean for its upcoming mission?
With fuel for 22 years, how will scientists handle the massive daily data deluge from this cosmic observatory?
How will a camera the size of a laptop screen hunt down thousands of invisible rogue planets wandering deep space?
NASA’s Roman Space Telescope: Inside the 2026 First Light, 300-Megapixel Imaging, and the Next Era of Cosmic Surveys
Overview
After launching aboard a SpaceX Falcon Heavy in August 2026, NASA’s Nancy Grace Roman Space Telescope traveled to its orbit at L2 and quickly began its commissioning. By mid-September, engineers activated the Wide Field Instrument and captured the first test image, which showed broad green rings due to unaligned optics. This out-of-focus image was expected and allowed the team to calculate precise mirror adjustments. Roman’s advanced design ensures high stability and rapid sky surveys, capturing huge areas much faster than Hubble. Its wide-field images and massive daily data return will help map dark matter, study cosmic expansion, and discover new exoplanets, marking a major leap in space science.
