Roman’s Wide Field Instrument powers on for the first time

NASA shared the instrument’s first test image on September 15, 2026, saying scientists had begun adjusting its focus.

This test image captures the very first photons of starlight to reach the Wide Field Instrument on NASA’s Nancy Grace Roman Space Telescope. It was taken as an initial performance assessment with the detector array still stowed as it was for launch, far from best focus. Roman’s primary science instrument has opened its eyes to the universe for the first time, revealing a sea of out-of-focus stars, each spread out over many thousands of pixels. The image, which zooms into one detector and zooms again to a single star in the insets, offers a baseline the Roman team will work from to align the telescope’s optics and tune the focus. The team will soon activate the instrument’s fine-guidance system, which will mean Roman can lock onto targets. They’ll also focus the observatory, which will shrink each star’s light to appear as a crisp point, rather than the broad, donut-like features seen here (which appear as expected given the instrument’s present configuration).

TLDR

NASA announced that Roman’s Wide Field Instrument had powered on for the first time, with scientists beginning focus adjustments. It shared the first test image on September 15, 2026. A user sharing the announcement described the blurry, ring-shaped stars as expected before focus is set—not a sign of failure.
