Nancy Grace Roman Space Telescope test images
Nancy Grace Roman Space Telescope test images Rob Beschizza 11:08 am Tue Sep 22, 2026 Nasa activated the 300-megapixel camera on the Nancy Grace Roman Space Telescope this weekend and the first test images are in. The results are out of focus—testing and calibration will take months—but delightful all the same, hailed as "green donuts." From NASA's press release: the team activated the calibration system, which they used the next morning to start sending test data through the instrument and down to engineers on the ground. On Saturday evening, the focus shifted to the element wheel — a system of filters, prisms, and other optics used to tune the wavelengths of light that reach the detectors and spread light from cosmic objects into individual colors — as engineers tested it in the absence of gravity for the very first time.
