Green donuts debut as Roman Space Telescope runs first test images
TL;DR
NASA activated the Nancy Grace Roman Space Telescope’s 300-megapixel camera for initial test images, which are currently out of focus as calibration work continues for months. The tests covered data flow, the element wheel filters, and the focus mechanism while detectors cooled to about −183°C. The Wide Field Instrument will image a field the size of the full Moon with Hubble-like sharpness, enabling the mission’s planned surveys of exoplanets, dark energy, and cosmic structure during a 5-year primary mission at L2, with potential extensions based on fuel.
