NASA's Nancy Grace Roman Space Telescope team recently flight-certified all 24 of the detectors the mission needs. When Roman launches in the mid-2020s, these devices will convert starlight into electrical signals, which will then be decoded into 300-megapixel images of large patches of the sky. These images will allow astronomers to explore a vast array of celestial objects and phenomena, bringing us closer to solving many pressing cosmic mysteries.
"As the telescope's eyes, Roman's detectors will enable all of the mission's science," said John Gygax, the focal plane system manager for the Roman Space Telescope at NASA's Goddard Space Flight Center in Greenbelt, Maryland. "Now, based on our testing results, our team can confirm these infrared detectors meet all the requirements for Roman's purposes."
