NASA's Roman Space Telescope Powers Up 300-Megapixel Imaging System

The Nancy Grace Roman Space Telescope has successfully energized its 300-megapixel Wide Field Instrument, representing a significant achievement in its commissioning phase. This infrared imaging system is engineered to capture large areas of the sky while delivering detail comparable to that of the Hubble Space Telescope. Following the cooling process to approximately minus 225 degrees Fahrenheit, the telescope's 18 infrared detectors were activated, ultimately reaching temperatures near minus 300 degrees Fahrenheit. Currently, the telescope is en route to its designated location at L2, situated around one million miles from Earth. NASA anticipates that Roman will produce its initial scientific images by early 2027 as it undergoes further testing and calibration.
