NASA Roman Space Telescope activates 300-megapixel camera

NASA’s Nancy Grace Roman Space Telescope has successfully activated its 300-megapixel Wide Field Instrument (WFI), a major milestone in its mission to survey large areas of the universe with high detail. The infrared camera is designed to provide views comparable to the Hubble Space Telescope but across much broader fields of view. Additionally, the telescope’s Coronagraph Instrument has completed initial digital, electronic, and mechanical checks.

The observatory is currently traveling toward the second Lagrange point (L2), approximately 1.6 million kilometers from Earth. During the commissioning process, engineers cooled the detectors to operating temperatures as low as minus 183 degrees Celsius. The mission aims to investigate dark energy, map the distribution of matter, and search for exoplanets.

To support the expected daily data flow of approximately 1.4 terabytes, NASA has successfully tested ground station infrastructure in Japan, the United States, and Australia. These stations achieved data transfer speeds of up to 500 megabits per second. Regular scientific operations are anticipated to begin by early 2027.
