NASA's Roman Space Telescope activates primary instruments

NASA has successfully begun the activation of the Nancy Grace Roman Space Telescope's primary instruments. The Wide Field Instrument (WFI), a 300-megapixel infrared camera, has been powered on following a decontamination and cooling process. Initial test images show blurred stars, which is expected as engineers continue to calibrate the optics and focus systems. The telescope is currently traveling toward the Sun-Earth Lagrange point L2, approximately 1.5 million kilometers from Earth.

Due to an exceptionally precise launch by SpaceX's Falcon Heavy and a lighter-than-expected spacecraft mass, the mission's operational lifespan has been significantly extended. While originally designed for a 5-to-10-year mission, current fuel reserves and orbital dynamics suggest the telescope could operate for at least 22 years.

The Roman telescope will focus on studying dark energy, mapping the distribution of matter in the universe, and searching for exoplanets using techniques such as gravitational microlensing. Scientific imaging is expected to begin in early 2027.
