A Monumental Milestone: WFI Activation in Orbit

On September 28, 2026, NASA confirmed that the Roman Space Telescope’s Wide Field Instrument (WFI)—a 300‑megapixel infrared camera—has been powered on and passed its initial in‑space tests . The activation marks a critical milestone in the mission’s commissioning phase, bringing the telescope one step closer to full scientific operations.

Unprecedented Field of View Meets Hubble‑Level Clarity

The WFI comprises 18 infrared detectors, each roughly the size of a saltine cracker, combining for a sensing area akin to a laptop screen . It delivers the same angular resolution as Hubble but captures sky patches more than 100 times larger per image . This means Roman can survey the sky up to 1,000 times faster than Hubble while maintaining comparable infrared sensitivity and detail .
