Roman's Wide Field Instrument added to the Mirror Assembly

  • Released Tuesday, January 21, 2025

Here technicians install the Wide Field Instrument into the Nancy Grace Roman Space Telescope Instrument Carrier.

Using this instrument, each Roman image will capture a patch of the sky bigger than the apparent size of a full Moon. Hubble’s infrared images, taken with its Wide Field Camera 3, are about 200 times smaller. Even Hubble’s widest exposures, taken with the Advanced Camera for Surveys, are nearly 100 times smaller. Over the first five years of observations, Roman will image over 50 times as much sky as Hubble covered in its first 30 years, surveying the sky up to 1,000 times faster than Hubble can while maintaining similar sensitivity and infrared resolution.
