The telescope's Wide Field Instrument was expected to perform at a certain level, and it now beats that prediction by nearly 30%. Sharper views should make its planned cosmic surveys more precise. The fix came from very small mechanical adjustments rather than new hardware.
From ScienceDaily
NASA’s Nancy Grace Roman Space Telescope has exceeded expectations after engineers made incredibly tiny adjustments to sharpen its view of the universe. By moving a mirror just one-sixteenth the width of a human hair, the team helped bring its powerful instruments into near-perfect alignment. Roman’s Wide Field Instrument now produces image quality nearly 30% better than predicted, promising exceptionally sharp cosmic surveys.

NASA has a special space telescope called Roman. Engineers moved one of its mirrors by a tiny amount. Now the telescope takes much sharper pictures of space. What do you think you would look for first with a sharp space camera?
