James Webb Space Telescope tweaks observing plans to avoid micrometeoroids

After taking a few hits, NASA’s newest space telescope will adjust its observation strategy to avoid its mirror being struck by tiny space rocks.

The James Webb Space Telescope (Webb or JWST) has yet to mark its launch anniversary, but over the past months 14 dust-size micrometeoroids have hit its golden mirror, which stretches 21 feet (6.5 meters) across. The observatory’s view remains stunning, but mission personnel have decided to adjust the telescope’s operations to avoid directly facing what experts have identified as “micrometeoroid avoidance zones.”
