James Webb Space Telescope adjusts observing plans to avoid micrometeoroids

After a few hits, NASA’s newest space telescope will adjust its observing strategy to avoid hitting its mirror with small space rocks.

The James Webb Space Telescope (Webb or JWST) has yet to celebrate its launch anniversary, but in recent months 14 dust-sized micrometeoroids have hit its gold mirror, which is 6.5 meters wide. The view from the observatory remains stunning, but mission personnel have decided to modify the telescope’s operation to avoid directly confronting what experts have identified as “micrometeoroid avoidance zones.”
