JWST mirror hit by micrometeoroid, but NASA says damage is minimal

Don’t panic! But sometime between May 23 and 25, 2022, the James Webb Space Telescope was hit by a micrometeoroid, a tiny piece of rock that came off a comet or asteroid. The telescope sustained a small bit of damage to one mirror segment, but engineers say it’s fine and the observatory is still well above its mission performance requirements.

OK, phew.
