James Webb telescope hit by micrometeoroid, sustains no major damage

Between May 23 and 25, 2022, NASA’s James Webb Space Telescope sustained a micrometeoroid impact to one of its primary mirror segments. While such strikes are an unavoidable aspect of operating any spacecraft, this most recent impact was larger than was modeled, and beyond what could have been tested on the ground.
