NASA has reported that a micrometeoroid strike has caused some damage to the James Webb Space Telescope (JWST). The largest of five meteoroid strikes since its December 2021 launch occurred between 23 and 25 May, causing damage to one segment (segment C3) of its 6 m main mirror.
The distortion can be minimised by altering the position of the segment, but it cannot be eliminated. The performance of the telescope, reportedly valued at more than US$11 billion, remains within its specification.
