The telescope’s space pocket is not an absolute void – and now the inevitable has happened, with a tiny piece of rock, a micrometeorite, colliding with one of Webb’s mirror sections. But there is no need to panic. The engineers who built the telescope are extremely aware of the rigidity of space, and Webb has been carefully designed to withstand them. “We always knew that Webb would have to overcome the space environment, which includes hard ultraviolet light and charged particles from the Sun, cosmic rays from exotic sources in the galaxy and occasional micrometeorite impacts into our solar system,” says the engineer and technical....
