One mirror’s segment of Webb Space Telescope was hit by a micrometeoroid


The space telescope’s mirror was hit by a micrometeoroid before beginning the mission projected for many years. The incident detected now occurred between May 23 and May 25. A micrometeoroid is a particle in space that is smaller than a grain of sand. dust particles are accelerated to extreme velocities. It’s almost impossible to avoid these impacts.The effects of the impact were noticeable in recent data readouts but fortunatelly it can however work well. “With Webb’s mirrors exposed to space, we expected that occasional micrometeoroid impacts would gracefully degrade telescope performance over time,” said Lee Feinberg, Webb optical telescope element manager at NASA.


The telescope sits in a dynamic part of the solar system that comes with a bounty of hostile space weather phenomena. Webb’s mirrors are perhaps the most essential component of the $10 billion spacecraft. Each hexagonal mirror segment is fully adjustable. The telescope can adjust its mirror positions to correct for impacts from micrometeoroids, minimizing the effects such collisions can have. The telescope’s first full-color images are expected on July 12. In the future, the Webb team will work closely with micrometeoroid prediction experts at NASA’s Marshall Space Flight Center in Huntsville, Alabama. The Webb Space Telescope will be able to peer inside the atmospheres of exoplanets and observe some of the first galaxies created after the universe began.
