NASA says the James Webb Space Telescope will be hit by meteorites

The James Webb Space Telescope is slated to unlock the universe to researchers with powerful instruments capable of looking further back in time than ever before.

A new report published in Nature last Friday estimates that the James Webb Space Telescope (JWST) will be slapped by at least one meteorite per month for the rest of its life. Notably, NASA stated in early June that its next-generation space telescope was struck by a micrometeorite in May, and that the impact didn't cause any significant damage. However, over time NASA estimates that micrometeorite impacts will reduce the total lifespan on if the observatory.

So far, Webb has been smacked by five micrometeorites, with the fifth being the most recent and the largest. When Webb was being designed, engineers knew the large observatory would be prone to fast-moving dust particles impacting the mirrors, which is why they took a large amount of time testing how much Webb's mirrors could endure micrometeorite impacts.

According to estimations, on average, Webb will be hit with one micrometeorite per month, and after 10 years, only 0.1% of the primary mirror would be damaged. Webb has an anticipated lifespan of 20 years.
