IT's home, June 9, the James webb space telescope (JWST) was struck by a piece of small space rocks, during the period of May 23 to 25, a micrometeoroid hit one of the telescope primary mirror, but the NASA team is in charge of the operation of the telescope does not expect the impact to the observatory data have a significant impact.

IT Home understands that JWST launched in late 2021 and reached fixed orbit in January. Since then, the engineering team has been preparing for scientific observations, and the most delicate and tricky part of the observatory is its primary mirror, which is made up of 18 smaller hexagonal mirrors coated with gold.

The solar system is full of micrometeoroids, so it's not surprising that one of them hit the JWST. The mirrors were designed to withstand small impacts and were tested before the spacecraft launched.

However, the meteor that hit the telescope in May was larger than anything the NASA team tested or simulated on the ground, and because it was not part of a meteor shower, it was not predicted. If predicted in advance, telescope operators will be able to turn it to avoid a direct impact.

While the impact's impact on the data was large enough to be detected, the team found that future images from the telescope would not degrade too much. Currently, the JWST's performance is still well above what is needed for its planned scientific observations, including those of the early universe and the earliest galaxies.
