NASA says that the telescope is fine.
New telescope James Webb survived a “space accident”. A micrometeorite crashed into a segment of its main mirror between May 23 and 25, according to NASA. However, the collision had some effect on the data obtained. More thorough analysis and measurement of the efficiency of the device continues.

The agency notes that such collisions will continue throughout the telescope's mission in space. Scientists have been ready to test the spacecraft's mirrors on Earth.

The James Webb Mirror was designed to withstand the bombardment of micrometeorites – particles the size of dust flying at extreme speeds. During the construction of the observatory, experts conducted simulations, as well as real tests on mirror samples to find out how to strengthen them. However, the collision that actually took place was stronger than the simulations on Earth.
“James Webb” is also able to determine and adjust the position of the mirrors, which allows you to adjust the result of collisions. By adjusting the position of the damaged segment, engineers can compensate for some of the distortion. This minimizes the effect of any impact, although not all changes can be compensated in this way. Engineers have already made the first such adjustment for the recently damaged C3 segment, and additional planned adjustments to the mirrors will continue to be finalized.
It will be recalled that the development of the telescope began in 1996. It was originally planned to be launched in 2007, but the mission has faced a number of delays and delays. As a result, the project's budget has increased to $ 9.7 billion, of which $ 861 million will be spent in the first five years after launch. James Webb will study galaxies. of the early universe, the study of the formation of new stars and the observation of the planets of the solar system.
The launch of the telescope was postponed several times last year. Yes, it was planned that it would be launched on December 18, then the start was postponed to December 22, and later – to December 24. The launch took place on December 25.
