According to the information given in a paper published on arxiv.org, the large mirror of the telescope was not damaged by the strike of the small meteoroid, but in mid-May the meteorite hit the left side of the telescope there. Damage has happened. NASA’s report says that between January and June, 6 attacks of micro meteorites on this telescope caused little damage 5 times. But a meteorite has damaged the telescope. The incident took place between 22 and 24 May.
Damage assessment revealed that the collision caused damage to a mirror segment labeled C3, which left a permanent damage to the telescope. This incident happened with the James Webb Telescope in its commissioning phase. It is said to be the phase when the telescope was setting its instruments in space and testing them.
Due to the sixth collision, the wavefront error of the segment has increased from 56 nanometers to 178 nanometers. Experts have told that the mirrors of this telescope are in contact with space, so it is difficult to avoid the attack of micro meteorites. The good thing is that due to the collisions so far, the telescope has suffered negligible damage. These attacks did not affect the infrared image capability of the telescope. Images captured by Telescope and released last week attest to this.
According to the report, there was a change in the data of that segment due to a small meteorite hitting the C3 segment on 22-24 May, but the effect was too small for the whole telescope, as only a small part of the telescope was affected. . Collisions from smaller meteorites are said to be a major problem for the 21-foot diameter mirror of the James Webb Space Telescope, as the mirror is directly exposed to space, whereas this is not the case with the Hubble Telescope.
Although it is far from Earth, there scientists had predicted such attacks only once a month. This telescope was launched last year. It is believed that it will replace the Hubble Telescope, which has been serving in space for the last 30 years.
