James Webb Telescope's technical fault: Problem with the instrument taking pictures of space, NASA sets up review board

 A technical fault has occurred in a part of the world's most powerful James Webb Space Telescope. The name of this device is Mid-Infrared Instrument (MIRI). The telescope, located 1.5 million kilometers from Earth, was launched on December 25 last year, since then it has been helping scientists to unravel the mysteries of space. Now to improve its technical problem, the US space agency NASA has formed a review board.

First know, what is MIRI instrument?
The MIRI instrument is actually a camera and spectrograph. With its help, the James Webb Telescope is able to see the wavelength range of 5 to 27 micrometers. MIRI has four observing modes. These include imaging, low resolution spectroscopy, medium resolution spectroscopy and coronagraphic imaging.

What went wrong with the instrument?
According to NASA, there has been a technical glitch in MIRI's medium resolution spectroscopy. During a science observation on 24 August, a mechanism supporting it was found to have excessive friction. This mechanism is a kind of wheel, through which scientists are able to choose short, middle and long wavelengths during their observations.

After recognizing this problem, the scientists formed a review board on 6 September to solve the problem. Until the problem is fixed, researchers will not be able to use the medium resolution spectroscopy mode in the telescope. However, all other observing modes are working as before.

This
is not the first time that a technical fault has occurred in any part of the 1,000 crore rupees (10 billion dollars) James Webb Telescope. In May this year, 19 small stones in space damaged one of the telescope's 18 mirrors. However, even after that, the quality of amazing pictures of space taken through the telescope is better than expected.
