James Webb UPDATE : There’s A PROBLEM with the Telescope!

The James Webb Space Telescope has been designed to answer many of the core questions that have animated astronomers over the past half-century. With a $10 billion price tag, it is one of the most ambitious engineering initiatives ever attempted. But for it to achieve its potential — nothing less than to rewrite the history of the cosmos and reshape humanity’s position within it — a lot of things have to work just right.
So, is James webb actually working perfectly? Or are the rumored problems actually true? Let’s find out!
Welcome to Space World. In today’s video we are going to talk about an update on James webb telescope according to which there’s a problem with it. So, if you want to know more about it then stay with us until the end of the video.
Exploring strange new worlds. Understanding the origins of the universe. Searching for life in the galaxy. These are not the plot of a new science fiction movie, but the mission objectives of the James Webb Space Telescope, the long-awaited successor to the Hubble Space Telescope.
However, there have been news about the space observatory suffering from minor problems. According to sources, the James Webb is currently experiencing problems with its MIRI instrument. The problem is due to increased friction in one of MIRI’s mechanisms in the Medium-Resolution Spectroscopy (MRS) mode. The observatory is otherwise healthy, but the team decided to stop observations using MRS mode until they find a solution.
JWST’s Mid-Infrared Instrument (MIRI) is one of the most important instruments onboard. It allows the telescope to see in the wavelength range from 5 to 27 micrometers. The instrument has 4 modes: imaging, medium-resolution spectroscopy, low-resolution spectroscopy, and corona-graphy.
On August 24 during preparation for observations using MIRI’s medium-resolution spectroscopy mode (MRS) the team detected a problem with a grating wheel. Its function is to select between short, medium and longer wavelengths. During the setup process leading to scientific observation, the telescope detected increased friction in the mechanism, which caused the issue.
Following preliminary health checks, an anomaly review board was convened on September 6 to assess the best path forward. As a result, JWST paused observations in the MRS mode using MIRI until an adequate solution is found. Three remaining modes of MIRI are still working properly. Other instruments aren’t affected either.
So, now that we know the problem is not a serious one, let’s take a look at some of the Previous Problems with James Webb.
It’s not the first time that James Webb experiences issues since its launch in December 2021. Previously a larger-than-expected micrometeoroid hit one of JWST’s mirror segments. There was enough damage to be detected by the team, but the quality of observations is still exceeding original expectations.
Despite the current issues, we should still expect new images to come. So, recent releases of the Tarantula Nebula and the Orion Nebula definitely won’t be last. There are many other modes the observatory can use for now. Besides, there are a lot of things that James Webb already observed but did not release to the public yet. Like the images of the TRAPPIST-1 system, which it took during the first month of scientific operation.
