The James Webb Infrared Space Observatory has resumed full-fledged operation of the MIRI spectrometer, which was disrupted two months ago due to an instrumental anomaly. Its cause was the increased friction between the elements of the wheel with diffraction gratings.

MIRI consists of a camera and a four-channel spectrograph and allows “James Webb” to make observations in the middle and long infrared wavelengths. The instrument, unlike other instruments, has an additional cooling system that allows it to reach a temperature of seven Kelvin, minimizing thermal interference during observations. MIRI observes a wide variety of objects such as protostars, very distant galaxies, comets and Kuiper Belt objects, as well as exoplanets.

In mid-August 2022, the observatory team discovered an anomaly in the operation of the instrument associated with a wheel with diffraction gratings, which led to the termination of observations in the medium resolution spectroscopy (MRS) mode.

As a result, the engineers came to the conclusion that the most likely cause of the anomaly is increased friction between the elements of the wheel center bearing assembly under certain conditions. After that, instructions were developed for the further operation of the device, taking into account the presence of a problematic bearing. On November 2, 2022, a trial session with MIRI took place, after which scientific observations in the MRS mode were resumed on November 7. They will be carried out in full after additional checks of the new mode of operation of MIRI.

Perfect car for travel Toyota showed a three row hybrid

Toyota has announced the release of a new SUV Grand Highlander, which will compete with large cars of the same class.

While the current Highlander boasts impressive hybrid fuel economy, it can’t compete in third-row space with the Kia Telluride, Volkswagen Atlas and Chevy Traverse.

Toyota describes the Grand Highlander as “the ultimate travel car”, citing increased legroom and luggage space. The first teaser of the new three-row SUV gives us an idea of ​​what the rear will look like.

The Hybrid Max badge indicates that the Grand Highlander Platinum will get the same powerful powertrain as the Crown’s top-of-the-line sedan. and 542 Nm of torque. Toyota hasn’t provided any information about the Grand Highlander’s available powertrains, but it’s likely that the standard 265bhp turbo-four from the base Highlander will be carried over to the new model.

It is not known when the new Grand Highlander will hit the roads, but it is known that Toyota plans to fully introduce the SUV at the Chicago Auto Show on February 8th.

Such behavior is tantamount to suicide the insider believes that

Well-known insider Ice Universe, who regularly shares exclusive information about the latest in the mobile industry, made a prediction about the upcoming policy of Samsung.

He said that against the background of competition with Chinese manufacturers, Samsung, led by the current head of the mobile division, will remain “lazy.”

Chinese brands and Apple will take practical action to convince Samsung and Tae Moon Ro (T.M. Roh) stagnate, blindly cut costs, strive for high profits and be lazy. This behavior is tantamount to suicide.

“Such behavior is tantamount to suicide,” the insider believes that Samsung will “mark time” and S23 sales will be low

In addition, the insider made a forecast about sales of the flagship smartphone Samsung Galaxy S23 Ultra, as well as other upcoming models of the manufacturer.

It can be foreseen that sales of the Galaxy S23 and S23+ will become increasingly insignificant. Samsung will only be able to maintain a high level of sales of the flagship model Galaxy S23 Ultra. Until the release of the Fold5 and Flip5, sales of the Fold4 and Flip4 will drop significantly.

Ice Universe was the first to accurately talk about the new trend of smartphones with waterfall screens, the notch in the iPhone X, the new design of the iPhone 14 and Samsung’s 200-megapixel image sensor. Recently, he was the first to accurately report that Redmi Note 12 Pro + will receive a 200-megapixel main camera. Exclusive information about new products is leaked to him by sources in the research and development department of the South Korean giant.
