Fully used James-Webb space telescope

The James-Webb Space Telescope, with its main mirror, successfully completed the last phase of its deployment on Saturday, January 8th. It is now in its final stages, and in more than five months, it will be able to begin its study of the universe.

The iconic main glass of the telescope was 6.5 meters in diameter, so it was too large to fit on a rocket. On departure, Two weeks ago. So both its sides should be folded backwards.

NASA broadcast live images of the control room on Saturday morning, January 8, 2022, where dozens of engineers applauded the announcement of the complete deployment of the pilot telescope off the east coast of the United States.

The first of those two wings was used on Friday and the second was opened as scheduled on Saturday morning, NASA said. Space agency teams continued to lock it up to protect it permanently. “I was flexibleThomas Surbuchen, head of NASA’s scientific missions, said in a video. What an extraordinary step. ” NASA aired live footage from the control room Saturday morning, where dozens of engineers praised the news of the telescope’s full deployment as it flies from Baltimore on the U.S. East Coast.

Scientific tools still need to be cooled

Placing such a telescope in space, not only its mirrors but also its thermal shield earlier this week, is a very dangerous process that has not been carried out in the past. The task now seems to be on the right track to success.

However, before operation, the telescope must still reach its final orbit of 1.5 million kilometers from Earth, and must be continuously cooled before scientific instruments can be measured very accurately.

James-Web, the most powerful space laboratory ever designed, should make it possible for the Big Bang to observe the first galaxies that formed about 200 million years later.
