The Webb space telescope also got the mirrors open


All devices in the space telescope James Webb have been opened. The last side of the main mirror was opened and put in place on Saturday evening Finnish time.

The mirror is 6.5 meters in diameter. It consists of 18 smaller mirrors, six of which were attached to the sides of the main mirror at the end of last week.

Webb soared into space on December 25 from French Guiana. Thousands of people who built and designed the web feared the weeks following the pre-departure. They were nicknamed “Two Weeks of Horrors”.

A total of 344 different operations had to be targeted remotely. This is how it got out of its wrappers, all the way from the heat shield to the mirrors.

The telescope had 178 different mechanisms for opening the parts. Every operation had to be a success, though not a one-off.

It was also possible to open and restart the various hinges, motors and belts.

But no new companies were needed once.

“Unbelievable,” he said Bill Ochs. He is the program manager for Nasa and Webb.

“We are now at a stage where Webb is already over a million miles from Earth and we have a telescope operating there. Congratulations to everyone. ”

Webb’s air traffic control in Baltimore, Maryland, rejoiced as it completed the final stages over the weekend. Air Traffic Control is located at the Space Telescope Science Institute (STScI) at Johns Hopkins University.

On Thursday, January 6, radiation protection was also quickly tuned into place. It is a 1.2 x 2.4 meter aluminum clad panel attached to the back of the observatory.

The web track is repaired for the third time when it is close to its L2 point.

The first observations Webb will begin to make with these prospects in June. It is almost certain that Webb will revolutionize astronomical research. It observes and describes areas of space that have not been directly observed before.
