NASA Completes Vacuum Testing of James Webb Telescope

Space telescope "James Webb" was verya long development process - its launch was already planned for 2014, but due to a number of problems encountered, the beginning of the mission was postponed several times until 2021. Recently, the Goddard Space Flight Center shared the good news that the main parts of the long-awaited device had successfully passed the vacuum tests, and the engineers had only to combine them.

During these tests, the components of the apparatusplaced in a vacuum chamber with the space conditions in which to operate the telescope. The telescope itself was successfully tested last year at the Goddard Space Flight Center. This year it was the turn of the service part of the device - its performance in the conditions of the near-earth orbit was checked by engineers of the military-industrial company Northrop Grumman.

Telescope "James Webb" is almost ready to fly into space

The researchers announced that the service part withoutspecial problems withstood a sharp decrease in temperature from +102 to -148 degrees Celsius. Even with such sharp temperature changes, the researchers found no faults either in the telescope electronics or in its engines.

The tests ended successfully, which means thatThe two parts of the telescope will soon be joined together. Subsequently, the device will be sent to the Kourou space center in French Guiana, from where it will be launched into space using the Ariane 5 launch vehicle.

Telescope "James Webb" is positioned as a replacementthe legendary Hubble, which has served for nearly three decades. The developers claim that it will be so powerful that it can see the bumblebee on the moon.
