NASA has completed the vacuum testing of the telescope “James Webb”

The space telescope “James Webb” had a very long development process — its start is planned already for 2014, but due to several challenges the beginning of the mission was several times postponed until 2021. Recently space flight Center Goddard shared good news that the basic part of the long-awaited device have successfully passed the vacuum tests and the engineers only have to connect them together.

During these tests the component parts of the apparatus are placed in a vacuum chamber with the space environment in which to work the telescope. The telescope has been successfully tested in the past year, the Center Goddard. This year it was the turn of service of the machine — its performance in earth orbit has been tested by engineers of the military-industrial company Northrop Grumman.

Telescope “James Webb” almost ready to fly into space

The researchers announced that the first part without any problems and survived a sharp decrease in temperature from +102 to -148 degrees Celsius. Even with these drastic temperature changes, the researchers found no fault either in the electronics of the telescope nor its engines.

The test is successful, this means that the two parts of the telescope will soon be connected together. Subsequently, the device will be shipped to Kourou in French Guiana, where it will be launched into space using rocket Ariane 5.

Telescope “James Webb” is positioned as a replacement for the legendary Hubble who served for nearly three decades. The developers claim that it will be so powerful that will be able to see the bumblebee on the moon.
