James Webb Space Telescope: When will it be launched? What are its features? Check it Out!

The largest space Telescope ever, James Webb Space Telescope has been rolled out on its launchpad for its launch on Christmas day, 25th December 2021 at 5:50 pm.

It is the most awaited Telescope that has been assembled on top of Europe’s powerful Ariane-5 rocket which will help it to reach its orbit that is 1.5 kilometres away from Earth. The Ariane-5 rocket will be launched from Europe’s Spaceport in French Guiana.

The latest Telescope also has a perfectly controlled temperature and humidity range and is expected to bring all the answers about the Universe.
The various important features of the amazing Telescope are:

  • The centre of the telescope features a huge primary mirror, which is a concave structure of 21.5 feet (6.5 meters) width and is said to be made up of 18 smaller hexagonal mirrors. Moreover, it will also feature four scientific instruments which will help to image cosmic objects. For the protection of mirrors and instruments, it features a five-layer sun-shield to protect it from Sun’s heat and rays.


  • The Telescope will be placed around 930,000 miles from Earth in an orbit around the Sun. It will stay on Earth’s night side and will take about a month to reach its designated region in space or its second Lagrange point, or L2.


  • The Telescope is large enough to not fit in the rocket’s front cone, so it will be folded like origami and then after 30 minutes of rocket’s take-off, the energy supplying communications antenna and solar panels will be deployed and the sun’s shield will work to unfurled the components.


  • The telescope is being sent by the motive to find out about the cosmic history, the Bigg Bang and also about other planets outside our solar system. It will judge the atmospheres of other planets and find out if life is sustainable on them.

The construction of Webb’s started in 2004 and the planning was done even before that. It was delayed several times and now it is finally getting launched. It will bring a revolution in universal research and information.
