James Webb Telescope finds the facts on “Birth of our universe”; Completes its journey in the orbit

The James Web Telescope has completed its 15,00,000 km long journey in the orbit, and reached its destination today. The telescope was launched from Europe’s Spaceport in French Guiana on board the powerful Ariane-5 rocket on December 25, to discover the facts on the origin of our universe.

As engineers prep it for a terminal correction burn that will place it in its desired orbit, the world’s most powerful observatory is set to arrive the second Lagrange point L2. The Mid Course Correction Burn will correct any residual trajectory errors during the long journey and adjust the final L2 orbit. The Telescope was launched with 3 mid-course corrections, viz; MCC-1a, MCC-1b and MCC-2.
Among these, the third one MCC-2 sent the telescope into its L2 halo orbit. The James Webb Telescope is launched on a direct path to an orbit around the 2nd Sun-Earth Lagrange Point L2, but it require to form its own mid-course thrust correction manoeuvres to reach the particular destination in the space.
James Webb Telescope’s journey :
The telescope travelled to a destination called the second Lagrange point. These are positions in space, where objects sent, tend to stay put. The gravitational pull of two large masses exactly equal to the centripetal force at Lagrage points. This is essential  for a small object to move with them. These points in space can be used by spacecraft to reduce the fuel consumption needed to remain in position.
What the telescope done at L2? :
After the insertion of telescope into orbit at the second Lagrange point, the team will continue its cool down following a month-long journey from earth. The cooling down will be faster since the telescope is now stable in its orbit and the instruments are shaded from the heat of the sun, moon and earth by the sun shields. The telescope will observe the early universe going as far back as the big bang itself, facing the dark side of earth.
