The James Webb space Telescope was launched 

Launch Vehicle

The James Webb space telescope was launched on an associate degree Ariane five rocket. The launch vehicle and launch website are a part of the EU house Agency’s contribution to the mission. The Ariane five is one among the world’s most reliable launch vehicles and was chosen for a mixture of reliableness (it was the sole launch vehicle that met NASA’s necessities for launching a mission like Webb) and for the worth it brings via our international partnership.


Launch Location

Webb was launched from Arianespace’s ELA-3 launch complicated at Europe’s Spaceport situated close to Kourou, French geographic region. it’s useful for launch sites to be situated close to the equator – the spin of the planet will assist in giving an extra push. The surface of the planet at the equator is moving at 1670 km/hr.


Additional Details

The Launch phase has three primary components:


  1. Launch Vehicle: associate degree Ariane five with the refrigerant higher stage. Provided within the single launch configuration, with an extended payload fairing providing a most four. 57-meter static diameter and useable length of sixteen.19 meters.


  1. Payload Adapter, comprising the Cone 3936 and ACU 2624 lower cylinder and clamp-band, provides the separating mechanical and electrical interface between the Webb Observatory and therefore the Launch Vehicle.


  1. Launch campaign preparation and launch campaign. The launch campaign preparation and launch campaign is the mutual responsibility of the National Aeronautics and Space Administration, ESA, John Howard Northrop Grumman and Arianespace.


Webb Launch Configuration

For the telescope to suit into the rocket, it should fold up. These pictures show however it fits into the rocket fairing. pictures courtesy of your website.

Post Launch readying

After launch, the telescope deploys on its 29-day, million-mile journey bent on the second Lagrange purpose (L2). This video shows the readying procedure, timeline, and placement of the satellite throughout readying. additional regarding the telescope’s final orbit around L2.
