'Perfect' James Webb telescope on track for launch
The successor to the Hubble Space Telescope is on track for a launch in mid-December, officials say.The James Webb Space Telescope (JWST) has cost $10bn to develop and will be one of the grand scientific endeavours of the 21st Century.
Its mission is to image the very first stars to shine in the Universe.
Webb will be sent to orbit on an Ariane rocket from French Guiana. Engineers there began assembling the vehicle's various components over the weekend.
The Ariane's 30m-tall main core stage was lifted into the vertical to allow its side boosters to be attached. The rocket's upper-stage, which will drive the latter part of Webb's ascent, will be bolted on in a few days.
JWST itself is likely to be placed atop the rocket a week before lift-off on 18 December.
