Webb is Nasa’s successor to the ageing Hubble space telescope. Work on it began way back in 1996. Back then, it was called the Next Generation space telescope. It was forecast to cost $500m (£363m) and was set for launch in 2007. Nasa has completed the final tests of the James Webb space telescope and is now preparing it for transportation to the launch site in Kourou, French Guiana. Now, with the successful completion of the final set of tests, there is nothing left to do but launch the telescope and see if it all works as planned. Webb is the world’s most complex space science observatory. It consists of a 6.5-metre mirror and a tennis-court-sized sunshield, all of which will be folded into the nose-cone of a European Space Agency Ariane 5 rocket for launch later this year. What is your thoughts on the space sicnec observatory launch by NASA?
