The James Webb telescope will be the world biggest and most powerful telescope when it launches in 2018. Nasa describes it as a'time machine' that can peer back 200 million years after the Big Bang. This week, Nasa engineers in Maryland got a little closer to launch with the completion of testing on its science cameras and the installation of the final flight mirrors. NASA's James Webb Space Telescope completed primary mirror sits in the cleanroom at NASA Goddard Space Flight Center, and supported over it on the tripod is the secondary mirror After over a year of planning, nearly four months of final cold testing and monitoring, the testing on the science instruments module of the observatory was completed.
