The post-launch set-up of the new James Webb telescope has gone very well.'

Bill Ochs, the NASA project manager, said tightening up the sunshade's five hair-thin layers, carefully pulling them taut with motor-driven cables running through multiple pulleys, likely would take three days to complete.
