The James Webb Space Tele­scope (JWST) was orig­i­nally sup­posed to be launched around 2007, but it is now de­layed un­til at least 2021. Some of this is due to sim­ple build­ing mis­takes like loose bolts, but mostly it’s be­cause the JWST in­volves lots of new ideas and tech­nol­ogy that is far more ad­vanced than the old Hub­ble Space Tele­scope. In­vent­ing and test­ing these new tech­nolo­gies and ideas has taken longer than peo­ple first ex­pected, but this isn’t sur­pris­ing be­cause ad­vanced projects like this are of­ten late as they are in­tended to push science for­ward by tack­ling the un­known and solv­ing dif­fi­cult prob­lems.

The James Webb Space Tele­scope is shown here be­ing tested to en­sure it sur­vives the tem­per­a­ture ex­tremes in space
