when is the james webb telescope being launched
James Webb Space Telescope In December 2016, NASA announced that the JWST had passed major milestones, including completion of its primary mirror and integration of science instruments with the payload module, and had begun undergoing acoustic and extreme vibration testing to simulate launch conditions.[12][13] In March 2018, NASA delayed the JWST's launch an additional year after the telescope's sunshield ripped during a practice deployment and the sunshield's cables did not sufficiently tighten.[14] The JWST is currently scheduled to launch in May 2020.[3][4][15]
