The james webb space telescope is peering into the past to unlock the mysteries of our universe Learn about the technical details of this ambitious mission. As seen from earth at midnight, the webb orbit completes a large loop of 1,000,000 kilometers in diameter twice a year. James webb space telescope (jwst), satellite observatory designed as the successor to the hubble space telescope (hst) and launched by an ariane 5 rocket in 2021 The jwst has a mirror 6.5 meters (21.3 feet) in diameter, seven times larger than that of the hst. Its mass is about 6,500 kg, and its sunshield is the size of a tennis court
In order to launch it into space, the telescope had to be folded up to fit inside the fairing of the ariane 5 rocket that launched it into space on the morning of december 25, 2021. Understanding the dimensions of the jwst is essential to grasp how its size and structure contribute to its operational capabilities This section will serve as the foundation for exploring the implications of these dimensions on our grasp of the cosmos. On earth, webb tipped the scales at more than 13,000 pounds—just about equal to the weight of an adult african elephant
