After more than 20 years of construction, the James Webb Space Telescope is complete and expected to launch within two years. NASA's James Webb Space Telescope is an $8.8 billion space observatory built to observe the infrared universe like never before. NASA hosted a news conference to announce the milestone at the agency's Goddard Space Flight Center in Maryland. The full telescope, with a 21.3-foot mirror assembly, is too large to launch fully extended, so the telescope will be carefully furled during launch and will have to unfold over the course of two weeks once it's in space.
This is a great advance in science and technology as nothing quite like this has been attempted before. This reminds me of the industrial revolution, where bold new advances in technology were being discovered at an unprecedented time in earths history. With all the new technology being developed everyday, you could argue that the industrial revolution never really ended.
