when will the james webb telescope be operating
James Webb Space Telescope The James Webb Space Telescope (JWST) is a space telescope that is part of NASA's Next Generation Space Telescope program, developed in coordination between NASA, the European Space Agency, and the Canadian Space Agency.[5] It is scheduled to launch in 2019[3] and will be located near the Earthâ€“Sun L2 lagrangian point. The telescope will offer unprecedented resolution and sensitivity from the long-wavelength (orange to red) visible light through the mid-infrared (0.6 to 27 micrometer) range.
Chandra X-ray Observatory The Chandra X-ray Observatory (CXO), previously known as the Advanced X-ray Astrophysics Facility (AXAF), is a Flagship-class space observatory launched on STS-93 by NASA on July 23, 1999. Chandra is sensitive to X-ray sources 100 times fainter than any previous X-ray telescope, enabled by the high angular resolution of its mirrors. Since the Earth's atmosphere absorbs the vast majority of X-rays, they are not detectable from Earth-based telescopes; therefore space-based telescopes are required to make these observations. Chandra is an Earth satellite in a 64-hour orbit, and its mission is ongoing as of 2018[update].
