The James Webb Space Telescope is a space telescope developed by NASA, ESA and CSA to succeed the Hubble Space Telescope as NASA's flagship astrophysics mission. Its primary mirror, the Optical Telescope Element, is composed of 18 hexagonal mirror segments which combine to create a 6.5 m diameter mirror, considerably larger than Hubble's 2.4 m mirror. This will allow JWST to provide improved infrared resolution and sensitivity over Hubble, and will enable a broad range of investigations across the fields of astronomy and cosmology, including observing some of the most distant events and objects in the universe, such as the formation of the first galaxies.

Arianespace SA is a multinational company founded in 1980 as the world's first commercial launch service provider. It undertakes the production, operation, and marketing of the Ariane programme. Their vehicles launch exclusively from French Guiana in South America.INFO WIKI
NASA says a historical review of actions by former administrator James Webb confirmed its decision to keep the agency’s flagship space telescope named after him.
Experts from NASA and other institutions will be available by teleconference at 11 a.m. EST on Thursday, Nov. 17, to answer media questions about early science results from the agency’s James Webb Space Telescope.
Fresh images from the James Webb Space Telescope show the faraway planet Neptune hung amid a colorful tapestry of even more distant galaxies, the latest view from a now-regular flow of observations from astronomers’ new eye on the universe.
One part of an instrument on the James Webb Space Telescope is out of service temporarily, although project officials are confident it will not be a long-term problem.
