NASA Sets Coverage, Invites Public to View Webb Telescope Launch
KOUROU, French Guiana (NASA PR) — NASA will provide coverage of prelaunch, launch, and postlaunch activities for the James Webb Space Telescope, the world’s largest and most powerful space science telescope.
Webb is targeted to launch at 7:20 a.m. EST Friday, Dec. 24, on an Arianespace Ariane 5 rocket from Europe’s Spaceport in Kourou, French Guiana, on the northeastern coast of South America.
Live launch coverage in English will begin at 6 a.m. on NASA TV, the NASA app, and the agency’s website. The public can also watch live on Facebook, Twitter, YouTube, Twitch, and Daily Motion. NASA also will offer a launch broadcast in Spanish beginning at 6:30 a.m. on the agency’s website and Spanish-language social media accounts. NASA will hold a prelaunch media briefing at 2 p.m. on Tuesday, Dec. 21, and a postlaunch news conference approximately 30 minutes after the live launch broadcast ends on Friday, Dec. 24.
The Webb mission, an international partnership with ESA (European Space Agency) and the Canadian Space Agency, will explore every phase of cosmic history – from within the solar system to the most distant observable galaxies in the early universe, and everything in between. Webb will reveal new and unexpected discoveries and help humanity understand the origins of the universe and our place in it.
