The only event found on this day was the launch of the James Webb Telescope in 2021.  The photos today include that launch, the telescope assembly after environmental testing, and a photo of the NIRCam instrument, built by LM in Palo Alto.  I have also included the NIRCam filter spectrum chart and a diagram of NIRCam. All of these images and diagrams were cleared for public release by NASA/GSFC. 

December 25 – Arianespace’s Ariane 5 rocket launches with NASA’s James Webb Space Telescope onboard, Saturday, Dec. 25, 2021, from the ELA-3 Launch Zone of Europe’s Spaceport at the Guiana Space Centre in Kourou, French Guiana. The James Webb Space Telescope (sometimes called JWST or Webb) is a large infrared telescope with a 21.3 foot (6.5 meter) primary mirror. The observatory will study every phase of cosmic history—from within our solar system to the most distant observable galaxies in the early universe. Photo Credit: (NASA/Bill Ingalls)
