ATIG Members-

Following an on-time launch at 12:20 PM UT on Christmas Day, the James Webb Space Telescope (JWST) is undergoing successful initial deployment activities.  Further critical deployment milestones are planned over the coming weeks (ref. https://www.floridatoday.com/story/tech/science/space/2021/12/25/nasas-james-webb-telescope-launches-kicking-off-nail-biting-mission/9006733002/).  This on-time launch renders reasonably valid a planned trajectory for JWST's first month in space as posted to JPL's Horizons server on 23 December 2021.  The attached JPEG graphic plots Earth-centered motion of JWST, together with that of the Moon, during the month following launch.

Happy and healthy holidays to all!
