James Webb Space Telescope On Its Way

Yesterday morning at 12:20 UTC, 7:20AM EST, the Ariane 5 carrying the JWST lifted off precisely on schedule.  

The video is from SciNews YouTube channel and was chosen somewhat randomly.  The official video they use is from NASA / ESA and is probably on many channels. 

The status of JWST at any moment can be checked at the Where is Webb? website by NASA.  The satellite is just 30 hours into its mission as I type and will take 30 days to reach it's orbit at the Earth-Moon L2 Lagrange point.  The satellite is currently around half the distance to the moon, and will pass our satellite tomorrow.  The high gain, Gimbaled Antenna Assembly (GAA), necessary for proper data rate transmissions back to Earth was deployed earlier today, and the next scheduled event is tomorrow - an early course correction engine burn.  

The Where is Webb? site includes a few big milestones in the deployment sequence as a time line, and the next big step after tomorrow's engine burn is the sun shield deployment on mission day three, our Tuesday.  An exact time for these events isn't given. 

This view, moments after Webb was separated from the Ariane upper stage, isn't the exact last view of the satellite, but will be among the last views.
