Hey, Space Placers!
This is the core stage of the Ariane 5 rocket that will launch James Webb Space Telescope (JWST) into orbit. The core stage will be mated to two solid rocket boosters and the whole stack will be checked out and certified for launch, currently scheduled for December 18, 2021.
JWST is undergoing check out and preparations for eventually mating to the Ariane 5.
Time to LIGHT THIS CANDLE!!!
