Christmas morning at Europe's Spaceport
An Arianespace Ariane 5 carrying the James Webb Space Telescope lifted off from Europe's Spaceport in French Guiana at 12:20 UTC on 25 December 2021 — 7:20 a.m. Eastern, Christmas morning.
About three minutes in, the rocket jettisoned the payload fairing and then performed a special roll maneuver intended to keep solar radiation off the newly exposed observatory.
On its own after 27 minutes
Webb separated from the upper stage 27 minutes after launch and began traveling toward its planned orbit around the Sun–Earth L2 point, roughly 1.5 million kilometres (1 million miles) from Earth.
About 30 minutes after liftoff the solar array unfolded. The mission-operations center in Baltimore confirmed that the observatory was powered and in good condition.
The launch was not the arrival
Nothing reached L2 that day. The cruise took about a month, and Webb entered its L2 halo orbit in January 2022 — a large orbit around the point rather than a parking spot on it.
The roles behind the launch were equally distinct: Arianespace operated Ariane 5, ESA supplied the launch service and vehicle adaptations, and the Space Telescope Science Institute handled mission operations and science support rather than the rocket.
