📞 Hello Webb? It's us, Earth!

Our team just deployed the gimbaled antenna assembly, which includes Webb’s high-data-rate dish antenna. This antenna will be used to send at least 28.6 Gbytes of data down from the observatory, twice a day: https://go.nasa.gov/3qnXZQt

James Webb Space Telescope separation recap

This real-time video shows the
separation of the James Webb Space Telescope from the Ariane 5 launch vehicle and the subsequent solar array deployment without transmission artefacts.

Thanks to Ariane 5’s highly precise launch trajectory Webb’s solar array was able to deploy soon after separation from the Ariane 5, capturing sunlight to power the observatory.

This video shows the view from Ariane 5’s upper stage, taken by a camera manufactured by Irish company Réaltra Space Systems Engineering.
