James Webb Space Telescope unfurls massive sunshield in major deployment milestone

With Webb’s Mid-Booms Extended, Sunshield Takes Shape

Starboard boom deployed! The sunshield has now taken on its diamond shape in space!

Webb has successfully deployed the port sunshield midboom! Delay was caused by sunshield cover switches not deploying when opened. Gyroscopes confirmed good opening, and port midboom extended without a hitch!
