The NASA/ESA/CSA James Webb Space Telescope during a deployment test of its primary mirror into the same configuration it will have when in space.

The test, which involved commanding the spacecraft's internal systems to fully unfold and secure the 6.5 metre wide mirror, was performed in early March 2020 in a cleanroom at Northrop Grumman Space Systems in Redondo Beach, California.

The full deployment sequence can be seen in this video.
