As the James Webb Space Telescope cruises in space, NASA engineers will perform the most challenging task-deploying sun visors. During the launch of the telescope, engineers have loosened and rolled up the sunshade to protect the thin layer.
The deployment of the cover takes about an hour. It requires the team to use electricity to activate the release device, execute the command to roll the cover to a fixed position, and expose the sunshade film to the space for the first time. After covering, the next step will be to deploy the middle arm of the sunshade before continuing to tighten the sunshade.
The team completed the deployment of momentum flaps on the tail of the observatory on Thursday, which will help reduce fuel consumption. Engineers will use fuel consumption throughout Weber’s life cycle to help keep the observatory’s direction in orbit. “When sunlight’s photons hit the surface of a large sun visor, they put pressure on the sun visor. If not properly balanced, this solar pressure will cause the observatory’s rotation and must be accommodated by its reaction wheels. The rear momentum flap will Continue to navigate the pressure of these photons, balance the sun visor and keep the observatory stable,” NASA said in a blog update.
