T+3 days is when the forward and aft Unitized Pallet Structure (UPS) of the observatory's sunshield deploys. The UPS pallets carry and support the five membranes that make up the sunshield. During the deployments of the UPS, key release devices are activated, and electronics and software that support the UPS motors are configured before the deployments. What's more, the deployment of the forward UPS pallet marks the beginning of all major deployments.
