Hey Space Placers!
This is a huge step forward in preparing JWST for its launch on an Ariane 5 rocket from French Guiana In October 2021.
As stated in the NASA release, "The next series of milestones for Webb include a final sunshield fold and a final mirror deployment."
Milestones and actions will come quickly in order to meet the planned launch window.
THIS IS EXCITING!
