On Wednesday, Nov. 17, NASA Headquarters held its final review for the mission prior to launch. A week later, on Nov. 24, a review committee approved Webb’s transition to the next stage in its preparations for launch. This week we’ve asked NASA’s Randy Kimble, Webb’s integration, test, and commissioning project scientist, to tell us how things are going at the launch site:at the Arianespace launch facilities in Kourou, French Guiana. This is an important step in the path toward launch.
“Propellant loading was the final major operation for the observatory itself, before it moves to the Final Assembly Building for integration with the Ariane 5 launch vehicle. “From Eve and Alan, ‘Our NASA contamination control engineers and technicians have transformed facilities that are not designed for scientific spacecraft into well-controlled clean rooms not just with HEPA filters, but by covering, cleaning, removing, bagging, and sealing over items incompatible with Webb’s stringent cleanliness requirements, and then cleaning every surface daily.’ The launch site facilities that Webb has encountered so far have all performed well, thanks to these efforts.
