      Tower test: complete ✅ #NASAWebb testing teams successfully extended and deployed a critical part of the observatory called the Deployable Tower Assembly. During the test, the tower was extended in the same way it will once in space! More: https://go.nasa.gov/30wgNl7 pic.twitter.com/8COEWGVPKV

      Humans for scale. Webb's deployable tower which connects the upper and lower sections of the spacecraft is shown here fully extended. During the recently successful test the tower was commanded to deploy and extend 48 inches (1.2 meters) over the course of about 5 hours. #JWSTpic.twitter.com/QFjL2uIYxO

          And this picture shows the deployable tower fully stowed and compacted. By creating a space between the two, it allows for Webb’s active and passive cooling systems to bring its mirrors and sensors down to staggeringly cold temperatures required to perform optimal science.pic.twitter.com/MQyB92B3fE

          In order to do the test, Webb's 6.5 meter (21 feet 4 inch) primary mirror had to be folded into a much smaller size. This picture shows one of the mirror's side panels latched and stowed with the other soon to follow.pic.twitter.com/aLcxl9Vpwx

          Now that the observatory has been fully assembled, the difficulty and complexity of both testing and work on Webb has increased significantly. Special tools, lifts and cranes are used to provide engineers and technicians with the best angle of approach to do their work.pic.twitter.com/LiGd6wk29B

          Simulating the zero-gravity environment Webb will operate in, engineers employed an innovative series of pulleys, counterbalances and a special crane called a gravity-negation system that perfectly offloaded all of the effects of Earth’s gravity on the observatory.pic.twitter.com/vp6tYkxoIk

          On average, how many times are such tests performed before launch?
