After design, manufacture, and initial laboratory  characterization, such components are being prepared for on-sky tests, to  validate them for use in real instruments.

It carries four scientific instruments designed to unlock more secrets from the universe:  With JWST, we will be able to look farther into the past than ever before and observe the first galaxies, we will learn more about the birth of stars and planets, and we will be able to study planets outside our own solar system.[[BR]][[BR]]The technology of the satellite itself is unique and a masterpiece of engineering. For example, the observatory - which is the size of a tennis court - had to be folded up for launch on the Ariane 5 rocket and then unfolded again fully automatically in space. Development of JWST began back in 1996, construction itself in 2004, with the four instruments ready between 2012 and 2013 and the entire satellite in 2021.[[BR]][[BR]]In this talk, I will give an overview of the fascinating history of JWST: From the idea to the construction and test, to the launch and the currently ongoing commissioning phase.[[BR]][[BR]]Presentation: German[[BR]]Slides: English[[BR]]Questions: German, English ||
