The operation is very complicated. It requires the skill, completeness and precision of many mechanisms: tests are complex on Earth, making it impossible to simulate conditions in space. But for Americans, “failure is not an option,” laughed Oliver Berne, an astrophysicist at the National Center for Scientific Research. He is responsible for one of the observation programs Of the James Webb Telescope. And when we reminded him of December 18th, he was already cold.

To him, there are so many surprises and it certainly is. James Webb, a $ 10 billion project, simply does not allow the observation of new galaxies, planets, stars, and nebulae. It becomes a journey into the history of our existence: “We try to understand how the first stars were created after the Big Bang (…) (…) One of the goals is to understand where we came from. “

The web is another big step for humanity. A revolution. Its development began in 1996. 25 years later, the project is visionary and very ambitious, Despite technical hurdles. “It’s so big, you have to fold it to bring it into the Ariane 5 rocket that will launch it into space. So it’s an origami telescope, a telescope that folds completely to enter the rocket and it opens once in space,” the researcher explained.

The entire team oversees the work of extending the James Webb Telescope for several days. Equipped with a mirror with a diameter of more than 6 meters, it allows observation in the infrared and acts as a detector of previously invisible lights. The abstraction of these lights makes it possible to discover an entire universe that has not been explored to this day.

From the first month of entering space, the telescope must reach The second Lagrange point is 1.5 million kilometers from Earth. And Oliver Berney told us: “What I expect from this project is to impress, to amaze, to amaze, to discover things I never expected. “
