James Webb Space Telescope to launch in
After evaluating the findings of Webb's independent review board, NASA has established , as the new launch date for the James Webb Space Telescope.
The revised launch schedule accommodates performance challenges experienced during integration and testing of Webb's sunshield and propulsion system. More time is also needed to verify the integrity of the spacecraft element, join it to the telescope element, and perform environmental testing on the assembled observatory.
Rigorous evaluation of each part of Webb is crucial to mission success. When it is launched from French Guiana, the telescope will be folded inside the nose of an Ariane 5 rocket and subjected to high levels of vibration and noise. All of its sensitive components must be able to withstand launch and the harsh conditions of space.
The Canadian Space Agency continues to support the development of NASA's most ambitious and complex space observatory ever built. With the help of Canadian instruments, Webb will enable world-class science that sheds light on the most profound mysteries of our universe.
