According to the Guardian,The launch of the US$10 billion James Webb Space Telescope was once again delayed.Because an accident occurred during the final preparations for placing the telescope on top of the launch vehicle. The telescope was originally scheduled to be put into orbit on December 18, but it will not be launched before December 22.
The space telescope has been transported to the Kuru Space Port in French Guiana, where it will be launched using the Ariane 5 carrier rocket provided by the European Space Agency (ESA). The project is an international cooperation project between NASA, ESA and the Canadian Space Agency.
At the time of the incident, technicians were preparing to install the James Webb Space Telescope on the launch vehicle adapter, and then use it to fix the telescope on the upper stage of the rocket. According to NASA, “a sudden, unplanned release of entrainment” occurred. The entrainment fixes the spacecraft on the launch adapter and then releases it in orbit, separating the spacecraft from the rocket. This unplanned release caused the telescope to vibrate.
In order to be absolutely certain that the telescope is still in perfect condition, NASA has convened an anomaly committee to investigate and conduct additional tests on the telescope to ensure that there is no damage. Once this work is completed, assuming that the telescope is not damaged, preparations for launch will resume.
