The world's largest space telescope to date, with equipment from DTU Space on board, is set to launch 25 December between 13:20 and 13:52 DK time.

Launch is as of now set for 25 December in the launch window 13:20-13:52 Danish time (CET).
Postponements occur for technical, human or weather reasons.
The launch has been postponed twice in December (from 16 and 24 December respectively).
The latest postponement is due to weather conditions.

Here at DTU Space, we are waiting with great excitement for the launch of the James Webb Space Telescope (JWST) with flight VA256 from the European spaceport in French Guiana. We have provided equipment for the mission, and take part in the scientific work after launch as well.

The telescope is on board the European Ariane 5 rocket, which is now ready to bring it into orbit 1.5 million km. from Earth.
But as is always the case with missions to be sent into space, everything must work perfectly as there are very few options for repairing or adjusting the equipment after launch. As it is also among the largest space missions so far in this century with a total value of about 65 billion. DKK, no chances are taken.

The European Space Agency ESA and American NASA are responsible for the project, which is a major international collaboration.
