The James Webb Space Telescope lifted off on an Ariane 5 rocket from Europe's Spaceport in French Guiana, at 13:20 CET on 25 December 2021 on its exciting mission to unlock the secrets of the Universe.

This timelapse shows highlights of the launch campaign from the arrival of Webb in French Guiana through to liftoff.

Every launch requires meticulous planning and preparation. For Webb, this process began about 15 years ago. Webb arrived from California on board the MN Colibri which sailed the Panama Canal to Pariacabo harbor in French Guiana. The shallow Kourou river was specially dredged to ensure a clear passage and the vessel followed high tide to safely reach port on 12 October 2021.

Though the telescope weighs only six tons, it was more than 10.5 m high and almost 4.5 m wide when folded. At Europe's Spaceport it was unpacked inside a dedicated spacecraft preparation facility fitted with walls of air filters to protect the telescope from contamination during preparations for launch.

After its arrival in the final assembly building, Webb was lifted slowly about 40 m high and then carefully maneuvered on top of Ariane 5—one of the most delicate operations during the entire launch campaign.

In October 2017, the interstellar object 'Oumuamua passed through our solar system, leaving many questions in its wake. Not only was it the first object of its kind ever observed, but the limited data astronomers obtained as it shot out of our solar system left them all scratching their heads. Even today, almost five years after this interstellar visitor made its flyby, scientists are still uncertain about its true nature and origins. In the end, the only way to get real answers from 'Oumuamua is to catch up with it.

Interestingly enough, there are many proposals on the table for missions that could do just that. Consider Project Lyra, a proposal by the Institute for Interstellar Studies (i4is), which would rely on advanced propulsions technology to rendezvous with interstellar objects (ISOs) and study them.
