Watch the European Space Agency launch LISA Pathfinder

Albert Einstein predicted gravitational waves as a part of his Theory of Relativity, and in order to better understand them, the ESA is about to launch its Lisa Pathfinder mission. This is a small-scale test run for the actual measuring equipment slated to launch in 2034, intended to prove that its instruments can reach the required level of precision. The launch will take place shortly from the Kourou spaceport in French Guiana, and you can watch the video live streamed right here.
