ESA’s SWARM satellites are successfully launched from the Plesetsk cosmodrome in northern Russia this morning in what has to be one of the prettiest launches I’ve seen in a long while. The launch went off perfectly at 12:03 UTC. ESA has since acquired signals from all three satellites so it would sound as if things are going smoothly.
The mission is going to be a very interesting one: study the magnetic field. Sounds simple, but it’s not so much. For example we know the magnetic field is basically set up by the molten core of iron at the Earth’s center.
