It's been a decade since it was announced, but the Euclid mission to build a 3D map of the universe is finally getting close to launch with the spacecraft landing in Florida ahead of an expected July liftoff. The Euclid mission will send the eponymous probe to Earth-Sun Lagrange point 2 - the same spot as NASA's James Webb Telescope , where it will observe more than a third of the sky and detect galaxies as distant as 10 billion light years away. Lagrange points are positions in space where Earth and the Sun's gravitational influences are equal, resulting in objects placed there largely staying put relative to the Earth and Sun.
