Mission Brief

ESA's Comet Interceptor consists of three spacecraft which will be positioned at the Sun-Earth Lagrange point L2, where they will wait for a long-period comet or an interstellar object to come by. Once the desired target appears, the spacecraft will separate and perform a flyby of the target, compiling a detailed 3D profile of a comet.
