    About this moment

    Ariane 64: Comet Interceptor is expected August 2028. The exact day has not been announced yet.

    Arianespace is preparing to launch Comet Interceptor on an Ariane 64 from Guiana Space Centre, French Guiana. 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. Launch is expected in August 2028 and no firm date has been announced yet.

    This listing uses an approximate period. An exact day has not been confirmed.
