Comet Interceptor is an ESA mission with JAXA participation designed to examine a relatively pristine comet, potentially an interstellar object, whose identity is not yet selected. A main spacecraft and two probes will wait together near Sun-Earth L2, then travel to a suitable target and separate for simultaneous measurements from three viewpoints. Unlike repeatedly heated short-period comets visited by earlier missions, the target should preserve less-altered material from its formation. ESA currently describes a launch window spanning late 2028 or early 2029.
Schedule, status, and mission updates. Time-based alerts will start when a time is available.
