Success rate

100%

Active missions are excluded from the success rate: a live mission has no outcome yet, so counting it would report a rate the records do not support. 1 of the 3 records is still active, leaving 2 concluded. A partial success is a distinct recorded outcome, so it is not counted in the numerator, but it stays in the denominator.

A joint mission is counted under every agency its record lists, so these figures need not add up to 3.

A mission can carry several types, so these figures need not add up either. Types no mission here carries are omitted.

These records in the directory

The directory's destination filter is a category taxonomy, and it has no Dimorphos key: these records are filed under asteroid alongside every other body of that kind. This page is where the catalog counts Dimorphos on its own.

The explorer draws a flight path only where a trajectory dataset is committed. Mission inspection shows one spacecraft at a time, so this link opens the earliest available mission.
