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. 0 of the 1 record are still active, leaving 1 concluded. A partial success is a distinct recorded outcome, so it is not counted in the numerator, but it stays in the denominator.

These records in the directory

The directory's destination filter is a category taxonomy, and it has no 25143 Itokawa key: these records are filed under asteroid alongside every other body of that kind. This page is where the catalog counts 25143 Itokawa on its own.

The explorer draws a flight path only where a trajectory dataset is committed, and only where that dataset records an encounter with this body. A record above does carry one, but none of them encounters 25143 Itokawa, so the explorer has no 25143 Itokawa path to draw and this page offers no link to one.
