I mean that there is no semantic comprehension or knowledge of 'Neil Armstrong' (as a specific person), 'land' (as an action), and 'Mars' (as a place). It's not a mishearing because computers don't mishear ASCII-inputs like we might do with auditory signal.

I get the same result when I Google 'when did Lance Armstrong land on the moon', 'when did Buzz Lightyear land on the moon', or 'when did Lance Armstrong land on Mars.'
