A few nations have. The USSR, the US for Mars and Several nations have crashed things into the moon, unintentionally, including Israel and India. So maybe the problem wasn’t the metric system and something a lot more meaningful instead of what specific arbitrary unit of measurement you think is “better.”
e: Like look at this list: https://en.wikipedia.org/wiki/List_of_missions_to_Mars
There are more failures then successes, and only one of those failures was because of different units used for two related measurements. It’s weird to even bring it up as a point about the metric system.
