Reply to comment by Major_Lennox in TIL More than 80 percent of the ocean has never been mapped, explored, or even seen by humans and as a result, we know more about the surface of Mars than Earth by [deleted]

Seriously dumb headline. 100% has been mapped. One has to just qualify that with "not mapped to five meter resolution" etc. It's like saying a city hasn't been mapped because they don't have the location of every tree.
