"According to ispace, the lander’s onboard sensors indicated a sharp rise in altitude when the craft passed over a 3-kilometer-high cliff. The cliff was later determined to be the rim of a crater. But the onboard computer had not been programmed for any cliff that high; it was told that in case of a large discrepancy in its expected position, the computer should assume something was wrong with the ship’s radar altimeter and disregard its input. "

are we still at the stage where we don't know about a crater rim that is 3KM high on the moon? I would assume that by now, imaging satellites have captured information like this?
