Years Of Careful Planning
This was no ordinary spur-of-the-moment expedition, however. In fact, they spent two years determining the best time and location for the dive. There is a cause for the delay. The reality is that we know more about the sky than we do about our own planet’s ocean bottom.
We Know Little About It
We now know more about the surface of Mars than we do about the ocean bottoms surrounding us. Allow us to put things into context. The distance between our planet and its neighbor is 140 million kilometers. The average depth of the ocean, on the other hand, is less than 12,000 feet, or roughly two miles!
