We’re Planning Moon Missions But We’ve Only Mapped 20 Percent of the Ocean Floor

We should probably finish exploring our own world first.

Slow and Steady

An international team of scientists funded by billionaire investor Victor Vescovo recently announced that it’s mapped about 20 percent of the ocean floor — and the fact that that’s a major improvement over how little had previously been explored reveals just how much of our planet remains shrouded in mystery.

According to the team’s update, the Seabed 2030 project added an area just about the size of the United States to its map of the ocean floor. That’s actually a pretty significant slowdown in the overall mission to map out the entire global ocean floor by 2030, Live Science reports, due to pandemic-related hiccups.

Given those low numbers, it seems almost comical how low of a priority it is to map out, to say nothing of actually understanding our own planet compared to, say, exploring the surface of the Moon and Mars.

Looking Inward

To be fair, reaching and then traversing the ocean floor is an exceptionally difficult engineering challenge, and scientists can learn a lot about the Moon by craning their necks back and looking at it.

Still, as Live Science notes, building a map of the ocean floor would give scientists an invaluable new tool as they try to understand the Earth, as well as how the ocean influences and is influenced by the changing climate. Given the horrors of climate change that likely await us, that seems like it ought to be a priority.

Tick Tock

It may seem like seafloor and lunar exploration is a bit of a false equivalency, but there’s good reason to make mapping out and studying the vast, unknown swathes of ocean floor a higher priority. Unless you know something that we don’t, the Moon isn’t going anywhere any time soon.

But the mining industry is actively digging up chunks of the seafloor, causing an unknowable amount of damage to the environment below and potentially rendering entire ecosystems lost to science before they’re ever found in the first place.
