In our episode about terraforming Venus, we talked about cooling the planet with a giant sunshade, and then hand-wavingly bind up all that carbon dioxide.

We did the same with Mars, filling the atmosphere with greenhouse gasses to warm it up, and releasing the planet’s vast stores of C02 to thicken the atmosphere. Then just crash in a few comets worth of water and upgrade them to to a 3 star resort.

We’re pitching this as a new series on the Discovery Network, called “Flip My Planet – Canada”.

Now let’s turn our imagination towards another rockball that is really more of a fixer-upper: The Moon. I know, you never even thought of the Moon as a place that we could possibly terra-renovate. Go ahead and imagine with me all the possibilities of a verdant green and blue little world hanging in the night sky. Doesn’t that sound great?

So, what does it take? Do we tear it down and just use the orbital lot space? Should we raise it up and lay a new foundation? Or could we get away with a few coats of paint and adding an atrium on the backside?

Fortunately for me, scientist and sci-fi author Gregory “Planetary Makeover” Benford has already done the math.

Let’s take a look at what we’d need to get the Moon habitable. For starters, the fact that the Moon is so close to Earth is a huge advantage. This is like living on the same block as a Home Depot, and we won’t have to travel far to get supplies and equipment to and from our project.

We’re going to need an atmosphere thick enough to breathe and trap in the Sun’s heat. This takes wild comet capture and harvest, tear them apart and smash them into the Moon.

Benford notes that you probably want be careful not to let an entire comet collide with the Moon because it might spray your primary investment home with debris and do a little damage to the resale value, or potentially annoy your tenants.

This could get bad enough that we’d have to terraform Earth to get it livable again, and you’d need to bring in Mike Holmes to publicly shame us and put our primary residence back in order.

After you’d splattered a few comets on the Moon, it would have an atmosphere almost immediately. The transfer of momentum from the comet chunks would get the Moon rotating more rapidly.

If you invest a little more in your planning stage, you could get the Moon spinning once every 24 hours, and even tilt its axis to get seasons. Benford estimates that we’d need 100 Halley’s mass comets to get the job done. This might sound like a pretty tall order, but it’s tiny compared to number of comets we’d need for your Mars or Venus real estate scheme.

The maintenance and upkeep isn’t going to be without its challenges. Low gravity on the Moon means that it can’t hold onto its atmosphere for longer than a few thousand years.

Once you got the process going, you’d need to be constantly replenishing our your orbital cottage with fresh atmosphere. Fortunately, we’ve got a whole Solar System’s worth of ice to exploit.

The benefits of a terraformed summer home on the Moon are numerous. For example, if the Moon had an atmosphere as thick as the Earth’s, you could strap on a pair of wings and fly around in the 1/6th gravity.

The enormous gravity of the Earth would pull the Moon’s oceans around the planet with 20 meter tides. You could surf the tide for kilometers as it washes across the surface in a miniature version of the shallow water scene in Interstellar.

This might be the greatest sponsorship opportunity for GoPro of all time. Look out Kiteboarding, you’re about to get more extreme.

Everyone always wants to talk about terraforming Venus or Mars. Let them be, that’s too much work. The next time someone brings it up at D&D night, you can blow their minds with your well crafted argument on why we want to start with the Moon.
