Meanwhile all our efforts are focused on finding if water was on Mars millions of years ago.
Because we're looking to colonize it. Finding out if Mars has ground water is important. As soon as we had satellite images of Ganymede, we knew there was water and plenty of it. Mars we weren't sure if it was frozen CO2 or water. Anything on Mars is a more pressing concern than what's on Ganymede, since all of its wonders and mysteries are below 95 miles of ice. Mars? Just a thin atmosphere and a bit of soil. Ganymede, while interesting, we're not going to find out much more about it until we go there ourselves with a big arse drill. Mars though, we're 20 years behind even the most liberal of estimates in the 60s.

Off topic question: What would it take to create a thicker atmosphere there?

I feel like I saw this in a movie. Just get Quaid to the reactor.

Earth, earth's moon, and Ganymede

Good pic.
It really is impressive how large the Moon is compared to the Earth. Unique in the Solar System.

I get what you are saying, but there is nothing that we can do to the Earth that will make it worse than Mars. The Red Planet has no magnetosphere.

On Mars? Do what we're doing here, but on steroids. Put as much greenhouse gases into the atmosphere as possible, and then once there's enough CO2 and heat on the surface, plant tons of trees. The magnetosphere is a problem though that we haven't exactly solved yet.

The total eclipse we experience from Earth may be a phenomena that is rarely seen elsewhere naturally in the cosmos. It's either the sun engulfs the moon, or the moon engulfs the sun when they cross paths. Nothing as far as we know quite has a moon and star that are roughly the same size when viewed from Earth. Our eclipse and relationship with our moon make's it entirely feasible that life may be more common than the relationship between our moon and planet. I can't help but stare in awe at the Moon when I think about its importance to our planet.

Damn space, you scary.

But here's the thing about putting a sizable portion of our population on a different planetary body: it saves us from extinction. If Earth nukes itself into an oblivion, but we still have sizable colonies on the Moon and Mars, then humanity lives on. Some variance of Interstellar is inevitable unless we start actively planning on being a space fairing species. I just hope it's not too late by the time humanity at large decides to stop mortgaging its future on bullshite that only lasts 4 years.

I think the surface area of the moon is the size of the USA stretching to Hawaii. It would fit in the pacific with just a little room to spare.
