I've always been more excited about a Moon colony than a Mars one. I mean, compared to Mars, the Moon is ridiculously close. Many of the same benefits Musk seeks (backup for Civilization, excitement) for a fraction of the cost. Low gravity and atmosphere on a dome would be more complicated, but again, compared to Mars, it's right there . It would be a more humble and realistic first step, IMO.

So, why is Elon Musk not excited about Moon?

It makes much more sense to use the moon as a stepping rock. At least my KSP experience has taught me that :)

Every experienced KSP player uses Minmus of course, not the Mun.

My experience in KSP usually ends with an explosion

Remember pop-unders? I don't miss closing my browser and finding a dozen ads hiding under the window.

Of course in that time you had no tab indicator to nicely tell you who was playing sound. Nothing quite like those search that took you on sketchy websites and their porn pop under blasting orgasmic noises in your home / office while you frantically try to find who does that (and then close everything because it's taking too long). "The good old time", as they say.

Sound indicators ... that time? Like a year ago?

Unrelated to the article, but WOW did anyone else see the giant full view height ad video at the top? I have ad blocker off for NatGeo. It's followed by a giant banner. I can't imagine how much crazier ads have been getting and most of us don't even notice 'cause we have ad blocker.

Wow yeah I instantly hit "Back" and have now blacklisted national geographic. Seriously, national geographic? Thing's have gotten that bad I am now blocking NG? Sigh. I liked grubbers dubbing of a "dickbar" but this kind of ad deserves its own moniker. PrickPage?

NatGeo was purchased by FOX recently, if that insight helps...

I rather have Civilization backup in Mars. If the Earth goes, the Moon wouldn't be in a very good shape. Just like I wouldn't go hide in the kitchen, while the living room is burning down.

I think the 0-step should be a sort of treaty to decide which set of laws and jurisdiction should have a space colony on the moon. Not easily solvable

It wouldn't really be relevant. For why, read The Moon is a Harsh Mistress. TLDR: The moon colony will be able to make its own rules and keep earth at bay.

Will be in how much time? Considering the first man who went to the moon needed to place a national flag on it asap, I think we are risking a serious conflict and IF we could avoid it better we do whatever is possible BEFORE having people fighting directly on the moon.

In terms of distance, sure. In terms of delta-v, the budget for the moon is upwards of 50% that for Mars. EDIT: The 50% figure is from memory, and upon further reflection is probably not quite right, so take it with a grain of salt. I just wanted to point out that distance is not the only relevant metric.

>The 50% figure is from memory, and upon further reflection is probably not quite right, so take it with a grain of salt. You're actually underestimating. Mars has an atmosphere, so spacecraft can use aerobraking to significantly reduce the delta-v required to get there. The moon has no such benefit — propulsion is required all the way to the surface. The advantage of the moon, of course, is that it's not limited to…

You need a far bigger (heavier) craft to get to Mars. You'll need years worth of food, water, air, you'll need radiation shielding, much more space per crewmember, more redundant systems and backups, etc.

Look at the size of the Apollo.

Inasmuch as Mars with our current technology offers no back up for civilization, the same can certainly be said for the moon. I would argue over that the moon actually has some benefits Mars lacks, in addition to proximity it has a much lesser gravitational field and therefore a much lower delta V. Moon colony could realistically jumpstart space and vacuum industries beyond LEO, and frankly it would probably give us…

Mars has atmosphere for aerobraking and ISRU possibilities that the moon does not. In many ways, it is much more practical from a spaceflight standpoint. That's not to say that there aren't possibilities for both, but Mars is seen as the preferred choice for a variety of sound reasons.

You can also rotate the crew on the moon. Can send things to the moon you didn't anticipate. Can send replacement/repair parts.

Can't do that for Mars.
