Alot of people react negatively to overt emotional manipulation. Musk's live stream is called "Making Humans a Multiplanetary Species." The only actual information in his talk was about the new line of rockets he's building. Transportation is certainly Musk's specialty, but with the information given combined with what we already know about the man's companies, he cannot even begin to address the scope of the opening…

If getting stuff to Mars becomes cheap enough, then the rest becomes pretty easy. He's proposing a system for getting stuff to Mars cheaply enough. Characterizing this as "emotional manipulation" is ridiculous. You want to see what emotional manipulation actually looks like, watch an Apple keynote. This is a guy risking his fortune on a crazy dream and presenting his efforts in a technical and factual manner.

Successful terraforming becomes easy once we can send alot of rockets to a destination? We are emperically terrible at sustainably making our own planet more hospitable to human life, how is Mars easier? I'm actually bewildered here; just baby me and spell out how the Mars colonization process works if the only significant requisite is being able to move things from point A to point B. Do not dodge by saying we've colonized land on Earth.

Remember, the talk was about a method of transportation, not colonization as the title suggested. Optimism is great; don't let it be a means of deception.

You're my hero! This attitude is why I quit regularly contributing to this site. Any time any single person does something positive, some armchair "expert" comes out the woodworks to tell you how it won't work or can't work.

Don't stop contributing if you're one of the good ones!

I want to, but it got to the point where the hivemind has pushed me away. I have noticed recently that HN is becoming self-aware. More than ever, I'm seeing comments by good users telling the bad ones to take their bad attitude elsewhere. The contrarianism going on really drove me away. I started to believe that there were people feeling the need to be contrarian just to appear more intelligent than the other users.

Elon mentioned that there is no physical frontier left to explore on Earth, what about deep water exploration?

If exploration is the goal, wouldn't you get a lot more bang for your buck with a swarm of robots and probes around and on Mars? Sending people is very expensive in contrast.

Venus also has no magnetic field. It has much stronger gravity as well, requiring larger rockets to take off from it, and it is quite difficult to mine resources from due to the high temperatures and pressures at the surface, meaning all materials for a colony would need to be sent from Earth.

Venus has an induced magnetic field which while isn't as good as what we got on Earth, is better than what you have on Mars. https://en.wikipedia.org/wiki/Atmosphere_of_Venus#Induced_ma... Additionally the current theory is that if Venus will be sped up to below 56h per rotation it would regenerate it's intrinsic magnetic field which should be near earth levels. And while Venus does have higher gravity than Mars, it'…

"Additionally the current theory is that if Venus will be sped up to below 56h per rotation it would regenerate it's intrinsic magnetic field which should be near earth levels."

That's great and all, but how exactly do we realistically speed up the rotation of a _planet_?

This Q&A is painful... it's a combination of people shamelessly plugging their own products (Funny or Die you just lost a viewer with that stunt) and people who sound like they may be (literally) mentally unstable.

There are scattered in somewhat normal questions... but not by anyone I would consider qualified to even be asking questions.

Some possible reasons; Mars has a c02 atmosphere, water ice, it has a ~24 hour day as opposed to the moons 28 day-day, Earth and Mars have similar sizes.

Why does the Mars 24.5 hr day versus the Moons 28 day-day matter? What are the consequences of this big difference between Earth day and the moon/Mars day?

14 consecutive days of darkness in the moon creates issues with solar energy, heating, etc.

I'm not sure whether it's a good thing or a bad thing that Elon's presentation ends with requests to throw comics onto the stage and ask him to allow receiving a good luck kiss from a girl in the audience.

To be honest I think it's a really bad fit to have these kind of questions during such an event; but hey, because of them I'm pretty sure this is all really honest and not at all orchestrated... Which is good, I suppose.
