Elon Musk’s Updated Mars Plans

Why BFR will Replace Falcon 9

To many it seems illogical why a huge rocket like the BFR will replace the Falcon 9. I’ve seen arguments that most launches don’t need huge payload capacity.

The internals of the BFR spaceship (so excluding the booster). 48 meters long and 9 meters in diameter.
The Electron rocket is just 17 meters long in total and 1.2 meters in diameter.

No We are Not Abandoning Earth

A common opinion among many commenters on Musk’s plans is that he is somehow trying to run away from the problems on Earth. He has repeatedly stated that is not what this is about. When Elon Musk talks about not keeping all the eggs in one basket and saving the human species, he is not referring to our current global climate change. In fact he is doing his best to combat this with Tesla and Solar City, to replace our fossil infrastructure.

How is Fuel Production on Mars Possible?

I’ve seen people skeptical of the ability to produce fuel on Mars. In fact this idea is not new, but initially proposed by Robert Zubrin in his Mars Direct plan. Some seem to think this involves building some large factory on Mars, and think it would be much simpler to simply send an extra fuel tanker to Mars.

CO₂ + 4H₂ → CH₄ + 2H₂O

How Will This Change The Space Industry?

While many of the effects are hard to predict, the dramatic decrease in launch costs a reusable BFR will cause, will dramatically change the way we thing about the space industry and how it operates. So much of how we do things today is a result of extremely expensive launch costs.

Just a single asteroid 500 meters across could contain more platinum than has ever been mined on earth in total.
