In 2017? Or ever?
Ok, you've got my curiosity going. Memory says that the Vandeburg launch site was modified to do F9 or FH and at one time the first FH launch would be there.

Even a single million will do the trick though, and this can be done in under 100 years.Not under anything close to a rational economic model, and not with chemical rockets. Never going to happen. Not even close.

Digitize (at least) a few hundred thousand individuals' DNA sequences. Pack them into a spacecraft that also contains all the precursor chemicals to turn the digital data into human beings, as well as enough servos and AI to control the process.
As long as they insist on innovating and upgrading the platform, they're going to find new and exciting ways to blow up, and I don't think they should shy away from that. Customers just have to be aware that they are trading risk for cost. As long as that risk can be quantified (and insured against), I don't think they'll have any issues with future orders.
The real problem will be Commercial Crew.

Other pretty brilliant people are starting from the position that it is possible... they at least have a chance. Reuse is another such example.Reuse is a billion times easier. Heck, it's been done before for over 35 years, and it doesn't require launching tens of thousands of people - and everything they need to support them - at every opposition to a planet with no ability to support their lives.Landing tens of thousands of tons on Mars every two years economically with chemical rockets is just not going to happen.Doing with nuclear rockets is even less likely.

This. If the RTF blew up, that would be really bad for them, but they're enough cheaper than ULA that they don't need ULA-level reliability to be commercially viable.
I don't think most commercial payloads cost enough that paying the difference (for an ULA flight) is worth it for a few percent improvement in reliability (say 93% to 99%). Wasn't the one destroyed "only" $200 million or so? If so, you'd need something like a 20% reliability difference (79% vs 99%) to make up for a (say) $40 million cost difference.The real problem will be Commercial Crew.
It's less likely because it's damn sight more difficult to do than building the ITS. Someone who knows (Henry Spencer) is of the opinion that inner planets exploration is best done with chemical, you only need nuclear for the outer planets, which is much longer term goal anyway.And note, NO ONE is developing nuclear engines, and the cost to do so would dwarf the cost of the ITS system anyway.

Not quite "dwarfing" cost of ITS (which is more likely more than the $10B Musk is speculating on.The NR-1 (RIFT) program was a close to flight prototype; proposed designs are more sophisticated and advanced. One way to pay for the cost is in avoiding multiple SLS launches needed for chemical alternatives. NASA still spends money on testing core materials as the concept of NRP has never really gone away. see: https://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/20140002718.pdf and spirit.as.utexas.edu/~fiso/telecon10-12/Borowski_6-27-12/Borowski_6-27-12.ppt
I recognise that comsats are less exciting than Mars, uh, occupation. But there is no business case for occupation. Without profit it cannot scale.Comsats have been shown to be profitable. A LEO last-mile constellation addresses a growing trillion-dollar market, but has, so far, cost too much to deploy.If SpaceX can drop the cost of a LEO constellation enough to make last-mile internet service cost effective, that will change them and the world utterly. Apple is a nearly $200B/year company. SpaceX can be a > $500B/year company. The available profit will force them to hire hundreds of thousands of people. They will end up in very high stakes negotiations with most countries. The real estate of space will become vastly more valuable, and therefore there will be more struggle to control it, both commercially and militarily. Huge numbers of people who currently do not care at all about space stuff because it does not affect them will become interested.Therefore, the most important thing SpaceX can do in 2017 is make progress on the constellation. Launch a couple demo satellites.

As always it depends. Can SX develop the system for a low enough price that they can recoup the costs on the passenger? $500k for a 100 passengers. That's $50m. Full reusability means the more flights the more profit if the operating costs are a (fairly) small fraction of total customer revenue.

Quote Huge numbers of people who currently do not care at all about space stuff because it does not affect them will become interested.Huge number of people depend on the GPS system but how many of them think about it's satellite based? There's a rather amusing Sky news report where one of their reporters is interviewing someone from Reaction Engines. The reporter is literally unaware that what they do depends on comm sats working. Unless the service is directly delivered to them by "SpacexBroadand (TM)" I doubt anyone will notice it. The money it generates is another matter. If the revenue produced is that great all of SX's goals become easier. QuoteTherefore, the most important thing SpaceX can do in 2017 is make progress on the constellation. Launch a couple demo satellites.Certainly on their todo list.

So, even if the rockets are free, the operations costs are free, the supplies and equipment are free, and you have 100% reusability, it'll cost more than that.
