The helium is used to pressures the fuel system, so it has quite a lot to do with the engines, even if that was not directly the part that failed.
He isn't wasting anything if NASA is getting what they are paying for. What he does with the profit is 100% up to him.
I don't think anyone is expecting any of this to be done 'with ease', but SpaceX pretty much has already leapfrogged all those other entities in cost effectiveness. I guess time will tell if they are doing this at a detriment to safety and reliability, but so far they have a better track record than older and more established competitors like Orbital.
I've got my own criticisms of this plan, as I think it focuses a bit too much on scale, leading to a more difficult mission architecture that substantially complicates things, though at least this plan doesn't require some kind of nonsensical orbital construction technology we aren't even close to achieving yet, which is more than we can say for NASA's plans.
new Wait But Why blog on the subject. It's a great read

All liquid fueled rockets need some way to pressurize the fuel system, so this doesn't sound like anything to do with the engine. Even if it did, the other rockets also have new engines, so the newness of the Merlin engines can't be an excuse.
I think that depends a lot on how he's achieving those profits. Something I've read about SpaceX recently that's pretty troubling is how few people are actually being used full time for crewed spaceflight missions that NASA is funding: "Another contributing factor to SpaceX’s commercial crew launch date slippages is that it has only a few, perhaps little more than two or three dozen, SpaceX employees working full-time on commercial crew; most of the others are multi-tasked to Cargo Resupply, Red Dragon, and commercial satellite services."

So it sounds like he's multi-tasking NASA's missions with all of his others he's pursuing, leaving only a very small team dedicated full-time to accomplish what NASA is paying for. I guess you have to ask yourself if this is a valid way of fulfilling that contract.
He has not leapfrogged that many competitors in cost. Proton, Soyuz are arguably still more cost effective rockets. There's also a number of small-sat launchers that are much cheaper as well (Vega, PSLV, etc.). It's only really ULA, which was a monopoly on government launches until recently, that charged exorbitant prices. He deserves credit for breaking ULA's monopoly, but that doesn't means he's qualified to send people to Mars.
Agreed for the most part. I will add that the ITS rocket is the N1 on steroids, and has no dedicated launch escape system. Just because NASA doesn't have a well thought out plan to Mars, doesn't automatically mean SpaceX has a better one. If anything, SpaceX's plan is worse IMO.
I wish we had already done this and are even more prepared to go to Mars nowI kinda wish that we would go to the moon first, this mars-mania is all fine but i'd rather see us deploy an outpost on the moon first for scientific research and what not, it would be safer, we would already have water there if we chose a spot correctly. Plus going to mars we'd have to wait 1½ years till the orbits would match while we could get to moon and back whenever we want.
So i'm in the camp of colonizing moon first, we aren't terraforming mars anytime soon anyway.

The fuel pressurization system doesn't need to be a hard cryogen like helium though, or anything that is likely to cause a catastrophic failure in the event of a leak.
I don't know about the Proton and the Soyuz, but I know the Falcon 9 is substantially cheaper than the equivalent Chinese Long March last I heard. I wouldn't have thought that the Russians would be cheaper than the Chinese, least not for anybody but NASA.
Just because the ITS uses many rocket engines doesn't make it anything like the N1. We have advances substantially past 1960s Soviet computer technology, it should be feasible to devise a better control system for a many-engined launch vehicle these days. Launch escape systems were going to have to go away eventually, and it becomes a bit impractical when dealing with spacecraft this large. Lack of a launch escape system didn't hurt the space shuttle, and the shuttle tragedies would not have been avoided by a launch escape system.
It makes sense to have such a system when you are dealing with Apollo and Soyuz size vehicles, but for any realistic Mars vehicle(even a barebones Mars Direct style 2 or 3 man crewed vehicle) it seems like it would be impractical.
I guess since this vehicle requires in space refueling, if you were being silly you could shuttle the crew up in small capsules and rendezvous with the ITS during refueling, seems horrendously inefficient, at that point you may as well turn the ITS into a Mars cycler and just keep it up in space. Problem is there is currently no way to create artificial gravity in the mission architecture.
Or we could just make the thing safe enough to not need the thing in the first place, which if you are going to try to get a million people to go to Mars, you are going to have to do that anyway.
Yeah, people can argue that it is impossible until they are blue in the face. Meanwhile SpaceX moves forwards. Unless something is physically impossible, what is the argument really? SpaceX will do anything in their power to try and reach their goals.To all of those shitting on the presentation, I wish you were around on NASASpaceflight.com back when Elon announced that they were going to try and work on reusability for their rockets. It was shat on to SUCH a large degree in many of the same ways (it's nice to dream Elon, the re-entry forces on the first stage are going to tear it to pieces, the landing legs will take up too much space and they'll weigh too much, SpaceX can't afford a testing regime like this, landing on a barge is impossible!) and to a certain extent, still is. And yet here we are, 5 years later with SpaceX sitting on 6 landed first stages.
Yes, it is pretty exciting. Dr. Robert Zubrin also said some things related to this subject in a video posted earlier. He suggests that NASA needs to please the people in charge of funding with their mission plans in order to get proper funding, and that this often causes the plans to be bloated with unnecessary steps and development of unnecessary hardware. Also they could be forced to change their mission at any time. A private company can be more focused and certainly more lean.It's amazing to me that we are living in a day and age where two multibillionaires (Musk and Bezos) both own private rocket companies that are currently working on HLV and SHLV SPECIFICALLY designed to make life multiplanitary. Blue Origin's New Armstrong rocket was briefly discussed at the IAC yesterday as well and they mentioned that it is also being designed to go to the moon and Mars. The redundancy of the two companies, wholly outside the complete control of Congressional funding, makes the likelihood of success that much greater.
While pre-launch accidents are indeed rare, your claim it's a solved engineering problem is invalid.In the US it's the first in 50 years.
the shuttle tragedies would not have been avoided by a launch escape system.
God musk is so bad at speaking. Somebody get him some Adderall.

I'd probably decline because I know there's no way in hell my wife would go and it's a one way trip. Were I unattached I'd be tempted though, its a unique opportunity
It's not a 1 way trip though!
I doubt they'd send a random Sysadmin a scientific mission, and the only way I could afford the pricetag is by selling my house, so it would be a "move to mars" type deal for me!
Yes. I totally would. Given I pass the phsucj exams that totally would be necessary.So you're offered a spot on this spaceship. Who says no?
If I'm single/unattached and have the cash when the time comes, I'd probably go.So you're offered a spot on this spaceship. Who says no?

I have kids now so that's a no. If I didn't, who knows. Probably still no. I reckon the first waves will probably (80% chance) meet their demise, so you really have to have a this life's pointless anyway better make my mark mindset.So you're offered a spot on this spaceship. Who says no?
Can't wait until Mars is the first Technocratic country started by corporations, where people vote on which Google AI iteration they want to be president, the main difference being that the conservative AI will give you 978 energon credits, and the liberal will give you 977 energon credits, the extra credit going towards increased Tetrahydrocannabinol and Doritos(TM) rationing. Oh, also each AI will reside inside of a zord.

Ehh, I seriously doubt that first flights have 80% chance to die. I'm sure that they will send multiple unmanned flights just to send cargo and test all systems before the manned flight
What makes you say someone would have to live there for years or the rest of their life? Is it because you're simply spectacularly uninformed or do you some valid explanation?While true, I'm not sure it would be fun. You'd get over the spectacle and awe and achievement fairly quickly, and all you'd have left would be living in a cramped shed in a barren wasteland for years, if not the rest of your life.

Lol, seriously.
Falcon Heavy was supposed to debut in 2013, and now it is tentatively scheduled for Q1 2017. That's the thing about SpaceX though. Nothing is vaporware. Instead, it is constantly being iterated on and further developed. Since 2013, they've rolled out the full thrust F9 with deep cryo lox and have refined the landing of the first stage like crazy. I expect something similar with the ITS. It'll be late and it probably will evolve from this video, but it'll materialize and be even more amazing than we've initially seen.
