But that mistake is not unique to Falcon 1. There have been payloads lost on the first flights of other launch vehicles. From what I understand, these first flights are often heavily discounted because even the customers know that the odds of success aren't as good as they would be further down the flight schedule. I'd say from that point of view, it's been a successful program. That's the sort of history re-writing that really annoys me. NASA, ULA, Orbital, and Arianespace don't get away with that crap, but we're talking about SpaceX, so they get a free pass, because they're the good guys going after the big evil conglomerates. This is b.s. I've consistently had lower expectations of SpaceX because they're a startup. I'm not rewriting history in any way shape or form. You'd rather complain from the very beginning that SpaceX is a failure because they're not immediately as successful as ULA or Arianespace with their multiple previous generations of launch vehicles to draw upon when designing the next one. Note that Orbital went through *a lot* of initial growing pains and suffered many failures before it was accepted into the "big boy's club" that you refer to. Orbital's launch vehicles were unique in many ways and therefore failed in unique ways. That's to be expected. SpaceX is currently paying its dues and obviously isn't fully accepted into the club yet. But if it keeps making progress and keeps its costs low, it will make it into the club. If SpaceX built and flew its vehicles just like the existing "big boys", then its costs would be just as high and they wouldn't have a chance of selling launches given the current glut of launch vehicles in the same class as Falcon 9. Their business plan is to undercut the costs of the compeition, which requires them do to operate differently. Those differences are largely proprietary, but some can be seen if you look closely enough. It has allowed SpaceX to go from zero flown hardware to hardware which has proven itself from launch to orbit insertion with a vehicle about an order of magnitude smaller (and quite a bit cheaper) than Falcon 9. I'm sure DARPA, NASA, and Celestis are thrilled to learn they were guinea pigs for SpaceX learning how (not) to launch rockets. If they claim they didn't know they were guinea pigs, they're either lying or incompetent. The statistics of first flights of any new launch vehicle are public knowledge. It truly doesn't take a rocket scientist to look at that data and realize that you're taking a gamble on a first flight of any launch vehicle, especially one which is the first launch vehicle for a startup.

But that mistake is not unique to Falcon 1. There have been payloads lost on the first flights of other launch vehicles. That's what I meant about not learning. SpaceX dumped payloads into the ocean ten years after Arianespace sent Cluster into a million pieces on A501, and eight years after Delta III dealt Galaxy X a similar hand, and these were launched by companies with decades of space launch experience. Being the new kids on the block and trying to do things on the cheap is not an excuse to be foolish. A decade after the Cluster fiasco, SpaceX had to learn that error again? What mistakes and lessons ignored will SpaceX present us with Falcon 9? All this to save a few bucks? That's the sort of history re-writing that really annoys me. NASA, ULA, Orbital, and Arianespace don't get away with that crap, but we're talking about SpaceX, so they get a free pass, because they're the good guys going after the big evil conglomerates. This is b.s. I've consistently had lower expectations of SpaceX because they're a startup. I'm not rewriting history in any way shape or form. I was too harsh with that. I apologize. You'd rather complain from the very beginning that SpaceX is a failure because they're not immediately as successful as ULA or Arianespace with their multiple previous generations of launch vehicles to draw upon when designing the next one. I wouldn't have if they had treated their first flights as test flights. They didn't. They carried an expensive satellite on top (just because it was cheap for a satellite doesn't mean it was cheap) and therefore demanded they be judged relative to ULA (well, LockMart and Boeing then) or Arianespace. They don't get to have it both ways just because they're cheaper. Note that Orbital went through *a lot* of initial growing pains and suffered many failures before it was accepted into the "big boy's club" that you refer to. Orbital's launch vehicles were unique in many ways and therefore failed in unique ways. That's to be expected. But after the first Pegasus XL, the first Ariane 5, and the first two Delta IIIs went kablooey, SpaceX felt it right to put our tax dollars and years of hard work by some rather unfortunate guinea pigs on top of the first Falcon 1. And we let them get away with it. And then they did it again. SpaceX is currently paying its dues and obviously isn't fully accepted into the club yet. Possibly because SpaceX hasn't paid its dues and seems to ignore history in the name of saving a few bucks. The NASAs, ULAs and Arianespaces of the world had to go through years of pain, and they were called on the carpet when things didn't work out (remember the criticsim heaped on Space Shuttle, Atlas I, Titan 34D and Titan IV during their myriad and varied failures?) But not SpaceX. SpaceX dumps an expensive satellite in the lagoon when the maiden flight fails, and critics are chided for calling them out on it. Then SpaceX calls Flight 2 a success despite failing in stage 2 and dumping another assortment of payloads in the sea, and that is met with disgustingly little challenge from the fanboys. Now we're being told to shut up and color when we point out that Falcon 9 is an order of magnitude more complicated for a company with a dubious success record to date and maybe, just maybe, we shouldn't be depending on them to keep ISS alive for the next 10 years. But if it keeps making progress and keeps its costs low, it will make it into the club. Which is as it should be. The problem is that we are being asked to admit them into the club YESTERDAY, before they've demonstrated said progress. We're basically betting the ISS farm on them, with very little justification for doing so. Brian |

We're basically betting the ISS farm on them, with very little justification for doing so. We're not betting the farm just yet. Orbital has one of the contracts and they've got a lot of practical experience building and flying satellite busses. Admittedly Orbital's design does not return anything to Earth, so it's very unlikely to evolve into a crewed vehicle. Also, the latest proposal from the Administration brings back Orion as a CEV sort of vehicle for ISS. A crewed capsule isn't an easy thing to do and I don't object to having multiple backup plans (paying or trading for Soyuz, Progress, ATV, and HTV flights are always options too). But what I want out of NASA (or Congress/Senate) is a clear policy (or law) which states that when the commercial providers finally do mature their vehicles that NASA will cease and desist their government designed (Orion) vehicle flights to ISS and let the commercial providers take over that market. One of the biggest challenges for the startups is raising enough money in an environment where they are seen as competing with the government. When the government threatens to step in and wipe out your market at the blink of an eye, it's kind of hard to convince investors that you've got the "right stuff" and will eventually turn a profit and provide a return on their investment.
