Also don't come including barge rockets, because that was strictly R&D. its all about confidence and perception. one $200+ million disaster can be overcome. not two; after both challenger and columbia disasters it was ~2.5 years before another shuttle flew. the next Falcon9 launch is September 20th. stay tuned. Elon Musk is masterful when it comes to PR. https://twitter.com/elonmusk/status/774150065166229504 "Still working on the Falcon fireball investigation. Turning out to be the most difficult and complex failure we have ever had in 14 years" sounds like Elon Musk is preparing the SpaceX fan base for some launch delays. | ||

And that's assuming SpaceX is actually profiting on its launches. It's a private company; we don't know for sure. I have my doubts that it is. | ||

The US government contracts are a luxury for Boeing, and the US Gov does what ti does with Boeing because it wants to leverage the decades of institutional expertise of that company to do things they don't know how to do. SpaceX is a startup that relies on speculative government contracts, doing things that the government itself (NASA) actually has greater expertise in. Then you're not actually concerned about the taxpayer. They have the exact same contract: build a 7-man capsule to launch on their own (or any man-rated) rocket with up to 6 flights. Boeing's contract is worth 60% more but the US government is supposed to have some kind of investment arrangement with SpaceX - because the company is smaller and newer? Just like if you go to a pizza shop and buy place an order for a bunch of pizzas, you become an owner! As though it wouldn't be an issue for NASA to do business with a company they have a literal stake in.  The degree to which SpaceX "relies" on the exact same contracts that other companies get is not relevant when those contracts weren't created to help SpaceX. SpaceX just happened to win them by being the best.

We already have Fermilab, why are we funding a second Fermilab that will keep all its patents, discoveries, etc secret then sell them to us? They're discovering secrets in things that you think NASA does better? Make up your mind. | ||

However, any potential gain goes to them, while all the potential losses are on the taxpayer. Is a classic crony arrangement. | ||

I simply feel that in the aftermath of this accident, more people are willing to pay attention to my criticism than they were before. It's easier to say "I question their quality control capabilities" shortly after an accident than while their recent flights are mostly successful - even when the criticisms themselves are valid. | ||

Is a classic crony arrangement. The gain to the taxpayer is that SpaceX delivers what NASA seeks in their contracts, right? meaning crew and cargo launches to the space station, and that this is cheaper than the Space Shuttle, than Soyuz, than Orion would be, and it's even cheaper than Boeing who you don't also want to force to pay dividends back to NASA. By "potential losses" I assume you mean "what if a rocket blows up again?" and without looking it up, I would really doubt that SpaceX isn't liable for failures. But there's not much to worry about because Dragon already exists and has been flying. Boeing, on the other hand, didn't participate in commercial resupply, and didn't even think they were going to win commercial crew because they hadn't built real hardware yet and were going to abandon CST-100 without the contract. | ||

You chose your words carefully to make it sound like SpaceX made a major breakthrough that no one else has been able to make. In reality they improved on an existing system, or at least apparently did because it hasn't been tested with actual people inside. Much less impressive. Soyuz is an old technology. It has obviously received minor upgrades over the course of 50 years, but it is fundamentally the same craft that works as it did when it was launched. The same tiny 3-person vessel that it was five decades ago, with the same purpose - probably because history has shown that one of the best ways to ensure reliability for space travel is just to figure out how your craft tends to fail and address those errors until it becomes reliable. Not really a catch-all design that suits every purpose; just a bare-bones old design with minor upgrades. The bigger point, however, is that SpaceX has failed to show that as of yet, their technologies are actually useful innovations that justify its existence. They have recovered a rocket, but as of yet failed to show that it can be reused - or, more importantly, that it is actually useful to reuse them. History suggests that maintenance costs plus the costs of designing a craft to actually be reusable are more significant than the savings you get from actually reusing rockets, and SpaceX has yet to show that they have overcome this historical difficulty. Their manned craft have yet to even carry a single person so their capabilities cannot be judged one way or the other - many things change between testing runs and real launches. By default, missions that have actually flown and been successful, regardless of their faults, are better than unproven technology. And until SpaceX proves that it has done something particularly useful, it's merely a redundancy that offers cheap prices (which we don't know if it profits on) and average reliability. So far it's survived mostly on government support (financial and technical) and the Musk hype train, and a number of factors make me question if it will ever manage to be anything more than that. | ||

WASHINGTON — Virgin Galactic’s second SpaceShipTwo suborbital spaceplane made its first flight Sept. 8 as the company takes another step to recover from a fatal 2014 crash. During the “captive carry” test flight, which took off from and landed back at the Mojave Air and Space Port in California, SpaceShipTwo remained attached to its WhiteKnightTwo carrier aircraft. The flight, lasting 3 hours and 43 minutes, tested the airflow around the vehicle and its overall performance at the low temperatures found at altitudes of about 15,000 meters, where SpaceShipTwo would be released on a typical flight. The flight was the first time this SpaceShipTwo, known as VSS Unity, left the ground. Virgin Galactic rolled out the spaceplane in a February ceremony at its Mojave facility, after which the company spent several months carrying out ground tests. While the company called the flight an “exciting milestone” for the company, it disclosed few details about the test flight itself. “With this flight in the books, our team will now analyze a mountain of flight data, learning what worked well and what could be improved for our next flight test,” the company said in a Sept. 8 statement. The statement added that Virgin Galactic may perform additional captive carry tests depending on the outcome of the data analysis, as well as vehicle inspections and other planned work, before moving on to the next phase of the flight test program, where SpaceShipTwo is released from WhiteKnightTwo and glides to a runway landing. The company will later conduct powered test flights, where SpaceShipTwo ignites its hybrid rocket motor in a series of tests of increasing duration. Source | ||
