SpaceX Falcon 9 Blasts Off From California 97

An anonymous reader writes "SpaceX's Falcon 9 rocket completed a successful first launch today, taking off from California and putting a Canadian science satellite in orbit. 'The beefed-up Falcon 9 that blasted off on its maiden flight from Southern California's Vandenberg Air Force Base, carrying a small Canadian government communication and research satellite, went through a seemingly picture-perfect countdown and performed on ascent as engineers hoped. The changes to the rocket are aimed at improving capacity and reliability, while simultaneously speeding up manufacturing. Historically, the initial launch of a new rocket has as much as a one-in-two chance of failure. Early this month, Elon Musk, the company's founder, chief executive and chief designer, seemingly tried to play down expectations by sending out a Twitter message emphasizing that the revamped rocket 'has a lot of new technology, so the probability of failure is significant.''"

        New technology, new problems. Greater complexity, greater complex problems. All of that better technology also requires better talent which is also harder to find. Sure, they undoubtedly probably solved many of the old problems, but they've all been replaced them all with new ones because "problems" never go away. Just look at our modern world, do we have fewer problems than we did a century ago? hah...

      The MO of SpaceX is to under promise and over deliver. But adding new technology on top of more new technology increases the probability of failure rather than decreasing it, until that technology has been tested and the bugs are ironed out. Today's launch was one of those tests. They were testing new technology that will let them relight the first stage after separation and bring it back for a controlled landing. That new technology adds additional complexity that had a nonzero chance of making the rest of the rocket fail due to untested redesigns.

        Eh, I say this as an enthusiastic supporter, but they've been quite short on their predicted launch frequency. That's a critical part of their business model.
        • Next year is going to be the year for SpaceX to put up or shut up. Their manifest is absolutely huge, and Elon Musk made some rather bold predictions at the after-launch press conference today. He made the bold claim that he will actually launch a used Falcon 9 1st stage by the end of next year. I'd like to see him try.... seriously!

          The video tour of the SpaceX plant in California (given just before the launch on the webcast) showed the plant being extremely busy and practically at capacity with a half dozen Dragon capsules already under construction, a whole row of completed Merline 1D engines, and a whole bunch of rockets all lined up at various stages of completion. Whatever problems SpaceX has with their rockets right now, it isn't a supply problem at the moment. All of that hardware certainly costs a whole bunch of money, so they've definitely dumped some serious cash on trying to meet that huge manifest.

            Part of the problem is that (as far as I can tell) they've switched completely to the new v1.1 for mass production. (I guess the v1.0 just wasn't designed for mass production.) Today's launch is important because now this new version of the rocket has had a successful launch, and that opens up a lot of future launches. In particular, there is one launch of a communications satellite in the next couple of months that was contingent on having a successful launch first.

    • Rocketry is something that is sitting on such a fine line between success and failure that just a tiny mistake that would be ignored in most other human endeavors is likely to destroy the vehicle when trying to put something into orbit. For example, the first Falcon 1 rocket simply disintegrated because a simple three cent nut was made out of the wrong kind of metal and fell off at a most inappropriate moment. The salty air + moisture from sitting just a few hundred feet from the Pacific Ocean at the time didn't help either.

      Another problem is that to improve technology, you need to experiment and try new things. Far more often experiments tend to be failures rather than success as you try these new ideas... hence if you are using new technology, especially for the first time like SpaceX was doing today, the likelihood of failure would actually increase and not decrease. Only when it has been used many times and has been "proven" can you even remotely say that the likelihood of failure would drop.

      And no, in spite of nearly a century of rocketry and nearly a trillion dollars spent by everybody involved, we still are just beginning to understand the technology and what it can do. There still are some amazing ideas that have yet to be tried.

      • Insightful comments, thank you.

        Rocketry is actually the true "intelligent design", pitting human minds and ingenuity against the constrains of the physical world, including space.

        It's unfortunate that there isn't more payoff for commercial efforts, I wouldn't mind quite a bit more space effort. I'd love for near Earth orbit to be our backyard, with a "cruise ship" there. But pure economy and rocketry make it a difficult proposition. Imagine the ship from The Fifth Element...

    Historically, the initial launch of a new rocket has as much as a one-in-two chance of failure.

    Historically, new rockets have been of an untested design, without much in the way of previously-tested designs to use as a reference. The SpaceX Falcon 9 is built largely around previously-tested designs, on top of solid engineering. One would suppose this would give it a better than 50/50 chance of success. In fact, the space shuttle program, viewed over its total life, had something like 93% success rate for its engines. Much of the SpaceX projects' development is based on the results of those tests, designs, and engineering expertise.

    It would be highly suspect of their rockets had a failure rate much higher than that -- one would expect a higher success rate due to incremental improvement, not worse.

      The Falcon 1 rocket had two successful launches out of five attempts. Still, in the case of this particular version of the Falcon 9, so much had been changed that it was essentially a whole new rocket.

      Typically most aerospace engineers try to do incremental changes rather than having so many like is being done here today. If anything, the historical trend is to use very old designs and just do very minor tweaks a little at a time. Examples including the Atlas rocket, which first flew in December 1957 and is still flying today (with admittedly a bunch of revisions over the years that make the current rocket bear almost no resemblance to the original rocket). The same could be said about the Soyuz spacecraft, which also has had numerous revisions over the years but rarely very many changes on any particular flight. Most of even the American rockets are using very old Russian engines (like the RD-180 [wikipedia.org]) instead of newer engine designs.

      It is far more unusual for a new clean-sheet design, especially a brand new engine design like SpaceX did with the Merlin engine. Most of the time when new designs like this are made, it is mostly an academic exercise and the rocket almost never actually flies. Frequently companies who come up with new designs simply go bankrupt before the hardware leaves the ground, assuming that any sort of hardware testing was ever done in the first place. In other words, for actual flying hardware, it is mostly very well tested and very old designs with at best very minor tweaks.

      This particular flight is especially unique not just because of the larger rocket, but most especially the new Merlin 1-D engine where this was the first time that particular engine design had ever been used. From a study done by the Aerospace Corporation around the year 2000, there were several critical areas where rockets would most likely fail, and the #1 cause was a failure with the engine design itself. As a matter of fact, even with this particular flight that was no exception as the Merlin 1-D engine on the 2nd stage apparently did fail. Luckily for SpaceX, if failed after all of the payloads had been deployed so it won't impact their bottom line.... but there was a spectacular test they were going to do (it was rumored they were going to try to fly the raw 2nd stage past the Moon with the remaining propellant). Instead, this stage is going to crash into the Earth eventually as just another piece of random space junk.

      There were also new avionics that had never been used before, a new faring design (also a common failure point for many rockets), and a brand new launch site that had never been done along with an orbital profile that this particular rocket had never been proven with doing either. The only other rocket that I'm aware of that did this many firsts all at once was the Saturn V, and that was done simply because the NASA officials involved didn't want to waste several launches proving new technologies and decided to do everything at once. The "space race" was also a major factor with the Saturn V as NASA was under some extreme time pressure to perform and get people to the Moon.

      • Typically most aerospace engineers try to do incremental changes rather than having so many like is being done here today.

        Perhaps as an integrated system. But each component here has been previously tested in other designs. The big problems so far seem to have been software and integration issues. There was a non-fatal flaw in excessive vibration which caused a premature engine shut down, but these are all pretty normal from a systems integration perspective. The project has seen far fewer setbacks overall than what historically should be happening if it was a true clean sheet design.

          Yeah, it isn't something from the 1960's. That still is a design that is over 20 years old, being designed at the same time most PC computers were running with 8088 chips as the primary CPU and the primary operating system was MS-DOS. Well, perhaps slightly better computers were around, but not much better.

    Here's a much better link: SpaceX successfully launches debut Falcon 9 v1.1.

    Then, this F9 "v1.1" was much more of a version 2.0. It had its engines uprated from 95,000 lbf (sea level) to 140,000 lbf (sea level). They also are arranged in different way (from a 3x3 grid to a circle of 8 with one engine in the center) which meant a new thrust structure. It also has its fuel tanks stretched by 60% making it much heavier. This is as far as you can go from the 1.0 and still keep the name. Succeeding with this in the first try is good.

    There's no news though on them recovering the first stage. It was meant to brake and reenter intact and try for a "landing" on water. Or maybe they just want to tow it home first (but its hard to imagine Musk not bragging about it).

      The basics of the first stage recovery were that it re-lit fine for re-entry, and re-lit for the deceleration burn, but developed a spin that exceeded the ability of the attitude control thrusters to counter, causing the fuel to be flung against the walls of the tank, starving the engine. It broke up on impact. SpaceX believes that the data gathered will be sufficient to solve the puzzle.
