There has never been a science fiction movie or TV show explaining the one overwhelming obstacle we face today to a spacefaring future: The impractical economics of having to build an entirely new rocket for every single flight.  And basically the aerospace industry is happy to leave that minor technical detail generally unknown, because the way the government contracts rocket flights, their absolute profit actually increases the more expensive their rocket flights are - so for decades Big Aerospace and the big institutional purchasers of space launches (primarily the Air Force and intelligence agencies) have been in a perverse, corrupt arms race to deliver minimum value at maximum cost to taxpayers.  SpaceX has spent the last decade challenging both, and rather successfully - which is why its CEO (and also the guy behind Tesla Motors) Elon Musk doesn't have a lot of friends in politics compared to his competitors.  

Watch the video below: It's not a simulation.  It's a rocket the height of a high-rise apartment building, and they've flown it six times in a year to increasing altitudes without (as far as I know) a single dime of direct public funding, a guarantee of return by any institution, or even revenue-generating operations as of yet - it's simply Elon Musk and SpaceX's far-sighted investment in overcoming the reason we're not already all zooming around in space, and it's working:

I've blogged about previous, humbler flights of the Grasshopper, so if you aren't familiar with the subject, you can get caught up here with other videos and photos:

Woo-hoo!  Awesome SpaceX Grasshopper Hover-Slam Launch Doubles Previous Height (w/Video)

It's basically a one-tank, one-engine version of the first stage of the commercial rocket they currently fly to space - simplified so that they can tweak and evolve things for ever better economics, manufacturability, and reliability.  And what they've already learned hasn't gone to waste: They've been testing some of the resulting new technologies on full-up nine-engine test stands lately, disturbing the peace for miles around with some of the most powerful rocket engines ever built:

They've been having a lot of healthy failure in the testing process too, burning through components and causing all sorts of aborts, but that's the beauty of an organization with tons of money, zero investor pressure (because Elon Musk has tight ownership and control), and absolute zero-sum commitment to achieving a spacefaring future for humanity: Failures on the ground can only be good - they just fix it until it works before the ultimate flight.  What they're specifically preparing for is a flight currently scheduled for September where they fly the Falcon 9 v. 1.1, which is a much more powerful, efficient, and upgraded version of their current spaceflight hardware, and will also be used to do some initial flight testing of reusable components on the first stage.  Specifically, they're going to try to reignite it after stage separation so that it hits the water more softly, allowing them to recover it.

The goal isn't to recover intact stages from the water and reuse them, but to perfect the process of relighting after stage separation so that ultimately they can stick extendable landing legs on the thing and just land it right back on the launch pad.  Here is a first-stage telescoping landing leg undergoing initial development:

Falcon 9 R Landing Leg

A number of additional milestones will be undertaken by the September flight in addition to the first flight of the 1.1:

1.  Inauguration of the SpaceX launch facilities at Vandenberg Air Force Base in California.  The website for Vandenberg says the launch range is closed to the public, so unless you can get press credentials you wouldn't be able to see the launch up close, but you might be able to see something from a distance.

2.  First flight of a SpaceX payload fairing.  Up until now all of their launches have been to deliver the Dragon space capsule along with piggyback payloads, but the upcoming flight would be the first purely commercial satellite launch for SpaceX, and thus the first use of the fairing - a kind of shell that splits in half in space to expose the payload.  Dragon flights have a different type of shell: The Dragon slips out backwards and launches off to the side.  This is the new satellite fairing during a test:

You can see the engineering involved in the test based on the cables attached to the fairing halves at strategic points, simulating the weightless environment.  They actually had a problem with the setup when they found out it wasn't adequately simulating what it was supposed to, but that was only a temporary hiccup that they were able to fix relatively simply, according to reports.

3.  As mentioned, the first-stage relight test after stage separation.  They've said they expect that test to fail and not be able to recover anything the first time around, so it's mostly a "let's try it and see what happens" sort of thing.  Isn't it refreshing to have a large organization with an attitude like that?

At some point after the 1.1 launch, either late this year or early next (probably the latter), they intend to strap three 1.1 first stages together and inaugurate the Falcon Heavy: Which is designed to be the third most powerful rocket in history after Saturn V and Energia - the Soviet rocket that was supposed to launch their copy of the Space Shuttle, and only flew twice.  Falcon Heavy is, if sporadic reports are to be understood, to be the launch vehicle for what SpaceX refers to as MCT: The Mars Colonial Transport.  I'm not joking.  They're not being cute with that.  It's called the Mars Colonial Transport, its purpose is what it sounds like, and they've said they intend to build it.  There are a lot of steps between here and there, but damn.

Another expected milestone this year is the unveiling of Dragon 2, which SpaceX has said would look radically different from the current Dragon, have its own landing rockets, and be designed almost from scratch because they were being conservative with the original Dragon by hewing closely to 1960s heritage technology and strategies.  Dragon 2 would be the crewed version of Dragon competing for astronaut transport contracts to the International Space Station, and would also be used for independent commercial flights both crewed and uncrewed.  They still have to do pad abort tests and launch abort tests before they have a first launch, but they've already completed some initial review milestones toward designing their testing program toward a target launch in 2015.

The managers of the European Ariane rocket have been concerned about the commercial impact of the rise of SpaceX on their business, and they've initiated planning changes that - for a bureaucracy of their size and international scope - is something akin to desperate scrambling.  This is a major change of pace given that the only other major US rocket launch company, United Launch Alliance, has no business whatsoever from overseas and is basically sustained entirely by monopoly contracts from the US government.  It's been fun watching the dinosaurs slowly realize that there's an asteroid approaching and its name is SpaceX.  It'll only get more fun as time goes on.

If you're not excited about this, consult a thyroid specialist immediately - it may be a symptom of a more serious condition.

8:42 PM PT: I've probably shown this before, but this is the 9-engine test stand seen in two of the above videos, either just as the engines are being ignited or just as they're cutting off:

Falcon 9-R Test Stand

Mon Jul 08, 2013 at 2:21 AM PT: The inaugural 1.1 flight and opening of the Vandenberg launch site is scheduled for September 5th, and reportedly they've already completed the core technology development and are now flight-qualifying the specific stages they've built for the launch.  Since it's such a drastic versioning, and the launch site itself is a brand new facility they just built at Vandenberg AFB, delays have already occurred (it was originally supposed to have launched last month) and are very likely to occur again - but it's more than worth the wait.

Mon Jul 08, 2013 at 3:25 AM PT: The thing about SpaceX that makes it so promising beyond what it's already done and in the process of doing is that its work force is so young.  You just don't see that if you look at NASA mission control, or Lockheed-Martin, Boeing, etc.  You don't even see it so much at the entrepreneurial space companies, because they mostly poached from NASA.  SpaceX, however, stole its talent from Silicon Valley.

        to be fair, the last actual development that NASA did on launch vehicles was the shuttle and it's associated technologies, all from the 1970s. They just didn't have the computer technology for the kind of hardware and software that runs the Grasshopper, nor could they have had it. That was the result of the subsequent four decades of computer development.

        Don't get me wrong; I agree that NASA got diverted from their 60s and 70s dynamism and has lost the innovative edge in things like launch vehicles (though not in other areas, like exploration vehicles, where they've been doing some fantastic work, especially the folks at JPL) but we need to be fair about the things that they could have done and the things that couldn't be done until other technologies developed to a sufficiently sophisticated level.

    ...Hexacopter?  Like little 4-blade r/c "drone"?
    I wondered what deranged lunatic would pilot a helicopter somewhere near that rocket....

    I'm amazed that they can land that thing vertically.  All sorts of questions immediately come to mind.

    The whole vehicle seems to me to have no inherent stability, therefore it must have a very sensitive device that measures the attitude and location of the vehicle very, very accurately, combined with a controlling device that first interprets the data coming from the sensing device, determines which control inputs are needed to respond to the vehicle's motions, and does so in an incredibly short period of time.

    I presume that the "window" the vehicle needs to stay within, in order to remain within the control authority of the attitude rockets, is quite narrow, and the amount of time available to interpret what's going on, decide what to do about it, then execute a response, is also quite small.  

    It's easy in our "modern" world to look at this, shrug, and go "Big deal, man it's a rocket, they launch 'em alla time"...That would be ignorant and foolish.  This whole this is an order of magnitude of increase in difficulty. Watch a few YouTube vids of German guys destroying V-2's one after another and you begin to realize how hard it is to control these things AT ALL, much less making them hover like a helicopter!

    Another issue that concerns me is the control of the exhaust plume from the rocket.  A look at the Shuttle launch pads reveals a very elaborate system to keep the SSME's and strap-on boosters from wrecking the base of the launch pads and harming the Shuttle itself from below as it launches, I wonder how Musk's Rocket Nerds dealt with that part of the problem...My first thought is that it's related to the fact that makes this whole thing possible, that the nearly-empty booster takes a heckuva lot less thrust to be levitated than the thrust required to lift the payload and the original fuel load....Still....

      later in the video, so it's definitely some sort of drone copter.  Don't know if the "hexa" refers to the number of blades or if there are six separate rotors suspending the camera.

      Actually rockets are more stable than people think as long as they aren't too skinny or too small.  Moment of inertia delays responses the bigger a rocket is.  Also, it may seem unstable because it seems to be "resting" on its plume, but actually that's called the pendulum rocket fallacy.  A rocket is no more and no less stable "standing" on its exhaust than if it were "hanging" from several angled rockets at the top.

      Still, it is a huge achievement because this is way more stable than other rockets have been.  SpaceX is an amazing software and component company apart from being a rocket company.

      I had similar thoughts about controlling the plume.  I notice a lot of smoke rising up along the sides of the fuel tank.  I think the key lies in the shape if the exhaust - you'll notice that it kind of splays outward rather than coming to a point like you normally see.  That must be deliberate.

          subtleties like vibration control, aerodynamic pressure (it was at the same time as early supersonics research), etc.  Little differences in air pressure on one side of a rocket would create a net torque and turn it in mid-air.  Or the fuel would slosh around in the tanks and create a torque.  

          I can't even imagine how resistant to frustration someone would have to be to be a rocket engineer.  It seems like it would be the same as being a computer programmer if the laws of physics were your operating system and bugs manifested as catastrophic explosions.

          Those were the steering vane failures, which took a lot of rockets to get right.

          The vanes were small airfoil shaped rudders directly in the exhaust stream from the nozzle, and their movements were what "steered" the rocket on its trajectory. I believe Von Braun and company had to come up with a feedback mechanism that didn't over do the controlling/correcting movements.

          And yeah, I know tarantulas don't really act like that at all, so no snarking, this is the internet damnit!

            controlled vanes. The vanes were extensions of the four tail fins. They were hard pressed graphite, which would withstand the heat and pressures in the rocket exhaust long enough to get the thing up to speed and trajectory.  If any of the electromechanical parts was having a bad day, the thing would wander off course. However, our own early experiences with rocket testing did not fare much better.

          This should have been happening in the '80s instead of the Shuttle, but a late start is still a start, and they're moving a lot faster dollar-for-dollar than Apollo.  It was a miracle, but a miracle built on unlimited political commitment that undermined future progress as soon as that commitment became finite.  It's like that guy who had the cool car and all the girls in high school, and now works at the bowling alley because he couldn't imagine anything beyond his life as a teenager.  

          But I think SpaceX is a new beginning, not an epilogue indictment - they're training hundreds of top-shelf people who each may have the potential to push this paradigm even further than what they're doing right now.  And there's no way to know except after the fact whether one or several of them will exceed their teacher.  That's what's shattering about this company - they're future-oriented.  They know what went before and they don't care.  There's no trace of cargo cultism in what they're doing like there is in so many of the other entrepreneurial space companies.  They'll take or leave the past as they find convenient, always prodding for ways forward from the present state of knowledge and technology.

      Recommended by:
      Troubadour, semiot, polecat

      The engine can't actually throttle its thrust low enough to let a nearly-empty Grasshopper hover, in the video it's carrying many, many tons of ballast to bring the thrust-to-weight ratio close enough to one to let it do that.

      The final product has to land with a much higher T/W ratio, which means a long free-fall with some thruster steering, and then right before it hits the ground it does maybe a 7-8 second burn to slow down almost to zero just as the legs touch the ground.  It's not going to hover or descend slowly like this, it's just going to be speck-WHOOSH-ground.

      So although the test legs in the video are practically on fire about 45 seconds in, it's not a problem because in actual flight conditions the legs are only going to have a few seconds of exposure to the plume.

      As for the Shuttle, one SRB is about 20 times the thrust of that Grasshopper engine, so it's a different league. And secondly, solid rockets have a lot of crap in their exhaust, like hypersonic droplets of molten aluminum. Even at equivalent thrust liquid engine exhaust isn't as harsh.

      It lost its original DoD backing almost certainly because of the (still largely symbolic) threat it presented to the mother lode of contracts, the Air Force bulk-buys of launches.  Any hint that alternatives even existed wasn't to be tolerated - they don't even really tolerate it now with SpaceX physically demonstrating their superiority.  They're having to launch medieval sieges of the procurement office to get a small percentage of future launch contracts while offering a fraction of the price.

    To land in tight spaces, instead of needing a runway. All that fuel it needs to carry to re-entry and land replaces a lot of payload - I still think the 'parasitic' system (like the Rutan design) is more sensible and efficient. This is definitely cool to look at, but seems inefficient.

      is that even though you cut the payload by a certain fraction, you also cut the cost by a factor of a hundred while increasing safety and reliablility by an even larger margin.  And even the decline in payload is only circumstantial because you can just build bigger rockets and still sustain them economically due to much greater demand at the lower price.

      Recommended by:
      Troubadour

      might be very small compared to its weight with a full load of propellant and a payload.

      The "burn" required to land the nearly-empty first-stage might be very small compared to the launch firings....

      I wonder how much residual fuel is in the current booster when it finishes its launch burn-I'd bet it's a surprising amount, I bet they don't let the booster run til it flames out, I bet that they calculate how much speed change they need to perform the mission and intentionally shut it down after a specific number of seconds rather than let it herky-jerk to completely empty...

      I've wondered if they couldn't figger out a way to soft-land the engines alone, since they are the complicated part, maybe some sort of explosive-bolt affair that separates the engine package from the fuel tanks and deploys a parachute....

        to keep more fuel at stage separation for the 1.1.  The cost/benefit is off the charts if they succeed, so there's no reason not to let go of a few million per flight for the possibility of cutting the ultimate cost of orbital spaceflight to 1% of where it is.

      that bothers to protect itself from China.  They don't even patent most of what they develop, because China just uses patents as instruction manuals.  Musk had a great quote, to the effect that the where the primary competition is national governments, "the enforceability of patents is questionable."  The Chinese will just have to steal the blueprints the old fashioned way.

        •  As long as SpaceX never stands still (0+ / 0-)

          they're in no danger of being overtaken by institutional space programs, even if they were thoroughly infiltrated.  We forget how insanely bureaucratic China is, and how much inertia is involved in its programs.  It's mostly, I think, to just avoid giving the Chinese government any sort of start because they tend to pursue things forever once they get going - which is actually a good thing for the species as a whole (since it means they're committed to space), but problematic given our own society's short-term thinking.  

          Still, I don't think they'll even be institutionally aware of SpaceX until it topples ULA and Arianespace, and the moment they started to change course to deal with SpaceX, their actions would be seen miles away and years ahead.  There'd be all sorts of grinding bureaucratic gears resisting or failing to properly implement the necessary changes.  Meanwhile, SpaceX could respond with agility.  Not much short of China doing its own version of the Apollo crash program would really challenge that as long as the company keeps moving forward at its own pace.  It'll only start to wind down when Musk takes it public (no announced plans to do so anytime soon, fortunately) and has to start appeasing investors with shorter and shorter-term results.

    This is rather encouraging. One big advantage SpaceX has is that they do so much in house. If there's a problem with something, the people responsible are right on hand to deal with it.

    NASA's approach of multiple contractors over multiple states back when they were really in the space business may have made sense politically (got to get enough votes in Congress to have any kind of budget), but it was an engineering nightmare.

    ...back in the 90's. But the Clinton Administration apparently thought it would "save too much money" (That quote is snark on my part) and went with Lockheed's X-33 instead, which didn't stand much of a chance and I always hated it because of the required infrastructure. I know they were supposedly trying to, "Push the limits," but apparently Al Gore never got the K.I.S.S. memo.

    The only plus I ever found in the X-33 was the linear Aerospike engine. Now, put a standard Aerospike engine in one of these Grasshoppers and now you're talking!

    I'm glad to see private contractors using great ideas that were thrown away in the corporate world. At least the USAF is finally working on a return/reusable flying booster.

    WTG SpaceX, at least someone isn't relying solely on everything that was already done fifty years ago. Also, thanks to SpaceX for remembering that development means building it and flying it, not spending millions on research to get a paper written saying, "Yeah, we could probably do this."
