Personal Spaceflight Leaders Form New Federation

Neil Halelamien writes "A number of entrepreneurs in the nascent commercial space industry are establishing the Personal Spaceflight Federation, an industry group which will work with federal regulators to come up with standards to promote crew and passenger safety. The founders include both suborbital and orbital spaceflight entrepreneurs, such as Armadillo Aerospace's John Carmack, Scaled Composites's Burt Rutan, SpaceX's Elon Musk, and t/Space's Gary Hudson. Commentary available on MSNBC, Space.com, and Space Race News. In related news, NASA is looking at commercial options for resupply of the International Space Station."

      > Suborbital flights have the possibility of leading into full blown orbital visits

      Not from any direct descendant of SS1, I'll tell you that much. Heavy tank mass + low ISP engine design = Not Going Anywhere. They'll have to start from scratch with, as a bare minimum, a non-self-pressurized higher-ISP oxidizer. This in turn will not only require a radical redesign of the entire craft (everything except for the cockpit - but that will have to change for othre reasons, discussed later), but will involve the use of at least a single stage turbopump. Even the simplest of turbopumps are rather nasty beasts, with seals that can fail, whole additional engines and turbines just to spin the thing, stringent materials requirements, etc. However, even if he used LOX (which would require dealing with all of the risks and costs associated with working with cryogenics), I'd be surprised if a simple single stage turbopump plus polybut would get better than, say, 320 ISP and a rather weak thrust. You'd realistically only get to orbit with a payload on that kind craft with multiple stages, and even then your payload fraction will be really awful. You generally want at least a LOX/Kerosene level of performance to compete.

      Then there's the materials factor. A fiber vehicle just won't cut it (yet, that's where Rutan's experience lies). It doesn't come even close. You either need a good hot frame (titanium plus leading edge shielding plus internal component insulation, for example) or cold frame (aluminum-lithium or other good aluminum alloy plus an extensive TPS that a company like scaled couldn't dream of making on their own - I doubt they could shield a hot frame well enough on their own) design. The higher operating temperature of the engine plus using a better oxidizer will mean a lot more corrosion, requiring a lot more complex and expensive engine maintenance (a common killer for reusable craft). The cockpit is completely off for reentry; those windows are nice for suborbital, but they'd be serious weak points on *real* space travel.

      Then there's the general issues with real orbital flight. You have to handle *everything* needed to keep people alive for long periods; even developing a toilet that will work in space (and all of the associated infrastructure to run it) is no easy task. SS1's hydraulic controls suddenly become serious liabilities: in space, your craft cools and heats in dramatic cycles depending on whether you're exposed to the sun. Hydraulic lines, tanks, and actuators all require an extensive system of heaters, sensors, and sometimes cooling. Maintenance of this system on reusable craft, like the shuttle, is very expensive. Air quality maintainence becomes a lot more complex - and if you want to be truly safe, you're going to need to do spectral or other analysis on the air to determine atmospheric composition percentages. They'll need changable CO2 scrubbers, nitrogen and oxygen balance, etc. Temperature regulation in the cabin can get complex, since you can't just "run an air conditioner" or whatnot to cool down. If you want a direct heat pump, you need a very good radiatior outside the craft; this generally isn't realistic. Consequently, heat regulation is generally done by using water or cryogenic fuel in a closed loop; any cryogenic boiloff then needs to be vented. Naturally batteries are insufficient for how long you're in orbit; you need fuel cells or generators designed to operate in the hostile environment of space. Etc.

      Then there's problems with the "carrier" method of launch. Unless they get some serious ISP improvements, the size of the White Knight would scale beyond any realistic level. Unless they plan to launch from a Cossack (the Buran Shuttle's carrier, and largest airplane ever built) in order to simply take a few people to orbit, they *have* to get some serious ISP improvements or switch to ground launch.

      I could keep going with the issues, but I think you get the idea: Orbital and suborbital spaceflight aren't even remotely the same sort of beast.

He has a small team and proportionally small resources. As a consequence, he achieved a proportionally small feat. I believe I've fairly demonstrated the scale of difference between suborbital and orbital, but I could go on if you'd like; if you think that one can go from the proportionally easy challenge of suborbital to the complex challenge of orbital without an equivalent scaleup in resources, I'd like to know how.

      Rutan is not developing the figurative machine tools; NASA is. Rutan does not have any sort of effective R&D budget for that. Rutan is taking what is already known, and using the proportioanlly low-cost components (all that he can afford) and low-labor, undiversified manufacturing (all that he has the human resources for) to produce a low performance craft.

      > NASA in the 1950s couldn't make ANYTHING on their own.

      Amazing what a real R&D budget can do, isn't it? Rutan doesn't have one.

      Most of NASA's progress - the "machine tools", to reference your earlier analogy - was based on hundreds of papers representing large amounts of research released every year like you find here:

      Luckily for him, CPUs are cheap commodity components. Unluckily for him, high performance rocketry equipment is not. That's why he bought such a poorly performing engine from SpaceDev. It's not much more than a hollow tube partly filled with rubber with a de laval nozzle at one end (flaring to a bell) and an ignitor at the other. A ball valve and small actuator connect to a nitrous tank. That's all it is; that's why Rutan could afford it; and that's also why it will never scale.

      > But serious strong points when it comes to selling suborbital space tourism.

      Indeed they will be. I think Rutan has the low-suborbital market down for years to come (high suborbital (i.e., your flight lasts for hours instead of minutes)? Real rocket companies (still private, mind you) are probably more likely to win that slot.

      However, I'm not talking about suborbital; I'm talking about orbital (orbital spaceflight, not Orbital, the company - one of many private companies that make *real* rockets that most people don't know about).

      > I think for a 2-3 hour orbital flight

      Rutan will have some significant trouble scaling up even that far; an SS1-style craft certainly won't do it. A "real" rocket company like SpaceX or SeaLaunch or whatnot would be in a much better position to take a market like that with their existing infrastructure.

    The Russians are going to be showing a full scale model of their Kliper reusable capsule at the Paris air show this June.

    This is their planned replacement for the venerable Soyuz. It will carry 6 astronauts or 700 kilos of cargo. The article sounds like they are a little cagey on the schedule, it just says a few years. I'll bet you they have a manned launch about 5 years sooner than the CEV.

    If they hang one of these on the ISS as an emergency vehicle they will enable bringing the ISS up to nearly its planned manning level, and might actually allow people to do research on the thing, instead of spending all their time maintaining as the 2-3 man crews have been doing.

    Kind of looks to me like Russia is planning to go it alone when the U.S. gives up on the ISS and the shuttle. The other source of friction is that since Russia is trading with Iran and the U.S. has embargoed Iran NASA is officially forbidden from having any financial relationship with the Russian Space agency. I wonder if they will have to paint a white line down the middle of the ISS and have a U.S. half and a Russian half :) Or more realisticly the Russians can just undock the modules they built and control from the NASA tidbits and let them burn up. Their modules are a full, self contained space station, a Mir2 if you will and they don't actually require the American parts.

    For comparison to Kliper, the CEV is going to have Lockheed and Boeing launched an unmanned, half baked prototype in 2008, pick a winner between the two and wont have a manned launch, probably just to LEO, before 2014 at the earliest.

    By contrast NASA went from a nearly standing start to putting a man on the moon in way less than 10 years in the '60's when it had never been done before. In summary, NASA, Boeing and Lockheed are today, officially pathetic. As nearly as I can tell the CEV, and the Bush Moon/Mars initiative is mostly just an excuse to pump money in to the pockets of Boeing and Lockheed and put the milestones that count so far out there it will be a miracle if they program isn't killed before they actually have to do anything serious for the subsidies.

    Let's face it, sticking people or anything else on top of a big firecracker is always going to be really dangerous and really expensive. The space elevator will be cheap (over the long haul) and very safe in comparison.

    Why don't we just concentrate on getting that built? Then all you need is little orbital ships that can ferry people and crews around. And since these orbital ships can either be ferried by the elevator or built in orbit from ferried components, you're talking a significantly safer way of dealing with space in almost every way.

    Yes, we have some advances to make to actually build it, but if we spent nearly as much money on researching the needed advances as we do on maintaining the space shuttle fleet, we'd probably have the research done pretty quickly.

  17. Commercial space travel by uberdave · · Score: 5, Insightful

    Shortly after the WW1 and before commercial air travel became popular, "barnstorming" aviators would "buzz" small towns or county fairs, using of one of the local farm fields as a temporary runway, and offer airplane rides to customers. These flights didn't have a "real destination". The purpose was not travel, but experience.

    The emerging space tourism industry is about to begin it's "barnstorming" days, selling rides for the experience, not the destination. Initially it will only suborbital flights. Soon, they will be competing for altitude and duration of weightlessness records. Then someone will start offering a "once around" package.

    Space flight as a means to an end is not going to happen until you have and end with meaning. Why "sit on a thousand pounds of explosives" to go to the moon? There's nothing there but grey rocks and dust. Mars, same thing, but the rocks are red. There's no real destination, no purpose in going except for the experience of being there, and that won't change until we get some sort of permanent outpost set up there.

    Right, except for one thing: Suborbital flight, even doing half an orbit, is a heck of a lot cheaper and easier than orbital flight. 30% delta-V less equates to a huge reduction in required TPS, greatly reduced ISP (and thus reduced maintenance) or greatly improved payload fraction, etc. The difficulty of getting out of a big gravity well scales geometrically with the required delta-V, not linearly.

    Another bonus of suborbital is that you can do a lot more of the work on airbreathing engines - either tow-launch, carrier-launch, launch-and-midair-refuel (i.e., Black Horse, Black Colt, etc), or even surface launch on a craft with both jet and rocket engines.

    Lastly, since it's in a suborbital flight path for so short of a period of time, you don't have to worry so much about thermal or atmospheric regulation as you would for a true orbital craft that would be up there for days. This could be an especially big advantage for simplifying hydraulics (although I'd like to see spacecraft move away from hydraulics anyways... ;) ).

    Lastly, you get much better economies of scale. All in all, I'd expect travel on a suborbital liner to cost at most 1/20th as much per kg if built properly, and probably much less. You might even be able to go under 100$/kg if you got enough passengers. No matter what, though, probably way too expensive for ordinary commuter flights :P It probably could fill a niche industry - a combination of space tourism with Earth tourism.

  19. Concept images of Virgin Galactic space station? by FleaPlus · · Score: 2, Informative

    Virgin Galactic's web site has a new computer-generated
    video available, which shows the full flight profile of the Virgin
    Galactic craft. It's available for streaming at the bottom of this
    page:

    I took the liberty of capturing just about all the key frames from the
    video, and posting them on the web:

    The most interesting images are seen right after the question "What
    Next?" flashes on the screen. These are images of what appear to be a
    Virgin Galactic space station, with a SpaceShipOne-style craft docked.
    Of course, they're probably complete vapourware for now, but they
    certainly look interesting:
