      Thats because this is a suborbital flight and not an orbital one so there is not the insane amount heat generated when Rutan's craft re-enters the atmosphere.

      Mercury, Gemini, Apollo, Soyuz, etc. did not use tiles. SpaceShipOne is using similar ablative compounds to remove the minor heat that it produces.

      Of course, if they were doing orbital flights where you would have to remove the insane amounts of kinetic energy they would probably use carbon-carbon or something similar. Tiles are too complex a beast for extremely reliable space flight.

      Is there an advantage to orbital flight? Why couldn't an orbiting craft stop orbiting before reentry and return to the atmosphere like SS1? In order to stop orbiting, they have to slow down from very high speed, and that requires getting rid of a huge amount of kinetic energy. In the case of the shuttle, capsules, etc, that energy is just turned into heat by the atmospheric drag. If you want to avoid that heating, you need to slow down in a different way. The only other choice is to use an engine burn, and that is hugely expensive because it means that you have to lift a lot of extra fuel into orbit along with your payload. In fact, it takes as much fuel to slow down as it takes to get into orbit in the first place (unless you get rid of some mass by tossing out a satellite). But carrying that extra "deorbit" fuel means that your original load on the launch pad has to be much much bigger too. It is better to just let the atmosphere slow you down.

    We had a VERY sucessful chat-session during the previous flight on June 21st and expect to have a good round this time for the X-Prize flights. The channel is open to all (we prefer you register/identify your nicks but is not a requirement for this channel). IF any 'over-flow' occurs, a back-up channel will automatically re-direct those as needed. A !news bot (Space.com) and !countdown bot is available.

    We also set another 'special' channel ( #SS1-FltData ) to record/display near 'real-time' Flight-Data from SS1 but the final decision is still not complete and not expected for the first flight-attempt. In any case, we expect to still have some limited data/info available. This channel is to monitor only, no chatting there, unless you are 'voiced'. The #SpaceShipOne channel is for that. ;) You MUST be a registered nick and identified in order to join this channel. There is no cost to register.

    The chat-server is located on the Freenode.net series. Point your chat-client to:

  9. Scramjets have nothing to do with space access by XNormal · · Score: 3, Informative

    Don't get me wrong - the X-43 is a fantastic engineering achievement. It may pave the way for things like a mach 10 airbreathing cruise missile or possibly even a hypersonic jet transport. But it has nothing to do with access to space.

    A space launch is a short acceleration mission. You spend very little time at any particular speed. A scramjet is good for efficient and sustained cruising at a certain range of speeds. It's not effective for takeoff. It's not effective for accelaration to supersonic speed. It's not effective for acceleration from supersonic to low hypersonic. It's not effective for accelerating from its top hypersonic speed up to orbital velocity. It's only good for a specific range of hypersonic velocities.

    Current plans are talking about using at least three different types of engines to make a single vehicle that can make it all the way to space. This is an enormous penalty in weight, vehicle shape and configuration. It's doubtful if a single vehicle can be designed for all these different flight regimes and still be light enough to make it into space at all. But even if it can be done there is absolutely no way it can be cheaper. The development and operational costs of such a complex system will be staggering.

    In short, saying that scramjets are the way to cheaper access to space is a big fat lie and just an excuse for robbing the taxpayers.

  10. Re:but isn't his design a dead end? by Inominate · · Score: 3, Informative

    You are quite wrong.

    Space-ship one is a suborbital vehicle meaning it goes straight up, and falls straight back down. Attaining orbit involves getting that high up, and simultaneously accellerating to some 20,000mph+, a feat which requires a hell of a lot more fuel than SS1 has available.

    An orbit is when you get going fast enough that you fall around the planet, instead of into it.

    There is also the problem of decelleration. The space shuttle has no retro rockets or anything. It uses it's rear-facing orbital maneuvering engines to slow down, and has to turn itself around to do so. Nothing SS1 couldn't do. However, the energy required to slow an orbiting spacecraft down using only rockets is immense. Because of this orbiting spacecraft use the atmosphere to slow down, which at 20,000mph generates temperatures which require special thermal protection.

    SS1 cannot ever achieve orbit. It's roughly the private equivalent of the X-15 project, the beginning of private manned spaceflight.

    All of that said, SS1 cost some $20 million dollars, pocket change to nasa or any military project. I wonder how much the same project would cost if NASA did it. Nowadays NASA is bogged down by bureaucracy, and controlled by PR more than anything. NASA should be dissolved and it's budget used in the form of grants to private space projects.

    Air breathing space craft are still a bad idea.

    The reason is that they produce large amounts of drag due to the large cross-sectional area required to ingest air.

    No, you don't have to carry oxidizer, but you DO have to schlep a big draggy fuselage along with you.
