    I read in July's Popular Science that Bart Rutan's SpaceShipOne is designed to essentially fall back to earth rather than follow a glide path. The idea was to avoid having to install expensive and heavy avionics and controls to stabilize the craft and to reduce heating.

    I always thought the Space Shuttle followed a glide path to reduce heating, yet it reaches 3000 degrees F. Rutan's ship is only supposed to reach 1000 degrees, and he uses a slathered on heat shield over a carbon fiber body.

    Would it heat less because it comes down quicker and so has less time to build up heat? I thought the straight fall would increase the heat, not decrease it.

    Also, X15 pilots have said the 3.5 g's was hard on their hearts. SpaceShip one is supposed to produce 5.5 g's on re-entry. Does anyone know what's acceptable in g forces?

    As I understand this (which may be wrong) SpaceShip1 avoids reentry heating because it's flight path goes straight up until it runs out of fuel then it falls straight down. So it starts it's reentry at near zero velocity instead of orbital velocity of 17000 mph and doesn't have to deal with high heating from air friction.

  3. #3
    Yeah, it's the orbital velocity that really increases the heat problems for returning spacecraft. If they could decellerate themselves by 17,000 kph so they're just hovering above the Earth, then they wouldn't really need heat shields, but then they'd probably need enormous fuel tanks to pull that off.

    I think a lot of people believe that once the X-Prize is awarded, then private human spaceflight is just around the corner, but the reality is that achieving orbit is insanely harder to do than just reaching 100 kilometres of altitude.

  4. #4
    Okay, I talked to Burt Rutan and here's what he had to say:

    The sub-orbital SS1 goes only Mach 3.5, much slower than the Mach 25 needed to orbit the earth. The shuttle decelerates during entry for more than 20 minutes, while the SS1 decelerates for only about 70 seconds. The 5+ g of SS1 deceleration is momentary and due to the reclined orientation of the pilot it should be no more uncomfortable than typical maneuvering in a jet fighter. Burt
    So, there you go. Should be a very relaxing descent. ;-)

    That is so cool, Fraser, that you call up Burt Rutan. Thanks for the answer, and thanks to all for your contributions as well.

    Perhaps there will be some more posts relating to the X prize and this thread will stay open.

    Appropos X Prize...it
    would be indeed interesting to hear from
    Peter Diamandis as to
    why one team was recently
    dismissed from the
    competition because they
    were proposing a
    non-rocket approach:
    these people should have
    been encouraged to try
    ( they paid their
    entry fee and were ready
    to give it their best
    shot, and were summarily
    shot down...does'nt
    this kind of lame-ola
    put-down seem disturbingly
    familiar?? Would'nt y'think
    that at this late date
    that no one would want
    to go on record excluding
    any conceivable attempt...
    in a similar vein NASA
    canned the BPP project
    which actively embraced
    non-rocket approaches...
    everybody who knows anything at all about
    space knows you probably
    cannot get there from
    here anyway, but most
    assuredly not using
    a neolithic fire-outa-yer
    butt approach...

    It's Peter's contest and he can accept or reject any entrants he likes for any reason whatsoever. If I was running the X-Prize, I would reject it too.

    I think his concern wasn't about the nature of the propulsion but at the state of their entry - it wasn't a prototype, just a concept using scientifically unfounded concepts. If I say I'm going to built a rocket based on the X-2 (like the Canadian Arrow), and show that I've got an experienced team of engineers on hand, then you should say with a certain amount of certainty that what I'm attempting is going to be possible.

    But if I say I'm going to levitate a team of astronauts through the power of positive thought, you're going to say to me, "prove it." "Show me how you can levitate a person, or a rock, or a piece of paper, or a grain of sand. Do that and I'll have a little more faith that you're on your way to levitating a spacecraft."

    If I was the leader of the denied team, I would take it upon myself to prove that my concept works. "Look, here's a prototype of my spacecraft levitating. Here are the calculations that show this will scale up to hold 3 people." The money they save from their entrance fee will let them build a prototype even sooner.

    To admit an entry would be lend it an air of credibility and legitimacy, and give the team a certain amount of press. A lot of people would think, "the X-Prize is giving this concept their stamp of approval."

    The team is still able to continue working on their prototype and if they complete the X-Prize requirements before any other competitor, I don't see why they can't enter and then embarrass and humiliate "the establishment."

    If you have a theory that goes against the establishment, then the onus is on you to prove your theories are correct. People should never trust a theory on faith, and if you're asking them to do that, you need to brush up on the scientific method.

    Am I right in remembering that the X-Prize has to be won by next year or not at all? If so that should help concentrate the mind on practicable efforts within the currently understood laws of physics.

    It is really good to hear from Burt Rutan. I am totally biased in favour of his system, having enjoyed the visual surprise factor and 'shock of the new', followed by the gradual dawning of the design logic. A work of art, like all his designs. And it flies.

    It would be a great service if Fraser could get on the phone or email to all X-Prize contestants to ask them the question "apart from your entry, which one do you like/ admire most?"

    The thing is, the one which happens to be first to fly and scoop the prize may not be the one to point the way to the best long term route for private independent sub-orbital systems development.

    Yeah, I think it's next year or the prize expires. You want me to call all the X-Prize contestants? Heh, that'll take some time. Maybe I'll do some stories on them, and give them a chance to answer reader questions.

    Most assuredly the X Prize
    is peters pet, and,
    indeed the chances of the
    rejected team fielding
    an actual competitive
    entry was less than zero,
    the problem I have with
    Pete and Co. and ALL of
    the space cadets in
    general is the lack of
    interest in pursuing
    new avenues, especially
    after NASA has smoked
    so many folks futzing
    around with Chinese
    tech eons old and incompetent to take man
    to the stars. Once NASA
    at least pretended to
    have an interest in better
    ways and means, but alas
    the short-lived BPP
    program has been eighty-sixed...by the
    way, from what I gather,
    the prize is only even
    at this late date funded
    by an insurance policy
    which shows how serious
    the spacecadets of today
    clearly are not. DT and
    MS both self-funded their
    ridez, each apparently to
    the tune of TWICE the XP!
    A truly serious prize
    would have been to have
    invited inventors with
    wild ideas to sally forth
    and submit same, to say
    a Freeman Dyson, who
    would encourage his
    daughter to get the
    Valley Boyz 'n' Goilz
    to front the cash to
    try a truly new idea or
    two rather than the
    XP chumpchange rehash of
    the same ol trash.

    Prizes with Xpiration dates ( remember CATS?)
    show lack of faith on the
    part of the fronters,
    the X prize itself was
    not a cash deal, even
    with Tom Hanks and a ton
    of Hollywood heavyweightz
    wanting to fly a measley
    10 Mil was a bridge too
    far...the stars beckon
    but I reckon it won't
    be any of the shallowater
    scuttlefish who will be
    effecting THAT trek any
    millenium soon...

    Hello, chloek9

    You sure said a mouthful. One thing is - in some places I know what you feel. (If I could bring myself to say, "I feel your pain" I might do it, but there are limits.) Another is that I want to have a think about what you say before I say much more.

    And its great to hear Freeman Dyson mentioned. The idea that he should be contacted has been hovering around the edge of mind ever since Fraser's Forum took off. Just so we could ask "what would you really like us to do next, starting off from 2003, not from where things were when you worked on the great exploding starship concept?"

    Philip.

    Did you know that NASA has a division that works on advanced propulsion techniques? I'm not talking about boring old nuclear rockets and ion drives, but they're actually doing research to see if some of the cutting edge physics could lead to advances in propulsion, like dark energy.

    I'm sure Peter would love to see the X-Prize won by a ship flying by anti-gravity. They asked the Hungarians to to demonstrate their technology, and they couldn't.

    I said I would go away and have a think and I have. I don't think any of the criticism of the X Prize amounts to a hill of beans against the fact that it exists and is the greatest door opener to space since Goddard lit a fuse or Von Braun started mixing stuff on his mama's kitchen table or whatever.

    What is a source of pain is that planet Earth doesn't have a single zillionaire who has yet tipped 10m of loose change into the project, but I don't see why that is really a problem, on thinking about it, if the insurance policy does the job.

    What does concern me is what becomes of all the wide range of projects the X-prize has generated after the contest ends. Any thoughts on that one, anyone?

    I would think and hope that these people who don't win aren't exactly going to give up. The prize was the catalyst but once you've started to build your very own sub-orbital space craft it's not like you're just going to shelf it once someone else wins. You're going to fly that damn thing!
    It seems that a few of the entrants are going to finish quite close to each other.
    I also hope that a lot of the entrants go on to start up their own relatively low costing tourism companies. Then the x-prize would have fulfilled its goal. The goal was never to see who could win but to open up the industry.

    I hope you're right, Josh. So if we are going to have a choice of rides, consumer pressure will start to call for a trip which doesn't demand that we have to get too fit. So maybe its about time someone who knows about such things had a go at answering the second part of knealy's question, the bit about g forces.

    Also, X15 pilots have said the 3.5 g's was hard on their hearts. SpaceShip one is supposed to produce 5.5 g's on re-entry. Does anyone know what's acceptable in g forces?
    Does anyone know what's acceptable for ordinarily fit people up to say the age that John Glenn was the last time he flew?

    In response to what
    happens to the also-rans
    after the x prize closes
    out with no winner, I say
    Who Cares. All of these
    projects are simply
    old wine put up in new
    bottles. Space will
    never ever BE done by
    Pyro's. Mark Millis
    gives a crackerjack
    breakdown about what
    has to be done and how
    it
    all comes down to
    propulsion, which is
    energy which heretofore
    has relied exclusively
    on pyrotechnics... and
    from what I gather is
    intended to remain that
    way, and MUST remain so
    as long as anyone with
    a new idea is told not
    to let the door hit em
    in the *** on their way
    out which is precisely
    what happened to antigravity dreamers.
    Of course they lack the
    warez, but then again
    the Rutan clan will never
    do a double hundred clicks
    in two weeks no matter
    how much ca$h Paul Allen
    dumps into the attempt.
    The insurance company
    backing the prize ran the
    numbers and rightly
    concluded that space is
    only just-barely done
    by professionals with
    limitless budgets, what
    amateur is going to do
    it. Its not just the
    first 100 clicks that are
    the real problem, its
    the second...Pete has em
    all in the bag with
    the reprise portion of
    the challenge.

    The ONLY way space will
    be done is when someone
    adopts a first principles
    analysis ( Mark M tells
    the inventor what has to
    be done, and even gives
    broad clues to those
    capable of running the
    analogues, and plying the
    morphs...there are ways
    that no rocket scientist
    could ever dream of since
    it appears to be undoable
    otherwise.) NASA 86ed
    the BPP project for
    good reasons, but should
    not have for the same
    reason the antigravity
    fantasists were barred.
    Every entrant should be
    permitted to fail in the
    process of mounting an
    authentic attempt, and
    not be rejected
    by a rocketscientist who
    lacks the essentialz to
    spot whats wrong with
    every space picture he
    ever saw, or helped to
    create! Jeff Bezos is
    apparently at least looking in other directions
    and thus might-maybe
    stumble across a suitable
    alternative to pyro
    DOA's...if you care about
    space start thinking of
    ways to do it some other
    way than as now its done-
    so fuelishly....

    Hi, chloek9.

    At the moment all we have that can get us into space is the demonstrable fact that in our locality every force usually seems to have an equal and opposite reaction. Are you saying that we shouldn't use reactionary systems at all, and should not go beyond the daytime sky at all until we have mastered the use of antigravity systems and modified our understanding of the laws of physics accordingly?

    Obviously no matter what
    the approach Newton 2/3
    will obtain; all I am
    suggesting is that something other than
    pyro approach be considered, which is not
    being done today--even
    though every rocketeer
    knows that rockets cannot
    cut the distance down
    to manageable proportions.
    When a given approach
    fails to deliver, the
    undaunted start to cast
    their nets into new
    seas in hopes of unearthing something not
    heretofore considered.
    NASA had no real interest
    in BPP from the git-go
    because any approach other
    than rockets carries with
    the clear implication
    that maybe we have been
    all these years maddogs
    howling at the moon, which
    is precisely what the
    result would be were a
    new-non-pyro-thruster
    make its way into the
    arena; which might be the
    case were not for the
    fact that rocketeers
    become obsolete as soon
    as a non-pyro-thruster
    appears, so nonpyroz need
    not apply. How does that
    old line go; << Only a crazyman does the same
    thing over and over again
    always expecting a new
    and different outcome.>>

    I can&#39;t see why NASA wouldn&#39;t want to use a new propulsion technique. The only really feasible one right now is nuclear rockets, and they are experimenting with them. But, nuclear rockets are tremendously controversal. They&#39;re working on scramjets, and even some more experimental techniques.

    A success with a new type of propulsion would revolutionize NASA&#39;s ability to get things into space. I&#39;m sure they would love to move beyond, but they have so many existing obligations and people to keep employed, so they have to fight their current momentum.

    Let us hope that NASA does keep on honouring its obligations even if that does mean sticking for a while to the only proven technology currently available.

    I don&#39;t think that, from a world perspective the problem discussed is within NASA. The problem is that without NASA there is nothing worth getting excited about which is not in some way dependent on NASA technology or funding.

    In other words, the whole planet-wide effort spaceward is dependent on the American taxpayer.

    If every other country had as good a governmental space agency and spent the same proportion of its GDP on space technology as America there would be opportunities for every inventor or conceptualiser of state-of-tomorrow&#39;s-art propulsion systems to get initial project evaluation funding from somewhere or other.

    Don&#39;t hold your breath until that stage and age of enlightenment dawns. However, there is no reason why every democracy in the world can&#39;t have their own national, independent space agency by 2008 capable of evaluating the really way- out concepts and pressuring governments into getting some of their tax take invested into the most promising long term sector on offer at the moment. The X-prize is a great pointer in the right direction - opening doors to public participation and doing things outside the big bureaucracies, governmental or corporate.

    It is not until one
    approaches NASA AS a
    proposer of altflightprotocol and is
    dimissed that one recognizes they, like
    some here, believe pyro
    is the ONLY way to go.
    I think the expression
    is << scriptkiddies >>
    those who embrace the
    party-line with total
    confidence in the right-headedness of the
    prefered protocol in place.
    I would remind all that NASA
    is an organization who
    once was torn between
    two options << Meterstick,
    or, Yardstick, Hmmmmm, oh
    we&#39;ll do BOTH&#33; >> Remember
    the Mars mismeasurement
    mission dismemberment?
    OF course you do. This is
    the same crackerjack operation that considers
    solarsailing a viable option and plans to effect
    a softlanding on Mars via
    bouncing ball.
    Neanderthal approaches
    endemic to the NASA organization is only
    possible when funding is
    as it now is, far in excess of what is actually
    needed were the proper
    apprach adopted. The
    NASA approach is as it
    has always been the
    quintessential example
    of inverse occamism, revelling in the mobettayetbellsnwhistlestheory&#33; NASA should have
    regrouped and retooled
    years ago, should have
    done so out of sheer
    embarassment at being so
    conceptually lame, and substantially
    less than expert in the
    goal acquisition process.
    So long as the uppityupz
    at NASA and elsewhere
    continue to hold that pyro
    is the only way to go we
    will continue to go where
    now we go, in circles,
    local circumferations
    leading nowhere...if only they would sweep the floor&#33;
    Now that BPP is kaput
    where do think the new
    ideas are gonna come from?
    Alcubierre--handsdown the
    jazziest of the technodreamerz, but alas
    a protocol demanding vast amounts of
    truest Unobtainium of all-- Negative
    Energy ( which is...exactly, whaaat???)

    In order to turn this thing around we must look
    to the private sector,
    which means USns here.
    ALL the various space
    interest groups need to
    unanimously demand the
    institution of a civilian
    version of BPP, an open
    solicitation of newideas
    with a reasonable Prize
    ( 1 Billion is low but
    should be do-able and
    should be done. Bill(ionairehead) Gates
    could do it alone...).
    The military has to be
    kept out otherwise newtek
    will be ripped by whatever
    branch of the government
    first gets their
    hands around the inventors neck&#33;
    For those unfamiliar with
    the realities of inventing
    far-out propenergy tech
    Google patent secrecy and
    you&#39;ll immediately see
    why pyro rulez&#33; Always
    has, probably always will&#33;

    Hi, chloek9. You state :
    It is not until one
    approaches NASA AS a
    proposer of altflightprotocol and is
    dimissed that one recognizes they, like
    some here, believe pyro
    is the ONLY way to go.
    If by "like some here" you mean persons within the borders of Fraserland it would be good if you could name names and give details of the places in which their views can be found. This would help a lot in getting a serious discussion going with them. One thing that seems certain is that, looking at the time available, there is no real prospect of a non-rocket winner of the X-prize. Getting the independent (non-governmental, non-megacorp) space sector over this first hurdle may seem a small step to some people, but it is surely the next one to take in improving on some of the not quite perfect choices of way to go to spacefly that have been made by the mere mortals thus far.

    No gainsaying that it
    is unlikely that any
    non-pyro player will
    bag the prize since no
    non-pyro will be
    allowed to participate.
    And here&#39;s why...just
    suppose for the moment
    I cook up a new device
    which is non-pyro,
    probably it is very
    quiet, << stealthy >>
    as they like to say,
    whatcha think the
    chances are before
    Pete notifies the fedz
    who will, descend and
    and push the kill-switch.
    I&#39;d do the same in their
    place. Since 911
    even rubber-rafts have
    been secretized. Even
    Pyroz are concerned,
    Dennis T has reluctantly
    decided to re-enter the
    rocket arena this time
    as a player and not a
    rider...he has several
    times gently suggested
    that it ain&#39;t real likely
    that the fedz are going
    to yield the high frontier to competitors
    who can only realisticly
    do space at a profit by
    fielding wholly new
    mechanisms, which means
    NONPYRO...this space
    thing can ONLY work when
    all the spacecadettes
    put their little heads
    together, lean on the
    Gates&#39; Hanks Spielbergs
    Paul Allens etc etc to
    kick in some major bucks
    to fund a Billion Dollar
    building fund for a slamdunk winner AND
    guarantee that the project will be done
    off-shore so as not to
    << violate >> US aerospace. You do not
    have to be a UFO nut to
    suspect that there must
    be a better way of
    doing this stuff, and if
    you are one who wonders
    how those fakers came
    up with all those odd
    objects maneuvering with
    such consumate aplomb
    topside, noiselessly,
    then I guess you gotta
    conclude that its already
    been done, just not by
    US...not yet, and at the
    rate things are progressing, not ever&#33;
    So long as we hand out
    prizes to amateurs for
    joyriding joyriding will
    be regarded as a worthwhile pursuit...which
    is why NASA is still
    afloat....

    Hello, chloek9,

    I&#39;m impressed by the broadminded nature of your analysis. Being able to be equally negative about both NASA and the X-prize folk shows an extraordinarily balanced approach.

    But of course, they all stand condemned on account of still using old-fashioned rocketry to take us above the atmosphere.

    You believe that we should cease and desist from all space travel now, so that we can concentrate all our efforts on developing a better way of doing the job that has greater potential in the long run.

    To me that offers up a big clue that you must know something we don’t about a soon-to-be-revealed novel system for overcoming the effects of gravity maybe or of giving objects a really impressive velocity safely and cheaply.

    Now might be as good a time as any to share the news with us. Once its in the public domain loads of investors will rush to help in a totally altruistic way and all governmental agencies everywhere will just have to accept that once every one on the UT Forums knows the technical details it just won&#39;t be possible to suppress the technology or keep it for their own dark purposes.

    Also, if you hurry, there might just be time to get together an X-prize entry, although whoever gets their name on this new system won&#39;t have the spare time or any necessity to pick up the cheque

    Being clearly in the
    minority in having less
    than no enthusiasm with
    pyro approaches to doing
    space, and indeed I am
    not a fan of Sean or Pete&#39;s transfixtion with
    blastmode...and since
    this seems to be held to
    be the only approach, then
    it shall remain the ONLY
    approach actually deployed. This will not
    change so long as alternative approaches
    are summarily dismissed
    from competing in the
    Rocketeer Prize ( aka X ).
    Even in the unliklihood
    that anyone IS able to
    do the required double-boost this
    is unlikely to usher in
    a new era in spaceflight
    since the challengers are
    simply puddlejumping and
    can in no way be construed
    to be spacefarers-any
    more than NASA is doing
    manned-space. This might
    change IF guys like Bezos
    can resist pyro and seek
    after a new piper to lead
    the way into space...otherwise it will
    be the proverbial: same
    &#39;ol, same &#39;ol&#39; the only
    news being when theres
    the inevitable crashnburn&#33;

    Hi Knealy

    Regarding your initial questions and the first responses to them from mto and fraser it seems clear that it’s a good plan, when considering the problem of getting down from space to a gentle touchdown, to divide it up into bite-size chunks.

    If you get rid of unwanted velocity by means of aerobraking in the planet’s atmosphere you still have a chunk of potential energy to dispose of before you arrive at sea level or whatever is the altitude of your landing or collision point on the ground.

    Below is a recent report on work currently being done looking at an old idea with the benefit of 21st Century know-how to investigate the long-evolved principle of the wing to fly a life-support capsule back to home base after a trip into space:
    Starchaser Complete 2nd Successful Flight Test of Rocket Capsule.

    Starchaser Industries have successfully completed two manned parachute drop tests of their NOVA 2 rocket capsule.
    The manned drop tests were carried out at the Red Lake drop zone in Arizona USA on the 22nd and 24th July 2003. The capsule was deployed from the rear cargo door of a Fairchild C123K aircraft at an altitude of 10,000 feet.
    The capsule was put through a number of manoeuvres during its descent to fully validate the steerable ram-air parachute canopy that made it possible to fly the craft like a glider. Nova 2 was then brought in for a precision landing. Steve Bennett, Managing Director of Starchaser Industries, said; “We are pleased with how the capsule has performed, we’ve completed two very successful flights. These drop tests mark a significant milestone in Starchaser Industries manned space programme. We have proved the different key systems in our rocket programme and now have the technology to push forward in our bid to win the X PRIZE”
    Weighing in at 250 kg and measuring 3-meters in length, the single seat Nova 2 capsule has become Britain’s first manned rocket capsule and has been developed to test a variety of systems for use in project Thunderbird; Starchaser Industries entry into the US &#036;10 million X PRIZE, which is on offer to the first non-governmental organisation capable of launching three people into space.
    Steve Bennett is available for comment following the success of the manned drop tests, video footage and digital stills are available, please contact Lee Kirby on 08700 278766288 or email lee@starchaser.co.uk
    Once upon a time the Americans and possibly also the Russians looked at this possibility using the materials and control techniques available half a century or so ago. One of the many good things flowing from the X-prize competition is that a whole broad range of possibilities can be considered, or reconsidered within the independent space sector. As they would have said back in the first blaze of glory of space exploration – cool. Just as we can now say again, as we all work to initiate space travel&#39;s second stage ignition, using, of course, whatever available technology anybody is prepared to let us know about. Excellent.

    Hi chloek9,

    Please do something for me. On the most recent Universe Today News slot, take a look at the picture of SpaceShipOne and then let us know - even for you, the most noted pyrophobic of our day- isn&#39;t that just the most beautiful sight, SpaceShipOne carrying out its first drop test successfully against a lovely blue close-in-to-the-planet sky?

    Even in the most tightly policed command economy I can&#39;t imagine Burt Rutan and his team being prevailed upon to lay off what they are doing and spend their time working on the Hungarian anti-grav system or other advanced solutions to the problem of getting from down here to up there. They are not consuming resources that could be redeployed to other projects.

    Let us suppose that in twenty years time Burt Rutan&#39;s hope has come true:
    Our message at the April 18th 2003 unveiling of the Tier One program
    Flight research has always been Scaled Composites&#39; forte. For the 21 years since Scaled&#39;s founding, we have designed, built and flight tested 23 unique manned research aircraft types and developed over 40 unmanned products. Counting the homebuilt and milestone aircraft developed earlier by Rutan Aircraft Factory, 38 different types of Rutan-designed manned aircraft have flown research test programs. None have had a significant accident or pilot injury during flight test activity. Our flight safety approach of "question, never defend" has allowed us to take courageous steps by safely flying new ideas and new performance envelopes. We are now focusing on the big step of developing a high-altitude supersonic light aircraft. This program, if successful, will result in the first non-government manned space flight (above 100 km altitude).
    Sub-orbital manned space flights have been done before by Redstone - Mercury in 1961 and by the B-52 - X-15 in 1963. Even though the experience, as described by Alan Shepard, Gus Grissom and Joe Walker was awe-inspiring, sub-orbital space flights were ignored for the next 40 years. The view from the apex of a sub-orbital flight is similar to being in orbit, but the cost and risk is far less.
    Our goal is to demonstrate that non-government manned space flight operations are not only feasible, but can be done at very low costs. Safety, of course is paramount, but minimum cost is critical. We look to the future, hopefully within ten years, when ordinary people, for the cost of a luxury cruise, can experience a rocket flight into the black sky above the earth&#39;s atmosphere, enjoy a few minutes of weightless excitement, then feel the thunderous deceleration of the aerodynamic drag on entry.
    Our plan involves flight in a 3-place spaceship, initially attached to a turbojet launch aircraft while climbing for an hour to 50,000 feet, above 85% of the atmosphere. The spaceship then drops into gliding flight and fires its rocket motor while climbing steeply for more than a minute, reaching a speed of 2,500 mph. The ship coasts up to 100 km (62 miles) altitude, then falls back into the atmosphere. The coast and fall are under weightless conditions for more than three minutes. During weightless flight, the spaceship converts to a high-drag configuration to allow a safe, stable atmospheric entry. After the entry deceleration which takes more than a minute, the ship converts back to a conventional glider, allowing a leisurely 17 minute glide from 80,000 feet altitude down to a runway where a landing is made at lightplane speeds.
    Our concept design work began in 1996 and some preliminary development began in 1999. Our full development program began in secrecy in April 2001. This extensive experimental research effort is a complete manned space program. It consists of all new hardware including a launch aircraft (the White Knight), a three-place spaceship (the SpaceShipOne), a hybrid rocket propulsion system, a mobile propulsion test facility, a flight simulator, an inertial-nav flight director, a mobile mission control center, all spacecraft systems, a pilot training program and a complete flight test program. All our hardware components are full-scale, full space-capable performance, not mockups or interim vehicles.
    The hardware, technical descriptions and a flight demonstration of the White Knight were revealed to the press on April 18th. We are now back into hiding, to complete the rocket development and flight tests. We will provide progress reports monthly via test reports posted in the "test updates" section of this site. We will again invite the press when we fly the first flight above 100-km altitude. This milestone will be significant in that it will represent the making of the first non-government Astronaut, and it will be flown on a system that shows the level of affordability needed for future space tourism.
    I strongly feel that, if we are successful, our program will mark the beginning of a renaissance for manned space flight. This might even be similar to that wonderful time period between 1908 and 1912 when the world went from a total of ten airplane pilots to hundreds of airplane types and thousands of pilots in 39 countries. We need affordable space travel to inspire our youth, to let them know that they can experience their dreams, can set significant goals and be in a position to lead all of us to future progress in exploration, discovery and fun.
    Burt Rutan
    By the time the Hungarian - or some other exotic system - is up and running and ready to go into production thousands of plain folk will have home recordings of their trip or toedip into space and be much more inclined to vote for budgets for the way-out systems than they would be if we all just gave up space exploration until such time as the really effective systems are ready to roll.

    This is a wonderful, active forum...

    Of course we should be looking at new concepts for propulsion, transport or re-location whatever it might be. The immediate problem is should I not drive my car until Hydrogen Fueled Engines are available? I think not. The roaring beasties must continue to be used for productive space programs until alternate forms of propulsion (or relocation) are developed. Now it was 50 year to the day nearly from the first test of Goddard&#39;s rocket motors in Worcester Mass to the landing of Apollo on the moon. The period of development for new technology may not be as long (could be longer even&#33 but it will be a period of otherwise inactive space exploration if we decided to drop "pyro" of a sudden.

    The "use it before it is ready and tested" syndrome is universal in the arena of Civil Experimental Aerospace. I have a test report of one static test of an SSME (Shuttle engine), it is 250 pages long&#33; It is longer than all the combined websites full of information on the X Prize, likely. Safety testing is rarely done and "off-limits" testing never. A "complete" development job is years even in the planning.

    But it has not stopped us before. But lacking a concept, even (is that true?), I see the prediction of a working method of non-pyro space launch being impossible to nail to a date, a year or even a decade.

    Given one, you will see a huge rush to employ as in the search for "zero point" energy.
