SpaceShipOne 100 km Attempt Slated for June 21

apsmith writes "Scaled Composites has just announced their first attempt at breaking 100 km, scheduled for June 21. This would make it the first commercial manned vehicle to officially enter space. This is not quite an Ansari X prize attempt since it will carry only one person without the extra mass corresponding to the 3-person prize requirement; they have to give at least 30 days' notice for that. Past flight history is available from their site; the Discovery Channel is producing a documentary on the whole project, 'Rutan's Race For Space.'" Roger_Explosion adds "If successful, the craft - named Space Ship One - will become the world's first commercial manned space vehicle. Space Ship One will temporarily leave the earth's atmosphere, and the pilot (yet to be announced) will experience about three minutes of weightlessness."

    Q: What date and time will the launch take place?
    A: The launch is planned for June 21, 2004. We plan for very early in the morning. Currently we are planning to taxi out for takeoff at 6:30 a.m.

    Q: Why so early?
    A: Mojave is a windy place. It is less likely to be windy very early in the morning. That makes for better flying and launch conditions, and the low sun angle allows better spectator viewing of the high-altitude boost to space.

    Q: Is there any chance that the flight would launch later in the day or be delayed a day or more?
    A: Yes. As with any flight test activity, weather is a very important factor. High winds or very cloudy conditions could change our flight plans. In addition, flights can be delayed for technical reasons.

    Q: What can we expect to see?
    A: White Knight with SpaceShipOne slung underneath will taxi by right in front of the public viewing area. A few minutes later, you will see it take off. For a few minutes early in the flight, you can see them circling overhead as they climb. It takes the pair of mated vehicles roughly one hour to reach 47,000 feet a few miles to the northeast. That is where White Knight releases SpaceShipOne. They are generally easy to follow visually since the White Knight and its chase planes usually make contrails. SpaceShipOne glides for a few seconds, then the pilot lights the rocket and you'll be able to see flames and a rocket exhaust trail for about 80 seconds. There will be a public address system in the viewing areas which will carry the radio transmissions between Mission Control, the White Knight pilot and the SpaceShipOne pilot, so you'll know what is happening.

    SpaceShipOne's flight lasts roughly 25 minutes. It will rocket to space, spend about three minutes weightless outside the atmosphere, then enter the earth's atmosphere in a high-drag configuration. It will glide back toward Mojave, circle overhead, then land directly in front of the public viewing area on the same runway on which it took off about 1 hour and 25 minutes earlier. SpaceShipOne's rocket is very loud but it can only be faintly heard on the ground in the best of conditions. If its reentry direction is aimed away from the airport, two soft sonic booms will be heard. After landing, SpaceShipOne will be towed by a truck to the media area for a brief photo opportunity, then moved to the adjacent public viewing area, then towed back to Scaled's facility. Thus, the media and the public will get to take their own close-up photos. White Knight takes longer to return. It usually lands a few minutes after SpaceShipOne.

    Other aircraft which you may see during the flight include:

    Robert Scherer's Starship (a Burt Rutan design). This plane flies high-altitude chase and carries our company photographer. This is a twin-engine turboprop airplane painted white with a canard near the nose.
    An Extra that belongs to Chuck Coleman, one of Scaled's Design Engineers. This aircraft has been used to train our pilots/astronauts. It is a single engine aerobatic plane painted red and black. It flies very close chase toward the end of the flight to assist the SpaceShipOne pilot in landing.

However, I would presume there is a limit to the number of times this can occur due to dynamic airframe stress fractures and heat-induced stresses in the SRB structure. Anyone know of such limits? How often are the SRBs for the Space Shuttle reused? Is the SRB's exhaust nozzle replaced or is it reused as well? Is it complex or is it an open tube?

      NOTE: Scaled has not released the reuse percentage for its flights. I would presume due to the design that their percentage is going to be very, very high, with only fuel / consumables being replaced and probably a couple of spare parts here and there.

    Since this flight won't go into orbit (or anywhere close to far enough from Earth to ignore it's gravity), the weightlessness effect is simply a result of the flight trajectory including free-fall on re-entry.

    Yep, this is more or less correct, but let's clarify one point. The only significant difference between this attempt (or any similar 100km up-then-down mission) and an orbit mission is how far you fall.

    You can go a thousand kilometers straight up, and fall straight back down, and never go into orbit. You never can "ignore" gravity - even out at the lunar orbit distance, at hundreds of thousands of kilometers, gravity is still a factor. Fact is, that's what keeps the moon nearby.

    An orbit is, essentially, simply falling in an arc that never intersects the ground (or atmosphere). You have to get a whole lot more energy into the vehicle so that the trajectory falls past the planet's "edge" - at which point you end up "falling" forever around the earth. (And yes, for you rocket science purists, you also have to expend some additional energy to reshape the path through which you fall, usually at the highest point of your trajectory, to make the orbit more circular - that's called an "orbit injection maneuver".) So it's not a matter of HEIGHT, it's a matter of which DIRECTION you expend the energy.

    As a matter of fact, if the atmosphere and terrain were not an issue, you COULD do an orbit a hundred feet off the ground. And you could enter this orbit by going straight sideways. It just requires moving a lot faster than a higher orbit. Our current launch profiles are designed to minimize the fuel (and therefore change in energy, a.k.a. "delta-V") required.

    So to wrap up the thought here, weightless is BECAUSE the vehicle trajectory is a free fall (one that's not being modified by expending energy or using winged lift or drag). Doesn't matter whether it's a complete orbit or one that will hit the ground before going around one complete time.

    And here's the most relevant point to SpaceShip One - to achieve true orbit (a true free fall all the way around the earth), quite a bit more delta-V is required - which requires more fuel, which requires more vehicle structure, which increases vehicle weight, which requires more fuel to lift, which requires more structure... etc. (And let's not even THINK about reentry heating yet...)

NASA isn't projected to have a new man-rated vehicle for another decade, and at the cost of BILLIONS. It is likely that before they accomplish that, the commercial industry will catch up and have a 4-man orbital vehicle by the end of this decade.

    Finally, the dollars will be there. Right now, if you asked NASA to get you into a sub-orbital launch, it would probably cost them $100 million minimum in development to get you there. Your price tag might be as high as 10-15 million. Rutan is doing it for less than 5 million (that's including vehicle development) and your price (once operable) will be about $80-100K per launch.

If they get it that low, then space tourism will be the economic demand this industry is hoping. Hell, I would pay $20k to go into orbit!

      This vehicle is a test-craft, much like the original Wright-flyer. It's a proof of concept. It's the next step in aviation.

      And if nothing else, imagine if Rutan offered a kit version, like the Long EZ, that you could purchase for ... say... 20 million.

      I'd start saving my pennies if I were you.

      Also please remember that once upon a time, flying by jet was horribly expensive compared to prop-aircraft, hence the term "jet set" to describe rich people.

      Eventually, development in this area reduced the cost of flying by jet, and now, you can hop a plane to just about anywhere in the world for a reasonable amount.

      Space travel or Suborbital travel will start out expensive, but over time, as there is more development, it will eventually get cheaper.

      I think FEDEX will invest in such a system before airlines do, but if you can get a package from NYC to Hong Kong in 3 hours, it's only a matter of time before companies start trying to get their executives from NYC to Hong Kong in 3 hours.

      SS1 is the start of all this. It's not meant to be the final design of a larger craft any more than the X-1 was the final design for some larger supersonic craft.

      Instead, SS1 is the stepping stone for design work to bring us that larger suborbital craft, that may be based on entirely different technology.

      I hope this answers your question.

    If there is ANYONE that could build the world's first privately funded reusable spacecraft that can achieve low Earth orbit (LEO), it's Burt Rutan's company.

    Scaled Composites could work with Lockheed Martin's Skunk Works division and come up with a low cost vehicle that could be launched on top of a modified 747-200 to carry up to six astronauts and/or its equivalent in cargo to LEO. Unlike the unfortunate X-33 project, this project is probably going to be much cheaper to pull off since the vehicle that actually flies into space will not need to carry so much fuel during its boost phase.

    Funny you should ask. Along with the pilot, the other two seats will just so happen to be occupied by a monkey and a meatloaf! That way, if the space craft blows up, hey, it's only 1 pilot, a monkey and his meatloaf. They just saved 2 pilots!

    To be even more pedantic-
    If you were to orbit the earth at ground level, you could go a little bit slower than orbiting at 100km (ignoring problems like friction and the fact the the earth is not a perfect sphere). Orbital physics are a little counter-intuitive, but you must expend energy - and speed up - to rise into a higher orbit. Yet your angular velocity (the rate at which you circle the center point of orbit) decreases.

    Time for my standard response that makes people hate me for getting them hooked:

    First off, the reason we fly straight up and then sideways is that it's a lot easier to accelerate sideways at 70km than it is at 0km altitude, because of the thinner atmosphere. Since the only significant delta-V in an orbital launch is the tangential component, you can tune your ascent to minimize fuel requirements and save up for the big sideways burn.

    Now, for the fun part: Orbiter is a free (as in beer + SDK for making your own ships) space-flight simulator that is both mathematically accurate and visually stunning. It includes the space shuttle Atlantis (don't even bother starting out with that one, as it takes practice to get to orbit) and some fictitious spacecraft capable of getting you to Mars or even beyond.

    You can even look around online and find add-ons such as my latest favorite, an Apollo mission including a pretty realistic cockpit complete with the Apollo computer system. You even have to do your own LEM extraction and so forth.

    and that says a hell of a lot of interesting things about what Allen thinks is the risk vs. reward ratio in this investment, doesn't it :)
