NASA's New Space Wheels

jvarsoke writes "ABCNEWS.com has an article on proposals for NASA's next generation Space Shuttle. But the replacement for the 1970's era wonder look a bit like a step backward baring one exception. Choices are a splash-down capsule, a"half-cone lifting body" (sounds bumpy), and two aircraft landing types . . . and what's that in the upper left corner. Could it be? The Farscape 1 module?"

  2. Upper-left isn't New by ClubStew · · Score: 4, Interesting

    As much as I like(d) Farscape, the upper-left design isn't new. It's actually been around a while, as well as a few variants (like the exact same thing with the wings not turned up). Some designs were bigger - presummably to hold far more cargo - and some were smaller - designed only to carry a few more people than currently possible.

    With new pressure on NASA, news ideas are cropping up about using the old Saturn Vs or new variants to carry only cargo and then to taxi people into space using some of the designs here. It may be safer, but will it cost less? Taking a New York taxi a single mile is expensive enough! Imagine the fare on this taxi (and their "luggage" going in a separate one).

      Small problem with the Saturn Vs. They don't know how to make them anymore. It'd take about as long to figure out how they were built in the first place as it would to design a new one from scratch.

      But yes, having at least two types of vehicles would be ideal: one for heavy cargo lifting and the other for crew transportation. In fact, I think that was the original idea. The shuttle was a kludge by NASA to meet political/economic/technical constraints from the Nixon administration and the military. For more detail check out Chapter 1 of the CAIB report, or one of its references on the subject.

      That's an urban legend. We know exactly how to build a Saturn V. The plans were not lost, nor was the knowlege needed to build them lost.

      The problem is that many parts are not available anymore. 35 years ago, guidance equipment used funny things like vacuum tubes. Events in the launch weren't controlled with computers, but with things called 'sequencers'. Some materials used in parts of the rockets aren't made anymore, because improved materials have been developed.

      So, we could fly a Saturn V if we wanted to, but before that would happen we would need to redesign many systems on the rocket to use modern technology. Nobody is going to build a vacuum tube factory to launch a Saturn V; they're just going to redesign that piece to use a modern computer instead.

  3. Does the shuttle problem really limit the ISS? by frovingslosh · · Score: 3, Interesting
    A Soyuz craft is always docked at the ISS as an emergency escape system if needed. And since the Soyuz can only carry three astronauts, the ISS can only be staffed by a maximum three-person crew until another escape option is available.

    Given how long it takes to ready a shuttle for flight and that there was certainly not always one standing by ready to go up, this 3 man limit was just as true before the last shuttle disaster as it is now. Why were there more than 3 people in the ISS crew before but there can only be 3 now?

      I guess this isn't really discussed much, but the whole 'Shuttle == lifeboat' thing is only really a big deal because the U.S. and U.S.S.R. and other countries couldn't come together and agree on a standard docking technology ... so the ISS has a couple different types.

      The shuttle is on standby for 'rescue service' only when it is *attached* to the ISS itself. In other words - there can only be, at a time, enough ships to take everyone on board back home to Earth.

      The ISS can't accomodate more than 2 Soyuz docking scenario's - 1 for a crew return module, and the other for the Progress supply vessels.

      The 'other' docking capabilities on ISS are only for the Shuttle ...

  7. Why use wings on a space vehicle? by apsmith · · Score: 4, Interesting

    If you're launching vertically, the wings give you no extra lift capability. While you're in space, the wings are just dead weight. When you aero-brake in the upper reaches of the atmosphere, the wing edges are where the bulk of the orbital energy gets dumped and has to be dissipated - Columbia's problem obviously was with a wing edge. The only time wings have any advantage is in the final descent stages, where you get much greater maneuverability and a gentler approach and landing - and it looks cool too. But parachutes and retro rockets as used by Soyuz, or just parachutes as used by all the US manned flights before the shuttle, seem to work well enough.

    Mass estimates come in at about 3 times higher for a winged vehicle than a capsule; that's from experience with the Shuttle and European, Japanese, and Russian winged vehicle designs. Is the maneuverability advantage and slightly lower G-forces on re-entry sufficient justification for the vastly greater expense?

  8. -why- nasa was 'farting' around... by *weasel · · Score: 3, Interesting

    because it's a heavily politicized bureaucracy.

    the capsule replacement was always intented purely to support a low earth orbit space station. a space station that congress didn't want to build. so the ultimate craft was designed to land like an airplane, and featured some fudged cost-effectiveness numbers so that it would be popular enough to greenlight. the resulting bureaucratic design being the cause of countless safety failures and unnecessary risks.

    This BS ruined our capability to do much of anything for 20 years while we floundered until the ISS rekindled public interest in its primary function.

    We got to the moon in 10 years because the people (and thereby elected officials) were behind it. NASA either has to fix its bureaucratic problems (impossible), privatize the space industry (desireable), or rekindle public interest in beating the Chinese to permanent moon settlement (short sighted, too expensive).

    Look at the smaller cheaper autonomous initiative (good idea) at NASA that was popularized with the Mars Rover, and was subsequently killed in its crib by the follow-up failure of the polar lander (tragic).

    The true irony is that NASA is organizationally incapable of doing things fast, or cheap, as the polar lander should have shown. All that money, all those procedures, committees, and double-checks - and still a small problem got by and resulted in the loss of a $100 million dollar craft and the priceless research it could have done.

    The best solution is for space to become privatized. Public money is best spent elsewhere, and private industry is more suited to rapid expansion, evolution, and reaching cost effectiveness. Look at what the privatized airline industry did in only -50- years after the Wright brothers first flew. From Kitty Hawk to Chuck Yeager in nearly the same amount of time that we've been to the moon and done nothing.

    Why should we continue to let Boeing and the like purely profit from programs like the x34 which get cut before they can produce. Why not share risk/reward more?

    Consolidate the agencies with control over spacecraft (to make privatization pluasible), set rules regarding space related patents (to ensure that tech falls to the public domain quickly), and set -international- rules for extraplanetary rights and coordination.

    Just a couple of points to consider: "60's" style rockets are cheap to operate. They also actually have enough thrust to lift themselves plus a cargo against earth's gravitational pull, unlike an ion engine.

    NASA is falling behind because they are going for glitz and glamour, instead of economy and reliability. Back in the Apollo era, glamour and the prestige of being first was what the space race was all about. These days, the space race is about business and economy: GPS, satellite TV, weather monitoring, etc. NASA is running the wrong race, and the shuttle was a bold step in the wrong direction. It costs ten times as much per kilo to launch a cargo on the shuttle, as it does on the ESA.

  11. Once again here is a possible answer... by JohnnyCannuk · · Score: 4, Interesting

    From a post I did about 3 weeks ago:

    I don't know why NASA or an areospace company (Macdonnell Douglas, are you listening?) is not considering revitalizing the Delta Clipper. It was a capsule shaped Single Stage to Orbit (SSO), re-useable space vehicle that was actually built and was flying throughout the 1990's until an unfortunate accident destroyed it. Apart from the strut breaking that caused it's destruction (an engineering problem that is likely easily fixed), it performed exceptionally.

    Consider the costs of revitalizing this "existing" project compared to re-designing and re-creating a new shuttle from scatch. Which do you think is cheaper? The Delta Clipper allowed for totally controlled flight to and from orbit, a lot safer it seems, than an uncontrolled glider.

    This idea seems to have the best of apects of what /.ers and other have been saying - it is a "capsule" so it is more efficient in space and it is a Single Stage to Orbit vehicle with the safety of completely powered landing and flight in the atmosphere. I would expect that Macdonnell Douglas could have a prototype built and flying again in 6 months and that, with enough engineering and money, a production model could be built in 2 to 3 years.

    Can the other four say that?

    Hell, strap on a new areospike engine and NASA might actually enjoy a few years of spacefaring success, like they used to in the 60's.

      McDonnell Douglas is not listening. They were bought out by Boeing, and now Boeing is more interested in their own solutions than in SSTO. By the way, to say that the Delta Clipper was "flying throughout the 90s" is rather an exaggeration: the testing program was going well, and it did get off the ground, but never more than a low hover. It would take a hell of a lot longer than 6 months to go from that smaller-scale prototype to a flying production model, though.
