    I thought they were scrapping the shuttle? This might of been interesting if it was 20-30 years from now and they were taking their "restored 57 Chevy" out into space. Personally I am to the point where these shuttle flights are a big waste of money "if" they are not doing anything innovative to help the next breed of space capable crafts.

      From the Article:
      The shuttle program has 28 flights remaining on its books before the orbiters are scheduled to be mothballed toward the end of the decade. All are in support of the International Space Station, which remains under construction.
      The shuttles are back, but only temporarily. Work on their replacements is likely being done now.

        Replacements for the shuttle won't be flying anytime soon. The X-33/VentureStar was canceled a couple of years ago. The X-38/Crew Return Vehicle/Space Taxi, which was being considered as a crew module atop an expendable rocket, was canceled even though development seemed to be proceeding well.

        And then there is the new CLCS (Command and Launch Checkout System) a replacement for the shuttle launch consoles and computers which was also canceled after 100's of millions of dollars.

        NASA should fund Burt Rutan (if he'd take the money), then something would get done.

        • NASA should fund Burt Rutan (if he'd take the money), then something would get done.

          I imagine Burt's position would be along the lines of: "If NASA would fund Burt Rutan then nothing would get done."

          The reason is that NASA runs on an incredibly high load of paperwork; you spend most of the money they give you just filling in their paperwork.

        • And Rutan has done what that would enable him to get to orbit or survive reentry?

          He competed for a prize for which the requirements were in the range of his experience. I.e., it enabled him to do what he always did, build small craft out of epoxy with normal control surfaces, et al. He didn't even build the rocket engine himself - SpaceDev deserves the credit for that one (although we can go into why SpaceDev doesn't have the qualifications either for the next rocket engine if you want...)

                But neither does it fund the development of new manned space vehicles. It develops them until they get to a point at which they might threaten the entrenched Shuttle/ISS pork barrel, and then cancels the project.

                With shuttle retirement now a reality, maybe this time it'll be different, but I doubt it.

                Personally, I'd like to see NASA scrap the ISS and concentrate on unmanned space science, at which they're pretty damn good. Contract out the probe launches to commercial providers, which they're doing now. And have about $3B/year to use in either doing more science or in actually seeing a next-generation project through to completion.

                I don't want NASA to "fund joyrides". I want the joyriders to fund themselves. Once that happens, the joyriders will produce other joyriders, because people will be making money in space. The more meat you can put up in orbit, the more of the meat's money you make. The price drops, and someday the scientist-meat can afford to go too. (Much like the scientist-robots are flying commercial, rather than Shuttle, these days.)

                NASA's manned programme is a nest of perverse incentives: a space station that does no science, but requires the shuttle, and a shuttle that does no science, and requires a space station. They're both very good at "making money" (in the sense of burning through Congressional appropriations), but so long as the money keeps coming, NASA's manned programme has no incentive either to put meat into space or do science in space.

                So yeah, Burt's a hell of a long way from orbit. But because he's motivated by profit (which he doesn't get if he doesn't build SpaceShip Two/Three), and because NASA has no motivation to do anything other than preserve its current bureaucracy, I'd put even money on Burt getting to orbit before the next-generation Shuttle will. If you give me 3:1 odds, I'd even put money on Burt making at least one orbit before the next-generation Shuttle gets off the drawing board.

        You assure wrong. NASA has done a *huge* amount of R&D in the last decade - in fact, they're the biggest space R&D spender in the world. They've developed dozens of kinds of ion/plasma propulsion systems (and are working on getting a better power/mass ratio). They've developed dozens of new fuels, lightweight alloys, and new structural materials. Heck, even without changing the shuttle's basic design, they've notably upped its payload even while adding in more safety features due to their advances. They've lowered the cost of shuttle maintinance (although its still very expensive, because - cue the "they don't do enough safety work!" people - they go so far as to dismantle the SSMEs each time for inspection, and SSMEs are very complex beasts). Just last month I was reading about a new method they developed for using CVD to deposit a liner on the engine nozzles so that there's no clear surface break for it to erode at.

    • NASA is moving away from the Shuttle... but not for anouther 20-28 missions. There simply is not enough lift capability that can support the current design on the various ISS modules. They were built to fit in the Shuttle and not in another heavy lift booster. My guess is the net present value of the science + ecomonic gain will dip below 0 if the remaining components have to be redesigned. So we need to keep the Shuttle active for most of the remaining build out time of the ISS.

      As usual in capitalist world, they put monetary equivalent for the obligations. A couple of years ago Russia was behind their obligations, which put them at ~$60-70mln in debt. Since they didn't have money to compensate, they used barter. Namely, Russian cosmonauts worked on American projects aboard ISS. I don't know exact figures, but they charged $500/hour or so. Russia have also been repaying their debt in the last months by supplying their Soyuzes. Their outstanding balance became officially $0 after that work they did to fix the break circuit in American segment of the ISS (I read somewhere that they charged 500 of work hours for that job).

      From then on NASA has been falling behind. Since Congress prohibited paying cash to Russia, they will use barter again. Now American taxpayers should expect astronauts to work on Russian projects.

    • One theory I heard often espoused is that its actually all JFK's fault. Basically, the idea is that the moon project resulted in NASA becoming over-obsessed with rocketry instead of developing space-plane technology, and as a result there wasn't the space-plane background ready to design the shuttle the way it really could've been done.

      Rutan's ship didn't go into orbit, it simply went into space and just barely at that.

    • If I remember correctly, his ship never went into orbit and went about 1/7th the height. It also never gets to the shuttles 17,000+ mph speed and thus doesn't have to deal with all that heat slowing down. It also has a small fraction of the amount of fuel. I'd rather they take their time and avoid burning men because they decided they had to hurry.
    • Burt Rutan's ship has never been to orbit and never will go to orbit
      (unless someone builds an orbital vehicle large enough to carry
      SpaceShip One as dead weight to an orbital museum).

      The X Prize was about recreating the X-15 program, nothing more. Nobody
      with a clue would call 3 test flights (two of which experienced
      significant control problems) a step towards anything except more tests
      to better understand what happened. If they really cared about safety,
      they wouldn't have launched again after the 30 rolls
      • "The X Prize was about recreating the X-15 program, nothing more." But at a much lower cost in 2004 dollars than the massive 1950s program, due to advances in technology. Imagine a 21st century space shuttle.
        • There's a good reason that the X-15 cost more: The X-15 was more capable than SS1. Not only could it reach 100km altitude, it could also fly like an airplane at hypersonic speeds within the atmosphere. SS1 just pops up and then floats back down like a leaf. Getting up to Mach 6 in the atmosphere and controlling the flight without melting is probably by itself much harder than reaching the X-prize altitude.

      when it takes Burt Rutan 4 days to get his ship back into orbit Bit of a fallacy here - Rutan is doing nothing even vaguely similar to the Shuttle (or even later Mercury flights).

      SpaceShipOne was nowhere near going into orbit. Orbit requires horizontal speed, not vertical height, and - more importantly - a way to safely bleed off that speed on re-entry without burning or breaking up.

      SpaceShipOne is not capable of going into orbit, and never will be - it has neither the power to reach the Mach 25+ speeds required for orbital velocity, nor the ability to withstand the heating required to lose those speeds on reentry.

      It's the equivalent of the early Mercury-Redstone flights from 1961(Freedom 7 and Liberty Bell 7) - short sub-orbital hops. The difference is that with a new booster (the Atlas) Mercury was capable of re-entry from orbital speeds.

        SpaceShipOne has much more in common with the X-15 from the early 1960s. Both are reusable rocket planes launched from an airplane, both reach the edge of space (about 100km), and both land on a runway. Neil Armstrong actually got his astronaut wings aboard an X-15, not a Gemin
    • Burt Rutan got his ship back into space. He did not go into any kind of orbit. Orbit requires way more energy than spaceship one could ever produce.

    • The Engineers raised concerns but the system prevented them being voiced. Since then they have been very paranoid about any complaints and increased the level of checking.

    The shuttles are masterpeices of engineering.... circa 1980. Unfortunatly they invested $$$ in a short production run vehicle that seems to still serve the original purpose. If you were to start building one new replacement it would take a long time and cost big bucks.

    If they were to start off with a new design they could apply modern techniques/materials to create a lighter, stronger, more reliable system (i.e. a carbon monocot frame, carbon heat shield skin, computers that have more than 640k of ram, etc)

    After working out the kinks on paper they could build a few dozen (price per unit should go down with increased volume) and launch more regularly. But then again, I'm just smoking crack here, NASA will never see that kind of budget again. Unless we can convience the public that Bin Laden is camped out in his secret moonbase.

      Yeah, but they should probably re-think the mission requirements, too. The shuttle had too many mission requirements for one vehicle; it had to bring reasonably large crews (seven people) to orbit and back, deliver relatively large payloads to orbit, and, by the way

      Think again. If I take a thousand dollars in cash and throw it down a sewer drain I don't call it an "investment". The ISS has been so scaled down that even if completed its science value will be negligible. This is a pig in a poke, the countries that have pulled out have done so wisely, and only our pig-headed obstinance (or steadfast resolve, if you're on that side of the aisle) keeps us throwing billions at that turkey.

      "'Disasters' - We've had two. Fewer than the Apollo program. They suck. Really they do. And they have been attributed to the 'make it work anyway' group."

      I am admittedly not a space fanatic but I remember the Apollo 13 cockup -- which didn't kill anyone but really, really should have given the circumstances -- and the Apollo 1 fire, which killed three. 13 had a hardware fault, which is going to happen occasionally despite the best intentions and zero-defect policies. 1 suffered from a combination of poor engineering design (an inward-opening hatch? Oy) and the schedule-pushers whose successors killed the two shuttles.

      Both shuttle accidents could have been averted if the engineers had been listened to by the managers. The Columbia report revealed that NASA didn't learn a goddamned thing from the Challenger disaster and I bet a dollar to a doughnut the Endeavour report will reveal that NASA didn't learn a goddamned thing from the Columbia disaster. (Not to pick on Endeavour, the next killemall shuttle cockup could just as well be one of the other two.) NASA's management culture is not capable of changing.

      "[W]e really need the shuttles flying, if only to develop the replacements!"

      Why? Not being snarky, but why will the presence or absence of shuttle flights assist in the design, manufacture, and testing of a next-generation (yet equally superfluous) orbital vehicle? Obviously NASA will _use_ the shuttle, if only to justify its continuing existence, perhaps to fly parts up and let them undergo the shake, rattle, and roll of a launch, but what makes the shuttle a _necessary_ part of the design effort?

      I have made and continue to make a relatively unpopular statement. I'm not trolling or baiting or trying to be funny, but I feel strongly about this: De-orbit the ISS. Ground the shuttle fleet. Put all that money into the unmanned program and flood the solar system with rovers and parachuting probes and orbiting instrument platforms. They don't have to sleep a third of the time, they don't need air, or food, or water, or as much radiation shielding.

      We won't, though. The US as a whole has an enormous amount of national ego built into its status as a space-faring nation. It's like cities that don't feel "world class" without a professional sports franchise writ large. Never mind that we spend way too much, go nowhere, do little of value, and periodically kill everyone onboard.

      Perhaps things will change.

    NASA has a good record of recovering after a tragedy.

    If you take the Apollo program as an example, the very first Apollo mission was a disaster with three astronauts killed. And yet after that, the Apollo missions were great successes (although Apollo 13 was a close call, of course).

    The Hubble Space Telescope was launched with a faulty mirror, but this was fixed and Hubble's become a great success, too.

    The shuttle program will probably go the same way.
