Space Shuttle to re-launch in May

Goeland86 writes "CNN reports that NASA is on it's way to prepare for a shuttle launch in may. Considering the damage caused by the Hurricanes this season, I think it's quite impressive that they're even thinking of a launch next year altogether."

      ""if" they are not doing anything innovative"

      I assure NASA's manned space program is doing nothing innovative to help the next breed of space capable crafts. NASA has set like 10 different dates for the Shuttle's return to service. The don't deserve praise for setting another one they probably wont deliver on. When they announced this date they couched it in all the same rhetoric about how aggressive it was and all the excuses for why they may not make it. The key thing about NASA's manned program, they get paid pretty much the same whether the do anything or not. They have no incentive to stick their necks out to be successful or innovative, they are just trying not to fail and preserve their budget. They have reached the point they aren't going to launch unless its "safe" and they are never going to make shuttle launches "safe".

      If you want a new manned space vehicle turn part of NASA's manned space program budget over to Burt Rutan in no strings attached grants. I'm willing to bet in a couple years you would have the next generation SpaceShipOne doing weekly runs to the ISS, for a fraction of the price of the Shuttle, and you would actually be able to fully man the ISS with seven or so people and actually do something up there instead of having 2-3 people who spend most of their time just maintaining it. If nothing else you could actually turn it in to the first space hotel and get people excited about space again, maybe charge the wealthy an arm a leg for a one week stay and let a few ordinary folks go for a week at $59 a night.

      If you had just given Rutan all the money NASA has spent doing nothing since the last accident you would probably soon have a whole new fleet of truly economical and reusable vehicles.

      If you want to restore your faith in manned space exploration look for the Discover Channel's multipart documentary on Rutan's successful run for the X Prize, "Black Sky: The Race For Space". They ran it in early October and I haven't seen a rerun. It is a great documentary, a great story and they look to be a great group of people doing amazing things on a shoestring and they clearly really care about what they are doing as opposed to the people at NASA.

      Burt does have concepts for a next generation ship to go in to orbit. If he had the money he just might make it happen.

      You need to be careful to not give Rutan to much money because you would risk turning them in to a completely corrupted oversized bureaucracy that doesn't do anything but spend money.

      No, we can't use technology to our advantage, as technology isn't the problem.

      The problem with the Shuttle is the same chicken-and-egg problem that space acess has faced for decades; With a small market and low flight rates, prices per flight rise. With high prices per flight, the market has no incentive to grow. This is Economics 101.

      It's also an issue of basic design; as Shuttle costs rose in the 1970's (partially because of development problems, partly because of inflation), NASA and Congress steadily made choices to trade reduced development costs for increased operational costs.

      I'll agree that Big Dumb Boosters only have limited applications. However, engines like SSMEs may have gone too far in the other direction. Part of the reason the shuttle is so expensive to maintain is due to those incredibly complex engines. It's kind of sad that few people ever seem to go for a compromise option - what is so crazy about the idea of part high-tech, part low-tech engines?

      Thanks for posting the articles about earlier NASA designs so more people could see them; many people seem to think that the shuttle today even resembles how it was designed before budget cuts. They really should move over to titanium for the frame. Its stats are just incredible. And while it's not the strongest superalloy (not even an alloy, but lets not go there) - for example, AerMet has over twice the tensile strength and is cheaper - Titanium is half the weight of most superalloys (AerMet, Inconel, Haynes, etc), has one of the highest melting points, and still remains quite strong (especially compared to aluminum alloys). A 15% craft mass savings translates to a *huge* benefit in terms of lightening design limitations (as well as the heat benefit allowing a less effective thermal protection to be used) and offers a great payload increase.

      Lowering the tech on your engines may cut your maintinance in half while costing you a few ISP; but building out of a better material (like titanium) will far more than make up for it. I'm a big supporter of "use the good, espensive alloys, but moderate your design complexity". I mean, using a cooled Haynes 230 nozzle (for example) with reasonable pressure, you'll get almost no relevant amount of corrosion despite repeated use. It's more of an up front cost, but so? We just need to give NASA the budget it needs for proper initial craft development.

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, be able to bring fairly large payloads (although not as large) from orbit back to earth.

    Too many times I've heard many people accuse NASA of not doing good quality management. At the same time, I've heard many people say that NASA costs too much - that they spend too much on everything. Sometimes, they're even the same people.

    Well, to be honest, these two issues are largely mutually exclusive. More testing costs more money. The reason that the shuttle is so expensive to launch, for example, is because they put it through such an extensive review (dismantling almost the entire SSMEs for inspection of parts, for example). One can say "Well, they should do (insert person's favorite test here) and omit (insert person's least favorite test here)". However, others among you will insist on just the opposite. Or both. Or neither.

    The people at NASA aren't Gods. They don't know in advance which tests will turn out to be important or not. They don't know in advance which sorts of inspections will be important. They have to make choices.

    You people can't have it both ways - you can either have more testing/inspection or less, corresponding to more cost or less. Fight amongst yourselves (quality pushers vs penny pinchers), and leave NASA out of it until you've made up your minds.

    While one certainly can say that for the Challenger disaster (there was pretty much a universal engineering consensus that they shouldn't launch, but political pressure due to budget cuts led to a launch anyways), you can't say that for the Columbia disaster. In fact, I'm only aware of a single engineer, out of the tens of thousands who have been involved on the Shuttle in some way or another, who raised the foam issue to NASA administrators. You'll probably get more criticism about the orbiter's toilet than that.

    Part of the problem was that not only does foam seem like it wouldn't do damage, but if you do the calculations, it doesn't pack very much force either, even at the speeds it was falling. The problem turned out to be its impulse. At those speeds, the foam behaved as if it were rigid, and so imparted all of its force to the RCC leading edge in a tiny fraction of a second. Few working on the project knew about this property of the foam, or even really suspected it.

    A more comprehensive testing suite could have caught this. However, NASA engineers aren't gods; they don't know in advance what will be the problem. To expand the testing suite would have made the project more expensive - and people are already complaining about shuttle costs.

    There's always that nasty balance between economics and safety.

    Mod parent up....

    I heard it straight from the horse's mouth. I attended two talks in the last week presented by Allan McDonald (although there were MANY engineers who initially called for the halting of Challenger, Allan was the head of these). The facts are:

    Allan and his company at the time, ATK Thiokol, had actually given the "no go" for launch due to many concerns... cold weather affecting o-rings, high wind shear forcasted, and the SRB retrieval team was leaving their post due to high sea swells. What did the management do? They called a midnight meeting between the engineering heads and the Mission Management Team. They then would not accept "no" as an answer, and finally got a "go" after an anonymous vote among Thiokol engineers (note: anonymous meant any one individual could not be blamed). Anyone see a major problem here? The bigwigs wanted to launch at all costs. Similar problems occurred right before Columbia.

    Face it people, NASA has become a "Prove that it fails or we will launch" rather than a "prove it will work or we won't launch" organization. Slight difference in wording, but huge gap in meaning.
