NASA Plans Three More Shuttle Flights This Year 167

Posted by samzenpus from the dare-to-dream dept.
Lonesome Squash writes "The BBC are reporting that a new fuel tank is due to arrive on Wednesday that fixes the well-known problems with insulation loss. According to the article, administrators are hopeful that they will be able to "squeeze in three launches" this year. I guess they've lowered the bar enough that even the Shuttle program can slither over it. I can only be grateful that I'm not the poor chump who has to write their press releases."

    NASA Plans To Push Back Three More Shuttle Flights This Year To Next Year
    • A NASA spokesperson nervously announced more shuttle flights this year. Then a reporter accidently dropped a penny on the ground, and the NASA spokes person dove for cover, and announced "nevermind, no more shuttle flights for another year!"
    • There was an editorial on SpaceDaily recently which presented an interesting perspective: that Griffin is trying to kill the shuttle program. Griffin was on the record as explaining that the cause is due to a fundamental problem with side-mount craft on tanks with cryogenic fuels: the tank's size changes as the temperature changes, causing tiny cracks that allow gas to get inside. The gas liquifies, then reexpands in the upper atmosphere and blows off foam.

      Yet, they're still launching, without a fix. The

        Saturn V baby. I've been criticized for saying it before, but I find it interesting that the CEV is now looking at J-2s instead of SSMEs modified for in-flight start. The F-1 is still one of the most powerful on the books. To this day, I don't understand why the US space program didn't stick with what worked. Sure, SSMEs share a common ancestory with J-2, and the OMS is a derivative of the SPS, but what ever happened to the old RP-

    • Is that really a good idea?

      They only have 3 to spare:

      Well, they only promised launches, not landings. Three launches, three shuttles. Sounds like a good fit to me.
    • Griffin and the shuttle program manager have both been very emphatic that further launches will not happen if they don't believe the work done since the last launch has appreciably reduced the risks, which are already low. "They only have 3 to spare" is irrelevant in asking whether or not to launch unless you don't have a good idea what is going to happen.

      Just for kicks, I'll flog the dead horse one more time and look briefly at the numbers. The shuttle has flown 114 (?) times and had two catastrophic fa

    It's still an impressive technology, re-useability has a great appeal,

    with more conventional rocket launches?
    • For added effect, I vote to load each shuttle up with platinum bars, a Ming vass collection, paintings by Rembrandt and Picasso, and many millions in $100 bills.
    • Shuttle costs are weird. AFAIK, it's the most expensive launch vehicle (no matter how it's measured). Most of these are fixed costs, though. (standing army of matinence people, whether or not the shuttle flys and the like) It's not all that much more expensive to do 12 flights per year, than 0. Admittedly, 12 flights per year is nigh impossible with the system...
    • What convential rockets? If we had conventional rockets capable of lifting cargo to the space station, don't you think we'd be using them? Instead we have to essentially buy progress and soyuz launches (at least any outside of the flights specified in our existing agreements, which I believe we have already reached the end of).

      That's why it is so urgent to get the newer unmanned cargo lifter system (and the crew exploration vehicle or whatever they call it) operational as soon as possible. I think the de

        Thus the last hope that the shuttle program would develop any useful technology what-so-ever is lost.

        • What do you mean 'upgraded' apollo engines? Do you realize that one Saturn F-1 engine produces more thrust than all 3 SSME's on a Shuttle Launch ? 1... and the first stage had 5 of the damn things. 1.5 million pounds of thrust each compared to Shuttles ~1.2 for the combined thrust from 3 SSME's.
          • Not F-1s.
            They are planning on using J-2s for the CEV second stage. They are not Apollo engines anyway they where both Saturn engines. The J-2 was used for the second and third stage of the Saturn V and for the second stage of the Saturn 1b. Nasa managed to keep some development money going to the J-2 all these years. They have tested an aerospike version and the liner aerospike that the X-33 was going to use was based on it. The J-2 also has an in flight restart capability that the SSME currently lacks.

            • Yeah I did know about the current itteration of the J-2 being used, just wondering what the original poster was after as they didn't really specify and I like reminding folks just what we gave up on with the F-1. Also thought the concept of saying we were 'going back' to it was kinda silly. As you pointed out it is an engine that has been in constant development for the last 30 years or so.

        • Mmmm, I dunno. Don't you think they learned something from designing and running the SSME for twenty-odd years? Or something about good heat-shield design by landing the orbiter 100 times successfully and once unsuccessfully?

          In science and engineering, even a failed experiment is progress. If nothing else you learn what not to do next time, but far more often the data you collect when things don't go the way you expect them to is highly useful for the next try. It may be that the Shuttle is not the righ

      The Shuttle is more expensive that current expendable yes - but then platinum is more expensive than gold too. (I.E. current expenables are too expensive by a large margin.)

Well, if the shuttle is still going up, we could maybe use it for something like servicing the Hubble space telescope and extending its life! You know, since it's still at the forefront taking cutting edge pictures like the wonderful mosaic of M101, which is

      Personally, I'd rather see them finding out how cats adapt to zero G. They're semi-aboreal, good climbers and, with the right wall covering, can hold on and walk around using their claws for traction, just like in a tree. Also, they're smart enough to experiment, find out what works an learn how to get around.

    Space exploration has been dangerous for half a century, but has been rewarding for the advancement of science and technology. Neither fact is going to change in the next half century.

The main tank is totally encapsulated in super glue.

  • NASA launched so much new technology, it's sad that a program that brought so much is consistently underfunded. Imagine the possibilities in innovation if adequate resources and minds were still placed behind the program. The "Jetson's" car would have been a reality by now. Instead you now see private investors pushing the innovation in space exploration, such as paypal founder.

There are all kinds of ppl who do large projects successfully; Griffin is one of those. He can make this happen. Of course, there are other types of ppl who manage large projects; O'Keefe, Brown, johnson, Nixon, and Bush come to mind for those.

    Exploration always results in new and unexpected advances in science. We explored all the land, were working hard on the oceans, and as soon as we can we should explore as far as we can reach from our planet.

    I applaud NASA for doing their best with their limited budget, a reusable ship based on technology that has been successful in the past is exactly what they should be doing. They have a bad track record, they need to do a few safe missions to gain public support.

    Its just too bad for them (although I couldnt be happier) that the private companies are going to steal the show.

  • No, seriously, think about exploration for a bit.

    In the past, we've had explorers sailing off for possible one-way trips, running out of food, dealing with canibal tribes, disease, etc.

    In the past, we had wars fought up close and personal with knives, axes, swords, etc, not by remote control.

  • The two biggest constraints for timing the next shuttle launches are
    (1) it must be launched in mid-daylight so the large array of cameras can capture every angle of launch and
    (2) it has to go into a highly inclined orbit to catch up with the space station.
    Both these only allow three two week launch windows for 2006. The constraints will be relaxed a little if the next two launches are 99.9% successful, else they will continue.
