NASA Ponders Postponing Launch until July

BitFluid writes "According to Sun-Sentinel.com, NASA is considering postponing its Return to Flight shuttle launch because of 'ongoing concern about possible ice buildup on a liquid oxygen propellant line.' Apparently, that stuff turns into debris on launch, a risk they need time to investigate. If delayed, the target launch window becomes July 13 through July 31."

    Why don't you take the money you're spending on bandwidth and spend it again on charities that help third world countries? The moral position you're arguing in favor of would require it.

    Scientific research is a necessity to improve the quality of life for everyone on the planet. Human space flight is an important avenue for scientific research.

    By the way, for the record, the 2003 US budget for food aid was $2.5B; for the Shuttle, the budget was $3.1B.

      The Challenger was partially caused by ice and freezing. So the solution was to use insulation (basically a light-weight spray on that is similar to styrofoam). Sadly the Columbia was hit by the same insulation.

      Challenger's problem was with the O-rings sealing in the solid rocket boosters. They did not use foam to fix this.

      Columbia was damaged by foam that fell off the main fuel tank, which doesn't have any connection at all to Challenger's problem.

    Spray de-icer on it? Wrap it in an insulator? Blow warm dry air over it? Why can't there be a low tech solution to this?

      Spray de-icer on it?
      LOX has a boiling temperature of -183 degC, and the LOX line can be expected to be at approximately the same temperature. De-icer lowers the freezing temperature of water, but it doesn't lower it that much.
      Wrap it in an insulator?
      Any insulator would have to be flight-qualified with assurance that none could shed during ascent. If the insulation were to fall off, it could impact the shuttle and cause damage, or worse, allow ice formation.
      Blow warm dry air over it?
      This requires both a source of warm, dry air and the proper ducting to get it where it needs to be. This adds weight to the vehicle and has the potential to change the aerodynamics of the vehicle.

      The end result is that low-tech solutions can (and often do) result in additional complexities for the vehicle. I mean, it's not like we're dealing with the most complex machine ever built or anything...

      The Shuttle is the only vehicle capable of completing the International Space Station. If you stop flying the shuttle right now, the Space Station would be doomed. That's billions of dollars worth of hardware wasted.

      Don't care about ISS? Then what about other countries? America convinced Canada, Brazil, most of Europe, Japan and Russia to pool its resources and focus on building the space station. Pull out now, and you will NEVER be trusted again. Even if ISS isn't worth the price of the shuttle, pulling a multi-billion dollar fraud on the rest of the space-faring world will hurt America for decades to come.

      Oh yeah, and without the shuttle, there's no Hubble. Nasa's new administrator is still thinking about the pros and cons of sending a shuttle up to fix it.

      No, the mature thing to do is to hurry up and finish the space station, then drop the shuttle. Which is exactly what Nasa is planning.

    NASA did the job once, but since then they've done nothing but screw shit up.

    It's time for Congress to get off their asses and ACT. Jerry Pournelle came up with the idea, which would get us a complete spaceflight system in five years, and only cost 10 Billion Dollars.

    How?

    Congress must pass TWO lines of legislation.

    1) It is in the National Interest of the United States to have a mature spaceflight technology.

    2) The Tresurer of The United States is directed to pay, tax free, the sum of TEN BILLION DOLLARS to the first American Company to keep thirty Americans alive and well on the surface of the moon for Three Years and A Day.

    That's it folks. If we ain't got it, it's cause BUSH and Co don't want us to have it.

    ( Not that Klin-ton wanted us to have it, either, though... This idea ain't new. )

    All we lack is the will to achieve great things. Killing kids over lies, that we can do. "Supporting Our Troops", check.

    Pass TWO LINES of legislation to ensure AMERICANS have a stake in The Future? Nah...

    Well the issue is suddenly that people are concerned about the heat shield failing, yes? On the old rockets that went to the Moon, was it not that the heat shield was hidden almost until re-entry?

    It's a design flaw in the Shuttle, essentially. They're making sure that it's less likely happen again, over the course of the Shuttle's remaining years in service. Can you imagine what would happen if the next Shuttle were to suffer the same fate as the last? They're trying to get back to space using the only workable vehicle they have just now, so that the US is back in space, not waiting for a replacement. They might as well try to carry out this risky business in as safe a way as possible, and if that means delaying by another two months, so be it.

    Detection.

    This is like saying "cancer rates are up compared to 1965" ... I say "medicine is detecting more than in 1965".

    If you think the early flights were "safer" you're most likely sadly mistaken. They just didn't know about all the problems that could go wrong or had ways of addressing them.

    Keep in mind the driving force was to beat the ruskies to the moon. So at all costs.

    Though I agree. The shuttles are outdated and there are likely cheaper/safer ways to accomplish the same goal using technology ... from THIS DECADE!

    Come on, think of the big picture here. I know being simplistic and small-minded is the catch-phrase of our "new generation". But what if they said this 40 years ago? Why even go to space? Look at all of the technologies we have developed whilst trying to get there. We would not be able to live without half of these advances! (Especially the freeze dried food).

    More importantly, compare $3.1B against:
    (a) amount spent on pizzas in the US
    (b) amount spent on election campaigns
    (c) amount paid to actors for acting?

    If you are going to be fair, then be fair. Talk about it being a capitalist world, and that we only give money for food at all because we are:
    (a) making ourselves look better on the world stage
    (b) appeasing that guilty little bit of ourselves
