NASA Ponders Postponing Launch until July 172

Posted by CowboyNeal from the wait-for-it dept.
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."

      • The LOX issue, however, is not likely related to this - this is about preventing ice formation on the LOX lines (they didn't state which ones), not the tank itself.

        Are the LOX lines vacuum insulated? Are they in proximity to other "stuff"?

        Sometimes fresh cryogenic eyes can spot problems. I am by no means an expert, but I've routed a few LOX lines (inside and outside cold boxes) and understand the design philosophy.

      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.

      • "Oh yeah, and without the shuttle, there's no Hubble."

        I don't think this is true. Using a robotic vehicle to carry out repairs is a serious option, and you don't need a shuttle for that, AFAIK. Just launch it up on a rocket.

      • It is highly possible that cargo-rated prototypes of a crew exploration vehicle could fulfill the United States' necessary obligations as far as the ISS is concerned.

        As for Hubble, naturally it is a rather controversial topic, but it seems to me you could send up a second Hubble with a longer initial lifespan for the cost of doing all the repair missions for the current one.
    • So your plan is to replace something which is in many ways the essence of pork-barrel politics (i.e. the source of tens of thousands of constituent jobs and local funding), and replace it with competitive enterprise (essentially the opposite of pork-barrel). Sure, that sounds great, but it's politically dead in the water.

      Don't get me wrong, I'm a big fan of things like the Centennial Challenges [nasa.gov]. However, there's a reason that Congress put a cap on how much NASA could spend on that program.

You don't dump 15,000 people on the street and expect them to be available in a few years when, or if, your new toy gets funded and built.
