NASA and Space Station Alliance On Shaky Ground

Posted by samzenpus on from the in-space-nobody-can-hear-you-disagree dept.

coondoggie writes "Even as the latest shift of astronauts arrived at the International Space Station, challenges with the orbital outpost on the ground are threatening its future. Those challenges include the pending retirement of the space shuttle but also the way NASA and the ISS are managed. A report issued this week by the Government Accountability Office said NASA faces several significant issues that may impede efforts to maximize utilization of all ISS research facilities."

  2. No human spaceflight can't help by jpmorgan · · Score: 4, Insightful

    Well now that Obama is going to cancel Ares 1, the USA won't have any human spaceflight capacity until probably the 2020s (assuming the rest of Constellation isn't canceled before then too). That can't be helpful for the future of the space station.

      Neither party has any interest in the future. One focuses resources on entitlements and the other on war.

      The existing Atlas and Delta-IV will be able to lift the Orion module just fine. Not only that, but Space-X's Falcon/Dragon vehicle will be ready well before then.

      Of course, NASA always has the option of building an alternative launch system for a lot less money than the ARES craft. The beauty is that all of the engines are already built and tested, and the J-130 can loft about 30-40 metric tons of payload (say, an MPLM along with the Orion module.

      jpmorgan, you need to keep up on the news, good and bad

      "Reporting on a White House and NASA meeting last Wednesday, sources say that the President has decided to give NASA an additional $US1 billion in 2011.

      Can't agree with tomhath either, looks like this administration is willing to invest in the future

      Unless you are a time traveler, that's an opinion - not a fact.

      Assuming, of course, that DIRECT doesn't behave like pretty much any other large scale aerospace engineering project and end up cost well above estimates while performing well below predictions.

      Correction. Both parties focus resources on entitlements and war.

      This is shameful. Better to be a beggar in a world colonizing the Moon, Mars, and mining asteroids, than to be a CEO in a world in which the human spirit is dead.

      Ares 1 was almost done.

      That will be why it wasn't supposed to make its first flight to ISS until around 2016.

      To put people on top of a Delta-IV or Atlas requires man-rating them.

      The whole concept of 'man-rating' is mostly nonsense: if a rocket isn't safe enough to launch some spam in a can, it's not safe enough to launch a billion-dollar satellite. There are issues with using the Delta and Atlas, but they're relatively minor compared to building a whole new launcher: ensuring that the trajectory used always allows a safe abort, improving engine-out performance (where your satellite is toast anyway so you might as well crash and burn on an unmanned launch), etc.

      If you want to start building Direct now, you have to consider all the work that's already gone into Ares in the cost. Is it still cheaper?

      Yes. Because you only have to build one new launcher and not two.

      One billion a year extra isn't going to get a heavy lift rocket ready in nine years.

      Note also that that extra billion is the lowest rate of growth of any budget item so far. Most of them are getting 9-12% increases, this is closer to 6%....

    Current estimates suggest they will lower the cost of cargo to the ISS from $46,000/kg to $20,000/kg. The Dragon capsule will serve as a lifeboat too, increasing the number of crew that can be permanently stationed at the station.

      I wonder if America is ready to tolerate a vehicle with a 33% success rate, which is what Falcon 1 has.

      If I remember correctly, Atlas had about a 75% failure rate before NASA stuck John Glenn on top, and I think the first Mercury/Atlas unmanned test flight exploded shortly after launch.

      Failures are expected during development, the question is whether you can fix the problems and move on (and sustain funding while you're debugging the system), which SpaceX appear to be doing.

  4. The first two points by CompressedAir · · Score: 3, Interesting

    The first two points in the article cancel each other out. To paraphrase, they are:

    1. It costs too much, so no one flies experiments, and
    2. There are too many experiments for the crew to handle.

    No one goes there anymore, it is too busy. -- Yogi Berra

    If the ISS is kept running for 5 years, we will get more out of the fifth year than we did the first year. If it is kept running 10 years, we will get more out of the 10th year than the 5th year. Launch cost will be dropping regardless of the fate of Ares, and as current research opens up new research the demand for space launch capabilities will increase. Remember, in the absolutely most boring future, the Russians could build a second Progress assembly line. The probable success of SpaceX just makes that better (notably in the "return of material" area.

    Now, is any of this worth it? That's more of a policy decision than a technical one. I think it is, half for the science and half for the global cooperation required. Remember, this International Space Station represents the efforts of 2/3 of the planet (land area-wise, heh, not population). When is the last time that has happened without there being a war in progress?
