[...] Combined, the loss of NASA's Orbiting Carbon Observatory and Glory satellites cost the space agency $700 million. In the years since, the space agency's Launch Services Program and the rocket's manufacturer, Orbital Sciences—which has since been acquired by Northrop Grumman—have been conducting investigations into what happened.

[...] But only now has the story emerged in greater detail. This week, NASA posted a summary of its decade-long investigation into the mission failures. Long story short: faulty aluminum extrusions used in the mechanism by which the payload separates from the rocket, known as a frangible joint, prevented the separation from fully occurring. Much of the report drills down into the process by which NASA reached and then substantiated this conclusion.

    The idea of an engineered frangible joint in something as demanding as a payload separator is... ambitious from the start. From the summary, it sounds like it didn't break easily enough - but that's certainly no worse than breaking too easily, and these aren't the kinds of parts you can test functionality of before use.

    Maybe if budgets weren't squeezed to the limit, they could have manufactured a series of 20 joints, and tested every other one, and if they were all within tolerance then selected the joint in-between the two best performers to send on the actual launch. But, that would look wasteful to someone... in need of a more efficient approach, like taking a risk of total mission failure on a $700M mission.

      So why would you ask for things from manufacturers that are without specs and then they lie? Might as well just order shit on ebay and do all your own testing because no one can do their jobs..

        Never said any such thing.

        I will say that "human factors" are a reliable confound of reproducability, and that's why you need to do more than make one of something and declare: "it is infallible because: science."

        Bean counters have a magical thinking that believes increasing risk by a tiny, invisible to them, fraction on a large thing is an acceptable risk when saving a few easily demonstrated pennies.

          And TFA is even more precise on the causes and what more one should have done:

          And in 2015, the company that supplied aluminum extrusions for the four-stage, solid-rocket Taurus XL booster, Sapa Profiles Inc. (SPI), admitted that it had falsified quality control test results for its products.
          ...
          The investigation found that SPI had falsified records about the materials used in its extrusions for about a decade. Internal, handwritten accounts of SPI's material properties tests revealed that the company made alterations to more than 2,000 test results between about 1996 and 2006, affecting more than 200 customers.

      20 tests is a drop in the bucket on that budget. They could do 20,000 tests without budgetary strain.

      I think the real problem was that mission failure just wasn't important. It shouldn't be, but only because they should have several more dual missions on that budget not because most of the funding goes into making stuff rather than doing stuff.

      Outright falsification of documents isn't justified no matter how constrained a budget might be. Falsifying documents has a name: FRAUD. An individual or a corporation can get away with a lot of shit, so long as they don't falsify the documentation. I learned that early in life, as a young seaman. "Whatever you do, Seaman Runaway, DO NOT gundeck the logs! If you don't get the inspections done, LOG IT THAT WAY!! You may get some extra duty, if you fail to complete all the inspections you are responsible for, but you will GO TO PRISON if you gundeck the logs!"

      I would have said: Maybe if they hadn't falsified their results on something that could lead to hundreds of millions of dollars of loss . . . .

      From TFA

      It might be easy to blame on a budget problem, but this falsification went on for a decade. It wasn't a one time thing. It was more like a competitive cost cutting weapon on bidding. In 1996 to 2006 this kind of thing is something I would only have expected from Microsoft.

            According to my 1st grade class (in 1972) most definitely. 50% of us wanted to be Astronauts, there were scattered firefighters and policemen, but enough girls wanted to be Astronauts to bring us up to 50%. Not a single 1st grader even thought about wanting to be a soldier, and this was the population whose parents were on the hook for the draft in Vietnam.

            Sure, except that the legislature lost their appetite for Apollo after 13, couldn't risk looking bad, so they played out the missions that were already sunk costs and trotted out the old depression era nugget: "we just don't have the money, honey..." and their constituencies ate it up.

            We get the government we deserve. And, it will be a long, long time before government regulation / subsidies aren't the make/break factor in space industries' success, whether as government contractors, competitive entities sponsored by other nation-states, or so-called independent businessmen.

    The real reason for the failure is that it takes NASA a decade to find why a mission failed and then they don't point towards the guilty parties. I guarantee you if contractors and staff engineers knew post-failure investigation involve freezing all missions until a cause is found and that a typical investigation lasts a few months and concludes with a public hanging, you wouldn't have half-assed, single-point of failures designs just because someone made a patent for a new type of joint.
