The team behind Nasa’s Osiris-REx mission is struggling to open fully the container holding the bulk of the sample from asteroid Bennu. Since the 4.5 billion year-old sample landed in the Utah desert earlier this month, scientists have already managed to collect 70.3 grams of rocks and dust lying on the outside of the container, …

    But they designed the container… they decided the environment to open it in… why haven’t they already tried and certified the tools needed to open it? Wasn’t that thought of in advance? Or is this just a case of, these tools should work, but for some reason failed? Which is what i’m assuming, since only 2 of the 35 can’t be removed, but still.

      The article linked here is kind of crappy. It’s just a single fact stretched out into a couple of paragraphs with no context. Take a look at these real articles, they show the confined space the scientists and engineers are working in, and why it’s so important to take their time doing things right.

      If this was just a regular box, you spray some penetrating oil on it, or you can heat it, or you can crank on the bolt until it breaks, then drill out the remaining parts. But all of those options can ruin the sample inside.

      This is a box with unique material, they have one chance to open it, and there is no time limit on opening the box. So they’re going to sit down and do some math and figure out the best way to open the box without ruining the contents. They’ll get it open, they just really really don’t want to fuck it up, cause they don’t get a second try at it.
