How come? If the idea is to be capable of inspecting the tire, then puncturing it if it's deemed a time bomb, why wouldn't this do the same?

- mtreis86 3y agoThe tire is risky in the first place because people are around, making shooting a gun off a bit tricky in terms of safety.
- maxlin 3y agoA gun is not a bomb. It is a reasonably precise tool. If the point is to puncture a wheel, and there is one guy at NASA who isn't bloody blind, I really don't see how this becomes less safe from the tire exploding anyway.
- MadnessASAP 3y agoI'm sure that there exists a real reason, but I choose to believe that it's because NASA is made of engineers, and engineers are by nature not practical people. They want to design a solution, not find a solution. If they'd asked the technicians then they would've landed on Steve with his target rifle, or just a plate with a few spikes in it to drive the wheel over. Y'know, simple, straightforward, and absolutely no drawings required.
- maxlin 3y agoMight be true lol. NIH (Not Invented Here) syndrome with the first part of "if it's not even invention, it's a worthless solution"
- klyrs 3y agoNIH doesn't describe this. They bought a model tank from a hobby shop and strapped a drill to it. For an organization plagued by accusations of excessive costs, this is downright cheap. NIH would involve a purpose-built rover to the tune of millions of dollars.
- neuralRiot 3y agoIf you read the article you’ll find that the device successfully punctured many tires WITHOUT any explosion.
- ImPostingOnHN 3y agoThe point isn't to puncture the wheel, it's to measure the exact failure modes. They know if they puncture the wheel, it will burst. A drill, for example, tells you the characteristics of exactly when and how it will lose structural integrity given a partial puncture of a given diameter and depth.
