Didn't they say these boosters had already flown before?
I'm also a bit surprised the grid find are so pricey, they seem pretty small? Not that I really know how much titanium costs to buy and machine.
- cryptoz 9y agoThe side boosters were flown before, and returned to Earth today for the second time. But they won't fly again.
- quasse 9y agoThey measure 4 by 5 feet, so we can estimate they are probably made from a solid chunk of titanium that was at least 20 cubic feet or almost 5,000 pounds. That would be nearly $150,000 in raw material and probably another 5x that in processing (guesstimating cost per cubic inch of titanium removal). Either that or they were specially made castings, which are similarly expensive in low volume, if not more.
- larkeith 9y agoWouldn't you be able to recover most of the removed titanium, amortizing the majority of that guesstimated materials cost? Processing likely remains expensive, however.
- solarkraft 9y agoI'd think so. They also 3D print a lot, but metal powder does seem expensive.
- cjsawyer 9y agoPrinted metal has huge issues with heat, and they just switched from aluminum gridfins to titanium because of the heat. I seriously doubt that they’re usung additive techniques here.
- stmfreak 9y agoYou are also dealing with low volume fabrication which means setup and tooling costs don't amortize across many components. I wouldn't be surprised if they cost $1M each.
