In the 1960s, NASA’s engineers were building the Apollo spacecraft. But they ran into a
0:04
major problem that almost prevented them from getting to the moon. To solve it, they brought
0:08
in some unexpected help: expert weavers. The weaving experts helped get us to the
0:13
moon by enabling NASA to shrink the size of the Apollo Guidance computer so that it could
0:18
actually be launched into space. They did this by meticulously weaving the hardwired binary computer
0:23
memory by hand by passing a needle attached to a wire back and forth either through or around
0:29
the tiny rings in the core memory module; when they went through the ring, it encoded a one;
0:34
and when they went around, it encoded a zero. And despite their ingenious deployment of skill
0:39
and their critical role in the success of the moon landings, they were almost
0:44
completely ignored by NASA and the press as Americans celebrated the successful mission.
0:49
It wasn’t until very recently that at least some of the weavers were appropriately honored.
