NASA engineers worked with weavers to hand-thread copper wire through magnetic cores for the Apollo computer, encoding data by looping wire through rings for 1s and around them for 0s. One program took months to produce and mistakes meant unraveling everything, but the result was dense, radiation-proof memory that survived deep space.
Back in the 1960s, there was no memory chip that could be used in the Apollo missions, so NASA hired weavers to work alongside engineers. They created this core rope memory—copper wire that was looped around those tiny magnetic rings and could hold a surprisingly dense amount of information. The way it worked was pretty simple: through the ring equals to a 1, and around it equals to a 0. But because it was hardwired, it meant weaving a single program would take months. If you made a single error, you had to unravel it and start again. But on the flip side, because it was hardwired, it didn't crash, it couldn't get deleted, and most importantly, survived the radiation of deep space. That is why we have called this channel Core Memory, because we go inside the labs and factories with scientists and engineers who are building this crazy sci-fi future. Things like hypersonic planes, prosthetic arms that can read your thoughts, and flip people off. And one day we'll be this vault of how the future was made. So if you want to see how the future is built, follow along.
