The Curiosity MARS rover may represent some of humanity's most recent technological achievements, but it couldn't be possible without some of the earliest. That's the takeaway from an in-depth post over at the International Guild of Knot Tyers Forum, which details the various knots NASA engineers employed to keep Curiosity together. The author claims that knots are still used for cable lacing both because of their efficacy and the "conservative nature of aerospace design," which sees no need to discard proven technologies for the sake of it.
