Well I KNOW there is steel cable. I guess the spiral does give it some “give” when it comes to holding up tons of bridge steel. I’m thinking of something that might be useful for tying up stuff around a Martian camp site!
Although I guess with the big gloves they have to wear they won’t be tying any knots up there. I guess anything like that (say several cables to secure an antenna mast or a sensor) will require some sort of drill or hammer to place an anchor in the rock/”dirt” and then some wire cable and a crimping system.
It will be interesting to see how the helicopter thing works out. That looks pretty interesting and will sure aid them in their searches for interesting things to investigate.
