You need to dig (pun intended) into the subject a bit more. The subduction zone of a tectonic plate might be 50 kilometers down, not 50 meters. People have suggested putting nuclear waste in some of the deeper ocean trenches formed by subduction zones where the plate boundary is thin ( 1 - 10 km). Problem is it would take tens of thousands of years for the material to subduct appreciably below the surface. In the meantime it would be actively falling apart just like everything else in a marine environment. Then there is the small issue of getting the stuff down to a particular point a kilometer or so below the surface.

Go look up Project Moho for the difficulties in getting stuff down to subduction zone.

I know this is all retro and stuff, but land lines aren't dangerous or particularly expensive. Mine comes with my Internet connection, YMMV.

And, although emergencies are fortunately rather rare, I would prefer to depend on my land line than my AT&T-we-might-complete-this-call-if-we're-having-a-good-day cell phone.

Slight correction. The reason the de Haviland Comet's fuselage failed was because of the square windows concentrating stressors at the corners created a series of weak areas all along the fuselage. You will notice that any aluminum aircraft or boat has somewhat rounded corners on windows.

Take that Apple!

Curiosity does have a bunch of 'nylon tie' like objects on the top of the rover, holding bundles of cables together. Wonder what they're made out of. A quick search found lots of documentation on exactly how to run the cables (fun factoid - they still use knots on cord) but not much on what the stuff was made out of.

No, what this actually says is that mission goals of a specific time are a nebulous, silly concept that are foisted off on the Power Point People because it's simpler than explaining complex physics and material sciences. It avoids icky concepts like engineering trade offs, probabilities, risk ratios and mathematical feats more complicated than 'next slide'.

If you have to ask how much it is, you can't afford it.
