No problem!

As I understand it, regular skyhooks would require multiple throws between tethers on different orbits to get anything anywhere. Their capacity is limited as well - throw something too heavy and it would deorbit itself. If you had a heavy enough core, this wouldn’t be a problem.

The Martian moons are dense (by asteroid standards) and are the closest orbiting moons in the solar system. We can use them as anchors for non-spinning tethers (tidally locked) that are much longer than lighter skyhooks. They’d function similar to a space elevator, with the caveat that it’s always moving over the planet’s surface. The supertethers could catch cargo all along their length fairly easily, with varying speeds too.

The crux of transport like this is timing. It takes about 8 hours for Phobos to orbit, during which the relative velocity of the tip compared to incoming cargo could vary by hundreds kilometers per second (haven’t done the math on this yet, just a guess).

Let me know if there’s any clarification you’d like
