It’s a good point: I’d assumed that the plan was to make the payload of basically the same material as the tether/structure, and have it destructively tear-off at the right moment (maybe by having a watching supervisor structure lasering a weak point)

But I think pouching the payload (presumably forming the structure around the payload) just translates the problem into holding a 8kg steel block to the ceiling with 1cm square of paper formed into a harness, and expecting it to hold for weeks.

Either way - hopefully it will be addressed in a follow-up
