Re: It’s ok we’ve done it before.
"I was thinking it might have been slightly safer to break them up into their component cells (or at least smaller clusters) and then propel them slightly so they reached the atmosphere sooner. It's only a couple of hundred km to the atmosphere, after all."
They're already touching enough atmosphere to experience drag (the only have something like 400km to the surface) . Smaller clusters would be harder to track (and may decay slower, idk). Breaking them down is a nontrivial task, especially in orbit, especially if the pack was not explicitly designed for disassembly.
