I assume you meant rockets in your first sentence, as most satellites (other than spacecraft) don't survive landing :) SpaceX/Elon hasn't gone into a huge amount of detail about what's involved in refurbishing the first stage. I imagine a lot of it comes down to inspecting parts and making sure they haven't been damaged or worn out, and replacing the ones that have. Maybe cleaning out soot from the engines. The stated goal is to not have to do any inspection or refurbishment between flights, but they aren't there yet. https://twitter.com/elonmusk/status/1143195449425321984 https://twitter.com/elonmusk/status/1143195449425321984 https://twitter.com/elonmusk/status/1313450351366873090 https://twitter.com/elonmusk/status/1313450351366873090
