Full disclosure: I may not know much about the space or desert at this time. I think an semi-automated system which generates space garbage which has a limited timeline to be salvaged by a space vessel before entering re-entry and landing in the desert.
Space Pirates & Corporate Pioneers could clash to retrieve it and anything missed would land in nearby city limits with its landing marked by a weather event where trackers could seek to find it first.
As to what this salvage offers - I'm not certain. I think that element would require a GM's touch.
