A launch pad used for a rocket of some 30-35 MNewtons of thrust does not come out of it unscathed. It must be refurbished before it can be used again. How much does that cost? As an indication of such costs, specifically for a Saturn V launch system, how much did it cost to refurbish one of the Launch Complex 39 pads (including the LUT) after an Apollo launch? Answer can be in any-year dollars, but please specify which year. Or, if that information is too far in the past to be resurrected: how much does it cost to refurbish the pad after a Falcon Heavy launch?
