Preliminary discussion cost per RLV

Rockets are every year more important in the context of Space exploration and Space transportation. One of the goal of these last decades a part the incrementation of the safety is the reduction of the price thanks to reusability. Reusability of the first stage of a launch vehicle using vertical landing techniques also presents the potential for further price per kilogram reductions. The combination of reusing the first stage of a small launch vehicle presented the most promising solution to reducing these prices. Due to the secrecy of the economic sphere in the aerospace sector the scope of this research is to estimate the cost for a reusable launch system thanks to the method explained in the Handbook of Cost Engineering. The data from estimation were compared to the data found on the internet thanks to a lot of tweets and interview released by Space X in order to understand if all the rumors circulating are true.
