The concept of Vertical landing Rockets was developed to achieve re-usability of the rocket in order to decrease cost and time of Rocket launching. Successful attempts of vertical landing rockets have been attempted by SpaceX and Blue origin with the motivation of reduction of manufacturing and research costs, these have led the path for the re-usability of rocket engines and autonomous recovery of rockets. This paper will discuss the challenges to meet the precision landing of rockets on earth and other planets and also factors required to extend this technology to implement it in future space tourism.
