Mission analysis of human Mars exploration based on Space Elevator

Based on the conical curve algorithm and Lambert algorithm, use assistant graph algorithm to calculate interstellar transfer orbit and understand the Earth-Mars transfer orbit mission windows. The calculated result shows that there is one launch time on the Earth-Mars transfer orbit every 2.1 years. In every 15 years, there must be a pair of launch times which are almost same. So based on the DRA5.0 nuclear energy project for Manned Space of Mars, introduce a new Mars explored mission based on the Earth Space Elevation. The result shows that the aero-craft's velocity will reduce 2.4 km/s based on the space elevation when it is launched from the earth, the freighted aero-craft's size will decrease 19% and the manned aero-craft's size will decrease 26.9%.
