MANNED MARS MISSION. POSSIBLE WITH ADVANCED ELECTRIC PROPULSION?
Abstract

Mars is one of the most important middle- and long-term objectives for several national space agencies. Several unmanned missions had been carried out and manned missions are in everybody’s mind for the next projects. However, the state-of-art of the space technology seems not to be ready enough for this huge challenge: solar-proton emissions, cosmic rays, bone descalcification, heavy life support systems and crew psychological problems are only some of the problems whose risks increase with flight time. Decreasing the flight time is, therefore, a main objective.
Nowadays, different propulsion systems are being studied and the electric propulsion (like Hall thrusters) starts to be a viable option. Although its low thrust is preventing them to be used as a primary propulsion system, the development of high power electric propulsion systems and cluster systems opens new ways to Mars.
This paper shows the results of a study of High Power Hall thruster ability to put a payload in Mars in function of flight time, weights, electric power requirements and other important parameters. The High Power Hall Thruster performances are obtained from a 1D-model computer simulation and experimental results. An comparison with hall thrusters clusters is also done.

PD. Al final no hubo rugby, los otros no se presentaron por falta de gente. Lo que si hubo unas cervezas.
