- Abstract
Europe is investigating the next version of ATV with re-entry Cargo capability with the option of a man rated version as crew transport vehicle. In addition exploration missions to Moon and Mars are planned. The current propulsion systems are using long term storage toxic propellants and therefore special safety measures are needed to safeguard the humans staying on board of the ISS. ASTRIUM Space Transportation and DLR initiated a working group to investigate the possibility to exchange the storable but toxic propellants by more green candidates for both future ATV and Moon / Mars Lander. This paper gives an overview of the study logic, the objectives of investigation by the industrial partner ASTRIUM and the DLR institute to indicate the most promising non- and/or low toxic candidates. The investigations are based on mission profiles for the ATV - future missions as well as for soft landing application with throttle capability of beak-engines. A technology road map is recommended with the focus on performance potential, material compatibility, long term storage capability and throttle capability of the engines for e.g. soft landing application in the 400 N / 2500 N engine class thrust range.
