T1  - Interplanetary trajectory optimization for a sep mission to Saturn
T2  - 60th International Astronautical Congress 2009
N2  - The recently proposed NASA and ESA missions to Saturn and Jupiter pose difficult tasks to mission designers because chemical propulsion scenarios are not capable of transferring heavy spacecraft into the outer solar system without the use of gravity assists. Thus our developed mission scenario based on the joint NASA/ESA Titan Saturn System Mission baselines solar electric propulsion to improve mission flexibility and transfer time. For the calculation of near-globally optimal low-thrust trajectories, we have used a method called Evolutionary Neurocontrol, which is implemented in the low-thrust trajectory optimization software InTrance. The studied solar electric propulsion scenario covers trajectory optimization of the interplanetary transfer including variations of the spacecraft's thrust level, the thrust unit's specific impulse and the solar power generator power level. Additionally developed software extensions enabled trajectory optimization with launcher-provided hyperbolic excess energy, a complex solar power generator model and a variable specific impulse ion engine model. For the investigated mission scenario, Evolutionary Neurocontrol yields good optimization results, which also hold valid for the more elaborate spacecraft models. Compared to Cassini/Huygens, the best found solutions have faster transfer times and a higher mission flexibility in general.

N2  - In Anbetracht des zu erwartenden Rückgangs der Verfügbarkeit fossiler Rohstoffe müssen nicht nur für den Energiesektor, sondern auch für die Herstellung industrieller Produkte alternative Rohstoffe gefunden werden. Ein Beispiel für einen nicht in Nahrungsmittelkonkurrenz stehenden nachwachsenden Rohstoff ist grüne Biomasse wie Gras und Klee. Diese lassen sich in Deutschland auf großen Flächen anbauen und enthalten eine Vielzahl potenzieller Substrate für Fermentationen.
