“…As for Mars transfer with electric propulsion, several works have been issued Coverstone 1997, 2000;Mark and Benton 2007;Bertrand et al 2001;Sankaran et al 2003;Miele et al 2005a,b;Circi 2004Circi , 2005. Typical thrust level T achievable by employing arcjets or Hall effect thrusters ranges between 0.1 and 10 N, with specific impulse I sp up to 10,000 s; laboratory tests showed that magnetoplasmadynamic thrusters can produce higher thrust values, up to 88 N (Sankaran et al 2003), but their functioning requires an unachievable power level.…”

Interplanetary transfers represent one of the most interesting themes of astrodynamics, because of its complexity and outcomes for human exploration of the Solar System. A wide number of works concerning different aspects of the interplanetary mission have been developed. The examination of these works leads to the conclusion that, by far, there is not a preferential propulsion system or an optimal trajectory to perform an interplanetary mission, but a precise kind of transfer according to a given mission profile. Here, minimum time trajectories to Mars for small payload transportation with different electric propulsion systems have been analyzed; results have been obtained considering the initial impulse given by the Ariane 5 upper stage. Additionally, an adaptative, multiple shooting optimization algorithm is proposed to solve the problem of optimality in interplanetary transfers with a low continuous thrust. The algorithm searches for the optimal set of initial Lagrange multipliers solving the two point problem by adapting the search intervals according to the unsmooth shape of the augmented cost function.
