Query: Interplanetary Transfers via Deep Representations of the Optimal Policy
  and/or of the Value Function   A number of applications to interplanetary trajectories have been recently
proposed based on deep networks. These approaches often rely on the
availability of a large number of optimal trajectories to learn from. In this
paper we introduce a new method to quickly create millions of optimal
spacecraft trajectories from a single nominal trajectory. Apart from the
generation of the nominal trajectory, no additional optimal control problems
need to be solved as all the trajectories, by construction, satisfy
Pontryagin's minimum principle and the relevant transversality conditions. We
then consider deep feed forward neural networks and benchmark three learning
methods on the created dataset: policy imitation, value function learning and
value function gradient learning. Our results are shown for the case of the
interplanetary trajectory optimization problem of reaching Venus orbit, with
the nominal trajectory starting from the Earth. We find that both policy
imitation and value function gradient learning are able to learn the optimal
state feedback, while in the case of value function learning the optimal policy
is not captured, only the final value of the optimal propellant mass is.
