We consider the interplanetary trajectory design problem posed by the 8thedition of the Global Trajectory Optimization Competition and present theend-to-end strategy developed by the team ACT-ISAS (a collaboration between theEuropean Space Agency's Advanced Concepts Team and JAXA's Institute of Spaceand Astronautical Science). The resulting interplanetary trajectory won 1stplace in the competition, achieving a final mission value of $J=146.33$ [Mkm].Several new algorithms were developed in this context but have an interest thatgo beyond the particular problem considered, thus, they are discussed in somedetail. These include the Moon-targeting technique, allowing one to target aMoon encounter from a low Earth orbit; the 1-$k$ and 2-$k$ fly-by targetingtechniques, enabling one to design resonant fly-bys while ensuring a targetedfuture formation plane% is acquired at some point after the manoeuvre ; thedistributed low-thrust targeting technique, admitting one to control thespacecraft formation plane at 1,000,000 [km]; and the low-thrust optimizationtechnique, permitting one to enforce the formation plane's orientations as pathconstraints.
