What is it about?
The 12th edition of the Global Trajectory Optimization Competition (GTOC 12) presented a complex problem targeting the mining of materials from many different asteroids. This work presents the solution approach of the team 'TheAntipodes', which came fifth in the competition with a solution consisting of 27 ships. A combination of beam search and sequential convex programming is used to tackle combinatorial and trajectory optimization parts successively.

Why is it important?
Our findings present a relatively unique solution approach to the GTOC 12 problem. For example, most other teams utilized indirect optimization approaches in comparison to the direct sequential convex programming method that is presented in this work.
Perspectives
The collaboration between many individuals and the friendly competition of GTOC were excellent experiences and have in the past led to many developments within the astrodynamics community. Writing this article was a great perspective in order to understand just how is done by all teams within the month-long competition.
