GTOP Database: Global Optimisation Trajectory Problems and Solutions

"TandEM-Atlas501" constrained

TandEM is an interplanetary trajectory with multiple fly-bys. The transcription proposed here uses one deep-space manouvre per leg, and a launch with the rocket Atlas 501, the performances being taken here.

Best Solutions

Here is a list of the best solutions known for different fly-by sequences. Note that E = Earth, V = Venus, M = Mars, J = Jupiter, S = Saturn
