Visualization of a spacecraft trajectory for a mission of exploration to 17 asteroids flying in the vicinity of Earth's orbit.
The Earth is seen here in blue, and the spacecraft as a red cross. A trail remains behind the spacecraft, showing it's path over the preceding year. White portions of this trail correspond to rendezvous legs (spacecraft is flying towards a new asteroid), and red ones to self-fly-by legs (spacecraft is flying in the asteroid's vicinity, to launch a "penetrator" towards it). The dotted lines on the plots correspond to the Earth's values: a distance of 1 AU to the Sun, and 0 degrees declination, respectively.
This trajectory constitutes a Lambert model solution to the trajectory design problem defined in GTOC5, the 5th edition of the Global Trajectory Optimization Competition. It was assembled in the research project described in the paper:
