Dataset Summary

This dataset contains a comprehensive set of synthetic data for an interplanetary mission to 624 Hektor, modeled using a Type II Hohmann transfer orbit. It features:

• LEO Departure and heliocentric trajectory phases.
• Jupiter gravity assist flyby.
• Electric propulsion thrust arcs.
• Final insertion at 624 Hektor on March 18, 2032.

The dataset is ideal for machine learning tasks related to orbital mechanics, low-thrust mission optimization, and multi-body transfer simulation.

Mission Profile

1. LEO Departure: Initial departure from Earth's orbit using electric propulsion.
2. Heliocentric Transfer: Transitioning into an interplanetary trajectory.
3. Jupiter Gravity Assist: Utilizing Jupiter’s gravity for a velocity boost.
4. Arrival at 624 Hektor: Final insertion burn at the target asteroid.

Final Event: March 18, 2032, orbit capture at 624 Hektor.
