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

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

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

Dataset Columns

Key Orbital Mechanics Parameters:
