Dataset Summary

The Titan-Hohmann-Transfer-Orbit dataset simulates an interplanetary mission to Titan using advanced propulsion systems and gravitational assist techniques. This synthetic dataset is designed to review:

• Trajectory optimization algorithms
• Electric propulsion system modeling
• Mission risk assessment
• Machine learning training for aerospace and trajectory decision-support systems.

Mission Profile

1. Earth Departure: The spaceprobe begins its journey with a launch vehicle, departing Earth’s orbit and entering a heliocentric transfer trajectory.
2. Gravity Assist Phase: The spaceprobe utilizes planetary flybys (e.g., Jupiter) to optimize its trajectory toward Saturn and Titan.
3. Heliocentric Cruise: The spaceprobe completes extended low-thrust propulsion arcs using Hall Effect thrusters, further refining its trajectory.
4. Titan Arrival: Final adjustments are being made for the space probe's orbital insertion, initiating Part Two of the mission profile. This phase includes the Entry, Descent, and Landing (EDL) of floating probes to study Kraken Mare, Titan's largest methane sea, along with the EDL of a communication relay near Kraken Mare to enable efficient data transmission between the floating probes and Earth.

Columns (Relevant for Model Training)

1. Initial_Total_Mass

   • Total spaceprobe mass (kg) at the mission start, including fuel and payload.

2. Dry_Mass

3. Thrust_Level

   • Thrust output of the Hall Effect thrusters (mN).

4. Launch_Vehicle

   • Categorical data specifying the type of launch vehicle used (e.g., “Falcon Heavy,” “SLS”).

5. Mission_Segment

   • Categorical description of the mission phase (e.g., “Launch,” “Cruise,” “Gravity Assist,” “Titan Arrival”).

6. Time_of_Flight_days

   • Elapsed time from mission start, measured in days.

7. Orbital_Radius_km

   • Radial distance from the central celestial body (e.g., Earth, Sun, or Titan).

8. Semi_Major_Axis_km

   • Semi-major axis of the spaceprobe’s elliptical trajectory (km).

9. Eccentricity

   • Describes the shape of the orbit (0 = circle, <1 = ellipse).

10. Inclination_deg

    • Orbital plane tilt relative to the ecliptic or other reference plane.

11. True_Anomaly_deg

    • Position of the spaceprobe along its orbital path.

12. DeltaV_Used_km_s

    • Total accumulated ∆v (km/s) expended since mission start.

13. Thrust_Events_Start_Time

    • Timestamp indicating the start of a thrust event.

14. Thrust_Events_Stop_Time

    • Timestamp indicating the end of a thrust event.

15. Closest_Approach_Distance_km

    • Distance at closest approach during gravity-assist flybys.

16. Relative_Velocity_km_s

    • Velocity of the spaceprobe relative to the flyby planet or Titan upon approach.

17. Final_Orbit_SMA_km

    • Semi-major axis of the final orbit around Titan (km).

18. Final_Orbit_Inclination_deg

    • Inclination of the spaceprobe’s orbit around Titan after insertion.
