## **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 made to insert the spaceprobe into orbit around Titan for mission operations.

## **Columns (Relevant for Foundation Model Training)**

1. **Initial_Total_Mass**  
   - Total spaceprobe mass (kg) at the mission start, including fuel and payload.

2. **Dry_Mass**  
   - Spaceprobe mass without propellant (kg), useful for estimating burn times and fuel efficiency.

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.

## **Intended Usage**

- **Foundation Model Training**: Suitable for time-series and tabular data modeling in the context of interplanetary trajectories.
- **Synthetic Orbital Analysis**: For exploring gravity assists, electric propulsion, and mission design principles.
