# Mission Design and Trajectory Skill

## Purpose
Enable comprehensive space mission design and trajectory analysis including orbital mechanics, launch window optimization, and maneuver planning.

## Capabilities
- Orbital mechanics calculations
- Launch window analysis
- Delta-V budgeting and optimization
- Transfer trajectory design
- Maneuver planning and sequencing
- Rendezvous and proximity operations
- Entry, descent, and landing analysis
- STK and GMAT integration

## Usage Guidelines
- Define clear mission objectives and constraints
- Optimize trajectories for propellant mass or time of flight
- Consider launch vehicle performance and constraints
- Account for perturbations in trajectory propagation
- Plan contingency maneuvers for off-nominal conditions
- Document trajectory design assumptions and margins

## Dependencies
- STK (Systems Tool Kit)
- GMAT
- MATLAB Aerospace Toolbox

## Process Integration
