Learn how to use gravitational assists (slingshots) in Kerbal Space Program to conserve fuel and achieve complex interplanetary maneuvers. Essential for efficient space exploration.

The Kerbal Space Program Wiki is a comprehensive, unofficial guide to Squad's space flight simulator. This section focuses on a specific advanced maneuver: Gravitational Assists, also known as slingshots.

Walkthrough
  1. 1
    Understand the concept: A gravitational assist uses the gravity of a celestial body (like a planet or moon) to alter a spacecraft's speed and/or direction without expending fuel.
  2. 2
    Identify target celestial bodies: Planets and moons with significant gravity, such as Kerbin, Mun, Duna, and Jool, are ideal for slingshot maneuvers.
  3. 3
    Plan your trajectory: Use the map view to plot a course that will bring your spacecraft close to the gravitational body. The closer the approach, the greater the effect.
  4. 4
    Execute the maneuver: When your spacecraft is in the optimal position, perform a burn to adjust your trajectory. The gravitational pull of the celestial body will then modify your orbit as intended.
  5. 5
    Observe the results: After the encounter, check your new orbital parameters to confirm the desired speed and direction change.
Tips
  • Gravitational assists are crucial for long-distance interplanetary missions, significantly reducing the fuel required.
  • Timing and precise trajectory planning are key to successful slingshots.
  • Be aware of the gravitational body's own orbital path to ensure a predictable outcome.
  • Multiple slingshots can be chained together for complex mission profiles.
