The Landing Leg is a part used to prevent rockets from landing on their engines and other parts, as they will break on impact if the rocket's velocity exceeds 5 m/s. As a spacecraft without an engine inside an atmosphere is virtually useless, this is a good way to protect the engines and other parts from being damaged. The legs are usually placed in pair to increase stability after landing and prevent the craft from tipping over. A landing leg can withstand impact speeds up to about 12 m/s.

In Version 1.5, a larger version of the leg was introduced which now overcomes the issue of needing to add structural parts to extend the legs.

As they can be extended and retracted on click, they are a popular part used by engineers to develop new game mechanics. Landing legs can be used for hangar doors, mechanical arms and many more fantastic creations.

Note: Not all parts are as flat as the launch pad. Thus, landing legs should never be placed too far apart, or else debris on the ground or small dents on the surface can still reach the part and cause harm.

Building tricks

  • Antenna - Extended landing legs are often used as antennae for satellites.
  • Hangar doors - The legs can act as doors. Alternatives include Solar Panels.
  • Mechanical arms - For advanced builds.
  • Payload Bay- used to deploy payloads


  • The angle of the extension of the Landing Leg from its attached joint is about 115 degrees.
