A parachute being half deployed

The Parachute is used for slowing down on an object with an atmosphere, such as The Sun, Earth, Venus, Mars and Jupiter. Parachutes are useless on objects without an atmosphere because there is no air in space.

It has two stages: partial deployment and full deployment. Partial deployment will not prevent parts from breaking on contact. Full deployment will slow down most spacecraft to below velocities that cause the rocket to be destroyed. A parachute can be cut. 

Since Mercury, The Moon, Io, Ganymede and Callisto have no atmospheres, you cannot deploy parachutes.

The parachute cannot deploy at speeds greater than 250 m/s or less than 3 m/s. It also cannot deploy in a vacuum such as space. The parachute needs to be lower than 2500 meters high (6250 in Mars or 7500 in Jupiter) to half deploy, and under 500 meters (1250 in Mars or 1500 in Jupiter) to fully deploy.


  • A partially-deployed parachute fully deploys automatically at half the full deployment height above the ground level.
  • Even though Europa has an atmosphere, the atmosphere is too thin to deploy a parachute in.
  • Before 1.4, parachutes used to adapt to parts that were placed above them, such as docking ports, so you could make seamless connections. Currently, they do not adapt, and this may be due to a bug or change in the part file.
  • If you deploy a parachute just after liftoff and leave it, it will stay deployed until you cut it. However, they have no effect in outer space as there is no air to turn into drag.
  • A parachute auto-cuts when the rocket lands.
  • Fuel tanks adapt to parachutes.

A fully deployed parachute

  • Fuel tanks have a density of 0.625t/m2, and an upright and upside-down parachute on either end of a fuel tank will make it thinner on both ends. Its density remains constant, but its mass is reduced to 4/5ths of what it would be, were it about 2-wide. This means the underside of a parachute is 1.6 squares wide, but the widest point is 2 wide, as its bottom tapers, as well as its top.
  • The parachute can be attached into the top of a capsule.
  • Before 1.5, the parachute must be moving slower than 50 m/s to fully deploy.
  • A parachute loses its cover when it is deployed.
  • A player can make thin fuel tanks using the parachute’s adaption to fuel tanks feature. However, the real 2 wide tanks can be only found in blueprint editing.
  • If you connect a random part above a parachute (like another parachute or structural part), and deploy it, the parachute and that part would stay as in one piece.
