Monopropellant is a resource that is used by most RCS thrusters along with the O-10 MonoPropellant Engine. It is stored in separate tanks from liquid fuel or oxidizer, and may be transferred around a vessel. Crew containing command modules also store a small quantity of monopropellant. Stored monopropellant is available to every thruster on a vessel. As of version version 0.23.5, containers on earlier stages are drained before containers on later stages.
Monopropellant is also used by the jetpacks worn by Kerbals on EVA. Each kerbonaut can carry 5 units, which is enough for about 600 m/s of Δv. The jetpack is resupplied when the kerbonaut enters a command module, but as of version 1.0.2[outdated] this action does not remove any monopropellant from the craft's supply.
