Xenon gas

Xenon gas is a resource that fuels ion engines.

Uses

There are only two xenon gas related parts available at the moment. No other uses aren't currently planned. The PB-X150 Xenon Container is a storage container and the PB-Ion Electric Propulsion System then uses this xenon to propel the craft. Currently, there is only one Xenon container and one ion engine in the standard Kerbal Space Program, but a radial xenon tank, a larger xenon tank and a larger ion engine are included in an addon called KSPX.
