The PB-X50R Xenon Container is a radially attachable xenon gas tank. Its volume is slightly more than half that of the larger PB-X150 Xenon Container.

Product description

The X50R is a small-volume Xenon container, heralded by engineers for being ideally suited for small ion-driven spacecraft, and also for having thoroughly disproved management in their notion that a smaller fuel tank would make the fuel cheaper.


The PB-X50R Xenon Container provides xenon gas to the IX-6315 "Dawn" Electric Propulsion System, the only ion engine. Unlike liquid fuel and oxidizer, and like monopropellant, xenon gas does not require fuel crossfeed; the Dawn engine can drain xenon gas from any fuel tank, even if the engine and tank aren't connected with fuel crossfeed capable parts.

The PB-X50R stores 405 units of xenon gas; since xenon has a density of 0.1 kg (0.001 t) per unit, the tank stores 0.405 tons of xenon. This allows it to power a Dawn ion engine for 833.3 s (13 m, 53.3 s) at full thrust.


  • The PB-X50R is the only xenon gas tank not manufactured by Probodobodyne Inc.
  • The PB-X50R was originally from the KSPX parts mod; several parts from KSPX were added to the stock game in version 0.21.


  • Parts can now be radially attached to PB-X50R Xenon Container
  • Decreased tech cost from 9600 to 7800
  • Increased cost from 2200 to 2220
  • Decreased mass from 0.03143 to 0.0135
  • Xenon supply increased from 400 to 405
  • Moved to Propulsion from Utility.
  • Initial release
