Total mass of the IM is 489 kg.
The Reaction Control System (RCS) and Fuel Cell are housed in the IM. Each is operated using LH2 and LO2.
Gaseous Hydrogen (GH2) will be used for pressurization of the OTV and IM LH2 tanks.
Gaseous Nitrogen (GN2) will be used for pressurization of the OTV and IM LO2 and LN2 tanks.
Wastewater (WLH2O) generated as a byproduct of the Fuel Cell will be dumped overboard.
