Soviet Soyuz Tanker

File Description:
Based upon an early proposal for a Soyuz upper stage that was to be used as a refuelling vessel for long duration missions. This upper stage can refuel any docked vessel with up to two different propellant resources; the capacity of the tank can be configured in the scenario file, using a default value of 6000 kg. Using higher values is not advised since it may compromise the capability of the launch vehicle to lift this stage into orbit. This version introduces particle exhaust and a fix to the guidance algorithm that allows for multiple simultaneous launches. Based on original work bye mcdope and rjcroy
