Transfer vehicle artificial gravity

Transfer Vehicle Artificial Gravity

Propellant Needs

  • Artificial gravity spin-up propellant contained within the TV

  • Engine nozzles for spin-up on TV

  • All other propellant in large tanks at opposite end of the truss from the TV

  • Spin-up maneuver takes less than 30min

  • TV is spun-up after the Earth and Mars departure burns

  • TV is spun-down after the Earth and Mars arrival burns

  • Artificial gravity still active during mid-course burns
