  1. Lunar Orbit CircularizationToy Ball MaterialsLunar Access with Ground Tracking February 26, 2009 [Kara Akgulian] [Mission Ops]

  2. Impulse Thrust • Chart shows only boost in first orbit • Δv without boost is 0.38 m/s • Isp= 280 s • Mass of OTV=600 kg • Launch Cost/kg=$4292 • Cost’s are additional TOF= Time of Flight [Kara Akgulian] [Mission Ops] • Solid Only • Boost of: 10m/s,25m/s,50m/s,100m/s,200m/s • Split Between: 1st Orbit, 1st and 2nd Orbits and 1st, 2nd and 3rd Orbits • 3 Orbits: 1.) rp=1837.4 km ra=50000 km 2.) rp= 2737.4 km ra=525000 km 3.)rp= 2737.4 km ra=55000 km

  3. Continuous Burn • Assumptions: • Constant Thrust at Optimum Level • Working with Energy Equations • Optimum Pointing Angle • Costs are additional • Values Used: • EP Isp= 1800 s • Solid Isp= 280 s • Mass of OTV=600 kg • Launch Cost/kg=$4292 • EP Mass Flow Rate=5.6x10-6 kg/s • Solid mass Flow Rate=1.8 kg/s [Kara Akgulian] [Mission Ops] Electric Propulsion Solid Propulsion
