Mission Description

Low power SEP Insertion Trajectory into a Quasi-Periodic Orbit at the Exterior Libration Point of the Sun-Earth/Moon System. Model includes only the gravity of the Earth, Moon, and Sun and these follow a realistic ephemeris.

• Departure date Dec 1 2010 <= T0 <= Jan 31 2011
• Initial Orbit LEO 200 KM altitude
• Inclination Free
• Ascending Node Free
• Argument of Periapsis Free
• Total Transfer Time Free
• Injection Free departure; V_infinity magnitude and direction free
• Initial Mass not tied to a Launch Vehicle; initial mass after injection maneuver is 2500 kg.
• Power P0 = 1 kW, Psc = 0 kW.
• Thrust Magnitude :09 N ≤ T ≤ 0:11 N
• Engine Degradation None
• Coast Periods allowed if optimal
• Target Orbit L2 Halo or Lissajous with z-axis amplitude ≤ 200K km, y-axis amplitude ≤ 500K
• Arrival Date ≤ May 1 2011
• Final Mass Maximize
• Originally modeled using Copernicus
