Reference Case 1:  Earth - Mars flyby

Mission Description

  • Launch from Earth on Julian date 2452779.5 (May 20, 2003) -- fixed
  • Arrive at Mars on Julian date 2452979.5 (Dec. 6, 2003) -- fixed
  • Initial mass:  585.0 kg (fixed)
  • Launch V ∞ magnitude:  1.66 km/s (fixed)
  • Launch V ∞ direction is free
  • Propulsion Model:  Electric Engine G (1 Engine)
  • Power Model: apsa1 solar array, P0 = 6.0 kW, Psc = 0
  • Objective function:  final mass
  • Originally modeled using SEPTOP

Additional Mission Options

A. Same as Reference Case 1 except now the launch date is free. (Allow transfer duration to vary so that arrival date remains fixed).
B. Same as Reference Case 1 except now the flight time is free (optimize the arrival date with a fixed departure date, and therefore, a variable flight time).
C. Same as Reference Case 1 except now the launch V¥ magnitude is free.  Launch vehicle:  Delta 7326-9.5.
D. Same as Reference Case 1 except now the reference power P0 = 3.0 kW.
E. Same as Reference Case 1 except now the launch date, arrival date, and launch V¥ magnitude are all free.  Launch vehicle:  Delta 7326-9.5.
F. Solar Sail Propulsion

  • 100x100 m**2 solar sail with a mass of 260.75 kg.
  • minimizing flight time
  • launch date is free but around 200
