Conclusions
• TC:– 3 kW– 390 kg– 30.5 m3 total (0.5 fuel cell)
• *CS1, CS2, CS3:– 2.1 kW– 49.31 m2 x 0.1016 ≈ 5 m2 (2 panels 2.5 m x
9.83 m)– 198.96 kg (battery, structure, wires, panels)
• dE, aM, dM, aE: - 0.1 kW - 106 kg (total) - 0.07 m3

ω = 2π/(24 hours 39 minutes 35.244 seconds)r = (GM/ω2)1/3 , G = 6.67300 × 10-11 m3 kg-1 s-2
M = 6.4191 x 1023 kg5.3% of orbit = 1.30 hrs
AAE450 Senior Spacecraft Design
• TC (2.8 kW need)– 360 kg + 30 kg = 390 kg– 0.5 m3 + 30 m3 = 30.5 m3
– Based on numbers from Steve
• dE, aM, dM, aM– Based on numbers from Mike– 0.1 kw– 98 kg (battery) + 5 kg (structure) + 3 kg (wires)– 0.07 m3
