2 Ares V Gross TLI Capability Requirement: Crewed Outpost Lander Mission

Metric (mT) English (lbm) • Earth to Orbit Derived Performance Requirement Orion 20.2 44,500 – = Lander + L2MR + L3MR Lander (Crew)* 45.9 101,192 – > 45 t (CARD) Level II Margin 4.0 8,818 • TLI Derived Performance Level III Margin 5.0 11,023 Requirement Total TLI Capability 75.1 165,567 – = Lander + Orion + L2MR + Total ETO Capability 54.9 121,034 L3MR *Includes Lander Adapter – > 67 t (CARD)

• ETO Mission Destination: 130 nmi, 29 degrees • Loiter Duration 4 days (CARD TBD) • TLI Maneuver Starting Conditions: 100 nmi, 29 degrees • TLI delta-V = 3175 m/s + Gravity Loss

3 Ares V Gross TLI Capability Requirement: Cargo Outpost Lander Mission

Metric (mT) English (lbm) • Earth to Orbit Derived Performance Requirement Lander (Cargo)* 54.5 120,152 – = Lander + L2MR + L3MR Level II Margin 4.0 8,818 – > 54.6 t (CARD) Level III Margin 5.0 11,023 • TLI Derived Performance Total TLI Capability 63.5t 139,994 Requirement Total ETO Capability 63.5t 139,994 – = Lander + L2MR + L3MR *Includes Lander Adapter – > 54.6 t (CARD)

• ETO Mission Destination: Phasing Orbit • Loiter Duration: None (no loiter capability on EDS)

Note: Saturn V TLI Payload Capability was 48.6t (Apollo 17 - CM/SM/ LM/SLA), Ares V Earth-to-TLI requirement exceeds Saturn V Capability by 31%
