1. Rescue: Scenarios and Solutions Derek Shannon

2. 2-Dec-04 USC 2004 AME 557 Space Exploration Architecture The Most Dangerous Game  HERCULES provides constant safety monitoring Pressurization, rover systems, life support, crew vitals  Rescue upon: Crew’s request Loss of communication Permanent immobilization of rover Imminent threat Any other combination of failures  But our rescue strategy begins with locality

3. 2-Dec-04 USC 2004 AME 557 Space Exploration Architecture L1, Lunar Orbit Too Slow

4. 2-Dec-04 USC 2004 AME 557 Space Exploration Architecture Lunar surface: Fastest rescue with maximum availability and resources

6. 2-Dec-04 USC 2004 AME 557 Space Exploration Architecture MoonHIND will chase HERCULES!  Ballistic medevac vehicle  Exchanges long trip times for: High propellant requirements  Frequent use requires ISRU  Advanced tech a plus Precision rocketry  Long conceptual history: See Lockheed’s Lunar Surface Ballistic Vehicle (LSBV) at right “Moon Hopper Interrupts Needless Death”

7. 2-Dec-04 USC 2004 AME 557 Space Exploration Architecture MoonHIND will chase HERCULES!  Ballistic medevac vehicle Max one-way transit of 2000 km in 34 minutes  Exchanges long trip times for: High propellant requirements Precision rocketry  Long conceptual history: See Lockheed’s Lunar Surface Ballistic Vehicle (LSBV) at right “Moon Hopper Interrupts Needless Death”

12. 2-Dec-04 USC 2004 AME 557 Space Exploration Architecture HERCULES will have a Moonitaur!

13. 2-Dec-04 USC 2004 AME 557 Space Exploration Architecture Speed, gurney, debris-clearing, and jaws-of-life functionality

14. 2-Dec-04 USC 2004 AME 557 Space Exploration Architecture Our rescuers still want EVA flexibility: Achilles protected by the Styx…

15. 2-Dec-04 USC 2004 AME 557 Space Exploration Architecture HERCULES protects rescuers with STEX (SuiT Envelopes for Xtra vehicular activity)  Unpressurized for rescuers  Simpler “rescue ball” version can be pressurized for accident victimes

16. 2-Dec-04 USC 2004 AME 557 Space Exploration Architecture STEX enables rapid egress/entry sans airlock with dust mitigation

17. 2-Dec-04 USC 2004 AME 557 Space Exploration Architecture A rescue scenario  Communication lost with HUP-T Rover! 1000km from South Pole base “Highly Undesirable Pogo Transit”  MoonHIND scrambles to the rescue! 2-member crew suits up, depressurizes capsule en route  One enters Moonitaur, the other wears STEX “Antler” retros prevent blasting HUP-T with dust upon arrival Landing legs contract, bringing capsule near surface STEX-rescuer rides Moonitaur to the scene  HUP-T has flipped over—HUP-T crew is concussed! Minotaur flips HUP-T upright—STEX shed as crewmember two enters to treat victims…
