The Most Dangerous Game

• HERCULES provides constant safety monitoring
• Pressurization, rover systems, life support, crew
  vitals
• Rescue upon
• Crews request
• Loss of communication
• Permanent immobilization of rover
• Imminent threat
• Any other combination of failures
• But our rescue strategy begins with locality

• Ballistic medevac vehicle
• Exchanges long trip times for
• High propellant requirements
• Frequent use requires ISRU
• Advanced tech a plus
• Precision rocketry
• Long conceptual history

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
STEX enables rapid egress/entry sans airlock with
dust mitigation

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 overHUP-T crew is concussed!
• Minotaur flips HUP-T uprightSTEX shed as
  crewmember two enters to treat victims

But MoonHIND might require a development race of
its own!
