Global ExploraIon Roadmap
NESF 2015 HI-‐SEAS.ORG 3
• “Demonstrate autonomous crew operaGon capability.”
• “Explore landing sites of interest for extended duraGons.”
• “ConducGng high priority science benefiGng from human presence.”
• “Characterizing human health and performance.”
• “Demonstrate extended crew mobility and habitaGon systems.”
Why HI-‐SEAS? To miGgate risk on long-‐dura*on, high-‐latency missions via:
• High-‐fidelity mission profile and environment.
• Site that allows both crew isolaGon and easy access year-‐round.
• Astronaut-‐like crews. • Tracking crew cogniGve and team performance through collaboraGve field tasks.

Going forward
• Lava tube geophysics study during 12-‐month mission.
• More missions during 3rd NASA grant from 2016-‐2019.
• ConGnue to study autonomous crew EVA operaGons on high-‐latency, long-‐duraGon missions.
