Assumptions
No trails, roads, or landmarks for way-finding Localization is available (i.e. GPS) Astronauts are walking, not traversing via rover Astronauts are partially physically encumbered Astronauts are not just navigating, but are multi-tasking while navigating terrain

Software Methodology: Test-Driven Development
TDD: Testing before implementation Write code tests that fail before writing new implementation logic 2P Review: All code must be reviewed and critiqued by another team member
