Planetary surface exploration using a network of reusable paths

摘要

A network of reusable paths (NRP) allows for a new approach to planetary surface exploration using a mobile robot. NRP gives the robot the ability to accurately return to any previously visited point. This allows mission-level improvements by enabling parallel exploration of scientific targets. NRP would be particularly useful for sample-return missions to the Moon or Mars. The approach was tested in a mock Lunar sample-return mission near the impact crater located in Sudbury, Ontario, Canada. There, NRP enabled nearly twice as many sites to be investigated as compared to a serial approach to exploration. In this mock mission, the robot drove more than 3.9 km, allowing for in situ analysis and sample collection and return at many sites.
