Using Percussive, Dynamic, and Static Soil Penetrometers to Assess Geotechnical Properties and the Depth to Ground Ice of the Mars and Lunar Analog Terrains on the Devon Island, Canadian Arctic
In the summer of 2011, we used three geotechnical instruments to assess the ground conditions in planetary analog sites on the Devon Island, Canadian High Arctic. The instruments included Percussive Cone Penetrometer (PCP) developed by Honeybee Robotics, and the two off the shelf instruments: Dynami...
