MDRS EVA 04 Report: Geology Work – Conical Penetrometer Blow Count & Core Sample Tests

Dec 19th, 2011 | By | Category: Aerospace, Mars Desert Research Station

We are not alone...

Today we had the longest EVA so far: 13.5 miles/3.5 hours. We visited two geological sites and did Blow Count Penetrometer and Core Samples Tests. With this information we will be able to determine the soil strength and composition which in a Mars mission will support decisions on where to mine based on water/mineral content and how to get there.
