1. What are the major recent technological advances that will help us understand the terrain and environment with respect to off‐road and cross country vehicle operations?
Everyone is Flying Drones!
a) Geophysical and remote sensing capabilities
High Resolution images are common place
a) Geophysical and remote sensing capabilities

2. What aspects of the terrain and environment have the largest impact on vehicle operations in extreme
environments?
a) Poorly understood terrain:
We seldom operate in dry, sandy soil. We need better understanding of the physics in highly organic, wet soils
2. What aspects of the terrain and environment have the largest impact on vehicle operations in extreme
environments?
a) Poorly understood terrain mechanics:
We seldom operate in dry, sandy soil. We need better understanding of the physics in highly organic, wet soils, which are STRONGLY influenced by cold temperatures!
2. What aspects of the terrain and environment have the largest impact on vehicle operations in extreme
environments?
b) Unaccounted for, or harsh weather:
Freeze/thaw impacts
Polar regions storms
2. What aspects of the terrain and environment have the largest impact on vehicle operations in extreme
environments?
c) Unknown and otherworldly surface conditions:
3. What do you feel is the most significant advance needed in the field of terramechanics?
3. What do you feel is the most significant advance needed in the field of terramechanics?
Terrain mechanics characterization that:
a) applies to a wide range of scales
b) is easy to predict
c) easy to measure
d) able to be sensed remotely
e) accurate!!!
“Look deep into nature and you
will understand everything better”
