Sandblasting winds shift Mars' landscape
High winds are a near-daily force on the surface of Mars, carving out a landscape of shifting dunes and posing a challenge to exploration, scientists said Tuesday.
Travelling dunes encroach on infrastructure, and reveal geological pattern
Recent research shows shifting sand dunes threaten to envelop several important Mid West roads within the next few years.
The physics of ocean undertow: Small forces make a big difference in beach erosion
People standing on a beach often feel the water tugging the sand away from under their feet. This is the undertow, the current that pulls water back into the ocean after a wave breaks on the beach.
Mars Rover Update
