View Full Version : Discussion: Big Dunes on Mars

2003-Nov-10, 11:17 PM
SUMMARY: Mars has the largest volcano, the deepest canyon, and it's got the biggest sand dunes. Several conditions on the Red Planet, including its low gravity, air pressure and sand probably contribute to the gigantic sand dunes that can form there. Dunes have been seen by the Mars Global Surveyor which reach twice as tall as they get on Earth. The Mars Exploration Rovers, currently on track to reach Mars in early 2004 will have cameras on board that may help scientists take a closer look at the sand that makes up these gigantic dunes.

Is it easier to travel over soft sand or rocky terrain (for our research vehicles)? Seems that both have their advantages and disadvantages.
