NASA Has Just Released Breathtaking New Photos of Mars And They Are Marvellous

Sand dunes on Mars are fascinating. They shift and move in different ways than they do on Earth, and they can grow to much more immense sizes than on our own planet. Several conditions contribute to the gigantic sand dunes and large fields of dunes that can form on the Red Planet, including its low gravity and air pressure. Seasonal changes affect the Martian sand dunes, as well. Frosty dunes on Mars. Credit: NASA/JPL/UArizona.
