Mars shares many landforms and weather patterns with Earth, including changing seasons, volcanoes, canyons, dust storms, dust devils and water ice. Another feature that Earth and Mars share is polar ice caps. These are among each planet's striking features, but the major difference is that Earth's polar ice caps are both composed of water, while Mars' north polar ice cap is composed only of water and its southern polar ice cap is carbon dioxide.

Crater counts tell us that most of the Martian surface is more than 3 billion years old, but pieces of Mars we have on Earth tell a different story. The three main classes of Martian meteorites—shergottites, nakhlites, and chassignites—are all 2.4 billion years old or younger. Un

Meteors don't just burn up. What really happens is far more violent

Scientists have uncovered seven surprising stages that space rocks go through as they hurtle toward Earth, revealing that melting and violent fragmentation, rather than simple evaporation, determine their fate. The discovery could help explain why meteorites scatter across the gr
