Mars

NASA's Journey to Mars requires cutting-edge technologies to solve the problems explorers will face on the Red Planet.

As the Mars Pathfinder spacecraft approached its destination on July 4, 1997, no NASA mission had successfully reached the Red Planet in more than 20 years.

NASA's Mars Opportunity rover is examining rocks at the edge of Endeavour Crater for signs that they may have been either transported by a flood or eroded in place by wind.

Artificial intelligence is changing how we study Mars.

NASA's Mars Exploration Rover Opportunity passed near a young crater this spring during the 45th anniversary of Apollo 16's trip to Earth's moon, prompting a connection between two missions.

MAVEN is bringing insight to how the sun stripped Mars of most of its atmosphere, turning a planet once possibly habitable to microbial life into a barren desert world.

New research shows that water from melted snow and ice likely carved valley networks around Lyot crater on Mars.

This 70 km-wide crater and its surrounds offer a window into the watery past of the Red Planet.

NASA has found diverse minerals in rocks collected by the Curiosity rover in lower Mount Sharp, Mars. This suggests that wet environmental conditions there changed over time.

New study suggests the Red Planet's surface was once much more watery than previously thought.
