Mars

NASA's long-running Mars Odyssey orbiter celebrated its 100,000th orbit with a fresh view of Olympus Mons, the largest volcano in the solar system.

Small asteroids have the Red Planet in their crosshairs more often than not, as Mars lander's seismometer detects their impacts.

Scientists won't only study the rocks NASA's Perseverance rover has cached throughout its trek across Mars. They want the fresh Mars air, too.

NASA's Perseverance rover has begun studying an intriguingly light-colored patch of rock that mission team members call "Bright Angel."

Some scientists believe they may be able to find buried liquid water on the Red Planet by studying seismic and magnetic readings to reconstruct the aftermath of marsquakes.

New research shows that the speed of sound on Mars varies considerably by location and temperature. The findings could help scientists understand sounds picked up by Martian rovers, as well as make future crewed ventures safer.

Volcanic meteorites from Mars give scientists a glimpse into the planet's structure.

A powerful solar storm in May 2024 created auroras on Mars and provided scientists with crucial information that could aid future crewed missions to the Red Planet.

NASA's fleet of robotic Martian explorers measured the effects of May's dramatic solar storms, experiencing the equivalent of undergoing about 30 chest X-rays all at once.
