Mars

Four volunteers exited a mock Mars habitat at NASA's Johnson Space Center on July 6, bringing the agency's first year-long simulated Red Planet mission to an end.

New photos from the European Space Agency's Mars Express orbiter give us our best look yet at a giant ravine on the Red Planet. The dark "scar" was likely birthed by a gigantic blob of magma hidden beneath a massive nearby volcano millions of years ago.

The starchy-looking moon Phobos, destined to crash into Mars' surface, has been revealed in new detail by NASA's Mars Reconnaissance Orbiter. The 'space potato' image was recently shared on NASA's Instagram.

NASA's Perseverance rover spotted a bizarrely light-toned boulder on Mars, the likes of which have never been seen before.

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.

Once thought impossible to exist, water frost found atop Mars' Tharsis region volcanoes could come in handy for future human exploration missions, new research suggests.

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.

This pit crater making recent headlines may open into a larger cave that could provide a sheltered environment for both astronauts and hypothetical Martian life.

Potentially hazardous asteroids pose a risk to Mars missions, but they can also yield insight into the history of the Red Planet and the early solar system, new research suggests.

Previously unpublished photos of Mars' moon Phobos hint that the mysterious satellite may actually be a trapped comet — or perhaps just a piece of one, along with its twin moon Deimos.
