Mars

Mars was doomed to desiccation by its small size, a new study suggests.

Following a botched first attempt, NASA's Mars Perseverance rover successfully collected a pencil-thin Martian rock core sample.

The largest piece of Martian rock on Earth, weighing around 32 pounds, has gone on display for the first time, at a museum in Maine.

Martian 'blueberry' stones may hold evidence of the planet's watery past, a new study of similar minerals on Earth suggests.

NASA's Perseverance rover's first sample collection didn't go as planned due to trouble with a "unique" and unexpectedly powdery Mars rock.

A small rock arch in Gale Crater is a whimsical example of the textures of Mars.

In this vast and lonely universe, are Earthlings just desperate for next door neighbors to play with?

Bright reflections that radar detected beneath the south pole of Mars may not be underground lakes as previously thought but deposits of clay instead, a new study finds.

Scientists used two years of marsquake data to map the interior of the Red Planet for the first time ever.

The findings from the Curiosity rover could help the Perseverance rover decide which samples to collect for later analysis.

Methane tends to only be made by biological life, so scientists are wondering if the source is from alien microbes.

China's first Mars rover has captured its first sounds of the Red Planet and beamed back stunning views of a drive on the dusty world.

China's first-ever Mars rover was on the move earlier this month, imagery by a NASA spacecraft shows.

NASA's experimental Mars helicopter has now flown eight times on the Red Planet, traveling farther than scientists hoped would be possible.

China's Zhurong rover has sent a new batch of images to Earth — including a "family photo" of the rover with its rocket-powered landing platform posing for a camera on the rock-covered surface.

Evidence of what may be the youngest eruption seen yet on Mars suggests the Red Planet may still be volcanically active, raising the possibility it was recently habitable.

For the past five weeks, Perseverance has been focused primarily on supporting and documenting the flights of NASA's Ingenuity helicopter. But the rover has been doing some science work, too.

China just successfully landed its first rover on Mars, becoming only the second nation to do so.

Unusual landforms on Mars' Arcadia Planitia appear to be debris-covered glaciers flowing on a flat plain.

Ingenuity aced its third-ever Martian flight early Sunday morning (April 25), adding to its already impressive resume.
