Marsquake Reveals Molten Layer Above Martian Core
An impact far from NASA's Insight lander on Mars set off seismic waves that revealed new details about the Martian interior.
What Mud Cracks Mean for Life on Mars
Mud cracks are evidence for sustained wet-dry cycles on ancient Mars, which might have provided conditions amenable to life (with caveats).
Perseverance Finds Complex Organics (Not Life) on Mars
NASA's Perseverance has sniffed 10 rock samples and found signatures of organic molecules, a sign of a complex geochemical past.
The Moon Deimos Might Be a Piece of Mars
Surprising new results from the United Arab Emirates' Hope probe call the origin of Mars's smaller moon into question.
Listen to a Martian Dust Devil
The Perseverance rover on Mars has recorded a dust devil using its microphone, providing unprecedented data about these whirlwinds.
See Bright Mars Wink Out Behind the Moon
The night of December 7–8 will be an exciting one for fans of the Red Planet. Not only will Mars be at opposition, but the full Moon will blot it out of the sky for many locations on Earth.
NASA Lander and Orbiter See (and Feel) New Mars Impacts
NASA's Mars Insight lander and Mars Reconnaissance Orbiter have witnessed two fresh new planet-probing impacts.
Perseverance Finds Ancient Habitable Conditions on Mars
The mission team has reported results from Perseverance's study of the rocks deposited by the river that once flowed into Jezero Crater.
Perseverance Watches Wild Winds on Mars
NASA’s Perseverance rover is recording the windy weather in Jezero Crater, chronicling its role in making the Red Planet dusty.
Mission Update: Mars and the Moon
Mission teams presenting at this week's Lunar and Planetary Science Conference provided updates on the Perseverance and Zhurong rovers at Mars, Chang'e 5's lunar sample return, and more.
Evidence Hints at Ancient Life on Mars
Scientists have found a chemical signature that hints at ancient life on Mars. But other possible explanations remain.
Mariner 9: The Martian Semicentennial
A half century ago, Mariner 9 — our first orbiter at another planet — showed us the real Mars.
Mars Hosted Supervolcanoes in the Ancient Past
Scientists have found massive ash deposits that formed over millions of years of volcanic super-eruptions, the first evidence for such explosive activity on Mars.
ESCAPADE Blue and Gold Orbiters Head to Mars in 2024
A pair of spacecraft will head to Mars in 2024 as the ESCAPADE mission, to study the Martian space weather environment.
Discovery of a Recent Martian Mudslide
A geologically recent landslide on Mars appears like mudslides on Earth — but it would have required water during a time when Mars was expected to be dry.

Mars Perseverance Rover Hits a Snag on First Sampling Attempt (Update)
Perseverance came up empty on its first attempt to grab and stow a sample of Mars.
"Liquid Water" Below Martian Surface Might Be Clay
Mysterious spots that scientists thought were subsurface lakes beneath the Martian south pole may instead be ancient clay deposits.
NASA’s Curiosity Takes Step Toward Solving Mars Methane Mystery
New measurements from NASA’s Curiosity rover show that methane concentrations near the Martian surface vary on a daily cycle. The finding could help reconcile conflicting data.
More Mysterious Buried Splotches on Mars Might Not be Liquid Water
Astronomers find more bright spots underneath Mars's south polar cap, but could they really be subterranean lakes?
Water-Ice Clouds Could Have Warmed Early Mars
New simulations show that the greenhouse effect of high water-ice clouds could have warmed early Mars, permitting the presence of long-ago lakes.
