Defrosting Dunes On Mars

This captivating image was taken in the north polar region of Mars by the ESA/Roscosmos ExoMars Trace Gas Orbiter's CaSSIS camera.

Avalanche Season On Mars

Every spring the sun shines on the side of the stack of layers at the North Pole of Mars known as the north polar layered deposits. The warmth destabilizes the ice and blocks break loose.

The Formation Of The Martian Moons

Almost all the planets of our solar system have moons. Each planetary system has however unique characteristics.

A key tracer used to estimate how much atmosphere Mars lost can change depending on the time of day and the surface temperature on the Red Planet, according to new observations by NASA-funded scientists.

Scientists have taken an important step towards revealing the mysterious source of methane on Mars, by refining estimates of the gas in the planet's atmosphere.

Mars Express Examines Terra Cimmeria

ESA's Mars Express has captured the cosmic contrast of Terra Cimmeria, a region in the southern highlands of Mars marked by impact craters, water-carved valleys, and sand and dust in numerous chocolate and caramel hues.

It has traveled a total of 13 miles (21 kilometers) and ascended 1,207 feet (368 meters) to its current location. Along the way, Curiosity discovered Mars had the conditions to support microbial life in the ancient past, among other things.

ESA's Mars Express has been keeping an eye on local and regional dust storms brewing at the north pole of the Red Planet over the last month, watching as they disperse towards the equator.

Meteors Help Martian Clouds Form

How did the Red Planet get all of its clouds? CU Boulder researchers may have discovered the secret: just add meteors.

How Webb Will Explore Mars

In the summer of 2018, a dust storm blanketed the entire planet Mars. From the surface, the Sun would have looked like tiny orb in a murky brown sky.

InSight Images Clouds on Mars

NASA's InSight used its Instrument Context Camera (ICC) beneath the lander's deck to image these drifting clouds at sunset

Curiosity Finds a Clay Cache On Mars

NASA's Curiosity rover has confirmed that the region on Mars it's exploring, called the "clay-bearing unit," is well deserving of its name.

Science fiction stories are chock full of terraforming schemes and oxygen generators for a very good reason -- we humans need molecular oxygen (O2) to breathe, and space is essentially devoid of it. Even on other planets with thick atmospheres, O2 is hard to come by.

From disrupted biological clocks to radiation and contamination hazards, Europe is running experiments on the International Space Station to take human exploration one step closer to Mars.

Ashfall from ancient volcanic explosions is the likely source of a strange mineral deposit near the landing site for NASA's next Mars rover, a new study finds.

Wind has shaped the face of Mars for millennia, but its exact role in piling up sand dunes, carving out rocky escarpments or filling impact craters has eluded scientists until now.

Russian and German physicists have offered an explanation for the new data obtained by Martian satellites, capturing the "escape" of hydrogen atoms from the upper Martian atmosphere into outer space.

A camera on the spacecraft's robotic arm snapped the photos on April 24 and 25, the 145th Martian day, or sol, of the mission.

NASA's Mars InSight lander has measured and recorded for the first time ever a likely "marsquake."

The long-standing debate on the existence of ancient oceans on Mars has been recently revived by evidence for tsunami resurfacing events that date from the Late Hesperian geological era.
