Awesome picture: HiRISE Spots Curiosity Rover at Mars' 'Woodland Bay'

A dramatic Martian landscape can be seen in a new image taken from space, showing NASA's Curiosity rover examining a location called "Woodland Bay." It's just one of many stops the rover has made in an area referred to as the "clay-bearing unit" on the side of Mount Sharp, a 3-mile-tall (5-kilometer-tall) mountain inside of Gale Crater.

Mars’ North Pole is Doing the Dust Storms Thing Again

Mars’ North Pole is Doing the Dust Storms Thing Again

It’s easy to take for granted the detailed, almost real-time knowledge of Mars that we have at our fingertips. After all, in the not-too-distant past, Mars was largely mysterious. All we had were ground-based images of the planet. Now? Now we have daily weather reports and images of dust storms.

Where Does Mars’ Methane Go? New Study Provides Possible Answer, with Implications in the Search for Life.

Where Does Mars’ Methane Go? New Study Provides Possible Answer, with Implications in the Search for Life.

For centuries, scientists have speculated about the existence of life on Mars. But it was only within the past 15 years that the search for life (past and present) really began to heat up. It was at this time that methane, an organic molecule that is associated with many forms of life here on Earth (i.e. a “biosignature”) was detected in Mars’ atmosphere.

Curiosity Sniffs a Spike in Methane. Could it be a Sign of Life?

Curiosity Sniffs a Spike in Methane. Could it be a Sign of Life?

Since it landed on Mars in 2012, one of the main scientific objectives of the Curiosity rover has been finding evidence of past (or even present) life on the Red Planet. In 2014, the rover may have accomplished this very thing when it detected a tenfold increase in atmospheric methane in its vicinity and found traces of complex organic molecules in drill samples while poking around in the Gale Crater.

Earth has a Water Cycle. Mars has a Dust Cycle

Earth has a Water Cycle. Mars has a Dust Cycle

To say there are some myths circulating about Martian dust storms would be an understatement. Mars is known for its globe-encircling dust storms, the likes of which are seen nowhere else. Science fiction writers and Hollywood movies often make the dust storms out to be more dangerous than they really are. In “The Martian,” a powerful dust storm destroys equipment, strands Matt Damon on Mars, and forces him into a brutal struggle for survival.

New layers of water ice have been found beneath Mars’ North Pole

One of the most profound similarities between Earth and Mars, one which makes it a popular target for research and exploration, is the presence of water ice on its surface (mainly in the form of its polar ice caps). But perhaps even more interesting is the presence of glaciers beneath the surface, which is something scientists have speculated about long before their presence was confirmed.

Why This Martian Full Moon Looks Like Candy

Why This Martian Full Moon Looks Like Candy

For the first time, NASA's Mars Odyssey orbiter has caught the Martian moon Phobos during a full moon phase. Each color in this new image represents a temperature range detected by Odyssey's infrared camera, which has been studying the Martian moon since September of 2017. Looking like a rainbow-colored jawbreaker, these latest observations could help scientists understand what materials make up Phobos, the larger of Mars' two moons.

Curiosity has Finally Sampled a Clay-Rich Region on Mars

Curiosity has Finally Sampled a Clay-Rich Region on Mars

It’s hard to believe that MSL Curiosity has been on Mars for almost seven years. But it has, and during that time, the rover has explored Gale Crater and Mt. Sharp, the central peak inside the crater. And while it has used its drill multiple times to take rock samples, this is the first sample it’s gathered from the so-called ‘clay unit.’

Mars Helicopter Completes More Test Flights. It’s Almost Ready to go to Mars

Mars Helicopter Completes More Test Flights. It’s Almost Ready to go to Mars

We’ve known for some time that NASA is sending a helicopter to Mars. The vehicle, called the Mars Helicopter, is undergoing flight testing at NASA’s Jet Propulsion Laboratory in California. The little helicopter will make its eventual way to Mars as part of the Mars 2020 Rover mission.

Methane on Mars: a new discovery or just a lot of hot air?

Methane on Mars: a new discovery or just a lot of hot air?

The discovery of life on Mars would get pretty much everyone excited. But the scientists hunting for it would probably be happy no matter what the outcome of their search – whether life turned out to extinct, dormant or extant. They’d even consider finding no evidence of life whatsoever to be an important discovery. But, as the saying goes, absence of evidence is not evidence of absence, and it will take many decades of detailed exploration of Mars to be reasonably sure that life has always been absent there.

Rivers on Mars Flowed for More Than a Billion Years

Rivers on Mars Flowed for More Than a Billion Years

The ancient climate of Mars is a mystery to scientists. Even with all we’ve learned about Mars, it’s still difficult to explain how lakes and rivers existed. A new study shows that Martian rivers were swollen with runoff and that they flowed far later into the planet’s history than previously thought.
