The rover has arrived at an area that may show evidence liquid water flowed on this part of Mars for much longer than previously thought. NASA’s Curiosity rover has begun exploring a new region of Mars, one that could reveal more about when liquid water disappeared once and for all from the Red Planet’s surface. […]

Mars Reconnaissance Orbiter (MRO)
On Jan. 16, 2020, the Mars Reconnaissance Orbiter (MRO) captured this image of two types of sand dunes on Mars: barchan and linear dunes. The small dots are called barchan dunes, and from their shape we can tell that they are upwind. The downwind dunes are long and linear. These two types of dune each […]

This month marks the 20th anniversary of Spirit and Opportunity’s landing on Mars, part of a mission whose legacy will extend far into the future. In January 2004, twin NASA rovers named Spirit and Opportunity touched down on opposite sides of Mars, kicking off a new era of interplanetary robotic exploration. They arrived in dramatic […]

Videos from the rover show its shadow moving across the Martian surface during a 12-hour sequence while Curiosity remained parked. When NASA’s Curiosity Mars rover isn’t on the move, it works pretty well as a sundial, as seen in two black-and-white videos recorded on Nov. 8, the 4,002nd Martian day, or sol, of the mission. […]

Mars Reconnaissance Orbiter (MRO)
On Aug. 18, 2023, the Mars Reconnaissance Orbiter (MRO) captured ridged lines carved onto Mars’ landscape by the gradual movement of ice. While surface ice deposits are mostly limited to Mars’ polar caps, these patterns appear in many non-polar Martian regions. As ice flows downhill, rock and soil are plucked from the surrounding landscape and […]

Now at 1,000 days on Mars, the mission has traversed an ancient river and lake system, collecting valuable samples along the way. Marking its 1,000th Martian day on the Red Planet, NASA’s Perseverance rover recently completed its exploration of the ancient river delta that holds evidence of a lake that filled Jezero Crater billions of […]

In December 2022, NASA’s MAVEN (Mars Atmosphere and Volatile EvolutioN) mission observed the dramatic and unexpected “disappearance” of a stream of charged particles constantly emanating off the Sun, known as the solar wind. This was caused by a special type of solar event that was so powerful, it created a void in its wake as […]

This illustration made on Nov. 26, 1974, by Rick Giudice shows the Pioneer 10 spacecraft traveling through the asteroid belt between Mars and Jupiter, the largest planet in the solar system. At the time, it was uncertain whether it would traverse it safely since the density of particles large enough to damage the craft was […]
