Facial pareidolia is the human tendency or illusion of seeing facial structures in an everyday objects – such as seeing the “man in the Moon,” or the face of Jesus on a piece of toast. But here’s a newly found crater on Mars that might be a case of ‘bear-adoilia.’Continue reading “There's a Crater on Mars That Looks Like a Bear”
This interesting image from the HiRISE camera on the Mars Reconnaissance Orbiter shows a field of fascinating dunes called barchan dunes. These dunes have formed along a cliff in Chasma Boreale, in the North Pole of Mars.Continue reading “Beautiful Dunes on Mars, Sculpted by Swirling Winds”

Because of the orbiters and landers that have studied Mars over the years, scientists have learned that water ice is very likely locked away just under the surface throughout the planet’s mid-latitudes. These regions – especially in the northern hemisphere — are mostly covered with smooth material and scientists suspect ice is just underneath.
But sometimes, images like this give one from the HiRISE (High Resolution Imaging Science Experiment) camera on the Mars Reconnaissance Orbiter, provides a glimpse of the ice that might be buried below the surface. This image shows a cliff jutting out of the normally smooth terrain, and the cliff is covered with bright ice.Continue reading “This Ice Cliff is One of the Few Places With Exposed Water ice in the Mid-Latitudes on Mars. It’s Probably Tens of Millions of Years old”
Pit craters are found on solid bodies throughout our Solar System, including Earth, Venus, the Moon, and Mars. These craters – which are not formed by impacts — can be indications of underground lava tubes, which are created when the top of a stream of molten rock solidifies and the lava inside drains away, leaving a hollow tube of rock. If a portion of the roof of the tube is unsupported, parts of it may fall in, making a hole or a pit along the lava tube’s path.Continue reading “The Tharsis Region of Mars is Peppered With These Strange Pit Craters. Now They’ve Been Found Elsewhere”
From orbit, this landscape on Mars looks like a lacy honeycomb or a spider web. But the unusual polygon-shaped features aren’t created by Martian bees or spiders; they are actually formed from a ongoing process of seasonal change from created from water ice and carbon dioxide.Continue reading “This Bizarre Terrain on Mars is Caused by Water Ice and Carbon Dioxide”
Changes are always taking place on Mars, from factors like seasonal variations and wind. But there’s one other aspect that changes the surface of Mar quite often: impacts.
Here’s a new impact crater that was seen by the Mars Reconnaissance Orbiter. Exactly when the crater formed is not known, but this image was taken on July 24, 2020 and in a previous image of this site taken in 2018, the crater is not there.Continue reading “This Crater on Mars is Just a Couple of Years Old”
Most impact craters are usually circular and fairly symmetric, but not all. This odd-shaped crater on Mars is obviously an impact crater, but it has a unique oblong shape. What happened?Continue reading “Here’s Something Rare: a Martian Crater That isn’t a Circle. What Happened?”
More than 13 months after the Perseverance rover landed on Mars (on February 18, 2021), the rover’s cameras have finally spotted some of the parts of the Mars 2020 landing system that got the rover safely to the ground. The parachute and backshell were imaged by Perseverance’s MastCam-Z, seen off in the distance, just south of the rover’s current location. The image was taken on Sol 404, or April 6, 2022 on Earth.Continue reading “Perseverance Finally Spots its Own Parachute on the Surface of Mars”
China’s Tianwen-1 lander and Zhurong rover touched down on the Martian plain Utopia Planitia on May 14, 2021 after spending about three months orbiting the Red Planet. While the Chinese Space Agency has shared images of the rover and lander (including a cute family portrait taken by a wireless remote camera), NASA’s Mars Reconnaissance Orbiter has been following the rover’s travels from above.Continue reading “Mars Orbiter Captures Images of China’s Rover From Space”
