Why is there a spiral around the North Pole of Mars?
This image from NASA’s Mars Reconnaissance Orbiter (MRO) of northern Meridiani Planum shows faults that have disrupted layered deposits.
Selfies are so frequent that it’s not easy for them to capture our attention any longer. But when a Curiosity rover takes a selfie… on Mars… well, that’s another story. The photo was taken in 2015, but it was recently shared on APOD, where it immediately caught my eye. The low-angle selfie shows the rover above […]
On November 14, 1971, Mariner ( took this image of a shield volcano on Mars.
It was spring in the Northern hemisphere when this image was taken on May 21, 2017, by the HiRISE camera on NASA’s Mars Reconnaissance Orbiter. Over the winter, snow and ice have inexorably covered the dunes. Unlike on Earth, this snow and ice is carbon dioxide, better known to us as dry ice.
Last month, NASA’s Curiosity Rover captured a remarkable sight in the sky above Mars. It shot clear images of wispy cirrus clouds that look like those we have on Earth. While they’re common on our planet, they are very rare on the Red Planet, which is one of the things that make these images so […]
Toward the right side of this enhanced-color scene is a broad notch in the crest of the western rim of Endeavour Crater on Mars. Wheel tracks in that area were left by NASA’s Mars Exploration Rover Opportunity as it observed “Perseverance Valley” from above in the spring of 2017.
Various researchers are often pre-occupied with the quest for flowing water on Mars.
This illustration depicts NASA’s Mars 2020 rover on the surface of Mars. The mission, targeted for launch in July/August 2020, takes the next step by not only seeking signs of habitable conditions on Mars in the ancient past, but also searching for signs of past microbial life itself.
This 360-degree mosaic from the Mast Camera (Mastcam) on NASA’s Curiosity Mars rover looks out over a portion of the Bagnold Dunes, which stretch for several miles.
