Data from NASAs Mars Reconnaissance Orbiter reveals water flowed on Mars as recently as 2 billion to 2.5 billion years ago, say researchers at Caltech, Pasadena, California.

It is commonly believed that water on Mars evaporated about 3 billion years ago.But two scientists studying data from NASAs Mars Reconnaissance Orbiter found signs of liquid water on the Red Planet as recently as 2 billion to 2.5 billion years ...

Few celestial objects have fascinated humankind throughout history more than the Red Planet. For over a century, weve longed to know more about Mars and the beings that we speculated lived there. When NASA dispelled the notion of creatures scurrying along the rusty plains, it raised a more tantalizing prospect: that Mental Floss spoke to Kirby Runyon, a research scientist at the Johns Hopkins University Applied Physics Laboratory, and Tanya Harrison, the director of science strategy for Planet...

Florida Today After a seven-month, 300-million-mile journey to the Red Planet, NASAs Perseverance rover has sent back the first high-definition color pictures of Mars, including a selfie. On Friday, NASA released a photo of the rover in mid-descent as it was suspended under the sky crane moments before it touched down on the Martian surface. “This is something that we’ve never seen before. It was stunning. The team was awestruck. Just a feeling of victory that we were able to capture these,...

January 26, 2021 Earth has had at least 5 major ice ages. Now it appears Mars – the next planet outward from the sun – has undergone anywhere from half a dozen to 20 ice ages in the past several hundred million years. Glaciers below three craters in the Hellas Planitia region of Mars, now covered by rocky debris (left) and what they might look like if the ice was exposed (right). The image was created using image data from the Context Camera (CTX) on the Mars Reconnaissance Orbiter (MRO) s...

Copy link for An AI Has Discovered New Craters on Mars If youve ever played one of those "spot the difference between these two photos" games, you have something in common with NASA scientists. To identify newly formed craters on Mars, theyll spend about 40 minutes analyzing a single photo of the Martian surface taken by the Context Camera on NASAs Mars Reconnaissance Orbiter (MRO), looking for a dark patch that wasnt in earlier photos of the same location. If a scientist spots the signs of...

Using data from the Context Camera aboard NASA’s Mars Reconnaissance Orbiter, planetary researchers have generated an 8-trillion-pixel global map of Mars and performed the first systematic global survey of Martian fluvial (river) ridges. This image shows a suite of fluvial ridges on Mars (at –67.64 °E, 43.37 °S). Image credit: J. Dickson. Mars used to be a wet world, as evidenced by rock records of lakes, rivers, and glaciers. The Martian river ridges were formed between 4 and 3 billion y...
