NASA’s rover captured a unique image on Mars of an Earth-like polar process.
NASA’s Mars Reconnaissance Orbiter (MRO) has been orbiting the red desert planet for a decade and a half, capturing numerous detailed images of volcanoes, valleys, dry lakes and much more on Mars.
NASA recently shared a fascinating new image from orbit that shows a unique crater on the planet’s surface.
The nearly 1km-wide crater, created after an impact long ago from an asteroid or comet, is filled with intricate, if not psychedelic, patterns. What happened was a very Earth-like process: Winds blowing the sand and soil created a variety of ripple-like patterns (known as wind-sediment ripples) on the crater floor.
As can be seen in the top right quadrant of this crater, ripples can also form on top of a flat-topped hill.
While the orbiters observed Mars from above, the robotic rovers roamed the Martian terrain below. Perseverance – NASA’s most high-tech rover – is looking for past signs of microbial life – which should have existed – in the lakebed and dry waterways of Mars, to solve answer the question of whether there is life on Mars.
