NASA's trusty rovers and you'll see some pretty stunning stuff, you can almost always tell me when you see them see one. The sky is almost always a hazy orange, and the wind looks and devoid of recognizable features.
One of the latest images sent back by the Curiosity rover does away with that
"NASA's Mars rover Curiosity has acquired this image using its Mars Hand Lens Imager (MAHLI), located on the turret at the end of the rover's robotic arm," NASA explains. The image was captured on March 24th.
There are a couple of interesting things to note about this photo. First, the tiny rocks are a pale off-white rather than a bold rusty orange like many other images we see the planet's surface. Mars' terrain has a lot of variation in terms of color and we'll get a chance to see that up-close like we can.
Secondly you'll notice smaller gray ball mixed in with the oblong pinkish pebbles.
NASA assures that it is not the case, and that it does not exist these "blueberries" as they are sometimes called are the result of a natural phenomenon called concretion. It's what happens when minerals begin to gather in water-soaked rocks, eventually hardening.
It is a very cool image and it serves as a great reminder that despite being separated by an incredible distance, Mars and Earth are actually very similar.
