The European Space Agency has captured a stunning image of a 30 km-wide impact crater hidden within a landscape of winding channels, similar to the veins running through a human eyeball. These channels most likely have transported liquid water across the surface of Mars around 3.5–4 billion years ago.
These channels also appear to be partly filled with a dark material, with some places raised above the surrounding land. What might have caused this? Possibly erosion-resistant sediment that settled at the bottom of the channels when water flowed through them, or they were caused by flowing lava later on in Mars’ history. Then we have Mojo Vision’s augmented reality contact lenses making headlines here.

Aonia Terra is named after a feature called Aonia, a dark patch on the surface of Mars that can be seen from Earth, even with rudimentary telescopes. Aonia was also a region in ancient Greece, a location sacred to the Muses, the goddesses of literature, science and the arts,” said the ESA.
