Martian surface: icy, cold, and dry for 4 billion years
Maybe the warm and wet environment on early Mars that scientists have long proposed wasn’t at the surface, but rather buried in the crust. That’s one of the conclusions of a new review that looks at Martian clay minerals and … Continue reading
Can melting snow make small holes in Mars rocks?
Many rocks on the surface of Mars show pits and small holes. One way such pits can form is when gas-rich lava erupts; the pits, called “vesicles,” form when gas escapes from the lava as it’s cooling. Wind-driven sand can … Continue reading
