HiRISE: Blockfall on north polar layered deposits
The north polar layered deposits (NPLD) are a stack of layers of ice and dust at the North Pole of Mars. The layers are thought to have been deposited over millions of years, as the atmosphere changed in response to … Continue reading

Habitable environments at Arsia Mons?
Arsia Mons is one of the giant volcanos of Tharsis — Mars’ third tallest, in fact. During past cycles of climate change, it accumulated a large fan-shaped deposit of glacial ice on its northwest flank. (The other tall Tharsis volcanos … Continue reading
HiRISE: What gullies can say
Right past the sharp, but warped rim of this ancient impact crater are deposits of winter frost, which show up as blue in enhanced color. There are two possible science goals that we can study here: what does the terrain…. … Continue reading
