Methane in a flash
Martian methane is a hot topic because of its potential origin in biological, as well as geological processes. Observations (Earth-based and from Mars orbit) have found only a small quantity of the greenhouse gas in the atmosphere of Mars — … Continue reading

More dust devilry in the air
Dust devils are the most dynamic feature on Mars, and scientists are zeroing in on how they work. An earlier Red Planet Report described dust devil motions as mapped by fortuitous simultaneous observations by cameras on two separate spacecraft. Now, … Continue reading
Devilry in the air
