Meteors at Mars!
 
Comet dust did hit Mars!  On Oct 19th, comet Siding Spring made its extremely close flyby of Mars, passing a mere 140,000 km from the planet.  But after the flyby, the comet's dust trail got even closer; close enough to make a meteor shower.  No direct observations of meteors have been reported, but indirect results from the MAVEN and Mars Express spacecraft suggest 1000 kg of material was deposited into the atmosphere.  That sounds like a lot, but to a planet, it is nothing.  Tony Farnham of the University of Maryland explains why, and how the encounter was pretty close to what we expected.

carbon dioxide be crazy
 
Year In The Life Of Earth's Carbon Dioxide

In this simulation of the global atmosphere, higher concentrations of carbon dioxide are shown in red and orange. Notice how plumes of carbon dioxide swirl and shift as winds disperse the greenhouse gas away from its sources, which includes fires and fossil fuel burning. The simulation also illustrates differences in carbon dioxide levels in the northern and southern hemispheres and distinct swings in global carbon dioxide concentrations as the growth cycle of plants and trees changes with the seasons. The carbon dioxide visualization was produced by a computer model called GEOS-5, created by scientists at NASA Goddard Space Flight Center’s Global Modeling and Assimilation Office. “While the presence of carbon dioxide has dramatic global consequences, it’s fascinating to see how local emission sources and weather systems produce gradients of its concentration on a very regional scale,” said Bill Putman, lead scientist on the project from NASA's Goddard Space Flight Center in Greenbelt, Maryland. “Simulations like this, combined with data from observations, will help improve our understanding of both human emissions of carbon dioxide and natural fluxes across the globe.”
