Mars vs. Comet in 2014: Preparing for Red Planet Sky Show [1]

Wunderground.com-4/1/13, Leonard Davis

A close encounter between Mars and Comet C/2013 A1 (Siding Spring) in 2014 is creating both opportunity and anxiety in scientific circles. Scientists are in the early stages of assembling a comet-watching campaign that uses a spacecraft currently orbiting the Red Planet, as well as rovers on the Martian surface.

Scientists are also investigating what techniques could be used to prevent cometary debris from hitting Mars-orbiting spacecraft as the comet and planet converge.

The Mars-bound comet [2] was discovered by Rob McNaught on Jan. 3 at Siding Spring Observatory in Australia. Scientists estimate that this comet arrived from our solar system’s distant Oort cloud and has been on a more than 1-million-year journey. The comet could contain volatile gases that short-period comets often lack due to their frequent returns to the sun’s neighborhood.
