Comet Siding Spring: Risk Assessment

Karl Battams • August 07, 2014 • 6

On October 19, 2014, Comet Siding Spring is going to have an extremely close encounter with the planet Mars. The bottom line: it seems most likely that our Martian spacecraft will be absolutely fine.

A new comet observing campaign for C/2013 A1 (Siding Spring)

You thought you were rid of us...but we're back! Following the spectacular and, quite frankly unprecedented, success of the Comet ISON Observing Campaign, we are launching a similar venture for another unique cometary encounter that's happening this year. In October 2014, comet C/2013 A1 (Siding Spring) will pass extremely close to Mars.

Except it didn't. Well, maybe...

We're now less than two weeks away from comet C/2012 S1 (ISON) reaching perihelion and, if we’re honest, we are still none the wiser as to how the situation might play out!
