Comet Siding Spring's October Encounter with Mars Will Create 30 Minutes of Concern for Global Space Agencies

On October 19, 2014, at 18:32 UTC, Comet Siding Spring (2013A1) will pass Mars at roughly 150,000 kilometers, about 1/3 the distance between Earth and the Moon, in a direction putting it on a track for its dust to pass over the Martian North Pole, possibly endangering, over a thirty minute window, the collection of orbital spacecraft currently on station in that region.

Comet 67P/Churyumov-Gerasimenko Revealed

This week's images of comet 67P/Churyumov-Gerasimenko reveal an extraordinarily irregular shape. We had hints of that in last week's images and in the unscheduled previews that were seen a few days ago, and in that short time it has become clear that this is no ordinary comet.
