Here’s the latest image of Comet 67P/Churyumov-Gerasimenko “Cherry-Gerry or just 67P” taken by ESA’s Rosetta spacecraft on August 1, 2014 at a distance of 621 miles (1,000 km). As you can see there’s much more detail in this image than the July 14 & the July 29 images which really shook things up for the Rosetta team.

The initial shock of a contact binary nucleus has now given way to an oddly shaped nucleus, roughly 4 x 3 kilometers, with two lobes or balls of mass with a thin connecting bridge between the two. Surface features are starting to reveal themselves as we can see topographical changes throughout its terrain as well as variations in the color of that terrain. This newly gleaned information we add to current data we’ve collected (6.45 year orbital period, 12.7 hour rotational period, perihelion on August 13, 2015 etc.) to better paint a picture of the current situation and every day review, preview and tweak the details of the mission as needed.

Either way, the discovery that 67P isn’t really spherical in any way has certainly made things interesting. When Rosetta enters into orbit this Wednesday, August 6, 2014 it will have to overcome yet another obstacle to reach the destination of success. However, after more than ten years of amazing achievements and firsts I have no reason to believe that this discovery and its subsequent challenges will prove to be too much for ESA and their resources.

As I said, Rosetta reaches 67P this Wednesday the 6th and landing of the 100 kg, 3 legged Philae lander onto the comet’s surface, is at this time scheduled for sometime in November 2014 where it then, along with the orbiting Rosetta, will ride the active comet around the sun on to a fate unknown.

If you are so inclined, here are the previous 2 posts I’ve created on this wildly fantastic mission:
