Rosetta’s Goal

Here is an image of comet 67P/Churyumov–Gerasimenko taken on 05 Oct 2013. This is the comet ESA’s Rosetta spacecraft is destined to orbit. As far as I know this is the latest image of the comet.

The image was taken by the Very Large Telescope (VLT) at the European Southern Observatory (ESO) in Chile. We can see the comet with and without the background of stars.

The comet was about 500,000 km from Earth and heading behind the Sun from our perspective in its six and a half year orbit at the time. If you have about 15 minutes or so, I’d like to encourage you to visit ESA’s “Where is Rosetta“. This was fantastic look at Rosetta’s journey and gives a nice perspective into how much planning goes into a mission like this.

If you watch it from the begining, you will notice around late 2010 or early 2011 both the comet and Rosetta go “off screen”, click the “reset view” to zoom out to see it. I would suggest not hitting that link until then though as early on the orbits by Rosetta are pretty interesting as far as how the mission was set up to put the spacecaft in position to chase down Churyumov–Gerasimenko — it loses its flair zoomed out.

You can also move the slider along the time line if you are in a hurry.

One thought on “Rosetta’s Goal

  1. Great post Tom. ESA’s done a great job on that website. I can hardly wait till November for the lander. I do hope that there is ice on it so that the lander’s harpoons can get a grip. I have been checking out the “Electric Universe” theories lately, and am looking forward to seeing if the comet is in fact made mostly of water ice, or is it mostly rock?
