Another Rosetta close-up of Comet 67P/C-G

My annual birthday-month fund-raising drive for Behind the Black is now on-going. Not only do your donations help pay my bills, they give me the freedom to speak honestly about science and culture, instead of being forced to write it as others demand.


Please consider donating by giving either a one-time contribution or a regular subscription, as outlined in the tip jar below.


Regular readers can support Behind The Black with a contribution via paypal:

Or with a subscription with regular donations from your Paypal or credit card account:

If Paypal doesn't work for you, you can support Behind The Black directly by sending your donation by check, payable to Robert Zimmerman, to

You can also support me by buying one of my books, as noted in the boxes interspersed throughout the webpage. And if you buy the books through the ebookit links, I get a larger cut and I get it sooner.

Close-up Comet 67P/C-G

Cool image time! As Rosetta completes a several weeks of in-close observations it took the above oblique view (cropped and reduced to show here) of Comet 67P/C-G. The image was taken from about 7.5 miles with a resolution of about 3 feet per pixel. It shows the Imhotep flat area with the large 80-foot-high Cheops boulder in the center. It is worthwhile to compare this image with one taken in January.. Though the angle is far different, you can recognize the same areas in Imhotep where some of the surface has apparently evaporated away.

What I especially like about today’s image is that it really gives one a feel for what it would be like to stand on the surface here. The light gravity allows some strange rock configurations, such as that giant weird balancing outcrop on the horizon. If you were standing in Imhotep that outcrop would hang above you threateningly.

The spacecraft is now moving away from the comet for the next few weeks

Following the brief encounter at these close distances, Rosetta is now heading out on an anti-sunward excursion to around 1000 km to investigate the comet’s wider coma, tail and plasma environment. Today, 24 March, Rosetta is already over 200 km away from the comet. The current plan is for Rosetta to make a 30 km zero phase flyby around 9 April, before entering back into closer bound orbits by 21 April.

    If people will download the hires jpeg of this picture
    open it with Irfanview
    select a section such as “the boulder”
    resize the section double x3
    and look at it they may be in for a surprise.
    “Strange rock formation” indeed.
    the Rosetta team were cute with their unembargoed Osiris NAC
    starting a week before the release of the new Star Wars
    which has a lot to do with space wreckage I am told.

  • Please note the last paragraph of my most recent post here. Make especial note of the last sentence.

    I think it is has everything to do with the comment above.
