A crumbly comet…

With less than two weeks to go until Philae lands, more ROSETTA images have been released by ESA, this time of the large, flat “plain” on the base of the comet’s larger lobe…

…and stitched together they show a fascinating variety of features and structures on 67P’s surface…

This is one of the areas of the surface the ROSETTA team will be watching most closely, I think, because there are lots of small and medium-sized features here which might change in appearance as the comet warms up; more of the boulders might be revealed as the icy material around and beneath them sublimates away, and the features drawn on the surface of the plain (come ON, ROSETTA team! Let’s have some names!!!!!) might alter in appearance too. In fact, if you enhance that ESA mosaic you can see a *lot* of detail and structure on that plain, hinting at structures beneath the dusty surface, waiting to be revealed in the weeks and months ahead…

Just as fascinating are what appear to be spills of brighter material on the comet’s surface…

Before we finish this post, let’s go on a whirlwind tour of some of the places and features shown on these images…

  2. Rosetta mission – Information gathering and techniques

    In a complex enviroment it always makes sense to go to the primary source for information gathering.

    Since the OSIRIS Instrument is managed by Max-Plank Gesellschaft (MPG), division Max-Plank Institute for Solar System Science (MPS). MPS houses OSIRIS experiment managed by Holger Sirks with an 80 member task force.

    ‚Next door‘ the press people are working – right as hard as the OSIRIS team. They are

    I visited the MPS home page on Sat. 1.Nov. 2014 21:16 cet

    Their latest press release is dated 23rd October 2014

    Thanks MPS for the fortnightly updates – with some bits
    of information too!

    Here is an alternative :
    You might as well call or write to the OSIRIS PRINCIPAL INVESTIGATOR

    (be prepared that he might read your mail in about six month – and avoid to expect an answer)

    I noticed that you erased my commnet on this page this morning.

    Would you aggree that this is nothing short of the submission ESA Blog Authorities demand and enforce?

    • All of a sudden my comment in question reappears
      Sorry Stuart excuse me for my bitter comment .

    • WHAT??? “Submission”?? Are you having a laugh? After all the criticism I’ve posted?

      WordPress behaves oddly sometimes. I don’t delete **ANYTHING**. I don’t have time to. I just let people post comments without comments of my own. You don’t have to come here if you don’t want to.

      And for the record, the ESA bloggers are doing a brilliant job, I think, bearing in mind the material they have to work with. They’re being severely hobbled by the lack of OSIRIS images, which is a continuing disgrace and nothing less than a snarling two-fingered F**K YOU!!! from the OSIRIS PI and those of his team unwilling to share the wonders they are seeing.
