Any news on if the drill managed to pick up anything useful? Curious to find out if the Ptolemy data that came back was of anything useful (as I understand it, Ptolemy's task was to measure isotope ratios so that we could see if the water composition on the comet was at all similar to that on Earth).

I hear some of the instruments were owned by private research institutes rather than European taxpayers (who funded the vehicle) so for some areas may take a while to publish. Might have to wait for proper papers etc

  Ptolemy's PI is Ian Wright at the Open University: http://www.open.ac.uk/science/pssri/research/missions/rosetta/ptolomy.php http://www.open.ac.uk/science/pssri/research/missions/rosett... But your point stands; I know a lot's under embargo right now, I was more wondering if we knew if the drill had successfully retrieved a bit of comet or not rather than specific experimental results which will take some time!

Might have to wait for proper papers etc It is not immediately obvious to me why who owns the instrumentation would be a driving factor in the time to see results. Both private research institutes and public institutes would want to get results out as quickly as possible, to capitalize on the PR effect. But that is moderated by the need to perform sufficienly accurate and detailed analysis, which takes time. Those pressures are the same for both public and private research institutes. If anything, the private institues would feel more pressure to publish results quickly, to improve their chances of obtaining future funding. I cannot tell if you are comparing the quickness of this press release with the lack of results from the scientific packages on Phile, but I will address the (potential) comparison, just in case... Part of reason this press release (with the image of Philae bouncing) was out so quickly is that it does not require a very detailed and specific analysis (requiring roughly the equivalenth of image stictching in photoshop), and the results are fairly straightforward. Additionally, it is not really providing much in the way of new scientific information and so does not have as high a burden of proof. Additionally, the OSIRIS imager has been used to collect data for a while now, so presumably the OSIRIS team has a decent understanding of the real-world operation of the equipment, enabling them to quickly release images in which they were confident. In contrast, the Philae lander's instruments had not provided actual data before the landing, so the instrument teams still need to do the careful calibrations and analysis to understand the systematics.

The drill probably not (no results for COSAC): https://twitter.com/erichand/status/534413817040867328 https://twitter.com/erichand/status/534413817040867328 They might have had some results from particles/gases in the atmosphere, not sure, nothing announced yet that I know of but they did say they were taking measurements. It might be weeks/months before they announce results.
