The capsule began its return to Japan a few moments ago as I write this. Seems like a good time to start a new topic for the much-anticipated final results of this epic mission.
-------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

Short Aviation Week article today. Highlight: It may take up to six months to determine if the capsule contains any material from Itokawa.

Short Aviation Week article today. Highlight: It may take up to six months to determine if the capsule contains any material from Itokawa. The Asahi Shimun newspaper carried an article today. Gists of what it said are as follows. 1. JAXA had placed equal priorities on finding the capsule and the heat shield. 2. Neither NASA nor ESA had been willing to discuss details of heat shields for potential millitary uses. 3. The capsule was found 1.1 km away from the targeted landing position and the heat shield 5 km away from it. 4. The ablator material was found to have been evenly melted and enough thickess of it still existed. 5. Initial investigation did not find partciles larger than 1 mm, and their minimum expectation is 0.003 mm. 6. Innner container (sampling container) was extracted and showered by shots of dry ice and then plasma cleaned so that a thin layer was removed. 7. The inner container will be brought into a clean room and tilted so that a rubber spatuler can scrape out (seems rather primitive to me) what may be inside. What are found will be treated with a thin needle with static electricity under microscope. 8. If there are lots of them then they will know immediately that they are from Itokawa. However, if there are only a few, 9. It will take up to 6 months to determine that they are not of Earth origin. 10. Samples, if any are found, will be distributed to 10 universities across the world. This last one, it differes from the info I got earlier. Mt earlier info said "best proposals from worldover". Who is telling the truth... Pandaneko |

The Asahi Shimun newspaper carried an article today. Gists of what it said are as follows. 6. Innner container (sampling container) was extracted and showered by shots of dry ice and then plasma cleaned so that a thin outer layer was removed. 7. The inner container will be brought into a clean room and tilted so that a rubber spatuler can scrape out (seems rather primitive to me) what may be inside. What are found will be treated with a thin needle with static electricity under microscope. Pandaneko I have had a look at JAXA English web pages prior to this posting and there is not this one yet carried. The inner container was being opened today (24 June, JST) at ISAS in the presence of NASA and other overseas scientists. It will take one week to find out what may be inside the container. I cannot wait to hear what they have to say! What was it like when the Earth was born! [please review section 1.3 - Admin ] Pandaneko |

I cannot wait to hear what they have to say! What was it like when the Earth was born! [please review section 1.3 - Admin ] Pandaneko OK, understood, reference to that sort of things either, not even as a joke. It is a bit difficult for me to make judgements about what I could post now as I would have thought that everybody would think that references to organic materials can easily lead to such jokes. My strong impression is that you wanted to further clarify to me just how rules are meant to be used for judgements in the strictest sense. (I am not supposed to use such a word, here even in response, that is my understanding...). However, seriously, I think your attitude must be absolutely right, after I have given my very deepest thought to this reason. That is, logically, so, apologies once again! There was a reference to organic materials in the same article I quoted and I must admit that it is my ignorance about such materials. I just did not think that there could possibly be organic materials on such a tiny body like Itokawa in near vacuum out in deep space in such cold temperatures. That is why I just ignored to translate that bit, perhaps I should have ... I should imagine, though, that a lot of other lay people may have such an association and connection, on hearing about the possibility of organic materials, i.e. commmon viewers to your forum. And, they may well like light jokes..., occasionally, am not sure... To me, being a physicist, organic materials simply means things like beef stake, eggs, fish and the like! I also think in terms of the real possibility of my joke sparkling off an endless discussions of the sort you fear. Given the seriousness of the forum I myself would think that there is very little chance. However, you must have had your own past dealings of that sort and I respect your ultimate judgement. Anyway, I am likely to make similar mistakes in future. So, what follows is my last contribution and I hope that you will keep me as a watching member, if you could, please? If not, I will not be complaining, though. I came here just accidentally, after all... Today's Asahi Shimbun newspaper here, with local circulation of about 8 million, I believe (the largest daily circulation here is by another local newspaper group and it is 15 million, I think) carried an artcicle about the sample container (25 June, JST). The container did have a very small amount of gas in it and it was recovered. As far as I have checked out so far, there is no reporting about it yet on JAXA pages, either in Japanese or English. They think that most of it is of Earth origin upon landing and constituents are yet unknown. However, there is a possibility that some portion of it may have come from Itokawa grains and they are very carefully checking the gas. Pandaneko |
