JAXA wants to continue with Hayabusa 2. However there is/was a huge fight about the budget. Main problem was the budget for the launch vehicle. 2 months ago or so there was a report which said, that JAXA had to find another launch vehicle or the project gets cancelled. Now the Italian space agency played saviour and overed the VEGA. So finally we might see another Hayabusa in 2011.

It's great to see JAXA provide a chance to view then in such an open format!
The 'glitter' effect certainly gives them an otherworldly property. The colours are just camera artifacts from the light reflecting, right? (to the extent that any light reflects off such dark materials!) |

The colours are just camera artifacts from the light reflecting, right? (to the extent that any light reflects off such dark materials!) I also think they are amazingly beautiful and very much from different world - the most alien we currently possess! (from the unprocessed by the Earth's atmosphere - I mean not counting the meteorites). As for the colors, we have to remember that these are micrographs - these particles are actually tiny, and there is a lot of "color noise" - an artifact from the way the camera's color CCD image sensor works. This is clearly visible on the background surface next to the particles - especially in the shade. Therefore, at the smallest scale, the light points on the samples have „artificial” colors. These particles are almost monochromatic (like e.g. most lunar rocks) - almost black with lighter minerals (grayish white spots). But it seems to me that in general, on a larger scale, you can notice a slightly brownish shade - even slightly yellowish or reddish in places. Some places of the samples also seem to fall more into cool colors - grayish-bluish. But it might just be my subjective impression, an artifact resulting from lighting conditions or image compression! Only the spectra are objective Below: fragment of the original photograph with the background in shadow, and next to it with color saturated by me - the pattern of colors in a shaded background reflects the CCD sensor, I think. |
