Saw this news article today:
http://news.nationalgeographic.com/news/20...th-osiris-rq36/ And didn't see a thread on this mission. There was a passing reference or two to it, and a mention here: http://www.unmannedspaceflight.com/index.p...310#entry161310 Of this: http://futureplanets.blogspot.com/search/l...roid%20Proposal Which I guess I missed on vjkane's blog. |

I guess this is what Hungry's referring to - this is a gamma-tweaked crop:
You can see that it looks like the image was masked to black outside a circle. It's noticable at the top of the frame because the mask follows the true edge of the Earth which is in shadow there (the phase is slightly gibbous) rather than the visible limb. Presumably this was done to get rid of some noise in the black regions. Hopefully they didn't mask out too much of the bright limb, but the bright limb looks too sharp (ie it looks aliased) rather than PSF-y as you'd expect... |
