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 have to admit a bit of surprise at the quality. Are these images actually circular rather than rectangular? And can we expect those drop outs (?) as the "norm"?

Are these images actually circular rather than rectangular? Not sure what you mean by this. QUOTE And can we expect those drop outs (?) as the "norm"? Did you actually read the caption? "The dark vertical streaks at the top of the image are caused by short exposure times (less than three milliseconds). Short exposure times are required for imaging an object as bright as Earth, but are not anticipated for an object as dark as the asteroid Bennu, which the camera was designed to image." That said, I'm not sure why short exposure times would cause streaking like that -- maybe blooming from the horizontal register? -------------------- Disclaimer: This post is based on public information only.

Not sure what you mean by this. I'd guess the jagged limb Earth displays indicating this is an orthographic projection (due to noticeable s/c motion or whatever) instead of a straight-up RGB composite. -------------------- |
