40 days and counting. The long wait is almost over!
I wonder whether we will get enough data to test new simulation theories like this one. http://space.newscientist.com/article/mg19...solar-wind.html What do you expect from this first flyby? |

OK, a big sorry for my posts yesterday. I was up for 20 hours yesterday and 18 hours the day before on the Messenger encounter and other stuff. As I was putting a few messages on UMSF, I must have been delirious with the data rate stuff.
To clarify, it is kilobits but per second (not per hour). I was told that the inital link data rate was 25-30kilobits per second and passed that on as 'per hour' - - my bad. During downlink of the actual data we get a top rate of 104,166kb/s. Our coverage was from 0020-0720 UTC, so 7 hours of actual data downlink at nearly the top rate the entire pass. There was a 5 minute period where we were unable to get clean data due to a brief but severe storm. I hope that makes more sense. Glad I got some sleep last night. Looks like there might be a few more late nights though browsing through all these great images coming online. (sleepy) Astro0 |

Here's context for that crater image (was rotated 180 deg and contrast-enhanced):
EDIT: Added both new images. In the leftmost image in the above composite, notice how everywhere where the shadows are long, their edge is noticeably diffuse. No doubt a testament to the large angular size of the Sun there (3x as large as seen from Earth). I'm not sure you can see this in images of the Moon. -------------------- |
