Wow - great work, I'm impressed. Some of the scenes seem to stand still though, the objects perceived as stopped due to the lack of moving background. And the speed of the probe through the sun seems unrealistic, given how fast it was travelling before and after. I found the ending self-destruct sort of abrupt. Could use some minor tweaks here and there, but overall quite good. File size seems unrealistic for a lower quality movie of this length. Perhaps try encoding it in something other than quicktime.
