ScienceBlogs: Does Dark Matter affect the motion of the Solar System?  

I especially like the author's story about how HE actually examined this problem utilizing many of the techniques for examining questions that I like to explore in this blog.  Also note the graphic comparing some of the galaxy surveys with the Millennium cosmology simulation (Wikipedia).  If you didn't know it was a simulation, could you distinguish it from the actual datasets presented?

Celestial Billiards for Space Travel

Ever wonder how the flight dynamicists at NASA and ESA develop some of the complex trajectories which can take a satellite from Earth to some distant location (like Jupiter or Saturn) using gravity assists?  They're currently developed guided by some rules-of-thumb which are refined with detailed n-body simulations.  But Artificial Intelligence systems (AI) are catching up in this capability.
