Today's 2 topics:

- Imagine holding a rock as old as our solar system that has traveled billions of miles through space to reach its present location.

- Asteroid 2011 MD's mass and size make it a good candidate for NASA's plans to use a robotic space craft to intercept and redirect a small asteroid into an orbit around our Moon.
