Today's 2 topics:

- NASA's Deep Space Network is celebrating its 50th birthday. Australia, Spain, and California host its three sites. These facilities are spaced nearly evenly around the world to provide continuous communication with any spacecraft.

- NASA's Hubble Space Telescope was used to study 3 planets orbiting stars similar to our Sun. These data provide direct evidence of the amount of water which is present on each planet.
