Mars Phoenix Speaks

NASA has been posting first person accounts of the Mars Phoenix lander's mission via Twitter for some time now. It's basically the only reason why I got a Twitter account—in order to follow Phoenix. It's cool and sometimes even poignant to receive these little messages from Mars. Now, nearing the end of its life, the Phoenix Lander saying goodbye as a "guest blogger" on Gizmodo.

Now another NASA mission, New Horizons is jumping on the Twitter bandwagon as it makes its way to Pluto. If nothing else, it seems like a great way to get young people interested in science.
