Robot Twitter feeds

Just as your X-Box 360 could secretly be blogging, NASA's robots, probes, and rovers love the internet. Here are some Twitter feeds of unfeeling machines exploring space:

Phoenix Mars Lander: Maybe the first Twitter to make blog headlines with its discovery of water on Mars, the Phoenix Mars Lander is already a staaar on the internwobs.

New Horizons: The Pluto-Kuiper Belt Mission is keeping us updated on when NASA posts mission updates, but it also gives you some interesting and fun facts about its destination. Hopefully there is enough trivia to keep it updated until it reaches Pluto in 2015.

NASA SDO HMI: Here is it's own description -- "I am the HMI instrument on board NASA's Solar Dynamics Observatory. I am a product of Lockheed & Stanford University. Look how sleek I am!" I feel like that's all I really need to say.

Cassini-Huygens: The Cassini-Huygens mission to Saturn and Titan has been gathering information and photos of Saturn's moons. The feed might be the least romanticized, but it updates with awesome fly-by pictures.

So uh, add all these dudes on Twitter! Space!
