Twitter is a free social networking and micro-blogging service that allows users to send “updates” (or “tweets”; text-based posts, up to 140 characters long) to the Twitter website, via short message service (SMS), instant messaging, or a third-party application such as Twitterrific or Facebook.

This quote from Wikipedia is just in case you are so disconnected to the real / Internet world that you don’t know what Twitter is 🙂

I’m happy to share with you one of my new Twitter Friends: Phoenix.

Phoenix is the newest Mars Exploration Rover, just landed on the surface of Mars with two objectives:

  1. Study the History of Water in All its Phases
  2. Search for Evidence of Habitable Zone and Assess the Biological Potential of the Ice-Soil Boundary

He twitts often and will twitt a lot (at least) in the next 90 days as ‘he is too excited to slip’

Really nice use of micro blogging!
