"Twitter wasn't built to give voice to Curiosity, the rover currently exploring Mars, but it's awfully well-suited for the purpose.
One of the risks of science experiments taking place on other planets, after all, is that people lose track of them. We forget they're up there. We know they're doing something, but we don't really remember day to day all the things that the engineers and scientists are trying to do with them, and when they come home, absent some major piece of news ('Our rover has discovered 8-track tapes on Mars!'), it almost seems like nothing happened. It brings new meaning to the phrase 'out of sight, out of mind.'
Enter @MarsCuriosity, the Twitter feed that is, as of this writing, followed by almost 1.1 million people. As Morning Edition discussed a couple of weeks ago, Curiosity's feed is run by three women who work in the Jet Propulsion Laboratory in Pasadena. Stephanie Smith is one of them, and says of Curiosity in that report, 'Thinking about her as the most advanced, biggest, most complex robot Earth has ever sent to the surface of another planet, and she's got a rock-vaporizing laser on her head, I think she's got some well-earned bravada.'"
