Yes, you read that one right. In a stroke of marketing genius, NASA, beginning with the Mars Phoenix Lander (@marsphoenix), began to "ghost tweet" as if various mission robots were speaking with their followers. Not only was it a clever way to keep people interested and informed about NASA and space exploration, but it created some unusual and unexpected results. Followers became attached to the Mars Phoenix Lander and humanized it, perhaps partially due to the smash hit film "Wall-E," the Pixar computer animated film about a very emotional robot. The sad news is that the Mars Phoenix Lander's job required it to stay on the red planet forever. The 38,000-plus followers of Mars Phoenix were saddened, though the ghost tweeters tried their best to keep spirits up:
"I should stay well-preserved in this cold. I'll be humankind's monument here for centuries, eons, until future explorers come for me."
And the final message from Mars Phoenix was simply a structured series of ones and zeroes -- the binary code was translated as "triumph."
