Humans are desperately seeking ways to extend our planet’s life and history, reproducing human in space, finding portals to other universes, or searching for earth-like planet. The truth is we might not be alone, right? Hello from earth is collecting messages that will be transmitted to Gliese 581d, a planet outside our Solar System which may support life.
After the final message has been collected on Sunday 23 August 2009, all the messages will be collected and exported as a text file and sent to NASA”S Jet Propulsion laboratory in California, where it will be encoded into binary code, packaged and tested before transmission.
The signal will reach the solar system of Gliese 581 around December 2029. Any response will need to travel the same way back, so unless Gliesans have improved communication technologies, the soonest we could hope to receive an answer would be in 42 years around 2051.
The chances are we will be hollering the question into the vastness of the universe for centuries to come. But that doesn’t mean that such cosmic calls are doomed to failure. In 1961, astronomer Frank Drake formulated an equation that predicted the likelihood of detecting other intelligent civilisations in our galaxy. In 2007, Drake told NASA’sAstrobiology Magazine that he estimates we’ll eventually find existing intelligent life in “one in ten million stars.”
