E.T are you out there? is a campaign of "Faces from Earth" project to introduce the concept of possible extraterrestrial life and interstellar messages to school students. The campaign introduced the questions to students: "what if there is extraterrestrial life out there?, what would we say to a hypothetical E.T.?". Thinking about these questions leads naturally to consider topics like sensitive communication, self-reflection, responsible preparation and handling of encounters by adults and students.
It was participated by school student groups in five countries; Hungary, Germany, South Africa, Sri Lanka and Ukraine during May 2010. Each of the groups started with an introduction to past space probe messages – the Pioneer Plaque and the Voyager Golden Record -, radio transmissions (Arecibo Message, Cosmic Calls, Teen Age Message, ...). At the end of the activity, each student/group created a “constructed message” for E.T. Some of the groups released completed messages with helium balloons as a message in a bottle.
