MEXICO: The Voyager 1 spacecraft, that left Earth on 5th September, 1977, has now left our solar system and entered interstellar space. This is our last chance to send a message to aliens via the spacecraft, explaining how our society has changed over the past 38 years.
What is interstellar space? According to NASA, scientists say the beginning of interstellar space is the place where the sun’s constant flow of material and magnetic field stops influencing its surroundings, i.e. the heliopause. It marks the end of a region created by our Sun that is called the heliosphere.
Voyager 1 has just left our heliosphere – the first spacecraft from Earth ever to enter interstellar space. In a few years, Voyager 1 will lose power and we will not be able to communicate with it any more.
Facebook has started a Voyager’s Final Message campaign to record one last message before the spacecraft shuts down.
The campaigners suggested we could send the following message:
“Over 40 years after leaving Earth this spacecraft named Voyager had broken into interstellar space, 20 billion kilometers from its home planet, & was still powered & collecting useful data.”
