In what has to be regarded as one of the most underreported milestones of all time the Voyager 1 space probe has reached the edge of the solar system and will be the first man made object to venture into true interstellar space. At roughly 18 billion kilometers from the sun and traveling at about 17 kilometers a second the probe has had quite a journey that has seen it and its twin Voyager II travel to all of the giant planets in our solar system along with some 48 of their moons. Launched in 1977 and powered by plutonium that will keep the probe sending data back to earth until 2025 it also carries a message for any intelligent life form to come across it. The message in the form of a gold plated phono graph with greetings from earth was designed by a group led by the famed scientist Carl Sagan. The probe is so far away from earth that the data it transmits takes over 16 hours to reach earth. I realize that since it is not a manned mission many will not pay much attention to this and that is a shame because this truly is one of the great achievements in space exploration. Think about it, who knows what it might find out there?
