Voyager 1 and 2 Turn 40


Richard Berrebbi works as a partner at American Healing Technologies, Inc., a B2B traditional Chinese medicine importer and distributor. There, he leverages his international partnerships to source the highest quality Chinese herbs. Outside of Rich Berrebbi’s professional life, he has a keen interest in astronomy. 

On September 5th, the Voyager 1 spacecraft turned 40 years old, having launched on the same date in 1977, just weeks after the launch of the Voyager 2 craft. The Voyager 1 craft is currently the farthest human spacecraft from earth. As of September 1st, it was a staggering 12.97 billion miles away, over 139 times farther than the distance between the Earth and the sun. 

Back in 2012, Voyager 1 became the first human spacecraft to leave our galaxy and enter interstellar space. Voyager 2 is expected to follow suit within the next few years. While Voyager 1 feeds NASA never-before-seen data regarding the effects of solar wind far from Earth, Voyager 2 is busy learning about the conditions on the edge of the solar system. 

According to Ed Stone, a Voyager scientist who has been working on the project since before either craft launched, says the both Voyager 1 and Voyager 2 still roughly 10 years of power left in them before the instruments become useless. Provided they do not collide with other objects, the two craft will continue flying after losing power, traveling once around the Milky Way galaxy every 225 million years.
