Voyager 1, the first man made Interstellar machine.

Featured Video Play Icon

On September 5, 1977 at 12:56:00 UTC, Voyager 1 began the most advanced human made machine exploration of all times, The space probe was placed on it’s travelling course by a Titan IIIe rocket, and as of right now, this is how far Voyager has traveled since it’s “Launch point in space and time”. Travelling at 10.725 miles per second (38,610 miles per hour).

(See JavaScript Snipped code below, how the odometer was programmed)

The mission objectives was a flyby of Jupiter, Saturn, including it’s large moon Titan, on November 20, 1980, Voyager 1 headed to the boundaries of the heliosphere.

Heliosphere - Heliopause

Heliosphere – Heliopause

The heliosphere is a region of space influenced by the sun, which extends beyond the orbit of Pluto, the heliosphere is a bubble shaped boundary maintained by solar wind (plasma) out from the sun.

On August 25, 2012, Voyager 1 crossed the “heliopause”, which can be interpreted as “the walls” of the heliosphere, and by crossing this point in space, Voyager 1 was the first ever man made “interstellar machine” to travel outside of our solar system.

Humans by nature are explorers, but we get so occupied with our lives that most of us don’t credit such unique events, this is very big for humans in the universe … (modestly in the Milky Way). We are for the first time navigating on uncharted space (at least uncharted for humans for sure), on a selfishness trip that many of our future generations will be enjoying (until Voyager 1 can no longer transmit signals back to Earth).



NASA placed information from Earth on Voyager 1 cargo, in the form of a golden disk, that contains sounds from our planet, such as a child crying, whales, music, images, different languages, the voice of “Nick Sagan” the son of “Carl Sagan” saying: “Hello from the children of planet Earth” , and “Janet Sternberg” with a message in Portuguese: “Paz e felicidade a todos” (Peace and happiness for all).

Lets not forget the team that took the task to represent all of us in the universe by making this astonishing machine to reach far beyond our individual lifetime, a human made machine breaking all records, every second of or lives , wondering in future billion miles travel.

You can tell I am a fan, (I surely am) … I also recognize the importance of NASA in our lives  🙂
