In 1977, NASA launched two spaceships that might change our understanding of the universe: Voyager 1 and Voyager 2. These spaceships were designed to look at the external planets of our solar system and supply critical data on their conditions.
What’s more, they set off on a rare journey from Earth, aside from the influence of the sun, and have become the primary human objects that left our solar system.
Voyager 1, introduced to the market on September 5, 1977, is currently probably the most famous of the land produced by man, over 19.7 billion kilometers from August 1, 2015. Both Voyager 1 and Voyager 2 have now entered the interstellar space, continuing their journey to space. But what makes the Voyager mission so unusual?
What is Voyager?
Voyager 1 and Voyager 2 is a NASA spacecraft sent to look at the external planets of our Solar System, Jupiter, Saturn, Uranus and Neptune. In particular, Voyager 1 became the primary human object that broke the external boundaries of the solar system, exceeding Heliosheath, a region that sets the limit of the influence of the sun.
Introduced to the market in 1977, Voyager 1 is now removed from Earth, and Voyager 2, launched a month earlier, can also be heading towards interstellar space, even though it is a bit closer than Voyager 1.
Although their missions were almost similar, each spaceships contributed greatly to our understanding of the Solar System and the conditions of space far beyond
Voyager mission and goal
The basic mission of Voyager 1 was visiting Jupiter and Saturn, including their rings and moons. At the turn of the seventies and 80s, Voyager 1 sent the primary very detailed images of those giant planets.
These paintings provided deeper insight into gas giants and their unique features, resembling the attractive Saturn rings and the mysterious moons of Jupiter.
Although the foremost goal of the mission was external planets, Voyager also had a broader goal: to be the primary human object that traveled outside our solar system.
This ambition is reflected within the gold record transferred by each Voyager, geared toward informing about potential extraterrestrial civilizations about life on earth.
Golden Record: Message to the Stars
One of probably the most iconic facets of the Voyager mission is Golden Record, a gold -plated copper disk containing sounds and pictures representing life on Earth. The record was created as a message for all aliens which will encounter a spaceship in the longer term.
Golden Record, led by the famous astronomer of Carl Sagan, includes:
- 115 photos depicting landscapes, people and wildlife.
- Earth sounds, including greetings in 55 languages, music from different cultures and natural sounds resembling thunder and ocean waves.
The golden record serves as a peaceful message, depicting our world to a wider universe.
Voyager achievements
Despite the proven fact that they were launched over 4 a long time ago, Voyager 1 and Voyager 2 still reach groundbreaking milestones in space exploration. Voyager 1 has a record because the furthest human object from the bottom.
On August 1, 2015, he reached a distance of 19.7 billion kilometers and continues to go away. In 2012, Voyager 1 officially crossed the border of our solar system and entered the interstellar space, marking certainly one of the best achievements within the history of space exploration.
Voyager 2, although slower, made a big contribution, mapping the external planets of our solar system. In addition, Voyager 2 stays the one spacecraft that visited all 4 external planets, Jupiter, Saturn, Uranus and Neptune.
Voyager influence on space exploration
Voyager missions not only expanded our knowledge concerning the solar system, but additionally paved the way in which for further exploration of space.
Data sent by each spaceships still provide invaluable insight into the environment of space far beyond the reach of the sun, revealing many things previously unknown to scientists.
In addition, the golden record stays a logo of the need of humanity to achieve other civilizations within the universe. Although it just isn’t certain whether you ever enroll, he hopes that someday life on earth can be remembered, even by beings from distant galaxies.
Voyager heritage
Like Voyager 1 and Voyager 2, they proceed their journey away from Earth, carry an unusual heritage. Not only were they a pioneer of space exploration, but additionally symbolize the spirit of the journey and desire of humanity to know the broader universe.
Although the information they send change into rarer on account of the restrictions of power, their impact can be a milestone in achieving scientific knowledge.
