10 Things You Probably Didn’t Know About NASA’s Voyager 2

NASA's Voyager 2 thoroughly examined Jupiter and its magnetosphere. Furthermore, it also discovered the 14th moon of the planet. 

NASA’s Voyager 1 and 2 are the only human-made objects that have gone far in the space. The Voyager 2 probe has recently left the heliosphere, a bubble of particles and magnetic fields created by the Sun. Moreover, its twin, Voyager 1, is heading toward the interstellar space.

NASA’s Voyager mission has helped numerous scientists all across the globe. Both probes have accumulated sufficient data for us to have an idea about the enormity of the space.

Following are ten interesting facts regarding NASA’s Voyager 2. Let’s have a look at them, shall we?

1) Voyager 2 was launched to study and investigate multiple planets:

NASA’s Voyager 2 was initially launched to investigate Jupiter, Saturn, Uranus, and Neptune. Majority of the pictures that we see on the internet are taken by NASA’s Voyager 2. Moreover, Voyager 2 shuttle was launched on August 20, 1977.

2) NASA’s Voyager 2 has crossed the outer edge of heliosphere:

Multiple scientists believe that the probe has crossed the external edge of the heliosphere. Moreover, Voyager 1 is travelling toward the interstellar space and is about to cross the boundary of our solar system.

3) Voyager 2 is pretty far from the Earth:

As per various reports, Voyager 2 is quite far from the Earth and is about to reach the boundary of our solar system. Mission supervisors at NASA can easily communicate with Voyager 1 and 2. However, it takes about 16.5 hours to receive one message from the depths of space.

4) Voyager 1 and 2 have not yet left the solar system: 

As per reports, Voyager 1 and 2 have not yet left the solar system. The edge of the solar system is considered to be beyond the boundary of the Oort Cloud. The width of the Oort Cloud is still unknown, but it will take approximately 300 years for Voyager 2 to enter the inner boundary of the Oort Cloud. 

5) Voyager 1 and 2 contain a Golden Record:

Both Voyager 1 and 2 carry the Voyager Golden Record, which is basically a recording of sounds and images of life on Earth. It was designed by experts to communicate with extraterrestrial life. Moreover, Voyager 2 crossed the heliosphere in around 2018. 

6) The Voyager shuttles are powered by radioactive material: 

Both of the Voyager probes are powered by radioactive material; they contain a device called (RTG) radioisotope thermal generator. NASA states that the power of RTGs drops by approximately four watts per year. Hence, multiple parts of the Voyager shuttles have turned off. The Voyager probes have travelled for decades without a camera. 

7) Voyager 1 and 2 have outlived their life spans:

NASA’s Voyager 2 was launched in 1977, 16 days before Voyager 1, and both have travelled past their original destinations. Both of the shuttles were built to last only five years. However, they have remained functional for approximately 41 years, making Voyager NASA’s longest-running mission.

8) The tales of Voyagers have impacted thousands of scientists all over the globe:

The story of NASA’s Voyager probes has influenced numerous future scientists and engineers. Multiple scientists are working on projects that could change the history of humankind.

9) NASA communicates with the Voyagers with the help of DSN (Deep Space Network):

NASA’s mission controllers interact with the probes with the help of DSN; it is a global method for communicating with interplanetary shuttles. The DSN has a set of antennas in California, Spain, and Australia.

10) Voyager 2 visited Jupiter and discovered its 14th moon:

NASA’s Voyager 2 thoroughly examined Jupiter and its magnetosphere. Furthermore, it also discovered the 14th moon of the planet.
