Voyager one is the first spacecraft to leave the solar system. Voyager one launched on September 5, 1977. Voyager 1 job was to explore the planets farthest away from the blue planet. The man in focus being Jupiter and Saturn.
Voyager 1 exceeded its expectations by leaving the Solar System.
Voyager one was able to leave the Solar System in quite a short period of time because the spacecraft has been traveling along different flight paths.
Essentially, Voyager one was launched to take advantage of the alignment of the outer planets. Every 176 years, the planets in the solar system aline. This is the reason NASA launched Voyager 1 when they did.
The alinement of the planets allowed the spacecraft to be rubber-banded from planet to planet, to build speed and conserve energy.
How does voyager one communicate
Currently, 14,100,000,000 miles away from the Earth as of January 12, 2020. Voyager one hasn’t lost communication with the Earth because it uses DSN (Deep space network). DSN is a series of giant radio antennas on Earth that detect waves. To help you understand how these waves work you should know that it takes 15 minutes to communicate with a Rover on Mars. But it takes 20 hours to communicate with Voyager one.
When will Voyager one Die
Voyager one will stop supplying data in 2025, and in 8 years Voyager one will run out of power.
Voyager one is nuclear powered & every day the electrical power weakens. Today only 4 of the 11 instruments are still active.
Now, voyager one is studying magnetic fields, solar winds, and cosmic rays.
