What is the difference between Voyager 1 and 2?
In Depth: Voyager 1. NASA’s Voyager 1 was launched after Voyager 2, but because of a faster route, it exited the asteroid belt earlier than its twin, having overtaken Voyager 2 on Dec. 15, 1977. It began its Jovian imaging mission in April 1978 when it was about 165 million miles (265 million kilometers) from the planet.
How long will Voyager 1 stay in the Solar System?
In August 2012, Voyager 1 became the first spacecraft to cross into interstellar space. However, if we define our solar system as the Sun and everything that primarily orbits the Sun, Voyager 1 will remain within the confines of the solar system until it emerges from the Oort cloud in another 14,000 to 28,000 years.
Why did Voyager 2 change course at Saturn?
Voyager 2 changed course at Saturn in order to fly by Uranus and Neptune, performing the only close flybys of those planets in history. The Voyager probes completed their Grand Tour of the planets and began their Interstellar Mission to reach the heliopause in 1989.
When did Voyager reach the heliopause?
The Voyager probes completed their Grand Tour of the planets and began their Interstellar Mission to reach the heliopause in 1989. Voyager 1, the faster of the two probes, is currently over 13.6 billion miles (22 billion kilometers) from the Sun, while Voyager 2 is 11.3 billion miles (18.2 billion kilometers) from the Sun.
How does Voyager 1’s distance from the Sun change?
Note: Because Earth moves around the sun faster than Voyager 1 is speeding away from the inner solar system, the distance between Earth and the spacecraft actually decreases at certain times of year. This is a real-time indicator of Voyagers’ straight-line distance from the sun in astronomical units (AU) and either miles (mi) or kilometers (km).
When did Voyager 1 go to interstellar space?
Launched in 1977 to fly by Jupiter and Saturn, Voyager 1 crossed into interstellar space in August 2012 and continues to collect data. Voyager 1 and its sister ship Voyager 2 have been flying longer than any other spacecraft in history.
What is the plasma that Voyager 1 is encountering?
The plasma that Voyager 1 is encountering was produced by our Sun, the researchers say. The solar wind that carries gasses for billions of miles is powerful enough to lead to the expulsion of plasma from our solar system.
