Serene state of mind

New Horizons spacecraft's arrival at the next destination is upcoming New Year's Day.
Even though it's impossible to observe the target thoroughly like Hayabusa2,
From various articles after New Horizons' Pluto flyby, I understand that we can discover various things just from surface images.
I also wish good luck on Hayabusa2.
Both are on important mission to explore the origin of Solar System.
I wonder whether New Horizons is taking "Pale Blue Dot" after it completes upcoming mission, from farther than Voyager 1.
When I was a junior high school student, I was deeply interested in space exploration,
Especially I was bit with Voyager programs, but backed down after I flunked in mathematics in high school.
The trigger I came back in spring 2015 was New Horizons.
Then I came to be able to read website of NASA and Voyager program, and I came back in full swing.
So I suppose I ought to see out Voyager programs until both of them use up electricity and send final contacts to Earth.



Since I read the news on Oct. 5 that Voyager 2 is sending data showing that it's nearing Interstellar space,
I've wondered when it's reaching the edge of the Solar System.
If my memory serves me right, when Voyager 1 entered Interstellar space in Aug. 2012, the location was about 18.3 or 18.5 billion kilometers from the Sun.
As of Dec. 1, 2018, Voyager 2 was about 17.8 billion kilometers from the Sun.
Then, with a quick bit of math, it has 500 or 700 million kilometers to go to reach the edge of the Solar System.
-While I was thinking of such things, situation changed:
Voyager 2 turned out to reach Interstellar space on Nov. 5, and it became a spacecraft that visited four planets and entered Interstellar space.
At last! Congratulations!
Incidentally, as of Dec. 10, Voyager 1 was about 21.5 billion kilometers from the Sun.
Can anybody see the moment the flight distance meter of Voyager 1 on website of JPL indicating 22,222,222,222km!?
Keep going, deserving the name!
