It’s Official: Voyager 1 Is Now In
Interstellar Space (Universe Today Excerpt)
by Nancy Atkinson on September 12, 2013
Voyager 1 spacecraft is in
interstellar
space, the space between the stars,
and has left our Solar System. It actually made the transition about a year
ago.
“We made it!” said a smiling Dr. Ed Stone,
Voyager’s Project
Scientist for over 40 years,
speaking at a briefing today. “And we did it while we
still had enough power to send back data from this new region of space.”
While there is a bit of an
argument on the semantics of whether Voyager 1 is still inside or outside of
our Solar System (it is not farther out than the Oort Cloud — it will take 300 more years reach the Oort cloud and the spacecraft is closer to our Sun than any other star) the plasma
environment Voyager 1 now travels
through has definitely changed from what comes from our Sun to the plasma that
is present in the space between stars.
There’s also been a recent debate on if Voyager was really in or out of the Solar System
– a debate between the latest various science papers and their
authors. (More on that later…)
But Stone now says the evidence
in clear.
“This conclusion is possible from the space craft’s plasma wave
instrument,” Stone said. “The 36-year old probe is
now sailing through uncharted waters of a new cosmic sea and it has brought us along for the journey.”
Voyager's 36-year, 13
billion mile journey began in 1977.
The untold want by life and land ne'er
granted,
Now, voyager, sail thou forth, to seek and
find.

Reminds me of Wim Wenders' contribution to the Martin Scorsese documentary 'The Blues' entitled 'The Soul of a Man', in which the Blind Willie Johnson recording of that title is added to the disc with other Earth information and sent into space. It's been awhile since I've seen that but I'm thinking that it's Voyager.
ReplyDeleteHi Gary -- Sorry for the delayed reply. Your Wenders comment sent me off on a blues expedition for which I thank you and thank you. Hope things are good where you are. It's a beautiful day in Chester County, PA. Curtis
