Voyager spacecraft finds solar system is bigger than thought
CNN ^ | Tuesday, December 4, 2012 | CNN Wire Staff

Posted on 12/05/2012 9:41:12 PM PST by MinorityRepublican

An artist's concept of NASA's Voyager spacecraft, which is now about 11 billion miles from the sun, NASA said.

(CNN) -- Are we there yet? If you're Voyager 1 and you're looking for a spot beyond the end of our solar system, the answer is no.

NASA officials have been saying for months that Voyager 1 is almost there when it comes to interstellar space as it continues the longest road trip in the history of mankind.

Voyager 1 and Voyager 2 took off 16 days apart in 1977, and Voyager 1 is now about 11 billion miles (18 billion kilometers) from the sun.

On Monday, project officials said new information sent back from the ship yielded a surprising result.

"If we would have only looked at particle data alone, we would have said we're out of the solar system," said Tom Krimigis, a scientist from Johns Hopkins University who examines data on low-energy charged particles. "But nature is very imaginative, and Lucy pulled up the football again."

The Voyager team believes this region is where lines of magnetic particles from the solar system are meeting particles from interstellar space.

I've always said the heliosphere was larger than expected by current theory.

Well, I've said it now, haven't I?

Amazing that the solar powered spacecrafts are still operating. Wonder if they still send signals and probably takes several minutes for the signal to reach earth if so. I think the light from Sun takes 9 minutes to reach earth.

It will take a LONG time to travel 16 TRILLION miles, indeed! Of course, that does not include 84 trillion in unfunded liabilities.....

There are some scientists who started on Voyager shortly after college, and have spent their whole career on the project.

The Voyagers are nuclear powered craft. Where they are now, the sun is so far away that it only appears as a slightly brighter star than the rest.

It’s powered by Plutonium, And the signal flight time is about 17 hours.

Actually $16 Trillion is our GDP every year.
It is the unfunded liabilities estimated in the range of $80-100 Trillion which is the real big deal.

Perhaps at the end voyager will come across a big painted wall with the stars as little lights on it? :)

“The Voyager team believes this region is where lines of magnetic particles from the solar system are meeting particles from interstellar space.”

So in other words, they’ve entered the heliopause, but it’s bigger than they expected? Once they get to the midpoint, the field lines will reverse.

Err, pretty sure they’re nuclear, and the signal takes about 19 hours.

Allow me to brag a bit. Dear Old Dad (may he RIP) managed the program to build the radioisotope thermal generators (RTG) for the Mariner Jupiter Saturn spacecraft, later named "Voyager." It is always thrilling to hear about some new discovery by the spacecraft powered by Dad's RTGs. He was really proud of that accomplishment and I was extremely proud of him.

Thank you for this post. Now just imagine if we had politicians who would be blessed with similar great minds, just think where we could be. Instead we have some of the dumbest imbeciles money could buy.

WOW that makes sense...still amazing longevity of nuke power...I guess it requires minimum thrust to propel through not much gravity.

This is the kind of figurative thinking I’d prefer people with the word “sciences” in their job title, not to have.

Where they are now, the sun is so far away that it only appears as a slightly brighter star than the rest.

Hopefully I figured this out right:

Distance from the sun in earth orbit radii = 11 billion/93 million = 118.3

So the sun would appear 1/118^2 = about 1/14000 as bright at this distance.

This would imply an increase in apparent magnitude by log(14000)/(log(2.512) = 10.36.

This would give the sun an apparent magnitude at this distance of -26.74 + 10.36 = -16.38

which is still 25 times as bright as the full moon.

So the sun would look like a very bright star indeed.

Voyager received the bulk of it’s velocity from the rockets that
launched it and the rest from using gravity of the gas giants to
impart velocity via directional change.....i.e slingshot method.

The thermal generators are to power the electronics....not for
propulsion.

I’m pretty sure that these spacecraft are powered by plutonium.

Brag all you can... Your Dad did a great service to help expand our knowledge. I get discouraged sometimes by the some of the folks that we share this planet with who are fascinated with the Kardashians, etc.
They don’t realize that we are in a race against time(at best, we’ve got until the sun starts expanding as it nears the end of its life). We need to figure out hOw to live and work and survive out in space.
Anything that helps us gain knowledge towards that goal is a benefit for all mankind. Your Dad is a hero in my book.

Wonderful family story! I miss being excited by what NASA had recently accomplished. (Because of course, Muslim Outreach is not an accomplishment, it is an agenda) But I still get excited about NASA’s long ago accomplishments!

As well you should be. Too bad that the Democrats have destroyed the NASA that he was typical of. It has truly lost its way.

All deep space probes are thermonuclear battery powered.

Plutonium as a heat source and peltie effect thermocouples to generate a voltage and current accross the heat of the plutonim and cold of space.

I think it's about the size of a roll of paper towels. It is located on the end of the boom to keep it's particle emissions out of the space probes sensors.

It doesn't need thrust. It's following Newton's first law. (an object in motion will continue on it's course in a straight line unless acted upon by an outside force). It needs power to run the onboard instruments and power it's transmitter when it radio's back to Earth.
