May i know how the Voyager 1 spacecraft can still sent the signal at 16.976 billion km from earth out of the Solar System
and the power supply can stay until 33 years since lunch at September 5, 1977 33 years ago
it is very Geat ...

if you go to the wiki page it have the list of capability it is shutdown due to power limitation

http://en.wikipedia.org/wiki/Voyager_1



it is using Radioisotope Thermoelectric Generators which is a nuclear battery, you wont want to power you handphone with those bad boy. even though a battery that will last decades is tempting

My goodness, the last time i remember talking about Voyager1 or 2 was in school. I found it fascinating to think that a spacecraft was flying though space sending information back to earth (of course in the head of a young girl that 'information' was obviously pictures as if they were taken out of a low flying airplane window showing trees and such on distant planets) and would keep going for (what seemed like) forever.

Makes me quite sad to think of it slowly shutting down bit by bit. I think i get a little too emotionally attached to technology (and subsequently tend to anthropomorphize excessively).

Interesting thought though, did a quick search and didn't find a real answer from what i could tell: Is Voyager1 still communicating with earth and if so how?
I would assume radio waves, but wouldn't there be a huge (like years and years long) lag with it being so far away?

currently it is only 0.002 light years away from the sun....so go figure

there is 15 hours delay in transmition but it is still receiving command and tranferring back data.

The voyager travelling had suggested we human kind cannot escape from this solar system, without a new revolution of travelling method.

Most observed planetory/stars system is light years away. So human kind has no such kind of "life-time" able to travel or even received the signal from orbitor even the they can reach so far. As it may takes hundred and thousand of light years for the signal to travel back and forth.

as per mitchio kaku said, we cannot use current propulsion system. We must perform quantum leap.. warp travel is the key... but how do we do it? practically....

Added on September 19, 2010, 8:48 pmfor me, the only news that I anticipate from Voyager 1 is that is there any life out there?

I don't think we can get this kind of news, the travel distance or reach is simply too short in term of universe to meet one.

at http://en.wikipedia.org/wiki/Heliopause
see that Voyager 1 spacecraft is on bow shock area and
will pass to heliopause and solar wind that will damage our spacecraft

If there's anything that humankind has ever achieved to make its mark on the universe, it's Voyager 1.

After we've all annihilated each other in the Final Religious/Resource War, and the radioactive dust has settled, Voyager 1 (and some artifacts left on the Moon) will be the only proof that we were here once. And did our best to strive for the stars.

There`s this scientist shown in NatGeo who think that there`s life in Titan. Whereby the microorganism live by chemical reaction to harvest energy beneath the surface

Just wondering why they didint send out more probe like voyager ? its already 33 years old.. i think they should send a new 1 with more advanced technologies and instrument to compensate the dying out of voyager.. dont you think so?

nasa and other have plan for many more probe but dont see any that are to go outside the solar system lile voyager. maybe malaysia can lauch our own probe, then we will be doing to real space exploration.

one thing that make most sense to repeat this is the current communication technology allow for much more data to be transmitted, we can high resolution sensor and camera to study the outer solar system.

for a girl, you're weird.

Yeah, I was wondering what happened to the Satellite sent to Titan... Din't find much from Wiki... Any news to share? hehe

If not mistaken, there is some evidence sent back that suggested Titan has big hydrocarbon ocean. Titan or Titan2 or another moon nearby, which is which, forget already.

But there is no evidence about micro-organism.

like what I said from the documentary that I watch, they perfrom this search for places that mimic environment on other planet looking for life and they found it.

1) extremt cold places in deep water.... -40~60C
2) extreme hot places near valcanic activities

sadly, Voyager didnt have enough tools to hop on titan and drill through the thick ice surface.

P/S regarding roswell incident, suprisingly, US president announce that they found an unknown spacecraft after the crash but retracted back the statement and claim it was a weather baloon... do you believe it?

and what would happen IF tomorrow obama announce that aliens live among us

This post has been edited by Awakened_Angel: Sep 21 2010, 11:41 AM

there is much more information on nasa and esa own website, nasa do share their finding with the world,

http://saturn.jpl.nasa.gov/mission/introduction/


http://www.esa.int/esaMI/Cassini-Huygens/

Was it one of the series by Steven Hawkins on Discovery Channel (i think it was Discovery). I think there were only 3 in the series, 1 was 'Aliens', 1 was 'Time Travel' and the last was 'Everything' (Theories about the big bang, what will happen at the end, the possibilities for us to do deep space exploration/populate new planets).
All of them were really interesting and explain the main theories and ideas on each topic in a easy to understand (but not mind numbingly stupid) way.

The one about Aliens discussed the possibility of life on Titan in quite a lot of detail. It explained that aliens could be living in a totally sealed off sea under the frozen surface of Titan (they estimate that the surface ice is 11miles thick). It was previously though that the entire moon was ice, however then a new theory came about that because Titan's orbit is egg shaped, the gravitational pull from Saturn causing it to stretch and shrink constantly. They theorized that this stretching and shrinking would create enough heat to melt a decent sized ocean under the surface where life could have formed and may be very similar to our deep sea life.

Thinking about it i don't think it was the same one. But still very very interesting none the less.

*warning: silliness to follow*
@teongpeng - That's because this is the internet and we all know there are no girls on the internet. It is statistically more likely that i am in fact a 13 year old boy, or a 47 year old boy. In truth though i am an Alien .

Why people always believe Aliens must crash landing to earth, when we found it, or only we can find it?
They cannot come here, and waving their hand to us?
They cannot send probe just like we human kind send voyager to Titan?
They must land in US, so that secret can be kept?

What is the odd chance of alien spaceship landed in US alone, and not other countries so that secret can be kept by US gov/NASA?

Aliens can a worm type living underneath of Titan ocean, Aliens also can be microscopic organism that living underground. Aliens can also have 8 eyes so that can easily see all the dimension, up down, back, and forth without turning the head.
I had difficulty believe Alien is the same type/structure of human kind, as what many speculate.

Maybe announce that we human kind actually is Aliens. Remember there is no human kind before the dinasour ages, so we could be the Aliens concur this earth.

most difficult to believe is the alien with ship advance enough to do intergalatic space travel would crash when landing on earth.

friend... infact, I do not like the word ALIEN.. it sounds like we human are the reference point of the universe. As a matter of fact, they are just like us... satient beings.... living organism.

a guy once asked an astrobiologist "what makes you think aliens need oxygen and need water to survive?"

he answered "well, I dont really know, like physics and astrophysics, IF the laws of physics is valid on earth and our solar system, I would ASSUME it is valid as where too "

I think the voyager1 is already pass what that what we need to see, may be already pass the alien spacecraft .. the problem the probe only have black and white low resolution Camera that is 1977 camera technology .. and the signal transfer speed it very low- i cannot fine howmuch kbps the transfer speed.. if we need to sent a new probe need another 33years to reach there.. unless have a rocket boster.. but need a lot fuel

Dun think it is going to tell us if there any life out there. There are life forms out there as many meteorites has shown >>
http://spaceflightnow.com/news/n1001/09marslife/

I also wonder how will any life-form be able to play the record it is carrying?

if it was a life form with the ability to visit earth it will be able to figure it out.
