How far can Voyager 1 go before we lose contact?

In 1977, the Voyager 1 space probe was launched
to study the outer solar system. The two Voyager space probes have become the longest operating spacecrafts in spaceflight history. 41 years later, Voyager 1 is now 19 Billion
kilometres from Earth and travelling at 61,000km/h. Despite Voyager 1 being the furthest man made object from Earth, we are still able to communicate with the space probe on a regular basis. But how far can it go before we can no longer communicate with it? To answer this, we need to know how Voyager 1 receives and transmits data from 21 Billion Kilometres away. A 20 KiloWatt signal is transmitted from Earth
to Voyager 1 using radio waves. It takes almost 20 hours for the signal to
reach the space probe where it’s sensitive antenna picks up the signal. For comparison, it takes the rovers on Mars an average of just 15 minutes to send messages back to Earth. Voyager starts sending data back to Earth using a 20 Watt signal. As it travels through space, the signal strength weakens. And by the time it reaches Earth, the signal is barely detectable. In order to communicate with objects that
are this far away, it doesn’t really matter how strong the signal is, as long as you have a receiver that is sensitive enough to pick it up. NASA uses the Deep Space Network which consists of three Antenna complexes equally spaced around the Earth. Each complex has a huge 70 metre antenna along
with multiple 34 metre antennae which can be combined to pick up signals that are thousands of times weaker than your standard FM radio signal. The Deep Space network spends several hours
each day listening for faint signals from Voyager 1, and so far, it continues to talk
back to us. Since our methods for detecting signals has
improved drastically over the past 50 years, there isn’t really a limit on how far we
can communicate with objects in Space. With our current technology, we could reliably communicate with objects that are many light years away from us, as long as our receivers
are sensitive and accurate enough to pick up the extremely weak signals. As Voyager travels further and further away from Earth it takes longer to send and receive signals. The signal strength also gets weaker and data
rates become slower making it harder and harder to communicate with the spacecraft. Voyager 1 will continue on it’s journey
indefinitely, and although there is technically no limit to how far we can communicate, our communication with Voyager 1 only has a few years left. Since Voyager 1 is Nuclear powered, it’s
electrical power weakens each day. In 1990, in order to save power, engineers
turned off the spacecraft’s camera after Voyager took the famous “Pale Blue Dot”
image, which showed Earth as a tiny blue pixel against the darkness of space. Today, only 4 out of the 11 scientific instruments
on Voyager 1 are still active. These instruments are being used to collect data on magnetic fields, solar winds and cosmic rays outside of our solar system. In around 8 years, Voyager 1 will completely
run out of power and will no longer be able to keep it’s instruments going. Scientists will continue to communicate with
the space probe and receive the important information it gathers until it eventually
sends its last bit of data and disappears silently into space, never to be heard from
ever again. So although the end is near for the Voyager
space probes, we can appreciate the incredible journey they have been on and the valuable
science they have taught us. Thank you to the Primal Space Patrons who

  1. So it said its billions of miles away yet the farthest they have seen through a hubble is 13.4 billion miles….. I'm lost

  2. Poor Voyager it has traveled so far, more than any human .Poor rover on Mars has already sent his is seeing black. Which valuable science did voyager give us?Did it pass the Oort cloud b/c that is going to be of interest to us humans in the next few years. Actually humans are very helpless to stop what is coming.Science was a waste of money and energy.I think of those people who are listening all day and night for some faint signal?
    If those brains were only utilized more productively…

  3. So degredation of the signal and the ever larger size of the antenna are factors… And people still think listening for alien radio signal is a mean to detect life on other planets ?

  4. Calling voyager "it" sounds odd. Better call it she or he or juat voyager. With that much of a relationship I think it should be Hon. Voyager or Mr & Mrs voyager since there are two.

  5. "My reactor is dying, im getting sleepy"

    (Voyager 1 spacecraft)

    1 like = one prayer for voyagers 1 and 2😥

  6. One day when we have a spacecraft similar to the Enterprise, we will go out and retrieve the Voyagers and put them in the Smithsonian.

  7. Why can't it take a real photo of earth ,I'm not buying that story , and hasent broke down after all that time ,what's the close up photo of earth like .

  8. If voyager loses power than it will still keep going at the same velocity because in space there is no gravity barley any atoms, only like one or 2 in between stars, and as y’all already know there the building blocks of the universe. But atoms are not in the “space” ,why well space go figure. voyager left earth at approximately 60,000 kilometers per hour and continues to fly at that speed, picture it as a human kicking of the ground, but of course that wouldn’t wouldn’t launch a human in to space because of earths gravity. now in space there is no matter nothing to keep the voyager from its infinite voyage across space at the same velocity. So if the voyager where to lose power Tomorrow, the only things it wouldn’t lose would be its “parts” and his speed, unless direct out of his general direction by a tremendous force of power, and as we all know there’s plenty of that going around in the universe, so there ya go.

  9. Logically am unable to accept this Voyager travel path,How can a tiny probe wander around the space without being hurt by space dust , asteroids , Powerful Magnetic fields of huge planets , Space junk , high speed meteoroids ? Wonder how NASA is fooling world and to my amusement no one has raised this point till now are we getting that dumb ? Do probe has any mechanism to protect from those powerful stuff?

  10. Don’t worry Voyager, i’m sure if people develop faster than light travel people will one day come and find you and put you in a museum.

  11. One day, like 1 trillion years from now, Voyager will crash land on a planet and the inhabinhabitants there will be like wtf.

  12. They should design a probe that as it flies into the void it drops smaller relay satellites so as its communicating the signal doesnt slow down

  13. Summary There is no limit of distance to lose contact from Voyager 1, unless it runs out of energy in ~ 8 years, where it would have traveled another ~30 AU (with a total of ~175 AU from its launch – i.e. roughly 0.0027 Light years in 40 years). But most importantly, this would be even more emotional than Stark dying in the Endgame.

  14. Keep teaching this to us humans we love the joke..teach this crop to animal and they laugh at you.

    I'm not sending any of my children to school to be dumb down, the wiser the person who didnt go to school.

    Science is fairytales, history is painted, religion is control, mathematics..well it's easy life came into existence with a big bang, yes mathematics means taking something from nothing, geography is comedy..
    And the list goes on.

    NASA I personally want to give you an award for deceiving the whole world. Those who go to university should claim reparation.

  15. 4 years eh? Originally it was supposed to last at most ten years, it's been more then 40 years now , not so sure they know what to expect when it comes to its life span

  16. you said something wrong, when the probes will no longer transmit, your second mission will begin: to witness our presence in the universe, with the golden recorde

  17. I want to give voyager a hug. 😭😭 i feel sorry for ditching it. Can anyone throw me at 64000kmh? I'm open for suggestions

  18. What if in years times they disciver a new probe thingy with way vetter signals and it sees voyager 1 just chilling in space

  19. You have been deceived by the greatest ever deception on humanity.. Time to wake the [email protected]# up..

  20. Voyager 1 and 2 will be tracked down and returned to Earth in a couple hundred years when we have "Star-ships" that can travel that distance in 2 days! Returned to the Smithsonian?

  21. what about Pioneer 10 & 11 thought the two probes sent out before Voyager,s are further away, heading out the heliosphere, they are still working but no longer receiving commands i believe but i could be wrong

  22. Why did take such a very small picture of the esrth. Why didnt take a live picture…close up about the distance of thr moon so we could truly see what it looks like

  23. This is strange why does frequency get dimer in space when there is nothing to stop it like an object or really anything that has some sense of mass? Space is just that so it should be possible to beam a signal from even thousands of lightyears away.

  24. 1977… The voyageur 1….contains the wealth of earth ..
    2…contains samples of human communication..
    3…contains the human DNA strands …
    4 contains earth's finest electronics and communications…
    5 contains the information on humans ..
    6 contains the direction on how to get to earth…

    To me….that's a enemy of humans information gathering return beacon …

    Those in power rule this world in lies and illusions and have done almost every study of man under every condition imaginable….

    Including rule them in lies and illusions…

    There is another world near earth that is nearly invisible to the naked eye due to a polarized atmosphere…
    Useing a polarized lens allows you to see Thier invisible rainbow atmosphere that absorbs the sun's rays instead of mirroring light…
    It looks like a black hole but it's not…
    In space the earth reflects and bounces light when the sun lights it..
    In space…a black hole absorbs light to hide a planet….

    The trick is….the timeing of the moon phase of 15 days and a one day every few years. The sun eclipse the black hole from earth .

    The sun exposes the black hole or invisible planet or dark polarized atmosphere…

    The moon can't be in two places at once…

    Especially if the moon does a fly by a not a rotation around earth.

    So they wanted to know where the moon disappears to..

  25. Alien Astronomer #1: What is that?
    Alien Astronomer #2: AAH ALIENS!! THEY'RE COMING!!

    Voyager flys by

    The aliens: phew…

  26. This problem can be overcomed by making Voyager 3 which will be placed at half o the distance between earth and Voyager 1 and helps to transfer data to 3 and then to earth

  27. I like how it’s so sad to say that in 8 years we’ll hear the last words (signal) from the voyager and that it will keep drifting in the voids until infinite

  28. Damm it really hits you when you know it’s gone into space never to be seen again by us, but what if other species retrieve the voyager 1 and find out they are not alone. Oh my daze, I’m starting to get emotional who else?

  29. (KJV)(Hebrews 9:27) And as it is appointed unto men once to die, but after this the judgment
    (KJV)(Revelation 21:8) But the fearful, and unbelieving, and the abominable, and murderers, and whoremongers, and sorcerers,
    and idolaters, and all liars, shall have their part in the lake which burneth with fire and brimstone: which is the second death.
    (KJV)(Mark 9:44) Where their worm dieth not, and the fire is not quenched.

    (KJV)(Proverbs 27:1) Boast not thyself of to morrow; for thou knowest not what a day may bring forth.
    (KJV)(James 4:14) Whereas ye know not what shall be on the morrow. For what is your life?
    It is even a vapour, that appeareth for a little time, and then vanisheth away.

  30. With the advanced technology we have nowadays, I'm sure we can make something faster and better than Voyager 1 & 2 out of homage

  31. This was rover from Mars last word

    "My battery is low, and it's getting darker"

    -Opportunity 2004-2018

    I am crying for an spacecraft damn! it's not nice to be lonely for 4 decades.

    I wonder what last word Voyager 1 will use, what do you expect folks?


  32. They should of programmed them to link up between satellites so if ones sends a message the one nearest to it captures the signal and then resends it, same way with sending signals to them

  33. Hope they will thinks how to charge a batery using radio wave.. by sending thousand gigawatt of elektricity microwave to charge the batery

  34. We could simply build bigger and bigger satellite dishes to keep communication going. After that fails, we can launch communication relays using the slingshot effect and new better thrusters to catch up to the voyagers.
