voyager 1 please take me with u !!!!

[petlovergirl234]

WHAAAZZZZZAAAA? Please.... I don't geyt it.

[MidnightRedemption]

i feel so small...

[MaroonedInSpace]

I've heard that the Voyager1spacecraft has recently detected a change in direction of the molcules around it!

[knowpassword]

kudos to the math men and women..

[FloridaRaider]

How does Voyager still have power to transmit back to Earth after all these years? Wouldn't the temperature of deep space freeze up the working components?

[KurdstanPlanetarium]

@FloridaRaider good question! well Voyager was equiped with a Nuclear Battery to last of at least 20 years and that provided with the power to comunicate and preserve the sensitive elctornics, whether its still in working condition, yet we have to know, but then we dont expect to send us back anything once in the interstellar medium. it just becoming a visitor to alien worlds, if any came across !!

[knowpassword]

@KurdstanPlanetarium plutonium power yes?

[redspider2005]

@FloridaRaider Voyager 1 and 2 needed the Radioisotope Thermoelectric Generators (RTGs) (Plutonium generators) to run their powers. They didn't need the solar panels because our sun is too far. Voyager 1 and 2 needed the all-black thermal blankets or coatings to keep them comfortable in the extreme cold temperature of the deep space. They took about an hour to transmit data to us from Jupiter and 1.5 hour from Saturn. Voyager 2 took 2.75 hours to transmit from Uranus and 4 hours from Neptune.

[tomjankinson]

@FloridaRaider this fuel called "pluton 238", to 2020 year it should work

[x0lamborghini0x]

@FloridaRaider Radioisotope thermoelectric generators, which transfer the heat created from the radioactive decay of plutonium-238 via thermo-couples to produce electricity. The half life of plutonium can extend beyond two decades, but the deterioration of electrical power available will occur every year. Something like that anyway! :p

[rgrggfdgfgr]

Is this video about the Trajectories of the Golden Record Voyager or somthing else?

[KurdstanPlanetarium]

@rgrggfdgfgr you might think of it as the Golden Record on Voyager as part of it, but for sure this was the Golden Trajectories (The Grand Tour), that put knowldege of the outer planets in our hands and paved ways to the Stars

[rgrggfdgfgr]

@KurdstanPlanetarium Oh, Thanks for answering my question and I like this video. Also I checked out your page and liked that as well keep up the great videos, and thanks again!

@STORMCAT06 Thanx for the reply...let me put it this way to you...the Apollo Project cost at its time $24 billions and took 8 years to complete, 120000 people were recruited in various branches of Science..and cost at least 3 Astronauts lives (Apollo1)...even an Astronaut space suit cost £1 millon, shouldn't we think that the desigers were taking extreme efforts to overcome radiation problems en route and on the Moon itself? I myself think yes they did

[KurdstanPlanetarium]

@STORMCAT06 Interesing topic, to be honest I m not expert in Space flights as I m an Astronomer, and if you know that the 2 Van Allen Belts extend to hights of 19000 Km, so Voyager with its speed of more than 43000 Km/hr could have crossed it in half an hour, but with all deep space missions Spacecraft desingers have to overcome these problems to protect their valued sensive equipments, or else what is the reason to send them if they cant protect them. same goes for manned Lunar missions

[KurdstanPlanetarium]

@STORMCAT06 well you know most radiations can be shield by a thin layer of lead plate or Aluminum which is what Voyager Spacecraft was made of...

[Armigo91]

True, gravity is everywhere. The craft would need enough velocity to become halway to centauri in order to escape from the suns gravitational pull. It would need a velocity of several hundreds kilometres per second to escape from the sun forever. Eventually it will fall back and remain in a very large orbit around the sun. A orbit similar to senda probably, maybe even larger. It will take several millenias and then voyager will come back to our neighbourhood.

[ShinichiIzavara]

@Armigo91 The escape velocity is hundreds of kilometers per second near the sun, but where the probes are now, it is only a few kilometers per second. Four man made objects, pioneer-10, pioneer-11, voyager 1 and 2 have the escape velocity. they will never return. The ultimate X-prize would be to capture and bring back any of them :)

[WaiWu]

@ShinichiIzavara great idea, future generations will try to capture the probes and sell 'em as antique =D

[voxdeihn]

muy bueno, gracias, por donde iran hasta el dia de hoy?

[KurdstanPlanetarium]

@voxdeihn thanks you...

[Cookenour]

Keep in mind that the Voyager crafts will eventually arc back towards us. The once project leader even said that they have lost over 5,000 mph already and that Haley's Comet is a perfect example of how the crafts will simply never travel straight way and away from us. Like the comet, the Voyager crafts will very, very slowly work themselves into an orbit taking them far away and near. Just like Haley's comet and other space bodies not freed from visiting us on a huge orbit.

[KurdstanPlanetarium]

@Cookenour that maybe true but I think a body that takes a Parabolic orbit its an open arc that never return to its point of departure...dont you think Voyagers is taking such arcs...

[glassminimalist]

@Cookenour They are slowing, but after the Jupiter encounter the Voyagers attained a velocity greater than the escape velocity from the Solar System.

[ctchrinthry]

@Cookenour No. There is something called "escape velocity" and the voyagers both have it; the sun won't recapture them ( unless they get slung back by a black hole or aliens... Very very very unlikely ).

[eakaltun]

Hawking said couple weeks ago interesting thing that contacting with aliens could be not a good idea indeed and they could harm the earth and humans. After read this and when I read the news that the voyager started to send messages in unknown code, I am thinking now : what Hawking said can be related to those messages which still cannot be encoded?

[KurdstanPlanetarium]

@eakaltun yes there is still a danger if Aliens find out about Earth, I mean a dying race Alien that looking to find a home for their dying species...but who knows we may one day face an Alien that teach us how to cure disease and use our resources more wisely..who knows?

[eakaltun]

@KurdstanPlanetarium , yes but what hawking said is disturbing, they may be looking for sources to consume.

[eakaltun]

kurmanci zane? This is realy good user name :-)

[olmecbones]

And it worked like a charm...

[seaquat]

i was young then ;) :)

[nalcow]

I was a baby then.

[Cookenour]

This just reminds me of the scripture in the Bible that says that space is but the span of His hand. The cosmos is so fascinating. Thanks for posting this clip.

[KurdstanPlanetarium]

you welcome...

[MicrosoftsourceCode]

I would love to see a slower and clearer trajectory video clip. that was too fast and nothing explained. I guess I will have to figure it all out myself as usual. I really want to figure out how one would plot a trajectory to another star, one that is near. People on yt talk about interstellar travel but before you take a journey you should plan it.

[KurdstanPlanetarium]

well my friend Voyager took decaced to reach its last destiny, so if you want a slower one certainly must take if not decades but hours to see...the video definetly shows the 2 voygers route to Jupite first then Saturn, aftward to Uranus and last to Neptune it was part of so called the Greand Tour, an opportuninty came when all the outer planets apart from Pluto lined up and NASA took the opportunity to send 2 great spacecraft to do the job...they now on thier way to the intersellar space...

[KurdstanPlanetarium]

Just to add:

Voyager 1 ended after reaching Saturn, then the rest was only explored by Voyager 2, as clearly visible from the video...

[ffgerty]

@KurdstanPlanetarium No Voyager is still travelling at like 94 million miles a year. Voyager 2 took a slower, longer route in the opposite direction.

[MicrosoftsourceCode]

I am trying to figure out what it takes to travel from our planet to the nearest star. @ some late stage in the journey a ship would break away from our solar systems gravitational pull and start to get pulled in by whatever new planetary system. It would be interesting to see the relationship between our systems gravitational force with any near star system.

[hesitation24]

I don't know much about space but will the voyagers continue to forever drift deeper into space after they power down (assuming they don't bump into hot asteroids or stars) or will UV radiation completely destroy them?

[KurdstanPlanetarium]

sure will continue as an object drifting in space unless as you said bump into something....

[hesitation24]

that's cool. I wish I could be one of the voyagers.

[VampireYoshi]

Actually, it was much easier to get the Pioneers and Voyagers to their outer planet destinations than it was for, say, Galileo and Cassini because they weren't staying. A fly-by requires exactly that: to pass by the world. Orbital insertion requires a degree of control that was impossible for the Voyagers because of their much higher velocity.

[skyarsalan]

kinda sucks that it wont get there in our life time.... :( hmmm well it might not , but what about somethign else?

[Beezy2127]

wtf????

[katanoob]

lol, what is hard to understand?

[KurdstanPlanetarium]

the only thing that preventing a spacecraft a comet or meteor when passying close by a planet is its velocity. every object whether planet or moon have their own escape velocities, for Earth that is 12 km per second, so a craft that reach that velocity will escacpe earth to Space. that same rule applied when sling shoting a spacecraft to use Gravity assist of that planet it must have velocity higher than that planet's escape velocity, then it passes by and escapes easily without being caught.

[KurdstanPlanetarium]

hey dvs1572, thanx for the comment, you wonder about gravitational pull of a planet (sling shot) to help a spacecraft to speed up to another destinations, well the idea is fine but remember what we get in velocity, we loose it in time, as a spacecraft has to be shot several times to same planet in order to get enough velocity to its destintion, look for example Cassini space craft it passed by Earth - venus twice in ordrer to reach Saturn but that took 2 years of its time.

Whopper Video!

Great work bro.

Thank you
