Hey i don't know much about voyager missions but how come it didn't detect the 10th planet? Is it dead?.. also how do scientist know if the voyagers won't just be thrown into a black hole or be damanged? Without any type of control over it obviously it will smash or burn up upon orbital entry. Do they think aliens will see something out the window and go out to get it then play it on their record player that they read how to put together?

Good questions but Voyager was not designed to detect planets and although I don't know the precise position of the 10th planet (2003 UB313) in relation to either Voyager, odds are, Voyager came nowhere near this planet. Voyagers 1 and 2 continue to be monitored by the Jet Propulsion Laboratory (JPL) and are to investigate the region of space beyond Plutos orbit known as the heliopause. <br /><br />More info on Voyager at the link below: <br />http://voyager.jpl.nasa.gov/ <br /><br />As for aliens, again, space is so vast that a chance encounter is remote in the least. However, the Voyagers do have human artifacts recorded on gold records, the link below has more info. <br /><br />http://en.wikipedia.org/wiki/Voyager_Golden_Record <div class="Discussion_UserSignature"> <p><strong>My borrowed quote for the time being:</strong></p><p><em>There are three kinds of people in life.

Voyager is my all-time favorite mission. <img src="/images/icons/wink.gif" /> It consisted of two spacecraft: Voyager 1 and Voyager 2. They are twins of one another, but were launched at different times and followed somewhat different trajectories. Voyager 1 visited Jupiter and Saturn before being propelled out of the plane of the ecliptic so it could observe Saturn's pole. This precluded any more planet flybys. Voyager 2, however, visited all four gas giants. A delay in the mission unfortunately ruled out a trip to Pluto.<br /><br />I will attempt to answer your questions. <img src="/images/icons/wink.gif" /><br /><br /><b>Hey i don't know much about voyager missions but how come it didn't detect the 10th planet?</b><br /><br />The Voyager spacecraft carry instrumentation designed to help them study planets as they pass near them. They are not very useful for planet-hunting, and the neccesary maneuvers to scan for planets would be very expensive in terms of propellant. Since any propellant once burned is gone forever, mission planners are reluctant to use the Voyagers for something like this. Besides, there are Earth-based instruments better suited to the job.<br /><br />Still, it was hoped that one of the Voyagers might be lucky enough to stumble upon a tenth planet. The most likely way for this to happen would be if mission controllers on Earth noticed that the spacecraft's radio signal was changing, indicating that something had gravitationally deflected its trajectory. But this would be pure luck. As it happens, neither Voyager has passed close enough to a previously undiscovered object to be gravitationally deflected by it.<br /><br />There's a lot of luck involved in detecting a planet, if it's not one of the obvious ones like Jupiter. You have to be looking in just the right place at just the right time -- and you have to be that lucky twice, so that you can see that the object has moved and therefore is not a star.<br /><br /><b>Is it dead?</b><br /><br />No. <div class="Discussion_UserSignature"> <p> </p><p><font color="#666699"><em>"People assume that time is a strict progression of cause to effect, but actually from a non-linear, non-subjective viewpoint it's more like a big ball of wibbly wobbly . . . timey wimey . . . stuff."</em>  -- The Tenth Doctor, "Blink"</font></p> </div>

Thanks.. I'm suprised they didn't include human DNA somewhere inside the craft..

You might also check the log of what's on the golden records... there may be some copy (although not complete) of our shared DNA.... Anyone have the site?

"there may be some copy (although not complete) of our shared DNA"<br /><br />The records contained sounds and pictures of Earth.I really don't think that ET anytime soon will be looking at the records.DNA was still in the making,and would be fifteen years before it was put to use.

There is a depiction of the double helix on one or both of the Voyager "records".<br /><br />Obviously a very crude depiction. <div class="Discussion_UserSignature"> <em>"2012.. Year of the Dragon!! Get on the Dragon Wagon!".</em> </div>

What you call tenth planet hasvarious connotations.When Percival Lowell used the term,he had a larger than jupiter planet in his mind.That tenth planet died natural death.What is being called tenth planet now is KBO.Word same ,different connotations.

And it wasn't a Voyager; it was clearly either Pioneer 10 or 11. (I had to wonder what the Klingons were doing shooting up space junk so deep inside Federation territory. Methinks the Star Trek folks gravely underestimated the distances and speeds involved.) <div class="Discussion_UserSignature"> <p> </p><p><font color="#666699"><em>"People assume that time is a strict progression of cause to effect, but actually from a non-linear, non-subjective viewpoint it's more like a big ball of wibbly wobbly . . . timey wimey . . . stuff."</em>  -- The Tenth Doctor, "Blink"</font></p> </div>

2003UB313 is in the constellation of Cetus.<br /><br />Voyager 1 is heading out towards Ophiuchus & Voyager 2 towards Telescopium. Neither went anywhere near 2003UB313. <br /><br />Pioneer 10 is heading outwards towards Taurus & Pioneer 11 towards Scutum. Neither went anywhere near 2003UB313. <br /><br />New Horizons towards Virgo (currently). <div class="Discussion_UserSignature"> <p><font color="#000080">"I suddenly noticed an anomaly to the left of Io, just off the rim of that world.

In response to CalliArcale. Voyager 1 could have gone on to Pluto, but was directed towards Titan instead during the Saturn encounter, passing the high latitude regions of Saturn, which meant Voyager 1 was bent too far north & travelling too fast. This was done so that Voyager 1 would see a large swath of Titan from the South Pole to almost the North Pole. Had Voyger 1 passed slightly further from Saturn & not made such a close pass of Titan, a Pluto encounter would have been possible in September 1989, just one month after the Voyager 2 encounter with Neptune.<br /><br />Voyager 2 has the stuck platform. You are correct in saying that neither have imaging capabilities anymore. The software to control the camera was deleted (god knows why) & that the power margins are getting rather low. <br /><br />It was even suggested that Pioneer 11 could have been sent passed Uranus & Neptune, but this was passed up as being too ambitious at the time & that some science at Saturn would have had to have been sacrificed, so that idea was shelved. <div class="Discussion_UserSignature"> <p><font color="#000080">"I suddenly noticed an anomaly to the left of Io, just off the rim of that world.

It was my understanding that both Voyagers launched too late to get to Pluto, having missed the Grand Alignment, or whatever it was called. (It's late, I'm sleepy.) It was Uranus and Neptune that Voyager 1 missed. Voyager 2 was still able to visit them. <div class="Discussion_UserSignature"> <p> </p><p><font color="#666699"><em>"People assume that time is a strict progression of cause to effect, but actually from a non-linear, non-subjective viewpoint it's more like a big ball of wibbly wobbly . . . timey wimey . . . stuff."</em>  -- The Tenth Doctor, "Blink"</font></p> </div>

Voyager 1 was targeted very close to Titan, this was predominately the major constraint to a Pluto flyby, IIRC.<br /><br />Voyager 1 did rise out of the plane of the ecliptic in the same direction as Pluto, and of the 2 Pioneers, and the 2 Voyagers, Voyager 1 did make the closest approach to Pluto. IIRC, about 1990 or so it was ~200 million miles from Pluto.<br /><br /><br /> <div class="Discussion_UserSignature"> <p><font color="#ff0000"><strong>TPTB went to Dallas and all I got was Plucked !!</strong></font></p><p><font color="#339966"><strong>So many people, so few recipes !!</strong></font></p><p><font color="#0000ff"><strong>Let's clean up this stinkhole !!</strong></font> </p> </div>

And at the time of the possible flyby, Neptune was further from the sun than Pluto . . . .<br /><br /><br /> <div class="Discussion_UserSignature"> <p><font color="#ff0000"><strong>TPTB went to Dallas and all I got was Plucked !!</strong></font></p><p><font color="#339966"><strong>So many people, so few recipes !!</strong></font></p><p><font color="#0000ff"><strong>Let's clean up this stinkhole !!</strong></font> </p> </div>

Actually, under the original "Grand tour" plan. One of the two probes was to have flown by Pluto. Voyager could easily have done that as it would be no different than observing one of the Jovian moons but it was a matter of trajectory rather than spacecraft design. I'm not certain if Pluto was in a favorable position for a flyby at the time of the planning for the grand tour but it apparently was or would have been. By the time Voyager launched in 1977, Pluto was out of alignment. I could verify this with Starry Night but I have to reload that back into my computer. <div class="Discussion_UserSignature"> <p><strong>My borrowed quote for the time being:</strong></p><p><em>There are three kinds of people in life.

Pluto was dropped, because it was thought that the Voyager 1 encounter with the Saturn moon Titan was of higher priority, & that Pluto was found to be smaller than originally thought, so therefore 'less interesting'. Of course we now know that Pluto despite the small size is of immense interest, hence New Horizons.<br /><br />In order for an effective Titan encounter, Voyager 1 had to pass slightly closer to Saturn & pass almost 'beneath Saturn' to bend the trajectory northward, so Voyager 1 would see a great swath of Titan at high resolution. It was not thought back then that this was a waste of time due to Titan's smoggy atmosphere, although Pioneer 11 sent back a decent image of Titan showing a smoggy ball. This meant that Voyager 1 was travelling too fast & too northwards to permit a Pluto / Charon encounter.<br /><br />Neither Voyager were designed to operate much furhter out than Saturn, but because Voyager 1 was successful at Titan, it left the option open for Voyager 2 either to go on to Pluto OR go onto Uranus & Neptune.<br /><br />Had there been a Voyager 3, then both options could have been carried out after Voyager 1.<br /><br />Because of the robustness of the Voyagers, Uranus & Neptune became possible. <div class="Discussion_UserSignature"> <p><font color="#000080">"I suddenly noticed an anomaly to the left of Io, just off the rim of that world.

Pioneer 11 image of Titan. This image of Titan was taken by the Pioneer 11 spacecraft on 3rd September 1979 from a range of 3.6 million km / 2.235 million miles.<br /><br />This object was the reason for Voyager not going to Pluto. <div class="Discussion_UserSignature"> <p><font color="#000080">"I suddenly noticed an anomaly to the left of Io, just off the rim of that world.
