Voyager - The Interstellar Mission (http://voyager.jpl.nasa.gov/)

Built up to a standard, not down to a budget.

When you consider the possibilities, are the two Voyager craft anywhere near each other?

I think we should be told.

the data the spacecraft has been sending back from more than
11 billion miles (18 billion kilometers) away from our sun.

IIRC both V1 and V2 warranties were only for a billion miles. These
craft were built to last!

It is 270,000 AU to the nearest star Proxima Centauri.

At 61,375 clicks/hr (relative to I don't know) its gonna
take a while to get there, but which way are these craft
pointing anyway? (my conection to JPL is very slow so
its hard to look it up).

Well, from my point of view they both still seem to be going up... :}

Or, if a BBC listener. How many olympic swimming pools?

For those who cannot visualize billions...

Think of it as crossing Canada 2,076,125 times! :} :ok: :8

When the Voyager team put the new data together with information from the other instruments onboard, they calculated the moment of escape to have occurred on or about 25 August, 2012.

At about teatime... :} :} :}

I read somewhere that Viking was not following accepted Newtonian physics (in terms of it's position).

Which means that another force is out there that either we don't know
about or can't see - ie another planet or black hole ?

You would think so 500N, however IIRC there was no explanation for it at the time (that may have changed).

I think RGB came up with it this morning.

It's your heaven, a dirty big crepe out there somewhere :O

I wonder how many of the factories that made parts for them are still there? Certainly the one in Swindon that made some of the integrated circuits for them is now derelict......No spares available!

I thought they were parked on Mars.:confused:

It certainly wasn't if it ended up in interstellar space!

Ah, we've located the engineer's missing sandwich of which the added weight has caused the discrepancy.

At least we now know how life started in other parts of the universe :}

Intercepted communication: Proxima Centauri control to approaching spacecraft: "Please turn-on your IS-IFF and/or identify yourself (supply Inter-stellar IFF number), or risk being destroyed on current trajectory. On present course and speed, you have approx. 4 light years remaining during which to respond before we will be obliged to take defensive measures. :ugh:

IIRC the Voyagers were sent off at different angles out of the plane of the planets. One going up and the other down.

The other possibility is that was done with the Pioneer probes. My memory fades quicky these days :}

Dak Man

I was mistaken, it's the 2 Pioneer probes that are disobeying the laws of physics as we currently understand them.

And I always thought they was no up nor down in space... :confused:

According to Wiki they are following the laws just fine, thank you.

"By 2012 several papers by different groups, all reanalyzing the thermal radiation pressure forces inherent in the spacecraft, showed that a careful accounting of this could explain the entire anomaly, and thus the cause was mundane and did not point to any new phenomena or need for a different physical paradigm.[2][3] The most detailed analysis to date, by some of the original investigators, explicitly looks at two methods of estimating thermal forces, then states "We find no statistically significant difference between the two estimates and conclude that once the thermal recoil force is properly accounted for, no anomalous acceleration remains."[4]"

I would like to think that in the future, we will be able to send out a team to retrieve both Voyagers in a matter of a few hours.

(Just as soon as we learn to stop killing each other over stupid stuff.)

Indubitably. My ex-wife was quite certain she was the center of the bloody universe... :}

Only as long as the bloody Klingons don't get to it first.

Amazing stuff.

Here's a reminder of the 'Golden Record' that was affixed to the Voyager, including the list of songs along with instructions on how to play the record. Good to see Chuck Berry's 'Johnny B. Goode' made the list!

Each record is encased in a protective aluminum jacket, together with a cartridge and a needle. Instructions, in symbolic language, explain the origin of the spacecraft and indicate how the record is to be played. The 115 images are encoded in analog form. The remainder of the record is in audio, designed to be played at 16-2/3 revolutions per minute. It contains the spoken greetings, beginning with Akkadian, which was spoken in Sumer about six thousand years ago, and ending with Wu, a modern Chinese dialect. Following the section on the sounds of Earth, there is an eclectic 90-minute selection of music, including both Eastern and Western classics and a variety of ethnic music.

See, I want the Klingons to get here and get here soon.... I think a night with a Kilngon female would be a wonderful and honourable way to leave this life... :}
