Voyager 2 Speaking In Tongues 260
dangle sends in an update from the borderland of Sol. "Voyager 2's flight data system, which formats information before beaming it back to Earth, has experienced a hiccup that has altered the pattern in which it sends updates home, preventing mission managers from decoding the science data beamed to Earth from Voyager 2. The spacecraft, which is currently 8.6 billion miles (13.8 billion km) from Earth, is apparently still in overall good health, according to the latest engineering data received on May 1. 'Voyager 2's initial mission was a four-year journey to Saturn, but it is still returning data 33 years later,' said Voyager project scientist Ed Stone of the California Institute of Technology in Pasadena. 'It has already given us remarkable views of Uranus and Neptune, planets we had never seen close-up before. We will know soon what it will take for it to continue its epic journey of discovery.' The space probe and its twin Voyager 1 are flying through the bubble-like heliosphere, created by the sun, which surrounds our solar system."

It would probably cost a good bit more than that to build a long-range probe that has to work for many years before reaching its target. Also, you have to pay for ground stations and personnel to monitor it for the years it takes to get somewhere. We have no magic "get-there-fast manner" today; in fact, the Voyagers were able to do so much because of a once-in-our-lifetime planetary alignment (the Grand Tour). The NASA New Horizons probe is going to Pluto (and beyond), and it will take 9.5 years to get there (and if the launch had been delayed by another few weeks, it would have taken several years longer because there wouldn't have been a Jupiter slingshot fly-by).

For those kinds of speeds it wouldn't matter. Relativistic time dialation doesn't really get going until you are a good % of the speed of light.

Of course, with the aliens towing in the spaceship, that might be off a bit :-)

Well, no. The outer planet approximate syzygy provided the most efficient profile, mission timewise. You can always gravity sling from one sufficiently massive planetary body to another, using the correct entry and exit vector for the current velocity, it would just take longer to visit them all at this point in time, as you might have to go all the way across solar system to reach the "next" body and then back across again for the next hop.

The short answer is no, Voyager's frame isn't different enough to the Earth's for that huge a time dilation to have occurred purely because of that.
The long answer requires recourse to general relativity, which I'm far too tired for I'm afraid.

Out of 500 odd total hours in a month for 70m (there are 3 stations, after all)...
There aren't a whole lot of missions using the 70m right now (Cassini, New Horizons). Lots more on the 34m antennas, but there's also more of them.

I'm pretty sure the Voyager probes are the exception to that, since they're aimed to actually exit the solar system rather than eventually returning.

Pissaw, young'uns don't know anything anymore; more likely a fried 1452 core sense amplifier. That bad-boy left Earth back when a 1024 Bit, 500 mS static ram was exotic, and yes that is bits not bytes and milliseconds not nanoseconds. Ferrite Core memory was the state of the art back in 1977, when hard-disk drives were the size of washing machines and I was a young'un myself punching Fortran code on to cards.

The CPU likely started running at 1.79 Mhz, but they've probably dialed that down to save power decades ago; unlikely any form of error-detection was used.

Did you notice that the RCA 1802 page you linked to specifically says that the chip was not used on Voyager?
