The effect is something like when you're driving a car and the photons from your headlights are pushing you backward

I hate daytime running lights. Sometimes I need that last bit of forward thrust.

They dismissed it as the effect of dribbles

Cool. I think it would be cooler if we had to revise the theory of gravity, but it's still amazing that you can actually measure heat slowing down a spacecraft.

I think we know the source of all this heat -

(* sigh *) V'ger was a Voyager spacecraft, subby. Not a Pioneer spacecraft. Get your sci-fi geek facts straight.

Yeah, if Pioneer came back, it would be P'ner.

A lot of people can't wait for P'ner to come.

Unless I'm not understanding something.... isn't this heat that is being radiated out? Shouldn't it be radiating out equally in all directions? And if, for some reason, it's only radiating out the front*, does this mean they'll just stop in the middle of space eventually? Or will they run out of juice before they stop?

* - Too bad they didn't engineer it to radiate out the back instead!

I installed unsealed off road brights in my tail lights for that extra bit of speed.

Heat makes the P'ner speed up though.

It's a dry heat so not so much

So that's why it kept calling him "Kirk Unit".

Grither: Unless I'm not understanding something.... isn't this heat that is being radiated out? Shouldn't it be radiating out equally in all directions?


Yes, except there is this big farking dish antenna that prevents the heat from being radiated to the "back".

And if, for some reason, it's only radiating out the front*, does this mean they'll just stop in the middle of space eventually? Or will they run out of juice before they stop?

It's a simple math problem. You can find out it's current velocity on teh intarwebs, and TFA mentions the rate of deceleration. High school physics question to figure out when it will hit zero velocity, assuming the heat stays constant (which it won't).

* - Too bad they didn't engineer it to radiate out the back instead!


It wouldn't matter. The magnitude of the effect is so small that you gain no real benefit.

I think the issue is that big dish on the back while the electronics are on the front.

As the nuclear battery decays the heat will drop.

That explains the dribbling.

Does P'ner go into V'ger?

Not to mention that the 'belt buckle' thingies were made of brittle plastic, and kept breaking when
people brushed up against railings, of which there were quite a lot on the ST:TMP set.

Kirk uses his hands to scrape centuries of corrosion off the Pioneer plaque: "P'ner!"
Spock: "Captain, there is no name printed there."
Kirk: "No, it's a drawing of a... of a.... Bones?"
McCoy: "It's a peener, Jim."

YER DOON IT RONG

// finished reading Cosmos last month
// amazing how much has changed in the 30 years since that came out
// how much more out-of-date will it be in 2050?
// it'll still be awesome, though

I get this reference! See, in one of the Star Trek episodes they found an old Voyager probe but part of its letters were missing. All that remained: V'ger

That data robot dude made a poem for it, something . . .

Citations weren't made until 1980 (had one).
