Can astronauts/cosmonauts on the International Space Station get satellite TV?

(yes, this question was inspired by the Heineken commercial)

Directly from the satellites, probably not as it would require a tracking antenna to keep the dish aimed at the satellites. Also the space station would often pass behind the Earth or be at the fringes of the transmission, so there would be no way to watch programming continuously for more than a short period. I would think that any entertainment would have to be piped up from the space agencies, if at all. Good question though; I do wonder if they get any TV luxury.

Also from this Q&A: "TV is the same way, we don't have actual TV, but they can load files into the e-mail just like you get streaming video files that you can click on in your regular e-mail and they send those up, and you can click on them and watch the video."

Probably not for free.. they'd still need the decoder card in the receiver. ;-)

They're paid to be astronauts, not paid to watch TV. But if they wanted to, they could quite easily steal the tapes from the satellites and watch their shows when they get back home.

Not a chance. The satellites are in geostationary orbit above the equator. The ISS moves in a sinusoidal path relative to a square map of the earth. One revolution takes 90 minutes.

So if they had a rotating receiving dish with sophisticated tracking software they might be able to watch TV for about 5-10 minutes per revolution.

All the above is true, plus I'm sure they don't have the equipment. Nothing is on the ISS that isn't directly needed for the mission.

I'm pretty sure that the only significant communications link the ISS has is with TDRS.

I'm not exactly sure what it is you meant by this, but now I have this image of astronauts drivin' the ol' Shuttle out to geostationary orbit and openin' it up with a crowbar to get at the thousands of VHS tapes in the gooey center. Because that's how they work, right?

Of course, they'd probably do better to just form a boarding party and attack the spaceship that delivers those VHS tapes every week.

Arrr.. here there be space pirates.

Yes, I think that was the joke they were going for. Thank you for explaining it, that made it funnier. Heh.

nope ... satellite TV runs over a line of sight communications channel. No transponders on the satellite would be pointing to the ISS (or tracking if it is moving) hence no comms channel!

Why wouldn't they be able to get the signal for half the revolution, or 45 minutes? Seems like the earth is either in the way or not.

Also, the space station manages to track the sun pretty well to keep its solar arrays aligned correctly. And I think they track stars to do dead reckoning.
