I'd guess they're going to send up another pair in 2014. That way by the time STEREO A and B are back on our side and lose their view of the back of the far side of the sun in eight years, STEREO C and D will be just entering range.>> ^DonanFear:

Too expensive.
They would need to carry a lot of fuel to slow down when they reach their destinations and they would need to use way bigger rockets to get all that extra weight to leave Earth orbit.
At least while they're behind the sun they can check if there's another Earth back there!

I don't understand why the satellites pass each other (I mean, I understand, physically but..), why didn't they set them up to orbit at the same rate in the same direction so that there is always a view of both sides of the sun (since they'd always be separated by 180 degrees)?

You're like my personal dupeof nemesis. Oh wait, you're Super Duper Level 61, I guess I won't take it personally then.

So I get to turn the camera around and see the director and crew staring wide-eyed at the stars? Not sure if I'd really want that. >> ^Khazuul:
Inevitably, this technology will be used in porn.
It will be awesome.
