NASA's 1999 Mars Polar Lander had a microphone on it, but it crashed.
The French are going to try again.
Here are some relevant links

sounds from Jupiter
http://science.nasa.gov/headlines/y2004/20feb_radiostorms.htm
an interesting discussion on the subject
http://www.unmannedspaceflight.com/index.php?showtopic=1093
On the History Channel series "The Universe" they mention that Jupiter's magnetosphere produces what's called "lion roar" or "chirping" sounds in car stereo systems. Apparently this only occurs on desolate roads where radio interference is minimal, and at certain times of the year depending on Jupiter's orbit in relation to our own.
In another series about space (it might have been The Universe again but it can't remember) they say that a small part of radio hiss or white noise is actually "sound" from the Big Bang. Supposedly the "sound" is actually radio interference caused by remnant electromagnetic energy still floating around out there from when the universe was formed.
I wonder if anyone has recording of either of these (of course the latter would be easy to get a recording of). It'd be interesting to hear what the celestial bodies are saying.
P.S. If sound had a medium to travel through in space I wonder what the sun would sound like.

I saw that too, however the amount of noise from the Big Bang is only a few percent, hardly noticable. Still cool to think that same energy still reverberates after so many million and million years.

thanx thanos.
the links you mentioned above are valuable and exactly what I was looking for.
btw: are you a musician or how it comes you have wide knowledge on the subject? Is it just a matter of personal research?
Thanx again!
Glad you found something good there, sadmac. And no, I'm not a musician, just some experience with sound editing, I don't have a wide knowledge of sounds. But I like to find peculiar ones on the net. There's so much out there these days. I hope you post a link to your piece when it's done.
Thanx again!
Well soon we will have actual recorded sound from NASA
http://www.foxnews.com/story/0,2933,431945,00.html
Check it out, this should be cool...
Wow, I can't believe they sent up such a cheesey mike! Bad Nasa, go sit in the corner.

Nasa should contact us freesounders to ask what they should send up and what things they should make recordings of. Like sounds of the Rover driving on Mars, rocks being thrown around, that Martian disco down the street...
As for crappy mic...
I am sure the microphone designer had to consider some things most studio condensers don't see too often in the studio like zero gravity, intense heat, intense cold, acceleration, impact shocks and foreign atmospheres.
The last one they sent blew up with the rocket and the russian one didn't work. The Cassini recordings are just audio interpretations of graphical data. This will be the first.
As for the requests...
I would like Martians saying "NoiseCollector Sucks" in old martian of course, modern martian is so gutteral and has an ugly idiom.
My imagination? Or is one of these stars saying, 'NoiseCollector is ph-ph-PHAT' in urban Martian. Here is another interesting collection of space sounds
Team records 'music' from stars

A BBC story on this group
http://news.bbc.co.uk/2/hi/science/nature/7687286.stm
Best quote:
Professor Ian Roxburgh of Queen Mary College, London is among those trying to work out what the sounds from the stars tell us about processes occurring inside stars.
"It's not easy," he says "It's like listening to the sound of a musical instrument and then trying to reconstruct the shape of the instrument".
Which makes me think there could be a Freesound competition to identify sounds?
Field recording only, no effects, separate prizes for accuracy and best creative lunacy...
Not as much sound from another planet, but a cool sound from an R2D2-esque droid. Enjoy.

... also ive read about pulsars
http://www.jb.man.ac.uk/~pulsar/Education/Sounds/sounds.html
There was a link from another forum thread to this one and I started reading it...
Really cool links here, by the way...
The reason I am posting, though... is that everyone was on about "without air, there is no sound".
That is incorrect (and I am sure you guys know it, I am not playing smart ass here). Sound needs a medium, any physical medium will do. We are most familiar with sound transmission through air... but that is certainly not the ony one.
Sure... sounds made in another planet, or even by a star cannot travel to us in the traditional way - the vacuum of space means there is no physical medium, and so sound cannot travel from the source to us.
Sorry about all the rambling... let me get to the point. I believe a whole category of space sounds has been missed.
I am sure that spaceships and the International Space Station are full of noises! Even if there was no air inside them, temperature differences between the sun-lit and the "night" side should make for all sorts of creacking sounds as the ship orbits the Earth and its hull dilates and contracts with the temperature differences. Those vibrations would travel through the hull of the ship and I am sure could be picked up by contact mics.
I also read an article once about equiping space ships with vibration/sound sensors on their hulls to detect micro meteor impacts. The sensors would pick up the vibrations, and because there would be many of them on the hull, a computer on board would triangulate the position of the meteor impact, so astronauts could inspect/repair.
"without air, there is no sound"
"That is incorrect. Sound needs a medium, any physical medium will do. We are most familiar with sound transmission through air... but that is certainly not the only one."
Water would be a good example of what you're referring to here. Marine life uses sound everyday to guide their way. Dolphins, etc..
Yes, of course. Water is the other best known example.
But sounds also travel through solid objects. In this particular case, I was thinking of ship's hulls - be it manned spacecraft or unnmaned. I am sure that temperature differences would cause those ship's hulls to creak and squeak. That is a sound I do not think anyone has recorded .
And small celestial bodies like asteroids and comets would similarly produce sounds as they rotate and their surface gets baked by the sun and then plunged into space freeze.
On comets, gas vents would also be heard... although I have no idea what these would sound like... hock:
A lot of 'space' sounds are audio representations of electromagnetic disturbances or variations (a bit like false colour images). Now we know how various electromagnetic disturbances sound here on earth - so if they occur in space, they can be re-processed to mimic what they would sound like if they passed through our atmoshpere.
In the Venus recordings (made by the Russions) they heard what they thought was thunder and lightning. The recordings aren't long beause the harsh atmosphere terminated the hardware in a very short period (not long after the probe landed), but they are 'real' sound recordings based on what audio equipment they had at the time. (One of the main mission objectives on Venus, Mars and Titan was to 'listen' and record what they could hear.)
But just because in reality you can't hear sound in space doesn't mean that you can't utitlise sound. Remember all those spaceship sounds and explosions.... What would those movies have been like if they had those shots surrounded by complete silence? (remember that there are no pressure waves in space either so explosions are just lightshows and nothing more)

Speking of which... here is the link to a sound recording made by NASA's Cassini probe.
This is the electromagnetic (radio) signals generated by a massive thunderstorm in Saturn.
