The Phoenix mission, originally planned for three months on Mars, now is in its fifth month. However, it faces a decline in solar energy that is expected to curtail and then end the lander's activities before the end of the year. Before power ceases, the Phoenix team will attempt to activate a microphone on the lander to possibly capture sounds on Mars.

Hopefully, it will be capable of hi-fi, not space shuttle audio.

Not Likely, I wonder why they waited so long to Activate that package.

If there isn't any air on Mars, then the microphone won't hear anything! Tongue

Are FETs supposed to glow like that?

There's windstorms... so there must be "air"...

Maybe not oxygen rich, and breathable to humans....

Didn't Bugs Bunny and that martian with the broomstick on his helmet have a theme song? Be great if they heard that.....

The solar conjunction (when the Earth passes between Mars and the sun) begins on Nov. 18th and lasts until Dec. 24th. During that time, the Earth will appear to be a mere speck on the face of the sun. No transmitter made by man can outstrap the sun, so the probe will be unable to receive any further orders from us. Even though it won't hear us for 5 weeks, we will still be able to hear it.

That leaves only a small amount of time to perform a whole lot of work with only a certain available bandwidth at only a certain available power level. The work they had originally planned for the probe comes first, any followup work based on those results comes second, and novelties with little scientific value come last, just before the uplink blackout.

After that, they only have until about Feb. 2 before the probe becomes encased in CO2 ice, which won't melt again until late Nov. 2009 at the earliest, when the sunlight goes back over 16 hours per martian day. Most likely the batts will be completely spent by then, and may not accept a charge again.

But hey, given the hellacious environment it's been in for the last 5 months, it's a small miracle it's even still operational.

I wonder if the lander uses a Q-36 Explosive Space Modulator........

(probly not, that creature stole the space modulator!)

Buggsy would turn blue.
Don't you remember Ahhnold's bulging eyeballs? Great movie; combined undercover agent thriller and realistic possiblility of a future Mars colony.. until they discovered the ancient alien atmosphere generator.  Now that was a rig!

Ave. pressure is about 7 millibars compared to the 1000 nominal on earth. About the same as cruising at 100,000 ft. or so.  But in deference to Al it is almost 100% C02.  -- just his kind of climate too, very cold and very dry.  Just a note; since Mars gravity is what, 0.38 of Earth's?, then the pressure gradient is much more gradual than Earth's.  That 7 millibars goes a long way  Grin

So I hear if you stood in one of the dust devils swirling around a typical Martian desert, you'd get sand blasted by the very fine iron oxide, silica and salt /mineral particles.  

They've actually photographed a couple in action as well as the tracks on the surface where dust devils have roamed.

"Oh give me a home...."
  "Where the dust devils roam..."
"Where the skys are not cloudy all day..."
  Uh, salmon pink, actually.

Is there Illudium Pu-36 on Mars?
