UPDATE! SuitSat1 is not dead - it's just transmitting at a low power. From Bil Munsil comes the following info:

"SuitSat1 is still alive and ham operators and other folks all around the world are receiving the audio, telemetry and SSTV picture.

"Go to http://www.aj3bu/blog/ to listen in."

So, they tossed an empty spacesuit out of the International Space Station earlier today, and it's out there orbiting the planet, but the radio transmitter they stuck in there that many were hoping they'd be able to listen to on their police scanners apparently went dead.

From SpaceWeather.com:

Space is cold - apparently too cold for SuitSat's batteries. The Earth-orbiting spacesuit stopped transmitting shortly after it was thrown overboard from the International Space Station on Feb. 3rd. Probable cause: lack of power.

This doesn't mean that SuitSat was a failure. The experimental satellite was "launched" to answer questions such as "Can a spacesuit-satellite function without internal temperature controls?" The answer, apparently, is "no." Next-generation SuitSats will take this into account.

SuitSat will continue to orbit Earth for weeks, spiraling slowly into the atmosphere. Stay tuned for information about seeing SuitSat in the night sky.
