There will be three spacewalks from the International Space Station today, but one of these three is not like the others. One is an old suit that will contain old clothes and a transmitter instead of a human. It is expected to circle the earth several times and eventually burn up upon re-entry.

Along with the radio transmitter, it also will have internal sensors to monitor temperature and battery power. As the empty suit floats along, it will transmit its telemetry — temperature, battery power and time it has been in space — to the ground.

On a NASA Web site, students and others can track the spacesuit's location. The suit is expected to pass once or twice a day in the U.S., between midnight and 4 a.m., according to NASA.

"We expect the ham radio operators on the ground to be able to receive the suit signal for several days," said Kwatsi Alibaruho, flight director for the spacewalk at NASA's Johnson Space Center in Houston.

Educational Trash. I like it.
