tracking suits...
no, i didn’t mean to write “track suit” :-) the astronauts on the ISS will be releasing a used astronaut’s spacesuit filled with a radio and sensors into orbit. according to NASA’s suitsat page explains how the russian cosmonauts came up with the idea of stuffing “three batteries, a radio transmitter, and internal sensors to measure temperature and battery power” into used (and, one assumes, retired) spacesuits. using a police scanner (hmm, now, who’d have one of those?) or a ham radio one can tune in: 145.990 MHz FM :-)
now, if we could just release all suits into space…
