Tag, You’re It
WHEN IT GOES LIVE LATER this year, ICARUS will have two main components: antennae deployed on the International Space Station and the tags. The penny-size tech—attached as backpacks, collars, or ear tags—includes a transmitter, GPS module, thermometer, accelerometer, magnetometer, rechargeable battery, and solar cell. The ISS will pick up tiny signals from the tags each time the station passes over, an arrangement inspired by radio astronomy, which uses large antennae to pick up faint signals. Researchers can remotely reprogram the tech.
Petite Pack At 0.59-by-1by-0.35 inch, the new tag doesn’t burden this Eurasian blackbird.
