LAFAYETTE, La. (AP) — A cubical satellite small enough to sit on the palm of your hand is zipping around the world and sending data about radiation to the Louisiana students who designed and built it.

The satellite, called CAPE-3, carries a chip designed and built by students at the University of Louisiana at Lafayette to detect radiation, with an eye to keeping astronauts safe.
