The spacecraft is a “dual-spin” design — a controlled spin keeps Galileo stable. One section of the spacecraft rotates at 3rpm. On this section, six instruments rapidly gather data from many different directions. The other section of the spacecraft holds steady for the four instruments that must point accurately while Galileo is flying through space. (NASA)
