Beep Beep! Sputnik — the satellite that instigated the space race — turns 55 years old today. About the size of a beach ball yet weighing 184 pounds, Sputnik 1 circled the globe every 96 minutes and made 1,440 orbits. It traveled approximately 60 million kilometers, transmitting satellite beeps all the way until it burned up on January 4, 1958. Three months later, Sputnik 2 was launched carrying a passenger dog named Laika — the first dog in space!
Enjoy this ditty from 1959 in celebration of Sputnik.
