Sammy the Second – Deep Space Atomic Clock Project

A new video from NASA’s Jet Propulsion Laboratory in Pasadena, Calif., uses an engaging animated character named “Sammy the Second” to explore the value and potential impact of the innovative Deep Space Atomic Clock project — a NASA Technology Demonstration Mission to revolutionize deep-space navigation.

The 4-minute video illustrates the role of time in calculating explorers’ positions — from early seafarers who circumnavigated the globe using clocks and the stars, to modern, satellite-based global positioning systems and deep-space radio navigation systems. It explains how the Deep Space Atomic Clock will demonstrate — during a space mission planned for 2015 — use of a small, mercury-ion atomic clock at least an order of magnitude more accurate than today’s best navigation clocks.
