Deep Space Atomic Clock — Navigation Breakthrough
The Deep Space Atomic Clock will revolutionize the way we conduct deep-space navigation by enabling a spacecraft to calculate its own timing and navigation data in real time. This one-way navigation technology would improve upon the current two-way system in which information is sent to Earth, requiring a ground team to calculate timing and navigation and then transmit it back to the spacecraft. A real-time, onboard navigation capability is key to improving NASA’s capabilities for executing time critical events, such as a planetary landing or planetary “flyby,” when signal delays are too great for the ground to interact with the spacecraft during the event.
