NASA Triggers A Deep Space Atomic Clock - TNBC UK

For making a revolution in a deep-space navigation, Nasa has put a miniaturized atomic clock in orbit. The device, with a size of a toaster, is considered to have the stability of 50 times of existing space clocks as those flown in GPS satellites.

If the technology manifests itself over the next year, NASA will implement the clock in future planetary probes. The timepiece was one of the 24 separate establishments from a Falcon Heavy rocket that introduced from Florida on Tuesday.

The other passengers on the flight were substantially also demonstrators. They added a small spacecraft for testing the latest type of “green” rocket fuel, and another platform which targets to drive itself via the pressure of sunlight caught in a large membrane, what is often introduced a “light sail”.

But it is the mercury-ion atomic clock, developed at the Jet Propulsion Laboratory, which has had the most attention.

Today, deep-space probes are trailed across the Solar System via radio signals. These signals are sent from Earth and are urgently returned by the spacecraft. The very accurate time take for the speed-of-light messages to return echo back makes enable navigators for working out the exact position of the mission and to command the necessary course corrections.  But if probes carried their own atomic clocks, this two-way system could be shrunk to one way, and the mission’s onboard systems would then make all the essential navigational calculations.
