NASA’s Deep Space Atomic Clock to launch into Earth’s orbit in late June

( Xinhua ) – The Deep Space Atomic Clock, a new technology from NASA’s Jet Propulsion Laboratory (JPL), will be launched on a SpaceX Falcon Heavy rocket into Earth’s orbit for one year in late June, according to a latest release of JPL.

The clock, a toaster-size device, is the first GPS-like instrument small and stable enough to fly on a spacecraft.

Currently, navigators tell a spacecraft where to go by calculating its position from Earth and sending the location data to space in a two-way relay system that can take anywhere from minutes to hours to deliver directions.

The new technology of the clock enables a spacecraft to know where it is without needing to rely on that data from Earth, according to JPL.

After deploying the clock to Earth’s orbit, engineers will test whether it can help spacecraft locate themselves in space.

If the clock’s trial year in space goes well, it could pave the way for a future of one-way navigation in which astronauts are guided by a GPS-like system across the surface of the Moon or can safely fly their own missions to Mars and beyond, said JPL.

“Every spacecraft exploring deep space is steered by navigators here on Earth. Deep Space Atomic Clock will change that by enabling onboard autonomous navigation, or self-driving spacecraft,” said mission Deputy Principal Investigator Jill Seubert.
