NASA's Deep Space Atomic Clock leaves Earth on June 24th

NASA JPL's Deep Space Atomic Clock , the navigation clock that could lead to self-driving spacecraft, is finally heading to space . The toaster-sized device will fly on the Orbital Test Bed satellite, which will be ferried to orbit along with two dozen other military, government and research satellites aboard a SpaceX Falcon Heavy rocket on June 24th, 2019. It took two decades for JPL scientists to develop the technology, making sure it's 50 times more accurate than GPS clocks and that it'll be only off by 1 second every 10 million years.
