The International Space Station is going to host soon the most accurate clock ever sent into space. The clock could help reveal changes in nature's fundamental constants. According to the 'New Scientist', the atomic clock will allow for better synchronization of clocks on Earth and probe exotic physics too. It will keep track of time by measuring the frequency of microwaves absorbed by cooled cesium atoms. The European Space Agency (ESA) has announced that the experiment called 'Atomic Clock Ensemble in Space' will be built by EADS Atrium and is scheduled to fly to the space station in 2014.
