A day after we first reported on Argentina's missing submarine, the ARA San Juan, officials from the Argentine Navy have stated that the vanished vessel had tried to make contact with Argentine naval bases on no less than seven separate occasions on Saturday. The calls, which were made via satellite, came between 10:52am and 3:42pm and lasted from as short as four seconds to as long as 36 seconds. A connection was never made but communications companies from the U.S. are working to try to geolocate the position from where the calls were made.
