Yan Kai, the chief engineer of China's manned deep-sea submersible research vessel Jiaolong, confirmed that the craft will reach a depth of 7,000 meters below sea level this summer, thereby meeting its design goals. The submersible has successfully completed all of its previous trial runs, carrying three crewmembers to a depth of more than 4,000 meters below sea level and subsequently to a depth of 5,038 meters.
