The hatch of the Jiaolong, a Chinese manned submersible, opened at 10:13 am Beijing time, returning after having successfully reached a depth of 5,057 meters at 6:12 am.
The test dive, which commenced at 3:38 am today in international waters of the Pacific Ocean, achieved complete success, the State Oceanic Administration (SOA) said.
Ye Cong, Yang Bo and Fu Wentao were the members of the three-man crew.
Such a depth means the Jiaolong is capable of reaching over 70 percent of the seabeds in the world, said the SOA.
The SOA said the submersible is slated for a 7,000-meter test dive in 2012.
The Jiaolong is the world's first manned submersible designed to reach the depth of 7,000 meters below sea level, according to Xu Qinan, chief designer of the submersible.
Xu said the Jiaolong's equipment was state of art and its digital underwater communication systems and undersea mobility systems allowed the craft to "move back and forth easily under the sea."
The domestically-manufactured Jiaolong, named after a mythical sea dragon, dived to a depth of 4,027 meters with three people aboard in about five hours last Thursday. But its attempt to reach 5,000 meters in another dive on Friday was postponed due to unfavorable sea conditions.
The craft completed 17 dives in the South China Sea from May 31 to July 18 last year, with the deepest reaching 3,759 meters with three crew members on board.
China, initiating the Jiaolong project in 2002, is the fifth country to send a man 3,500 meters below sea level, following the United States, France, Russia and Japan.
