The Chinese have their sights set on the high frontier, but this week they’re looking to another unexplored realm intent on setting records there too:
(Xinhuanet) — The Xiangyanghong 09 ship carrying China’s manned deep-sea submersible Jiaolong arrived at the designated dive area of the Mariana Trench on Monday morning, where it will attempt the world’s first 7,000-meter dive. The Jiaolong, depending on local weather and sea conditions, will dive six times, deeper and deeper, to try a new dive record.
The first dive will challenge the depth of over 5,000 meters, but less than 6,200 meters. The fifth and sixth dives are scheduled to challenge the depth of 7,000 meters.
That is an impressive goal, any nation or org that can pull it off should be widely applauded for coping with the design challenges in an unforgiving, ultra deep sea environment. But as noted in comments, how would a 7 km dive be a record exactly?
