It was a regular joint operation with an unmanned submersible, marking the "one ship, two submersibles" model's transition to the operational stage. The system will now survey hydrothermal areas and conduct research in marine geology, chemistry, biology and physics. #Jiaolong manned submersible #deep-sea program #Spring Festival Subscribe to us on YouTube: https://goo.gl/lP12gA Download our APP on Apple Store (iOS): https://itunes.apple.com/us/app/cctvnews-app/id922456579?l=zh&ls=1&mt=8 Download our APP on Google Play (Android): https://play.google.com/store/apps/details?id=com.imib.cctv For more: https://news.cgtn.com/news/2026-02-17/China-s-deep-sea-program-in-new-phase-over-Spring-Festival-1KQ7EePuOis/p.html Thu, 09 Apr 2026 05:15:20 GMT https://validator.w3.org/feed/docs/rss2.html PeerTube - https://tankie.tube https://tankie.tube/lazy-static/avatars/3ba3ff73-a8b6-49c9-add8-9653ef090c7f.webp https://tankie.tube/videos/watch/ed523ec1-1c15-4b36-8856-b69ea05f0c2a All rights reserved, unless otherwise specified in the terms specified at https://tankie.tube/about and potential licenses granted by each content's rightholder.
