ISRO’s Vikram Sarabhai Space Centre (VSSC) and the National Institute of Ocean Technology (NIOT) have successfully developed India’s first personnel sphere for the Samudrayaan mission—a 2.1-meter titanium capsule designed to carry three humans to 6,000 meters deep in the ocean. Using advanced Electron Beam Welding (EBW), the complex 7.1-meter weld was completed in just 32 minutes, after 700 trial runs. The capsule passed non-destructive tests like TOFD and PAUT. Certified to withstand 600 bar pressure at -3°C, the sphere will now be integrated into the Matsya 6000 submersible for upcoming sea trials under India’s Deep Ocean Mission. (PC: NIOT)
