India’s first manned deep-sea mission, Samudrayaan, has hit a timeline setback due to delays in receiving syntactic foam cladding from France. The foam is essential for providing buoyancy to the submersible MATSYA 6000, which is designed to dive 6,000 metres into the ocean. The mission is led by the National Institute of Ocean Technology (NIOT), Chennai under the Ministry of Earth Sciences.
