On Monday, Union Minister Kiren Rijiju tweeted a video and images of the manned submersible Matsya (Hindi for Fish) 6000, which is a part of the Samudrayaan program and will explore the ocean's depths. The National Institute of Ocean Technology (NIOT), in Chennai, is creating the vessel. This will be India's first human ocean exploration mission whenever it is put into service. Aquanauts will be able to travel on the spherical vehicle as deep as 6,000 meters. The first underwater voyage, however, will only be 500 meters long. According to Mr. Rijiju, the mission won't affect the marine habitat.
