Mir (submersible)

A mir submersible is like a little underwater car that people can ride in to explore deep parts of the ocean. It has a strong metal shell to keep the people inside safe from the water pressure, and it's connected to a big ship on the surface by a long cable that gives it power and communication. The submersible has special lights so the people inside can see, and it has cameras so they can take pictures and videos of all the cool things they see down there, like fish, plants, and even shipwrecks! It's like going on an adventure, but underwater!
