Uncovering the Titanic

MIR 1 and 2

Picture
There are many types of submersibles all over the world. The two that were used in the expeditions to uncover the Titanic were Russian vessels named MIR 1 and MIR 2. These were built to be used in scientific research and also rescue opperations.

These high tech vessels are little sphere shaped submarines  which include an outside casing made of nickel and steel that is 5cm thick. Inside the submarine themselves it is only 6.9 feet wide. The total length on the outside is about 25 feet long and they weigh 18.6 tons each.

They are able to dive to depths up to 19,860 feet deep, where pressures can reach up to about  8,583.84 pounds per square inch or 1,236,073. 61 pounds per square foot. The subs are able to dive in these extreme pressures thanks to the very strong, solid nickel and steel outsides. 
This makes them two of only five manned submersibles in the world that can dive beyond 9,840 feet. 


Another huge detail to these subs is that each vehicle has an iron-nickel battery with a capacity of 100 kilowatts, which is twice as much as is available for other submersibles in the same dive range  (19,800 feet). This battery uses the potential chemical energy inside it to change into different energies such as kinetic mechanical which allow the subs to move or kinetic thermal to heat the eight, 1,200-watt halogen-mercury-iodine lights that each sub carries. This transformation of energies which lights up the bulbs is a huge element in allowing the scientist to see in the complete darkness of the waters and to even take important footage, like that taken to be used in documentaries and movies such as the movie Titanic. Due to the battery being so large and powerful the MIR 1 and MIR 2 are able to stay submerged on dive missions for 17 to 20 hours at a time.
