One of those contributions was the invention of a remote controlled video camera sled called Argo. It was one of the most important machines in science history, because of its discovery of the RMS Titanic. This unmanned deep-sea exploration tool was three and a half feet wide, fifteen feet long, and over forty thousand pounds in weight. The Argo had several incandescent lights and multiple cameras so that the ocean floor could be lit for Ballard and his team to see. After the crew discovered possible findings, he brought out the Alvin (as shown in Figure One), a deep diving underwater vessel that could hold a small crew. Along with the Alvin, he also used the Jason Junior (as shown in Figure Two), an unmanned remote controlled small vessel that could fit through tight spaces. Ballard was in the Alvin when the machines were sent underwater to more closely observe the wreckage of the
