Submerged rigid repeater for Transatlantic Telephone cable

In 1956 the first transatlantic telephone cable, TAT-1, was laid. In the section connecting Newfoundland and Nova Scotia rigid electronic repeaters were included to boost the electrical signals sent through the cable. Another section of the cable connecting Newfoundland and Oban, Scotland used flexible repeaters developed by Bell Telephone Laboratories.

J-2 Engine

The J-2 Engine was used in the second and third stages of the Saturn V rocket. Five were used in the second stage and one relight-able one was used in the third stage. Each engine produced 232,250 lbs of thrust in a vacuum which pushed the Saturn V into orbit at 17,400 mph and then onto the Moon at over 24,000 mph.
