H-Bomb&Sputnik

Tension #3

The Cold War had many tensions, the first was space. The USA and USSR wanted to beat each other to who could be the first in space. The Soviet Union successfully launched Sputnik on October 4, 1957. The world's first artificial satellite was about the size of a beach ball and it marked the start of the space age. After the USSR successfully made the A-bomb, the US needed something stronger. On May 12, the United States exploded the hydrogen bomb on an island in the Pacific. The hydrogen bomb is so much powerful than the regular atomic bomb. It is the most destructive bomb that has ever been invented. The hydrogen bomb was dropped on Hiroshima and Nagasaki, Japan.
