ATOMIC BOMBSSlide2

th

August: the American B29 bomber Enola Gay dropped the first atomic boy, codenamed ‘Little Boy’ on the Japanese city of Hiroshima:It exploded with a force of 20,000 TNT (chemical compound formula)The temperature at the centre of the explosion reached 3000°C - 4000°C three times hotter than volcanic lavaEverything within a mile of the centre of the blast was flattenedFires spread and around 67% of Hiroshima’s buildings were destroyed

Second atomic bomb

th August: The Americans dropped the second atomic bomb, codenamed ‘Fat Man’, on the Japanese city of NagasakiSlide4
Consequences

14

th August – The Japanese surrendered Japanese claimed a quarter of a million were killed. Many suffered horrific injuries. In the years that followed, many survivors developed ill health

Studies of the survivors have allowed doctors to understand radiation poisoning, and to set safety levels for the nuclear power industrySlide5

The Hydrogen BombSlide6

‘Ivy Mike’: The First Test

The operation, codenamed ‘Ivy Mike’, was detonated on 1

st November 1952 on an atoll in the Pacific. Following the test, the particular device was deemed unsuitable for use as a weapon.The radius of the explosion itself was approximately 3km, the mushroom cloud reached around 37km high, the crater was approximately 2km across and 164ft deep, the surrounding island were stripped of vegetation and the area was heavily contaminated for some time. Slide7

ICBMsSlide8

The Soviets used captured Nazi scientists to pioneer their Soviet rocket program.

This work was based on the Nazi V2 rocket used in the second World war.This lead to the Soviets launching their first ICBM in Kazakhstan. It was the first ICBM capable of carrying a thermo-nuclear bomb.

Slide9

This technology was highly significant leading later to the development of Sputnik- the first ever space satellite

.Slide10

ICBMs were a highly significant development due to the fact that the utilisation of this weapon required no prior planning or preparation, as planes, manual labour and infrastructure were replaced by a single button.Slide11
UK Atomic WeaponsSlide12

UK tested first atomic bomb October 1952

First hydrogen bombs tested in 1957-581958 UK/US nuclear collaboration resumed and Mutual Defence agreement signedSlide13
Operation Hurricane

3

rd October 1952, the UK became the third country to test nuclear weapons after the USA and Soviet Union. Code-named ‘Hurricane’, and was conducted at the Montebello Islands in Western Australia.Turtles killed as result of testingBased on this test, the UK developed the first deployable nuclear weapon, the Blue Danube.Tests conducted in Aborigine territory affected

AboriginiesSlide14

UK conducted last nuclear test on November 26

th 1991Signed Comprehensive Test Ban Treaty on September 24th 1996Slide15
Space RaceSlide16
Sputnik

October 4

th 1957 Soviets launched Sputnik (traveller), the world’s first artificial satelliteThis was the first man-made object to placed into earth’s orbitUnwelcome surprise to America who thought of space as a new frontier that they wanted to be the first to explore Slide17
Explorer 1

1958 USA launched own satellite, Explorer 1, designed by

Wernher von BraunPresident Eisenhower signed public order creating NASAEisenhower also created two security programmes that would operate with NASAOne programme, code-named Corona, used orbiting satellites to gather intelligence on the USSRSlide18
April 1961 Soviet Yuri Gagarin became the first man to orbit Earth

February 1962 John Glenn became the first American to orbit earth

December 1968 Apollo 8 launched, first space mission to orbit moonJuly 16th 1969 Aldrin, Armstrong, Collins landed on the moonSlide19

1975 joint Apollo-Soyuz sent three US astronauts into space aboard an Apollo aircraft that docked in orbit with Soviet vehicle

‘Hand-shake in space’ seen to be sign of improving relations
