Roosevelt declared in a speech the next day that it was "...a day that will live in infamy".
1942: Stephen Hawking is born on Earth. He becomes one of Earth's foremost theoretical physicists, seeking to link quantum mechanics with the theory of relativity.
1945: The American nation develops and uses two nuclear devices to end Earth's devastating second world war. As a measure to maintain peace on Earth, the United Nations is chartered in the city of San Francisco on the North American Continent.
1947: July - Humans near the town of Roswell, New Mexico on Earth's North American Continent report
the discovery of an extraterrestrial spacecraft. Official government investigators later announce that the report was
mistaken and that the object sighted was a weather balloon.
October 14 - Earth test pilot Chuck Yeager becomes
the first human to fly an aircraft faster than the speed of sound in his planet's atmosphere.
1957: October 4 - First artificial satellite is launched from Earth. Sputnik I is orbited by the Soviet Union, marking the dawn of Earth's Space Age. While observing Sputnik I, a Vulcan space craft develops engine failure causing the ship to crash near Carbon Creek, Pennsylvania USA. The three surviving crew members live on Earth for three months before being rescued. Just prior to their departure, the senior officer, T'Mir, gives humans VELCRO.
1958: July 29 - American President Dwight D. Eisehhower signs the National Aeronautics and Space
Act, establishing the National Aeronautics and Space Administration (NASA).
October 1 - After merging the efforts of numerous
agencies and facilities across the United States, NASA begins operations.
1961: Piloting the space craft Vostok I, Yuri Gagarin becomes the first human to travel in space. American president John F. Kennedy commits his nation to an ambitious program to land a human on Earth's moon by the end of the decade.
1969: July 20 - Neil Armstrong becomes the first human to walk on the Earth's moon, proclaiming the historic Apollo 11 flight to be "one small step for (a) man, one giant leap for mankind". Computer pioneer Henry Starling introduces the first isograted circuit, spurring the beginning of Earth's microcomputer revolution.
1976: The American nation begins testing Earth's first reusable spacecraft, known as the Space Shuttle. The test vehicle is named Enterprise and is designated Orbiter Vehicle (OV)-101.
1981: April 12 - Space Shuttle Columbia, OV-102, is launched from Cape Canaveral, Florida for it's first successful orbital flight.
1986: January 28 - Seven astronauts, one of them a teacher, are killed when the Space Shuttle Challenger, OV-099, is destroyed by an explosion 73 seconds after liftoff. It is considered by some as the worst disaster for NASA since the Apollo 1 fire on January 27, 1967.
1992: The Eugenics Wars begin when a group of genetically bred "supermen" seize control of one quarter of Earth, plunging the planet into a terrible conflict. (Fortunately, Los Angeles is spared destruction.)
1996: The Eugenics Wars come to end as the genetic tyrants are overthrown. One "superman", Khan Noonien Singh, along with a number other "supermen" and "superwomen" loyal to him, escapes into space aboard the S.S. Botany Bay, an experimental spacecraft. Earth scientists announce discovery of a possible micro fossil from Mars, the first physical evidence of life from another world.
1999: NASA launches the Voyager 6 spacecraft. Some time in the future, the craft falls into a black hole and emerges on the other side of the galaxy. The probe encounters a planet populated by living machines, which enhances the craft so it can return home.
