Construct a timeline of the manned mission to space.

On October 4, 1957, the former Soviet Union (Russia) launched the world's first artificial satellite, Sputnik I.  This inaugural launch ushered in man's efforts to conquer space as a frontier.  At that time, the United States had no organized space program.  On July 29, 1958, the National Aeronautics and Space Administration (NASA) became America's united front to contend with the Soviet Union in what later became known as the "Great Space Race."  The soviet Union...

On October 4, 1957, the former Soviet Union (Russia) launched the world's first artificial satellite, Sputnik I.  This inaugural launch ushered in man's efforts to conquer space as a frontier.  At that time, the United States had no organized space program.  On July 29, 1958, the National Aeronautics and Space Administration (NASA) became America's united front to contend with the Soviet Union in what later became known as the "Great Space Race."  The soviet Union led the United States in a memorable list of "firsts" in the effort to leave the earth and explore the existence of space.  Here is a short list of notable step-wise accomplishments:

• April 12, 1961, Yuri Gagarin is the first human to enter space.


• May 5, 1961, Alan Shepard is the first American to enter space.


• August 6, 1961, Gherman Titov spends first day in space.


• February 20, 1962, John Glenn achieves first orbital flight in space.


• August 11, 1962, Andrian Nikolayev achieves first four day flight with group in space.


• October 3, 1962, Walter Schirra achieves first American 6 orbit flight in space.

• June 16, 1963, Valentina Tereshkova becomes first woman in space.

The list is quite intricate and extensive, I have provided a reference link for you to check.  The "race" between the Soviet Union and the United States had a major climactic reversal in the Soviet lead when the United States was successful on July 20, 1969, in landing a three-man crew on the moon.  Current space travel efforts include missions to Mars and the discovery of other planets within our solar system.
