Answer:
On Sept. 12, 1962, the US President John F. Kennedy, gave a speech to the crowd of about 4,000 people gathered at Rice University Football Stadium in Houston, Texas, officially titled as the "Address at Rice University on the Nation's Space Effort," also known as "We Choose to go to the Moon" speech.
Explanation:
The speech was delivered to urge the Americans to support the Apollo Program. The Apollo Program was the national effort by the Government to land a man on the moon. When the Soviet Union on Oct. 4, 1957, successfully launched the first artificial satellite "Sputnik 1" it was perceived by the Americans that they were losing the Space Race. Knowing the urgency and the need for the achievement for the sake of the political gains, the US President Kennedy asked his vice president, Lyndon B. Johnson, to investigate if they can beat the Soviet Union in anyways. The cost of landing a man on the moon was calculated to be $22 billion. The goals set by Kennedy then gave vision to NASA's Apollo Program.
In his speech, Kennedy says, "We choose to go to the moon. We choose to go to the moon in this decade and do the other things, not because they are easy, but because they are hard; because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one we intend to win, and the others, too" to show the urgency so that they could win the space race beating the Soviet Union. The goal that Kennedy set was not just to land a man on the moon but "landing a man on the moon and returning him safely to Earth." Kennedy used metaphor in his speech to show the urgency and to bring change in his audience. Though the idea of joint Moon Mission was abandoned with the death of Kennedy but his goal was lived by the Americans in July 1969 with the success of Apollo 11 Moon Landing.
