JFK reminds the public of the progress the United States has made since the founding of the country and reminds us of the rise to global power. Kennedy goes on to suggest space exploration, saying: "The open vistas of space surely promise high costs and difficulties, as well as high rewards." The condensation of history accomplishes two things. First, it gives listeners or readers an idea of ​​how much the United States has actually accomplished in a short time as a country. Second, it gives confidence and hope to the public, leading them to wonder what the United States can achieve in “two more years.” Maybe the United States could put a man on the Moon and beat the Soviets to the next frontier. However, achieving space exploration was impossible, without the support of the country, and this discourse and persuasion of openness is essential to convince the country to join space.
