wish to reveal the status of their rocketry and space capabilities. Early in his presidency, Kennedy was poised to dismantle the manned space program but postponed any decision out of deference to Johnson, who had been a strong supporter of the space program in the Senate. This quickly changed on April 12, 1961, when Soviet cosmonaut Yuri Gagarin became the first person to fly in space, reinforcing American fears about being left behind in a technological competition with the Soviet Union. Kennedy now became eager for the U.S. to take the lead in the Space Race, for reasons of national security and prestige. On April 20, he sent a memo to Johnson, asking him to look into the status of America's space program, and into programs that could offer NASA the opportunity to catch up. After consulting with Wernher von Braun, Johnson responded approximately one week later, concluding that "we are neither making maximum effort nor achieving results necessary if this country is to reach a position of leadership". His memo concluded that a manned Moon landing was far enough in the future that it was likely the United States would achieve it first. Kennedy's advisor Ted Sorensen advised him to support the Moon landing, and on May 25, Kennedy announced the goal in a speech titled "Special Message to the Congress on Urgent National Needs": ... I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the Moon and returning him safely to the Earth. No single space project in this period will be more impressive to mankind, or more important for the long-range exploration of space; and none will be so difficult or expensive to accomplish. After Congress authorized the funding, Webb began reorganizing NASA, increasing its staffing level, and building two new centers: a Launch Operations Center for the large Moon rocket northwest of Cape Canaveral Air Force Station, and a Manned Spacecraft Center on land donated through Rice University in Houston. Kennedy took the latter occasion as an opportunity to deliver another speech at Rice to promote the space effort on September 12, 1962, in which he said: No nation which expects to be the leader of other nations can expect to stay behind in this race for space. ... We choose to go to the Moon in this decade and do the other
