In an address to Congress, U.S. president John F. Kennedy announced his support for the Apollo program, with "the goal, before this decade is out, of landing a man on the Moon and returning him safely to the Earth".

A joint session of the United States Congress is a gathering of members of the two chambers of the bicameral legislature of the federal government of the United States: the Senate and the House of Representatives. Joint sessions can be held on any special occasion, but are required to be held when the president delivers a State of the Union address, when they gather to count and certify the votes of the Electoral College as the presidential election, or when they convene on the occasion of a presidential inauguration. A joint meeting is usually a ceremonial or formal occasion and does not perform any legislative function, and no resolution is proposed nor vote taken.

John Fitzgerald Kennedy, also known as JFK, was the 35th president of the United States, serving from 1961 until his assassination in 1963. He was the first Roman Catholic and youngest person elected president at 43 years. Kennedy served at the height of the Cold War, and the majority of his foreign policy concerned relations with the Soviet Union and Cuba. A member of the Democratic Party, Kennedy represented Massachusetts in both houses of the United States Congress prior to his presidency.

The Apollo program, also known as Project Apollo, was the United States human spaceflight program led by NASA, which landed the first humans on the Moon in 1969. Apollo was conceived during Project Mercury and executed after Project Gemini. It was conceived in 1960 as a three-person spacecraft during the Presidency of Dwight D. Eisenhower. Apollo was later dedicated to President John F. Kennedy's national goal for the 1960s of "landing a man on the Moon and returning him safely to the Earth" in an address to Congress on May 25, 1961.
