The National Aeronautics and Space Administration
) is the United States government
agency that is responsible for the civilian space program
as well as for aeronautics
research. President Dwight D. Eisenhower
established the National Aeronautics and Space Administration (NASA) in 1958 with a distinctly civilian (rather than military) orientation encouraging peaceful applications in space science. The National Aeronautics and Space Act
was passed on July 29, 1958, disestablishing NASA's predecessor, the National Advisory Committee for Aeronautics
(NACA). The new agency became operational on October 1, 1958. Since that time, most U.S. space exploration efforts have been led by NASA, including the Apollo moon-landing
missions, the Skylab
space station, and later the Space Shuttle
. Currently, NASA is supporting the International Space Station
and is overseeing the development of the Orion Multi-Purpose Crew Vehicle
, the Space Launch System
and Commercial Crew
vehicles. The agency is also responsible for the Launch Services Program
(LSP) which provides oversight of launch operations and countdown management for unmanned NASA launches.
Theodore Roosevelt, Jr.
(; October 27, 1858 – January 6, 1919), also known as T.R.
, and to the public (but never to friends and intimates) as Teddy
, was the twenty-sixth President of the United States
, and a leader of the Republican Party
and of the Progressive Movement
. He became President of the United States at the age of 42. He served in many roles including Governor of New York
, historian, naturalist, explorer, author, and soldier. Roosevelt is most famous for his personality: his energy, his vast range of interests and achievements, his model of masculinity, and his "cowboy" persona. Roosevelt prided himself on being a rough and tumbled man. This was partly because as a child he suffered from sever asthma. As he outgrew his ailments he took on masculine challenges such as boxing, wrestling, and of course, his favorite pastime, hunting. His last name, often mispronounced, is, per Roosevelt, "pronounced as if it were spelled "Rosavelt"— in three syllables, the first syllable as "Rose."
As Assistant Secretary of the Navy, Roosevelt prepared for and advocated war with Spain in 1898. He organized and helped command the 1st U.S. Volunteer Cavalry Regiment, the Rough Riders, during the Spanish–American War. Returning to New York as a war hero, he was elected Republican governor in 1899. He was a professional historian, a lawyer, a naturalist and explorer of the Amazon basin; his 35 books include works on outdoor life, natural history, the American frontier, political history, naval history, and his autobiography.
