Question: Information: - The National Aeronautics and Space Administration (NASA ) is an independent agency of the executive branch of the United States federal government responsible for the civilian space program as well as aeronautics and aerospace research. - James Alton "Jim" McDivitt (born June 10, 1929), (Brig Gen, USAF, Ret.), is an American former test pilot, United States Air Force pilot, aeronautical engineer, and NASA astronaut who flew in the Gemini and Apollo programs. He commanded the Gemini 4 flight during which Edward H. White performed the first U.S. spacewalk, and later the Apollo 9 flight which was the first manned flight test of the Lunar Module and the complete set of Apollo flight hardware. He later became Manager of Lunar Landing Operations and was the Apollo Spacecraft Program Manager from 1969 to 1972. - A test pilot is an aviator who flies new and modified aircraft in specific maneuvers, known as flight test techniques or FTTs, allowing the results to be measured and the design to be evaluated. - The United States Navy (USN) is the naval warfare service branch of the United States Armed Forces and one of the seven uniformed services of the United States. The U.S. Navy is the largest, most capable navy in the world, with the highest combined battle fleet tonnage. The U.S. Navy has the world's largest aircraft carrier fleet, with ten in service, two in the reserve fleet, and three new carriers under construction. The service has 323,792 personnel on active duty and 108,515 in the Navy Reserve. It has 274 deployable combat vessels and more than 3,700 aircraft in active service . - Roger Bruce Chaffee (February 15, 1935 January 27, 1967), (Lieutenant Commander, United States Navy), was an American naval officer and Naval Aviator, aeronautical engineer, and NASA astronaut in the Apollo program. - Gemini 4 (officially Gemini IV) was the second manned space flight in NASA's Project Gemini, occurring in June 1965. It was the tenth manned American spaceflight (including two X-15 flights at altitudes exceeding ). Astronauts James McDivitt and Edward H. White, II circled the Earth 66 times in four days, making it the first US flight to approach the five-day flight of the Soviet Vostok 5. The highlight of the mission was the first space walk by an American, during which White floated free outside the spacecraft, tethered to it, for approximately 20 minutes. Both of these accomplishments helped the United States overcome the Soviet Union's early lead in the Space Race. - Aerospace is the human effort in science, engineering and business to fly in the atmosphere of Earth (aeronautics) and surrounding space (astronautics). Aerospace organisations research, design, manufacture, operate, or maintain aircraft and/or spacecraft. Aerospace activity is very diverse, with a multitude of commercial, industrial and military applications. - Aeronautics (from the ancient Greek words "r", which means "air", and "nautik" which means "navigation", i.e. "navigation into the air") is the science or art involved with the study, design, and manufacturing of air flight capable machines, and the techniques of operating aircraft and rockets within the atmosphere. The British Royal Aeronautical Society identifies the aspects of "aeronautical Art, Science and Engineering" and "the profession of Aeronautics (which expression includes Astronautics)." - Edward Higgins '' Ed '' White II ( November 14 , 1930 -- January 27 , 1967 ) , ( Lt Col , USAF ) , was an American aeronautical engineer , U.S. Air Force officer , test pilot , and NASA astronaut . On June 3 , 1965 , he became the first American to '' walk '' in space . White died along with his fellow astronauts Virgil '' Gus '' Grissom and Roger B. Chaffee during prelaunch testing for the first manned Apollo mission at Cape Canaveral . He was awarded the NASA Distinguished Service Medal for his flight in Gemini 4 and then awarded the Congressional Space Medal of Honor posthumously . - An aircraft is a machine that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. What entity does 'edward higgins white' has the relation 'military branch' with?
Answer:
united states air force
