History of America's Space Program
Inception of the Space Program
The United States' journey into space exploration began during the height of the Cold War, as a response to the Soviet Union's successful launch of the first artificial satellite, Sputnik, on October 4, 1957. This event spurred the U.S. government into action, primarily due to the military and geopolitical implications of space technology and the perceived missile gap between the U.S. and the Soviet Union.
In response, the U.S. Congress passed the National Aeronautics and Space Act, which President Dwight D. Eisenhower signed into law on July 29, 1958. This act created the National Aeronautics and Space Administration (NASA), a centralized agency to handle all non-military space activity. NASA officially began operations on October 1, 1958.
Apollo Missions: Successes and Failures
The Apollo program was the centerpiece of NASA's efforts to achieve manned lunar landing and exploration. Initiated in 1961, the program was driven by President John F. Kennedy's ambitious goal of "landing a man on the Moon and returning him safely to the Earth" by the end of the decade. Below is a table summarizing each Apollo mission, including dates, outcomes, and notable achievements or incidents:
Mission | Date | Outcome | Notable Achievements/Incidents |
Apollo 1 | January 27, 1967 | Failure | Fatal cabin fire during a launch rehearsal test. |
Apollo 7 | October 11-22, 1968 | Successful | First crewed Apollo mission; Earth orbital mission to test the command and service module. |
Apollo 8 | December 21-27, 1968 | Successful | First humans to orbit the Moon. |
Apollo 9 | March 3-13, 1969 | Successful | Earth orbital mission to test the lunar module. |
Apollo 10 | May 18-26, 1969 | Successful | "Dress rehearsal" for lunar landing, orbiting the Moon. |
Apollo 11 | July 16-24, 1969 | Successful | First manned Moon landing. |
Apollo 12 | November 14-24, 1969 | Successful | Precision landing on the Moon's Ocean of Storms. |
Apollo 13 | April 11-17, 1970 | Successful (Failure) | Successful failure; returned crew safely after an oxygen tank explosion. |
Apollo 14 | January 31-Feb 9, 1971 | Successful | Alan Shepard hit two golf balls on the Moon. |
Apollo 15 | July 26-Aug 7, 1971 | Successful | First use of the Lunar Roving Vehicle. |
Apollo 16 | April 16-27, 1972 | Successful | Explored the lunar highlands. |
Apollo 17 | December 7-19, 1972 | Successful | Last manned Moon landing; included a geologist as crew member. |
Discontinuation of the Apollo Program
The Apollo program was discontinued after Apollo 17, primarily due to budgetary constraints and shifting public and governmental priorities. The immense cost of the program, combined with the achievement of its main objective (the Moon landing) and the lack of additional compelling goals at that time, led to the decision to allocate resources to other types of missions, such as the Skylab space station, which was the next major step in NASA's manned spaceflight.
The technological, scientific, and geopolitical achievements of the Apollo missions had a lasting impact on science and engineering and established the U.S. as a leader in space exploration during the 20th century. The legacies of these missions continue to influence NASA's direction, particularly in plans for returning to the Moon and future manned exploration of Mars.
Russian Space Program
The Chief Designer: Sergei Korolev
Backwards engineered the German V2 Rocket (pioneered by Werner Van Braun) and developed the R1 rocket, which was a vastly improved version of the V2. This was first launched in 1942 with a range of 270km, about 780 km farther than the V2.
The R2 doubled the range along with,
- Changed the fuel from Ethyl Alcohol to Methyl Alcohol, allegedly in part because the launch troops had taken to drinking the fuel.
- Lengthened the fuel tanks
- Improved the propellant turbo pumps
Eventually a test flight of the R7 launched the first satellite, Sputnik, in 1957.
