Apollo 17 was the sixth and final manned mission to the Moon as part of NASA's Apollo program, launched in December 1972. ## Overview In the early 1970s, the United States was racing against the Soviet Union for space supremacy. The Apollo program, initiated in 1961, aimed to land humans on the Moon by the end of the decade. After five successful missions, Apollo 17 marked the culmination of this ambitious endeavor. This mission carried a crew of three experienced astronauts: Eugene Cernan, Ronald Evans, and Harrison Schmitt. Their mission objectives included conducting scientific experiments, deploying seismometers, and exploring the lunar surface. Apollo 17 was the first and only mission to include a professional geologist, Harrison Schmitt, who conducted in-depth observations of the lunar geology. The crew also had the luxury of a longer stay on the Moon, with 75 hours and 48 minutes spent in lunar orbit and 22 hours and 48 minutes spent on the lunar surface. The extended mission allowed for more extensive scientific exploration and the deployment of a lunar rover. The Apollo 17 spacecraft consisted of three main components: the Command Module (Casper), the Service Module, and the Lunar Module (Challenger). The Lunar Module was designed to separate from the Command Module and land on the Moon's surface. The mission's success was heavily reliant on the precise coordination of the Lunar Module's descent engine and the Command Module's orbital trajectory. ## History/Background The Apollo program began in 1961 with President John F. Kennedy's goal to land humans on the Moon before the end of the decade. The first Apollo mission, Apollo 8, was launched in December 1968, followed by several successful missions, including Apollo 11, which achieved the first lunar landing in July 1969. Apollo 17 was originally planned to be the ninth mission, but was reassigned as the sixth mission due to a series of delays and technical issues. The mission's crew was selected in 1970, with Harrison Schmitt joining Eugene Cernan and Ronald Evans. The Apollo 17 spacecraft was launched on December 7, 1972, from Kennedy Space Center's Launch Complex 39A. ## Key Information * **Mission Timeline**: Apollo 17 was launched on December 7, 1972, and landed on the Moon's surface on December 11, 1972. The crew spent three days conducting scientific experiments and exploring the lunar surface before returning to Earth on December 19, 1972. * **Lunar Surface Activities**: The Apollo 17 crew conducted three extravehicular activities (EVA), with a total of 22 hours and 48 minutes spent on the lunar surface. They deployed seismometers, lunar surface drills, and collected over 250 pounds of lunar samples. * **Scientific Discoveries**: The Apollo 17 mission made several significant scientific discoveries, including the identification of a previously unknown type of lunar rock, the detection of moonquakes, and the observation of the lunar horizon using the Lunar Surface Gravimeter. * **Lunar Rover**: Apollo 17 was the first mission to use a lunar rover, which allowed the crew to cover greater distances and collect more samples. * **Command Module**: The Command Module, Casper, was the largest and most sophisticated Command Module built for the Apollo program. ## Significance Apollo 17 marked the culmination of the United States' Apollo program, demonstrating the country's technological capability and pushing the boundaries of space exploration. The mission's success was a testament to the hard work and dedication of the thousands of individuals involved in the program. The Apollo 17 mission provided invaluable scientific data and insights into the Moon's geology, composition, and internal structure. The crew's observations and samples have enabled scientists to better understand the Moon's formation and evolution. The Apollo 17 mission also paved the way for future space exploration, demonstrating the feasibility of long-duration spaceflight and the importance of human presence in space.

Apollo 15 was the ninth manned mission to land on the Moon, launched on July 26, 1971, and marked a significant milestone in the United States' Apollo program. ## Overview Apollo 15 was a groundbreaking spaceflight mission that took place in July 1971, during the height of the Apollo program. The mission was crewed by three astronauts: David R. Scott, James B. Irwin, and Alfred M. Worden. Apollo 15 was the first mission to use the Lunar Roving Vehicle (LRV), a battery-powered, four-wheeled vehicle designed to facilitate mobility on the lunar surface. The mission's primary objectives were to conduct extensive scientific experiments, collect samples, and explore the lunar surface in greater detail than previous missions. The Apollo 15 spacecraft was launched from Kennedy Space Center's Launch Complex 39A on July 26, 1971, at 9:08 a.m. EDT. The mission was crewed by Commander David R. Scott, Lunar Module Pilot James B. Irwin, and Command Module Pilot Alfred M. Worden. The spacecraft consisted of two main components: the Command and Service Module (CSM) "Endeavour" and the Lunar Module (LM) "Falcon." The CSM was responsible for carrying the crew to the Moon and back to Earth, while the LM was used for lunar landing and surface operations. ## History/Background The Apollo 15 mission was the culmination of years of planning, development, and testing. The mission's concept was first proposed in 1968, and the spacecraft was designed and built by NASA's Marshall Space Flight Center in Huntsville, Alabama. The LRV was developed by the United States' aerospace industry, with contributions from companies such as Boeing, General Motors, and North American Rockwell. The mission's scientific payload included a range of instruments designed to study the lunar surface, atmosphere, and subsurface. The Apollo 15 mission was also notable for its crew. Commander David R. Scott was a veteran astronaut who had previously flown on Gemini 8 and Apollo 9 missions. Lunar Module Pilot James B. Irwin was a geologist and astronaut who had been selected for the Apollo program in 1966. Command Module Pilot Alfred M. Worden was a physicist and astronaut who had flown on Apollo 9 and was scheduled to command the Apollo 19 mission before being grounded due to a medical issue. ## Key Information Apollo 15 was a highly successful mission that achieved all of its primary objectives. The LRV was used extensively on the lunar surface, allowing the astronauts to travel a total distance of 17.5 miles (28.2 kilometers) and conduct a range of scientific experiments. The mission's scientific payload included a lunar surface magnetometer, a lunar surface gravimeter, and a lunar surface seismometer. The astronauts also collected over 170 pounds (77 kilograms) of lunar samples, which were brought back to Earth for further study. One of the most significant achievements of the Apollo 15 mission was the deployment of the Lunar Surface Magnetometer (LSM). The LSM was a sensitive instrument designed to measure the lunar surface's magnetic field, which was expected to be very weak. However, the instrument detected a surprisingly strong magnetic field, which was later found to be caused by the presence of iron-rich minerals in the lunar regolith. ## Significance The Apollo 15 mission marked a significant milestone in the United States' Apollo program, demonstrating the capabilities of the LRV and the scientific potential of lunar exploration. The mission's success paved the way for future lunar missions, including the Apollo 16 and Apollo 17 missions, which also used the LRV. The Apollo 15 mission also highlighted the importance of scientific experimentation and sample return in space exploration, which has become a key aspect of modern space missions.
