Apollo 17, launched on December 7, 1972, was NASA's final lunar mission of the Apollo program. Led by Commander Eugene Cernan and Harrison Schmitt, it set multiple records including the longest surface stay and most extensive moonwalks in the program's history.

The final chapter of NASA's groundbreaking Apollo program came to a close with Apollo 17 in December 1972. This historic mission marked the end of an era that saw humans walk on the Moon and forever changed our understanding of space exploration.

Led by Commander Eugene Cernan and Lunar Module Pilot Harrison Schmitt, Apollo 17 achieved several milestones during its 12-day journey. The mission featured the longest lunar surface stay of the Apollo program and the most extensive moonwalks ever conducted. As Cernan climbed back into the lunar module for the final time, he left humanity's last footprints on the Moon - footprints that remain undisturbed to this day.

Apollo 17, launched on December 7, 1972, marked the last mission of NASA's Apollo program. The mission demonstrated the peak of lunar exploration capabilities with advanced scientific experiments and the most extensive surface operations.

The Apollo 17 spacecraft landed in the Taurus-Littrow valley on December 11, 1972. The mission set multiple records:

Record Category	Achievement
Surface Stay	75 hours, 21 minutes
EVA Duration	22 hours, 4 minutes
Lunar Samples	243.7 pounds (110.5 kg)
Distance Driven	22.3 miles (35.9 km)

The crew conducted three EVAs (Extra-Vehicular Activities) on December 11, 12 and 13. They deployed scientific experiments including the Surface Gravimeter, Seismic Profiling Experiment and Lunar Atmospheric Composition Experiment.

The Apollo 17 crew consisted of three experienced astronauts:

• Commander Eugene Cernan led his second lunar mission after serving on Apollo 10
• Command Module Pilot Ronald Evans orbited the Moon for a record 148 hours
• Lunar Module Pilot Harrison Schmitt became the first scientist-astronaut to walk on the Moon

Apollo 17's groundbreaking mission established multiple records for lunar exploration while generating significant scientific discoveries that expanded understanding of the Moon's composition and history.

The Apollo 17 crew completed three extensive moonwalks totaling 22 hours 4 minutes - the longest cumulative EVA time of any Apollo mission. Each EVA featured strategic exploration of the Taurus-Littrow valley:

• EVA 1: 7 hours 12 minutes exploring the valley floor
• EVA 2: 7 hours 37 minutes investigating the South Massif
• EVA 3: 7 hours 15 minutes examining the North Massif

The Lunar Roving Vehicle covered 22.3 miles (35.9 km), collecting samples from diverse geological formations across the landing site.

• Orange soil discovery at Shorty Crater, indicating ancient volcanic activity
• Collection of 243.7 pounds (110.5 kg) of lunar materials, including:
• Deep core samples reaching 10 feet (3 meters) below surface
• Ancient highland material dated to 4.2 billion years
• Deployment of ALSEP science station featuring:
• Surface Gravimeter for monitoring moonquakes
• Lunar Atmospheric Composition Experiment measuring trace gases
• Heat Flow Experiment documenting lunar thermal properties

Scientific Achievement	Measurement
Total Sample Mass	243.7 lbs (110.5 kg)
Core Sample Depth	10 ft (3 m)
Sample Age Range	Up to 4.2 billion years
Area Explored	22.3 miles (35.9 km)

NASA concluded the Apollo program in 1972 due to a combination of financial pressures, changing political priorities, and evolving space exploration objectives. The decision reflected broader shifts in American space policy and public sentiment during the early 1970s.

The Apollo program's funding declined significantly from its peak of $4.7 billion in 1966 to $1.8 billion in 1972. President Nixon's administration faced economic challenges including inflation, the Vietnam War expenses, and domestic social programs that competed for federal resources. Congress reduced NASA's overall budget by 42.6% between 1966-1972, making continued lunar missions financially unsustainable.

Year	Apollo Program Budget (Billions)
1966	$4.7
1972	$1.8

NASA redirected its focus toward more cost-effective space initiatives following Apollo 17. The agency prioritized three key projects:

• Development of the Space Shuttle program for regular Earth orbit missions
• Creation of the Skylab space station for extended orbital research
• Planning of international cooperation missions like the Apollo-Soyuz Test Project

The shift aligned with NASA's strategic goals of establishing permanent space infrastructure rather than continuing single-mission lunar expeditions. These new programs promised practical applications including satellite deployment, scientific research platforms, and improved international space relations.

Apollo 17's final mission marked the end of an era in space exploration while establishing enduring benchmarks for future lunar missions. The mission's achievements continue to influence modern space programs through its technological innovations scientific discoveries.

Apollo 17's technological advancements shaped future space missions in multiple areas. The mission's Lunar Roving Vehicle design influenced modern planetary exploration vehicles like NASA's Mars rovers. Scientific instruments developed for Apollo 17, including the Traverse Gravimeter Experiment, established protocols for geological surveys on extraterrestrial surfaces. The mission's sample collection techniques, which gathered 243.7 pounds of lunar material, created standards for extraterrestrial material handling implemented in current Mars sample return missions.

Apollo 17 Impact Metrics	Value
Lunar samples collected	243.7 lbs
Scientific experiments	12
Total EVA duration record	22 hrs 4 min
Distance traveled on surface	22.3 miles

Apollo 17 generated lasting cultural touchstones that resonate decades later. The iconic "Blue Marble" photograph, taken during the mission, became a symbol of environmental awareness showing Earth in full view from space. Eugene Cernan's final footprints inspired books, documentaries "The Last Man on the Moon" documentary showcases this legacy. The mission's technical achievements appear in educational curricula nationwide, teaching students about space exploration achievements. Popular media references Apollo 17 in productions exploring humanity's space endeavors, including "From the Earth to the Moon" HBO series.

Cultural Impact Elements	Examples
Media productions	15+ documentaries
Educational programs	200+ university courses
Museum exhibitions	50+ permanent displays
Photo reproductions	1M+ copies distributed
