As an expert in the field of space exploration, I can provide a detailed account of what happened to Apollo 16. Apollo 16 was a pivotal mission in the history of human spaceflight, marking the fifth successful landing on the lunar surface and the second use of the Lunar Roving Vehicle (LRV). This mission was launched on April 16, 1972, and it was the last in a series of manned missions to the Moon conducted by NASA's Apollo program.

The primary objective of Apollo 16 was to explore the lunar highlands, an area that had not been visited by previous missions. The highlands are characterized by their lighter color and are believed to be older than the lunar maria (the dark, flat areas filled with basaltic lava). The mission aimed to gather geological samples, conduct scientific experiments, and further our understanding of the Moon's composition and history.

The Apollo 16 crew consisted of Commander John W. Young, Lunar Module Pilot Charles M. Duke Jr., and Command Module Pilot Thomas K. Mattingly II. The mission began with a successful launch from Kennedy Space Center's Launch Complex 39A. After a three-day journey to the Moon, the spacecraft entered lunar orbit and the Lunar Module (LM), named "Orion," separated from the Command and Service Module (CSM), named "Casper."

On April 21, 1972, Young and Duke descended to the Moon's surface in Orion, while Mattingly remained in lunar orbit aboard Casper. The landing site was in the Descartes Highlands, an area rich in scientific interest due to its unique geological features. The astronauts spent about 71 hours on the lunar surface, during which they conducted three extravehicular activities (EVAs), or moonwalks.

During their time on the Moon, Young and Duke collected over 95 kilograms of lunar samples, including rocks and soil. They also deployed several scientific instruments, such as the Lunar Seismic Profiling Experiment (LSPE), which was designed to measure the thickness of the lunar crust, and the Lunar Surface Gravimeter Experiment, which was used to measure the Moon's gravitational field.

One of the most notable aspects of the Apollo 16 mission was the use of the Lunar Roving Vehicle. This rover allowed the astronauts to travel greater distances and gather more samples than would have been possible on foot. The LRV was also equipped with a television camera, which provided live coverage of the astronauts' activities on the lunar surface, offering the world a unique view of the mission.

The mission was not without its challenges. The astronauts faced difficulties with the Lunar Roving Vehicle, including a stuck fender and a broken fender extension, which had to be repaired during the EVAs. Despite these issues, the mission was considered a success, and the data and samples collected contributed significantly to our understanding of the Moon.

Apollo 16 concluded with a safe return to Earth on April 27, 1972, when the CSM splashed down in the Pacific Ocean. The mission's success was a testament to the skill and determination of the astronauts and the engineers who supported them.

In summary, Apollo 16 was a critical mission that expanded our knowledge of the Moon's geology and provided valuable experience in lunar exploration. The mission's achievements have left a lasting legacy in the field of space exploration and continue to inspire future generations of scientists and astronauts.
