Scientific objectives of the Apollo 17 mission included, geological surveying and sampling of materials and surface features in a preselected area of the Taurus-Littrow region; deploying and activating surface experiments; and conducting in-flight experiments and photographic tasks during lunar orbit and transearth coast.

Command Module Pilot Ken Mattingly orbited the Moon while astronauts John Young and Charlie Duke were on its surface. Apollo 16's landing spot was chosen in order to gather geologically older lunar material. Charlie Duke left a picture of his family on the site.

Apollo 15 was the first of the Apollo "J" missions capable of a longer stay time on the moon and greater surface mobility. There were four primary objectives falling in the general categories of lunar surface science, lunar orbital science and engineering-operational.

The primary objectives of this mission were to explore the Fra Mauro region centered around deployment of the Apollo Lunar Surface Scientific Experiments Package, or ALSEP; lunar field geology investigations; collection of surface material samples for return to Earth.

The Apollo 13 lunar landing was aborted after an oxygen tank in the service module failed two days into the mission. The story of Apollo 13 is an enduring tale of survival, perseverance and innovation in the face of emergency.

The primary mission objectives of the second crewed lunar landing included an extensive series of lunar exploration tasks by the lunar module, or LM, crew, as well as the deployment of the Apollo Lunar Surface Experiments Package, or ALSEP, which was to be left on the moon's surface to gather

The primary objective of Apollo 11 was to complete a national goal set by President John F. Kennedy on May 25, 1961: perform a crewed lunar landing and return to Earth.

The Apollo 10 mission encompassed all aspects of an actual crewed lunar landing, except the landing. It was the first to operate around the Moon. Objectives included a scheduled eight-hour lunar orbit of the separated lunar module, or LM, and descent to about nine miles off the Moon's surface before
