IMAGE: The Apollo 15 Mission

The Apollo 15 mission was the first mission designed to explore the Moon over longer periods, greater ranges and with more instruments for the collection of scientific data than on previous missions. The mission included the introduction of a $40,000,000 lunar roving vehicle that reached a top speed of 16 kph (10 mph) across the Moon's surface.

The successful Apollo 15 lunar landing mission was the first in a series of three advanced missions planned for the Apollo program. The primary scientific objectives were to observe the lunar surface, survey and sample material and surface features in a preselected area of the Hadley-Apennine region, setup and activate surface experiments and conduct in-flight experiments and photographic tasks from lunar orbit.

A total of three moon walks occurred during Apollo 15 for a combined duration of 18 hours and 33 minutes. Commander David Scott and Lunar Module Pilot James Irwin completed the first of the extended lunar scientific expeditions dubbed the J-series.

Apollo 15 televised the first lunar liftoff and recorded a walk in deep space by Alfred Worden. The scientific payload taken to the Moon was double the previous missions.

November 7, 1962 - July 13, 1974

The Apollo program was an American spaceflight endeavor that landed the first humans on Earth's Moon. Conceived during the presidency of Dwight D. Eisenhower and conducted by NASA, Apollo began in earnest after President John F. Kennedy's May 25, 1961 special address to a joint session of Congress declaring a national goal of "landing a man on the Moon" by the end of the decade.

This goal was accomplished with the Apollo 11 mission on July 20, 1969 when astronauts Neil Armstrong and Buzz Aldrin landed on the Moon, while Michael Collins remained in lunar orbit. Five subsequent Apollo missions also landed astronauts on the Moon, the last in December 1972. In these six Apollo spaceflights, twelve men walked on the Moon. These are the only times humans have landed on another celestial body.[3]
The Apollo program ran from 1961 until 1975, and was the US civilian space agency's third human spaceflight program (following Mercury and Gemini). Apollo used Apollo spacecraft and Saturn launch vehicles, which were later used for the Skylab program and the joint American-Soviet Apollo-Soyuz Test Project. These subsequent programs are thus often considered part of the Apollo program.

The program was accomplished with only two major setbacks. The first was the Apollo 1 launch pad fire that resulted in the deaths of astronauts Gus Grissom, Ed White and Roger Chaffee. The second was an oxygen tank rupture on Apollo 13 during the moonward phase of its journey, which disabled the command spacecraft. The three astronauts aboard narrowly escaped with their lives, thanks to the efforts of flight controllers, project engineers, backup crew members and the skills of the astronauts.

Apollo set major milestones in human spaceflight. It stands alone in sending manned missions beyond low Earth orbit; Apollo 8 was the first manned spacecraft to orbit another celestial body, while Apollo 17 marked the last moonwalk and the last manned mission beyond low Earth orbit. The program spurred advances in many areas of technology incidental to rocketry and manned spaceflight, including avionics, telecommunications, and computers. Apollo sparked interest in many fields of engineering and left many physical facilities and machines developed for the program as landmarks. Many objects and artifacts from the program are on display at locations throughout the world, notably in the Smithsonian's Air and Space Museums.

Wikipedia Summary of missions

U.S. Mission Booster Crew Launched Mission Goal Mission Result
AS-201 Saturn 1B Unmanned February 26, 1966 Suborbital Partial Success - Unmanned suborbital flight was the first test flight of Saturn 1B and of the Apollo Command and Service Modules; problems included a fault in the electrical power system and a 30 percent decrease in pressure to the service module engine 80 seconds after firing.
AS-203 Saturn 1B Unmanned July 5, 1966 Earth orbit Success - fuel tank behavior test and booster certification - informally proposed later as Apollo 2, this name was never approved.
AS-202 Saturn 1B Unmanned August 25, 1966 Suborbital Success - command module reentry test successful, even though reentry was very uncontrolled. Informally proposed as Apollo 3, this name was never approved.
AS-204 (Apollo 1) Saturn 1B Virgil I. "Gus" Grissom, Edward White, Roger B. Chaffee (Launch cancelled) Earth orbit Failure - never launched: command module destroyed and three astronauts killed on 27 January 1967 by fire in the module during a test exercise - Retroactively, the mission's name was officially changed to "Apollo 1" after the fire. Although it was scheduled to be the fourth Apollo mission (and despite the fact that NASA planned to call the mission AS-204), the flight patch worn by the three astronauts, which was approved by NASA in June 1966, already referred to the mission as "Apollo 1"
Apollo 4 Saturn V Unmanned November 9, 1967 Earth orbit Success - first test of new booster and all elements together (except lunar module), successful reentry of command module
Apollo 5 Saturn 1B Unmanned January 22, 1968 Earth orbit Success - first flight of lunar module (LM); multiple space tests of LM, no command or service module flown; no controlled reentry. Used the Saturn 1B originally slated for the cancelled manned AS-204 ("Apollo 1") mission
Apollo 6 Saturn V Unmanned April 4, 1968 Earth orbit Partial success - severe oscillations during orbital insertion, several engines failing during flight, successful reentry of command module (though mission parameters for a 'worst case' reentry scenario could not be achieved)
Apollo 7 Saturn 1B Walter M. "Wally" Schirra, Donn Eisele, Walter Cunningham October 11, 1968 Earth orbit Success - eleven-day manned Earth orbit, command module testing (no lunar module), some minor crew and illness issues (all three men caught the same head-cold and reported stress).
Apollo 8 Saturn V Frank Borman, Jim Lovell, William A. Anders December 21, 1968 Lunar orbit Success - ambitious mission profile (changed relatively shortly before launch), first human lunar orbit (no lunar module), first earthrise seen by men and major publicity success, some minor sleeping and illness issues
Apollo 9 Saturn V James McDivitt, David Scott, Russell L. "Rusty" Schweickart March 3, 1969 Earth orbit Success - ten-day manned Earth orbit, with EVA and successful manned flight / docking of lunar module
Apollo 10 Saturn V Thomas P. Stafford, John W. Young, Eugene Cernan May 18, 1969 Lunar orbit Success - second manned lunar flight; first test of lunar module in lunar orbit; "dress rehearsal" for first landing, coming to 8.4 nautical miles (15.6 km) to the Moon's surface
Apollo 11 Saturn V Neil Armstrong, Michael Collins, Edwin E. "Buzz" Aldrin July 16, 1969 Lunar landing Success - first manned landing on the Moon (manual landing required), exploration on foot in direct vicinity of landing site; one EVA

Apollo 13 Saturn V Jim Lovell, Jack Swigert, Fred Haise April 11, 1970 Lunar landing Partial Failure [30] - early shutdown of inboard S-II engine; unrelated oxygen tank rupture in service module during Earth-Moon transition caused mission to be aborted - crew took temporary refuge in the lunar module and returned safely to Earth after a single pass around the Moon.

Apollo 16 Saturn V John W. Young, Ken Mattingly, Charles Duke April 16, 1972 Lunar landing Success - malfunction in a backup yaw gimbal servo loop almost aborted landing (and reduced stay duration in lunar orbit by one day for safety reasons); only mission to target lunar highlands; malfunction prevented controlled ascent stage impact after jettison; 3 lunar EVAs plus deep space EVA
