Check out some of the biggest, boldest and best moon missions of all time in this countdown.
FIRST STOP: Soviet Luna 2

Luna 2This unmanned Soviet probe became the first man-made object to make contact with another planetary body. The spherical spacecraft launched on Sept. 12, 1959 and impacted the moon two days later.

Luna 3This Soviet follow-up to the first moon impactor became the first spacecraft to take pictures of the far side of the moon. The spacecraft launched Oct. 4, 1959.

Ranger 7This U.S. spacecraft captured about 4,300 images of the lunar surface — the first high-quality photos sent back from the moon. It later crashed landed in the Sea of Clouds. It launched July 28, 1964

Luna 9This unmanned Soviet probe became the first to make a controlled landing on the lunar surface. On Feb. 3, 1966, Luna 9 touched down into a moon crater, and then sent back panoramic images of the landscape.

Luna 10Racking up another Soviet first, this mission became the first man-made object to successfully orbit another celestial body. The unmanned probe launched March 31, 1966, and entered orbit around the moon two days later. Over two months, the spacecraft circled the moon 460 times and continuously transmitted readings.

Surveyor 1In June 1966, the United States accomplished what the Soviets had four months earlier, by successfully landing a probe on moon in a controlled manner. Over a six-week mission, Surveyor 1 snapped over 11,100 images of the lunar surface.

Lunar Orbiter 5This U.S. mission was part of a series of unmanned lunar prospecting missions in preparation for the manned Apollo landings. Upon completion of the Lunar Orbiter 5 mission, the moon's surface had been 99 percent mapped. The spacecraft launched Aug. 1, 1967, and completed its mission on January 31, 1968.

Apollo 8On Dec. 21, 1968, NASA astronauts Frank Borman, James Lovell, and William Anders became the first humans to leave low-Earth orbit and visit the moon. They arrived in lunar orbit on Christmas Eve, Dec. 24, 1968, and sent back the famous first human views of Earth rising from the horizon of the moon. After 10 orbits of the moon, the three astronauts headed back to Earth and landed on Dec. 27, 1968.

Apollo 11The United States made up for its slow start in the space race with the Soviets by grabbing the ultimate prize: landing the first man on the moon. NASA astronauts Neil Armstrong and Buzz Aldrin stepped down on the Sea of Tranquility on July 20, 1969, while their crewmate Michael Collins orbited above in the Apollo Command and Service Module. The three returned home on July 24, 1969.

Luna 16In between American Apollo manned flights, the Soviet Union launched this unmanned sample return mission to the moon on Sept. 12, 1970. Luna 16 landed on the lunar surface (in total darkness, no less), collected moon rocks, packed them up, and returned them to Earth. It was the first successful robotic sample return.

Lunokhod 1The Soviet Lunokhod 1 was the first lunar rover to traverse the moon. The rover launched unmanned on Nov. 10, 1970 as part of the Luna 17 mission. After touching down on the moon, the remote-controlled vehicle traveled over 6 miles (10.5 kilometers), snapping photos and video the whole way.

Luna 24The Soviet Lunokhod 1 was the first lunar rover to traverse the moon. The rover launched unmanned on Nov. 10, 1970 as part of the Luna 17 mission. After touching down on the moon, the remote-controlled vehicle traveled over 6 miles (10.5 kilometers), snapping photos and video the whole way.

Lunar ProspectorThis NASA unmanned spacecraft launched Jan. 7, 1998 on a mission to orbit the moon in search of signs of water ice and other minerals in permanently shaded craters at the lunar poles. Over the course of 19 months, the probe compiled a map of the mineral composition over the surface, before crash landing on July 31, 1999.

SMART-1This mission represented the first lunar mission entrée from the European Space Agency. The unmanned SMART-1 probe launched on Sept. 27, 2003, and reached lunar orbit in November 2004. The small spacecraft was powered by ion engine using solar electric energy.

Kaguya (SELENE)This Japanese mission to the moon lifted off Sept. 14, 2007, and entered orbit around the moon less than a month later. The spacecraft is still in lunar orbit, compiling the most detailed map yet of the moon's gravitational field.

Chang'e 1China's first mission beyond Earth launched Oct. 24, 2007. The unmanned spacecraft orbited the moon until March 2009, when it was intentionally crashed into the lunar surface. China followed that mission with the Chang'e 2 probe, which launched on Oct. 1, 2010 and only recently left the moon to travel to the L1 Lagrange Point between the Earth and the sun.

Chandrayaan-1Not to be outdone, India joined the moon exploration game on Oct. 22, 2008, when it launched the robotic Chandrayaan-1 probe to lunar orbit. India's first mission beyond Earth, the probe observed the moon from orbit until August 2009. In November 2008, the spacecraft released the Moon Impact Probe to slam into the moon, ejecting dirt that might reveal traces of lunar water ice. In September 2009, results from one of Chandrayaan-1's instruments, the Moon Mineralogy Mapper, helped detect evidence for water on the moon.

Lunar Reconnaissance OrbiterLRO was NASA's first moon mission since the Apollo era. The unmanned orbiter launched on June 18, 2009. Originally planned as a precursor to manned American return trips to the moon, LRO has been mapping the lunar surface in high-resolution 3-D. The probe has good enough vision to spot footprints from the Apollo astronauts. LRO launched with the LCROSS mission designed to hunt for water on the moon.

Lunar Crater Observation and Sensing Satellite (LCROSS)Launched to the moon with LRO, the LCROSS mission succeeded in confirming the presence of water on the moon after it crashed into the lunar surface. The $79 million spacecraft impacted the moon's south pole as it took pictures of its descent.

GRAILNASA's twin GRAIL spacecraft are due to launch Sept. 8, 2011 on a mission to study the lunar gravitational field from orbit to learn more about the moon's formation and history. The two spacecraft will take an energy-efficient route to polar orbit around the moon, planning to arrive on Dec. 31, 2011. Researchers plan to monitor slight changes in the distance between the two probes caused by variations in the moon's gravitational field.

Chang'e 3 and Yutu RoverLaunched in December 2013, China's Chang'e 3 moon landing mission marked the country's first-ever landing on another celestial body. It landed on Dec. 14 carrying the Yutu rover - another China first - and is the first soft-landing on the moon in 37 years, following the former Soviet Union's Luna 24 in 1976.

The six-wheeled Yutu rover is a solar-powered vehicle equipped with cameras, a robotic arm tipped with science gear and a radar system attached to its underbelly.
