The Luna programme (from the Russian word Луна "Luna" meaning "Moon"), occasionally called Lunik by western media, is a series of robotic spacecraft missions sent to the Moon by the Soviet Union and later Russia between 1959 and 2023. Fifteen were successful, each designed as either an orbiter or lander, and accomplished many firsts in space exploration. They also performed many experiments, studying the Moon's chemical composition, gravity, temperature, and radiation.
Twenty-four spacecraft were formally given the Luna designation, although more were launched. Those that failed to reach orbit were not publicly acknowledged at the time, and not assigned a Luna number. Those that failed in low Earth orbit were usually given Cosmos designations. The estimated cost of the Luna programme in 1964 was US$6–10 billion.
The name Luna was used to designate a variety of spacecraft designs, to achieve several types of missions:
Lander (spacecraft)#Impactors
Impactor spacecraft are designed to hit the near side of the Moon. Luna 1 (January 1959) missed its intended impact with the Moon and became the first spacecraft to escape the Earth-Moon system. Luna 2 (September 1959) mission successfully hit the Moon's surface, becoming the first man-made object to reach the Moon. This was Luna's only impact success out of six tries from September 1958 to September 1959.
A flyby is the simplest lunar spacecraft, requiring neither a propulsion device for slowing, nor a guidance system sensitive enough to hit the Moon. Its function is to transmit photographs back to Earth. Luna 3 (October 1959) rounded the Moon later that year, and returned the first photographs of its far side, which can never be seen from Earth. This was Luna's only successful flyby, out of three tries from October 1959 to April 1960.
Soft landing (aeronautics)
Soft landers require rocket propulsion to slow their speed sufficiently to prevent the craft's destruction. They can continue to transmit pictures from the surface, and possibly dig into the lunar soil or return other information about the lunar environment.

The objective of the course is to present with different viewpoints, the lessons learned which lead to the decisions in the space exploration and their consequences today and for the decades to come.
A sample-return mission is a spacecraft mission to collect and return samples from an extraterrestrial location to Earth for analysis. Sample-return missions may bring back merely atoms and molecules or a deposit of complex compounds such as loose material and rocks. These samples may be obtained in a number of ways, such as soil and rock excavation or a collector array used for capturing particles of solar wind or cometary debris. Nonetheless, concerns have been raised that the return of such samples to planet Earth may endanger Earth itself.
Lunokhod (Луноход, "Moonwalker") was a series of Soviet robotic lunar rovers designed to land on the Moon between 1969 and 1977. Lunokhod 1 was the first roving remote-controlled robot to land on an extraterrestrial body. The 1969 Lunokhod 1A (Lunokhod 0, Lunokhod No. 201) was destroyed during launch, the 1970 Lunokhod 1 and the 1973 Lunokhod 2 landed on the Moon, and Lunokhod 3 (Lunokhod No. 205, planned for 1977) was never launched. The successful missions were in operation concurrently with the Zond and Luna series of Moon flyby, orbiter and landing missions.
Lunokhod 1 (Russian: Луноход-1 ("Moonwalker 1"), also known as Аппарат 8ЕЛ No 203 ("Device 8EL No. 203") was the first of two robotic lunar rovers landed on the Moon by the Soviet Union as part of its Lunokhod program. The Luna 17 spacecraft carried Lunokhod 1 to the Moon in 1970. Lunokhod 1 was the first remote-controlled robot "rover" to freely move across the surface of an astronomical object beyond the Earth. It was also the first wheeled craft on another celestial body. Lunokhod 0 (No.
