Moon Missions: Welcome back to "Science For Everyone", ABP Live's weekly science column. Last week, we discussed the reasons why Chandrayaan-2 failed, and what changes the Indian Space Research Organisation (ISRO) had made to ensure the success of Chandrayaan-3. As the country rejoices at the historic soft landing of Chandrayaan-3 on the Moon's south pole, we discuss this week all the successful lunar missions launched till date. 


On August 23, 2023, India became the first country in the world to softly land a spacecraft on the lunar south pole. Chandrayaan-3 is India's third lunar exploration mission, and is expected to operate till the first week of September 2023. 


Check all the stories appearing in ABP Live's weekly science column here.


Successful Moon Missions Launched Till Date


A total of 146 Moon missions have been launched till date. Of these, over 75 missions have been successful. India's Chandrayaan series started in 2008, and NASA's Apollo program began in 1968. Luna 2 is the first successful Moon mission. 


The following is the list of successful and operational Moon missions which achieved firsts and made groundbreaking discoveries.


Luna 2


Launched on September 12, 1959, by the Soviet Union, Luna 2 was the second spacecraft in the Luna series, and the first spacecraft to land on the Moon. Its landing site was near the lunar surface east of Mare Serenitatis near the Aristides, Archimedes, and Autolycus craters, according to NASA. With this, the Soviet Union became the first country to land a spacecraft on the Moon. 


The design of Luna 2 was similar to that of Luna 1. It was a spherical spacecraft. Luna 2 found no evidence of radiation belts on the Moon, and confirmed that the Moon has no magnetic field.

Luna 3


Luna 3 was the second spacecraft to reach the Moon, and the first to return images of the far side of the Moon. It was launched on October 4, 1959. The images revealed mountainous terrain on the far side of the Moon, and two dark regions.


Ranger 7


Launched on July 28, 1964, by NASA, Ranger 7 was a huge milestone for the United States because it was the country's first successful lunar mission after 13 consecutive failures. 


The spacecraft captured 4,316 images of the Moon, according to NASA. However, it crashed into the Moon on the northern edge of the Sea of Clouds, or Mare Nubium, a lunar mare located in the Moon's near side. With the help of the images captured by Ranger 7, NASA identified safe Moon landing sites for Apollo astronauts.

Ranger 8


NASA launched Ranger 8 on February 17, 1965. The spacecraft impacted the Moon's surface on February 20, 1965. Ranger 8 captured over 7,000 high-resolution images of the lunar surface before its impact on the Sea of Tranquility, a lunar region that was thoroughly studied by Apollo mission planners. 


Ranger 9


Ranger 9 was the last in the series of NASA's Ranger spacecraft launched in the 1960s. Its aim was to take images as it descended towards the lunar surface for impact. The spacecraft was different from its predecessors in the fact that it pointed its cameras in the direction it was heading. It was launched on March 21, 1965.

Zond 3


Zond 3 was launched on July 18, 1965, from Tyuratam, now Baikonur Cosmodrome. It captured pictures of the Moon's far side. The spacecraft's science objects were to study the ultraviolet and infrared spectra of the lunar surface, magnetic properties of near-Earth and interplanetary space, cosmic rays, low-frequency galactic radiation, solar wind, and micrometeorites. It captured images of the remaining 30 per cent of the lunar far side. 


Luna 9


Launched on January 31, 1966, Luna 9 was the first spacecraft to achieve a soft landing on the Moon, and the first to transmit photographic data from the Moon's surface to Earth. The Soviet Union's Luna 9 proved that the surface of the Moon could support the weight of a lander, and that an object would not sink into the lunar surface.

Zond 7


Zond 7 was launched on August 7, 1969. Its aim was to obtain coloured photographs of the Earth and Moon from varying distances. 


Apollo 12


The Apollo 12 mission launched astronauts Charles "Pete" Conrad Jr, Apan Bean, and Richard F Gordon Jr towards the Moon on November 14, 1969. The astronauts blasted off towards the Moon atop a Saturn V rocket. 


Just after launch, the Apollo 12 spacecraft was struck twice by lightning. Though this temporarily knocked out electrical power, the problems did not stop a successful mission. 


The goals of Apollo 12 included investigation of the lunar surface environment, and enhancement of the capability for human lunar exploration. 


The Apollo 12 crew deployed an instrument package and collected more than 34 kilograms of samples, captured photographs of the lunar surface, collected samples of the solar wind, and investigated soil mechanics.

Apollo 13


Apollo 13, which was supposed to land in the Fra Mauro area of the Moon, was forced to circle the Moon without landing because an explosion occurred onboard the spacecraft. The crew included astronauts John Swigert, Fred Haise, and James Lowell. While it was supposed to be the third lunar landing attempt, Apollo 13 was aborted after a service module oxygen tank ruptured. However, the crew returned safely to Earth, and NASA gained a lot of experience in rescuing the crew, because of which Apollo 13 is known as a "successful failure". The mission was launched on April 11, 1970, and returned to Earth after six days, on April 17, 1970.

Apollo 15


Astronauts David R Scott, James B Irwin, and Alfred M Worden were the crew members of Apollo 15, the fourth mission in which humans walked on the Moon. Apollo 15 marked the first time humans drove on the Moon. 


The astronauts were launched towards the Moon on July 26, 1971. 


Apollo 15 doubled the time spent on the lunar surface, compared to the previous record-holder, Apollo 14. 


The goals of Apollo 15 included exploring the mountainous Hadley-Apennine region, making engineering evaluations of new Apollo equipment, activating lunar surface scientific experiments, photography, and conducting experiments related to lunar orbit.


The Apollo 15 astronauts, with the help of the first automotive vehicle designed for off-planet use, explored a more diverse region of the Moon than ever before.

Luna 20


Luna 20, launched on February 14, 1972, soft landed on the Moon in a mountainous region known as the Apollonius highlands near the Sea of Fertility. 


Apollo 16


Astronauts John W Young, Charles M Duke Jr, and Thomas K Mattingly were launched towards the Moon on April 16, 1972, as part of the Apollo 16 mission. At that time, scientists believed that lunar highlands were of volcanic origin. The findings of Apollo 16 proved these assumptions wrong.


Apollo 16 was the first crewed landing in the central lunar highlands. Astronauts made the first spacewalk during the return journey to Earth, as part of Apollo 16. 


Though Apollo 16 was the fifth mission in which astronauts walked on the surface of the Moon, it was far from routine. This is because it changed the way scientists think of the Moon.


John W Young, the commander of the mission, and Charles M Duke, pilot of the lunar module "Orion", landed at the western edge of the Descartes mountains on the Moon, on April 21, 1972. 


The command module "Casper" was piloted by Thomas K Mattingly, who also performed experiments in lunar orbit. 


The destination for Apollo 16 was different from those for the previous Apollo missions. Three of the destinations were in mare regions, which are flat, dark plains of lower elevation on the Moon, also referred to as lunar seas.


The measurements made and samples collected by Apollo 16 astronauts disproved the hypothesis that the central lunar highlands on the lunar surface were a product of volcanic eruptions in the Moon's ancient past.

PFS-2


PFS-2 was deployed from the Apollo 16 service module in lunar orbit to study the Moon's plasma and particle environment. It was launched on April 16, 1972. 


Apollo 17


Apollo 17 was the last time humans landed on the Moon. Astronauts Eugene A Cernan, Ronald E Evans, and Harrison H Schmitt were launched towards the Moon on December 7, 1972, atop a Saturn V rocket, as part of the Apollo 17 mission. The crew reached the lunar surface on December 11, 1972. 


The astronauts collected the oldest known unshocked lunar rock. This suggests that the Moon had a dynamo-generated magnetic field in its past. This is a magnetic field generated by a fluid inside an astronomical object.


The crew collected samples of "orange soil" containing volcanic glass, and deployed scientific experiments.

They left a plaque on the Moon which reads: "Here man completed his first exploration of the Moon, December 1972 A.D. May the spirit of peace in which he came be reflected in the lives of all mankind".


Apollo 17 was the first mission in which a scientist got the opportunity to investigate the Moon firsthand.


Harrison H Schmitt was a geologist and had been part of the backup crew for Apollo 15. He served as pilot of the lunar module, "Challenger", for Apollo 17. 


The command module, "America", was piloted by Ronald E Evans. Eugene A Cernan was the commander of Apollo 17.

The Orion spacecraft returned to Earth on December 12, 2022, after spending over 25 days in the harsh environment of deep space. Orion splashed down in the Pacific Ocean, after circling a path of more than 2.25 million kilometres around the Moon. 


The aim of Artemis I was to test Orion in the harsh environment of deep space before flying astronauts on Artemis II. 


Chandrayaan-3


Chandrayaan-3, India's third lunar exploration mission, was successfully launched on July 14, 2023. About 40 days after launch, Chandrayaan-3 successfully soft-landed on the Moon's south pole on August 23, 2023, at 6:02 pm IST, making India the first country to softly land a spacecraft on the lunar south pole. 


The Pragyan rover successfully rolled out of the Vikram lander over four hours after the historic touchdown. Chandrayaan-3 has shared images captured during lunar descent, and pictures of the landing site, with Earth.

According to ISRO, the rover rolled out of the lander with the help of a two-segment ramp, and used the power generated by a solar panel. 


All of Chandrayaan-3's activities are on schedule, and all systems are normal. Three of the lander's payloads — Chandra's Surface Thermophysical Experiment (ChaSTE), Instrument for Lunar Seismic Activity (ILSA), and Radio Anatomy of Moon Bound Hypersensitive ionosphere and Atmosphere (RAMBHA) — have been turned on. Both the payloads of the rover — Alpha Particle X-ray Spectrometer (APXS) and Laser Induced Breakdown Spectroscope (LIBS) — have also been turned on. The rover mobility operations have commenced.

On August 26, Prime Minister Narendra Modi declared August 23 as National Space Day. He has named the landing site of Chandrayaan-3 as 'Shiv Shakti Point'. 


Chandrayaan-3 has accomplished two of its mission objectives: demonstration of safe and soft landing on the lunar surface, and demonstration of roving the Moon. 


Both Vikram and Pragyan's rovers are performing normally, and in-situ scientific experiments are being conducted. Therefore, the third objective is expected to be achieved about 14 days from touchdown.
