NASA data shows less than 60 percent of all lunar missions successful



The Chandrayan-2 mission plan for the soft landing of the Vikram module on the lunar surface did not go according to scenario. The success rate of lunar missions undertaken over the last six decades is less than 60 percent, according to NASA's "Moon Fact Sheet". Of the 109 lunar missions during the period, 60 were "successful" and the rest, nearly 45 percent, were either "unsuccessful" or classified as "partial success". ISRO also issued a statement saying that nearly 95 percent of Chandrayan-2's mission objectives were met.

NASA provides tabular data on the moon's mission from the 1950s to April 2019, compared to Israel's Bereshet mission, which also distinguishes it as the first attempt to land the moon by a private company. The status of the Chandrayan-2 mission has not yet been updated on the NASA website at the time of writing. The mission is still ongoing, and although some of its goals, i. the landing of the Vikram module and the deployment of the Prague Rover have not gone according to plan, the Chandrayaan-2 orbit has yet to achieve its mission. He is currently in lunar orbit, ISRO said.

Vikram Land lost communication with ground stations during its final descent. ISRO officials said they added that the orbit of Chandrayan-2 ̵

1; the second lunar mission – remains safe and secure.

ISRO, in an update to its Chandrayaan-2 microsite, stated: "The Chandrayan-2 mission was an extremely complex mission, a significant technological leap compared to previous ISRO missions that combined Orbiter, Lander and Rover to explore the unexplored southern the pole of the moon. Success criteria have been set for each phase of the mission and so far 90 to 95 percent of the mission's goals have been achieved and will continue to contribute to lunar science, regardless of the loss of communication with Lander. [..] "

G Madhavan Nair, former chairman of ISRO, during which Chandrayaan-1 was launched a decade ago stated that the mission had achieved 95 percent of its objectives, although the farmer had not touched. A lunar mission to India in 2008 had detected the presence of water molecules on a withered lunar surface. Former NASA astronaut Jerry Linner said that the lessons learned from India's "bold attempt to soften the earth" would be to help the country during my future missions.

This year Israel also released its moon mission Beresheet in February, but it crashed landed in April.

From 1958 to 2019, India, as well as the US, USSR (now Russia), Japan, the European Union, China and Israel launched different lunar missions – from orbits, landings and flying (moon orbit, moon landing and flight) Moon)

The first mission to the moon was planned by the US on August 17, 1958, but the launch of Pioneer 0 was unsuccessful. The first successful mission to the moon is Moon 1 from the USSR on January 4, 1959. This is also the first Moon Fly mission. Success came only in the sixth mission.
In the span of just over a year, from August 1958 to November 1959, the US and USSR began 14 missions.

Of these, only three – Luna 1, Luna 2 and Luna 3 – were successful. All were launched by the USSR.
The Ranger 7 mission, launched in July 1964 by the United States, was the first close-up photo of the moon.

The first moon landing and the first images of the moon's surface came. from Moon 9, launched by the USSR in January 1966.

Five months later, in May 1966, the United States successfully launched a similar Surveyor-1 mission.

The Apollo 11 mission was the most important mission for the first time humans passed on the moon's surface. The three-crew mission is led by Neil Armstrong.

From 1958 to 1979, only the United States and the USSR began moon missions. During these 21 years, the two countries have launched 90 missions. There was a lull during the decade that followed without lunar missions from 1980-89.

Japan, the European Union, China, India and Israel were late contributors. Japan launched Hiten, an orbital mission in January 1990. It was also Japan's first moon mission. Then, in September 2007, Japan launched Selene, another orbital mission.

From 2000-2009, there were six lunar missions – Europe (Smart-1), Japan (Selene), China (Chang & # 39; e 1), India (Chandrayaan-1), and the United States (Lunar) Reconnaissance Orbiter and LCCROSS). From 2009-2019, ten missions were launched, five of which were sent from India, three from the United States and one each from India and Israel.

Since 1990, the United States, Japan, India, the European Union, China and Israel have launched 19 lunar missions.
