60% of lunar missions in the last 60 years have failed: NASA data sheet

NEW DELHI: the success ratio of the lunar missions undertaken in the last six decades is 60%, according to the "Moon Fact Sheet" of the US space agency NASA. Of the 109 lunar missions during the period, 61 were successful and 48 failed, he said.

In the early hours of Saturday, the plan of the Indian space agency Isro to soften the Vikram module of Chandrayaan-2 on the lunar surface did not go as expected.

The lander lost communication with the ground stations during its final descent. Isro officials said, adding that the Chandrayaan-2 orbit – second lunar mission – remains healthy and safe.

This year, Israel also launched its Beresheet lunar mission in February 2018, but crashed in April.

From 1958 to 2019, India, as well as the United States, the USSR (now Russia), Japan, the European Union, China and Israel have launched several lunar missions: orbiter, lander and flyby (in orbit around the Moon, landing on the Moon and flying from the moon).

The first mission to the Moon was planned by the United States on August 17, 1958, but the launch of Pioneer 0 was unsuccessful.

The first successful mission on the Moon was the Moon 1 of the USSR on January 4, 1959. It was also the first "Moon flyby" mission. Success came only in the sixth mission.

In the space of just over a year, from August 1958 to November 1959, the United States and the USSR launched 14 missions.

Of these, only three – Luna 1, Luna 2 and Luna 3 – were successful. All were launched from the USSR.

The Ranger 7 mission launched by the United States in July 1964 was the first to take close-up pictures of the Moon.

The first soft lunar landing and the first lunar surface images came from Luna 9, launched from 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 reference mission through which humans ascended the lunar surface. The three-member mission was led by Neil Armstrong.

From 1958 to 1979, only the United States and the USSR launched lunar missions. In these 21 years, the two countries have launched 90 missions. There was a pause in the decade that followed without lunar missions between 1980 and 1989.

Japan, the European Union, China, India and Israel have entered late.

Japan launched Hiten, an orbiter mission in January 1990. This was also Japan's first lunar mission. Later, in September 2007, Japan launched Selene, another orbiter mission.

There were six lunar missions from 2000 to 2009: Europe (Smart-1), Japan (Selene), China (Chang & # 1; and 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.
