Chandrayaan-3: Why is moon landing so difficult?

A trip to Earth's only natural satellite is still highly challenging and fraught with dangers more than 50 years after the first Apollo mission touched down there.



With the Chandrayaan-3 mission, the Indian Space Research Organisation (ISRO) will try a soft landing on the Moon once more. The mission is slated to launch from Sriharikota at 2.30 PM on July 14. The endeavour is still fairly challenging even though humans first set foot on the Moon more than 50 years ago.


When the Vikram lander collided with the Moon's surface in September 2019, the Chandrayaan-2 mission was declared a failure. A similar outcome befell the Israeli-led Beresheet expedition earlier that year. Years later, in April of this year, the Japanese Hakuto-R mission similarly failed to make a soft landing on the moon.


And these are just a few of the numerous missions that tried and failed to reach the Moon. The United States and the Soviet Union wrecked spacecraft after spacecraft during the space race in the 1960s before successfully landing one. With the Chang'e-5 mission in 2013, China became the only other nation to successfully perform a soft landing on the Moon.
