Why is a soft landing on the Moon so difficult? 🚀
Nearly sixty years after the Soviet Union’s Luna 9 mission made history as the first soft landing on the Moon, a lunar landing remains elusive for many countries. Russia’s Luna-25 mission failed earlier this week, in the same year that the Japanese Hakuto mission crash-landed. In 2019, Chandrayaan-2’s crash was preceded by Israel’s Beresheet facing a similar fate.
But why is it so difficult?
To begin with, the Moon has an extremely thin atmosphere. This means that spacecraft cannot rely on atmospheric friction to slow down considerably ahead of a landing. This means that they will have to rely heavily on their propulsion systems to make a safe landing. Also, there is no GPS on the Moon, unlike here on Earth. This means that onboard computers will have to make quick calculations and manoeuvres to land at a safe location without guidance from a massive network of satellites.
Why is ISRO aiming for the southern pole?
All of the spacecraft that have landed on the Moon previously have landed in the equatorial region, either a few degrees of latitude north or a few degrees south of the lunar equator. NASA’s Surveyor 7 is the mission that went farthest from the equator in history, landing as far away as 50 degrees south of the equator.
It is not without reason that so many missions land near the equator. The terrain and temperature there are more welcoming, making the long and sustained operations of instruments easier. Also, the surface there is relatively smooth with very few steep slopes, hills and craters.
Due to the difficult environment, the polar regions of the Moon have largely remained unexplored. But if the data from many previous orbiter missions is anything to go by, there regions could be very interesting to explore. Chandrayaan-1 observed some evidence of the presence of ice molecules in the deep craters in the region.
Also, the freezing cold temperatures of the region mean that things trapped there would remain frozen for a long time. Essentially, that part of the Moon could act as a “time capsule.” This could help scientists discover clues about the early history of the solar system, including how the Earth and the Moon formed.

About Goldilocks zone:
✓It is a habitable zone, also called the “Goldilocks zone”, is the area around a star where it is not too hot and not too cold for liquid water to exist on the surface of surrounding planets.
✓Our Earth is in the Sun’s Goldilocks zone.
