Countries with technological giants such as the United States and Russia have so far landed in the equatorial region of the moon. Because the moon's equator is the safest place with all the conditions suitable for the launch of spacecraft to return without any damage. But India did not select this region for its exploration and carried out the research by dropping the instrument called 'Moon Impact Probe' through its Chandrayaan spacecraft on the polar region of the moon, which is a challenge to the technologists of the world. India's first attempt is said to have yielded some very important information about the possibility of water on the moon and the possibility of helium-3 gases on the moon.
Next, India is trying to send a man to space and then to the moon. It is noteworthy that even if more than one country has the technology to send a man to space, only the United States has succeeded in sending a man to the moon. Although the GSLV rocket we have now can send humans into space, there are various technical challenges in sending humans into space in general. We can send humans into space only if we ensure that the operational reliability of our space technology and spacecraft is 100% safe.
If we consider space travel, the first challenge begins when we cross the Earth's atmosphere. First we have to travel in a gasless vacuum. To ensure 100 percent safety of the spaceships while traveling in such places where the temperature is low and the external pressure is high, the spaceships should have been tested by creating a vacuum on the ground. Beyond this, let's say we get close to another planet in space, the next challenge we face is the gravity of that planet. To overcome this challenge we have to accurately predict the gravity of the planet and change the speed of our spaceship accordingly, in this even if there is a small error the spaceship will be attracted by the gravity of the planet and crash into it and get destroyed. It is only after making several precise calculations that the ground can land on its surface.
When there are so many problems in sending unmanned spaceships, perhaps if we send humans in that spaceship, there will be an additional burden to overcome the above problems and protect the lives of the astronauts being sent. As long as the astronaut is inside the spaceship, various protections are provided, but even if there is a situation to get out of the spaceship, they are put on a space suit (Space Suit) for extra protection.
