India again flew towards the moon


India is ready to take another giant leap in the space world. Scientists of the Indian Space Research Organization are working hard day and night to make Chandrayaan-3 mission a reality. This mission is associated with research activities related to safely landing equipment on the surface of the Moon and thereafter obtaining as much information as possible about the Moon, Earth’s only natural satellite. Chandrayaan-3 is the mission after Chandrayaan-2. Before that Chandrayaan-1 was successfully completed by ISRO. Chandrayaan-2 was India’s second moon mission. It used a completely indigenous Orbiter, Lander (Vikram) and Rover (Pragyan). Chandrayaan-2 had for the first time identified the presence of water on the lunar surface and brought India a proud and leading position on the global stage. This information was also given great importance by the major space agencies of the world including NASA of America.

Chandrayaan-3 is India’s third mission to the moon. If all conditions are favourable, Chandrayaan-3 will be launched on July 14. As such, ISRO has prepared a window between July 13 and 19 for its launch. According to scientists, the launch of Chandrayaan-3 will depend on wind and other conditions. Keeping this in mind, a week’s time has been kept for the launch. However, if everything goes well according to the plan, Chandrayaan-3 will be launched on July 14 at 2.35 pm.

Chandrayaan-3 spacecraft was attached to its new launch rocket LVM-3. ISRO scientists have carried out this work on June 5 at the Satish Dhawan Space Center in Sriharikota, Andhra Pradesh. Under this, Chandrayaan-3 has been linked to LVM-3 (Launch Vehicle Mark-3). The Chandrayaan-3 spacecraft completed its critical checks in March this year. In this investigation, the Chandrayaan-3 spacecraft stood up to the test of the difficult conditions faced during the launch. If this effort of ISRO is successful, it will be the only natural satellite of the Earth to reach the Moon’s orbit by covering a distance of about 3.84 lakh kilometers. After that success, India will be the fourth country in the elite club of USA, Russia and China. It is estimated that the Vikram lander of our mission will be able to land safely on the lunar surface by 23-24 August. That achievement will be historic and India will set a new dimension in the field of space science.

Chandrayaan-3 will have a propulsion module. It will carry a lander and a rover and will enable them to reach the Moon’s orbit. Under the Chandrayaan-3 mission, the equipment has been kept in two categories. According to ISRO, the scientific instruments mounted on the lander and rover were placed under the theme ‘Science of the Moon’. Along with this, experimental instruments will study the Earth from the Moon’s orbit. It will be kept under the theme ‘Science from the Moon’. The lander in the Chandrayaan-3 spacecraft is equipped with the capability to land smoothly at a specific location on the Moon. This lander will deploy the cover, which will carry out chemical analysis on the lunar surface.

Through the equipment that will be sent under this mission, thermophysical characteristics of the upper layer of lunar rocks, information about frequent earthquakes on the Moon, plasma environment on the surface of the Moon and study of the composition of the elements near the place of landing of the equipment. Will be done. The scientific instruments on the lander and rover will be able to study different aspects of the Moon, including the lunar environment and thermo-physio properties. That is, ‘Science of the Moon’ as well as ‘Science of the Moon’ is also associated with the Chandrayaan-3 mission.

One day on the Moon, the only satellite of the Earth, is equal to 29.5306 days on the Earth. Will be done during one lunar day i.e. it will take about 30 Earth days. After about 15 days it will be night and the temperature will drop to minus 170 degree centigrade or less. The situation will change in the next 15 days and after that nothing can be said about how much and what effect the cold will have on the lander. According to scientists, the initial 15 days will be very important for this mission. The purpose of this mission is to demonstrate the important technology related to landing the spacecraft on the south pole of the Moon. Under this mission, the lander has to be landed on the south pole of the Moon.

The journey that started with a bicycle and a bullock cart is today of a global scale and more than 400 companies are working in the space sector in India. India is the 5th country after USA, China, Japan, UK, where there is so much expansion of space research and business. Now America has entered into an agreement with us that its NASA will work with our ISRO on joint missions, business and research. This change and expansion is truly revolutionary in the context of India. India has faced constant neglect and criticism during its space development journey. India is a country of snakes, dung and dirty villages, we could not break this image for decades. Today, more than 140 startups in space technology are operating in India, whereas at one point there was only one startup operating in the country.

This progress has made India stand in the group of super power countries. The space economy in the world is worth Rs 30 lakh crore. India’s contribution in this is around Rs 58,000 crore. India has set a decade target that it will launch 30000 satellites. This is a huge target. What characterizes our space startups is their focus on innovation. They do not want to beat the streak of America and Europe, but their capable space engineers are constantly doing new research.

As a result, there is a competition among the world’s biggest companies as to who invests maximum in these startups. ISRO has set many records in space jump, so after 2014, 44 missions and 42 launch vehicle missions are in the name of India. However, the Chandrayaan-2 mission failed shortly before landing on the lunar surface. The moment was emotional and painful, but experiments never stop. Now if the mission of July 14 is successful, then India will be the fourth country in the world. We should wait for those moments.

In this way, many countries are involved in the lunar mission, but in this matter too, India has a direct competition with China. China has also approved the fourth phase of its moon mission and will launch Chang’e-6, Chang’e-7 and Chang’e-8 missions in future. China is also working on building a lunar research station. On the other hand, America and European countries are engaged in the mission of sending humans to the moon. Chandrayaan-3 mission is also very important for India from the point of view of the ongoing competition among all the countries of the world to reach the moon. Last time also when our mission failed, the country was plunged into deep despair and even the ISRO chief could not hold back his tears. At that time, Prime Minister Narendra Modi had assured the scientists that the cycle of success and failure goes on. Hope this time scientists will learn from the previous failure. Indians should pray to God that this time the result should not be like Chandrayaan-2, but we should get success. -freelance journalist
