Chandrayaan-2: Is it ISRO’s defeat or victory is hidden in this defeat too?

Lander ‘Vikram’ of ‘Chandrayaan-2’ lost contact with the ground station while landing on the moon. Communication was lost when the lander was just 2.1 km above the lunar surface.

If all went well, India would have become the first country in the world whose spacecraft would land close to the south pole of the lunar surface. When Chandrayaan-2 was about to land on the surface of the Moon, then contact with the lander Vikram was lost.

Before India, America, Russia, and China have done soft landings on the lunar surface, but their mission was not on the South Pole. The mission at the South Pole becomes very complicated.

When did the journey from India to the moon begin?

The journey began on October 22, 2008, when India’s space agency ISRO sent Chandrayaan-1 to the lunar orbit and claimed for the first time water ice rocks on the lunar surface.

चंद्रयान-1

Chandrayaan-1 was India’s first lunar mission. It was successfully launched on October 22, 2008, from SDSC, SHAR, Sriharikota. The spacecraft was orbiting the Moon at an altitude of about 100 km from the lunar surface for chemical, mineralogical, and photo-geological mapping of the Moon. The spacecraft carried 11 scientific instruments made in India, the United States, the United Kingdom, Germany, Sweden, and Bulgaria. After about a year, the orbiter began to suffer from several technical issues including failure of the star tracker and poor thermal shielding; On 28 August 2009, Chandrayaan-1 stopped communicating at approximately 20:00 UTC, soon after which ISRO officially declared the mission over.

History of Chandrayaan-1

→ August 15, 2003: Chandrayaan program was announced by the then Prime Minister Late Atal Bihari Vajpayee

→ October 22, 2008: Chandrayaan-1 was launched from the Satish Dhawan Space Center in Sriharikota.

→ November 8, 2008: Chandrayaan-1 entered the Moon’s transfer trajectory

→ November 14, 2008: A surface probe ejected from Chandrayaan 1 and crashed near the Moon’s south pole, probe confirms the presence of water molecules on the lunar surface

→ August 28, 2009: The termination of the Chandrayaan-1 program was announced

What is Chandrayaan-2 and what is its purpose?

‘चंद्रयान-2’

Why was the south pole of the moon chosen for this?

The Moon’s south pole is particularly interesting because a larger portion of its surface remains in a shadow than the north pole. Around it, there is likely to be water in these permanently shadowed areas. The cold craters of the Moon’s south polar region contain the lost fossil record of the early Solar System. Chandrayaan-2 carrying the Vikram lander and the Pragyan rover was about to make a soft landing in the plain between two craters – Manzinus C and Simpelius N, at about 70° south latitude, but it was hard hit due to loss of communication with the mission control center. The lander Vikram is still intact on the surface of the Moon, but contact has not been made yet.

Launch of Chandrayaan-2, equipment, and launch vehicle in it:

India’s Geosynchronous Satellite Launch Vehicle (GSLV) Mark III-M.1 passed the spacecraft Chandrayaan-2 at a distance of 169.7 km on 22 July 2019. perigee (closest point to Earth) and 45,475 km. Successfully launched into the planned orbit with an apogee (farthest point from Earth) of. The launch was done from the second launch pad of Satish Dhawan Space Centre-SHAR, Sriharikota.

The Chandrayaan-2 mission is a highly complex mission, which represents a significant technological advancement over ISRO’s previous missions. It consists of an orbiter, lander and rover to explore the untouched South Pole of the Moon. The mission has been designed to learn more about the Moon by studying the lunar topography, seismology, mineral identification and distribution, chemical composition of the surface, thermo-physical characteristics of the upper soil, and the composition of the thin lunar atmosphere. So that scientific knowledge can be increased and new information can be obtained about the origin and development of the Moon.

After the injection of Chandrayaan-2, several maneuvers were carried out to raise its orbit and after the Trans Lunar Insertion (TL1) maneuver on 14 August 2019, the spacecraft came out of the Earth’s orbit and proceeded to approach the Moon. Went towards the path. Chandrayaan-2 was successfully injected into the lunar orbit on 20 August 2019. 100 km While orbiting the Moon in a lunar polar orbit, the Vikram lander separated from the orbiter in preparation for landing on 02 September 2019.  After that, its orbit changed to 100×35 km of the Moon. Two orbit-changing maneuvers were carried out to start the orbit. The landing of Vikram Lander was as per plan and 2.1 km. Its performance was observed to be normal up to the height of. After this, the lander lost contact with the ground stations.

Prime Minister Shri Narendra Damodar Das Modi hugged ISRO Chief Dr. K. Sivan, looking emotional about the mission is incomplete.

This mission was so important or u say that there is still hope that it can be successful. The eyes of the whole world were moist when they remained incomplete. However, later ISRO found the lander which is still on the moon. Scientists hope that they will re-communicate with him.

The whole of India was awake to see this mission. Even the whole world was awake the whole night to see its success. During this entire mission, it was as if the whole of India had reached ISRO. Many writers have written stories and poets on this, I have also written a story for my college magazine.

Why are we saying that a big victory of India is also hidden in the incomplete journey of the moon?

The lunar orbiting orbiter is advancing our understanding of the Moon’s evolution by mapping the mineralogy and hydrologic composition of the lunar polar region using its eight state-of-the-art scientific instruments. The orbiter’s camera (0.3 m) has a higher resolution than any camera used in previous lunar missions, which will be of great use to the global scientific community. As a result of launch and mission management, a total mission period of seven years has been ensured, due to which now we will be able to observe the moon for 7 years instead of the planned one year.

Vikram Lander may have been disappointed, but this mission has not failed. Because Chandrayaan-2’s orbiter is doing its work in the moon’s orbit. This orbiter has many scientific instruments and is working well. Vikram Lander and Pragyan Rover was an experiment. It was designed for just 17 days. This prototype made way for “Chandrayaan-3” easy, and it will help in future missions to a great extent.

India can launch Chandrayaan-3 in the first half of 2021.

Earlier, on 7 September 2019, the Vikram lander, which was trying to land on the south pole of the Moon as part of the Chandrayaan-2 mission, crashed. Since then, India is preparing for its Chandrayaan-3 mission. Chandrayaan-3 may be launched in 2025, its cost will be less than the previous mission. Work is going on on this and this time we will definitely run our rover on the moon.
