BENGALURU: The landing module & # 39; Vikram & # 39; Chandrayaan-2 will begin its final descent to make a soft landing on the lunar surface on Saturday morning, while the Indian Space Research Organization (Isro) looks forward to the "terrifying" moment. "
A successful landing will make India the fourth country after Russia, the United States and China to achieve a soft landing on the Moon.
But it will be the first to launch a mission on the unexplored lunar south pole.
Along with 60 to 70 high school students from across the country, Prime Minister Narendra Modi will be present at the Isro Center in Bangalore to witness this space feat, officials said.
& # 39; Vikram & # 39; with the rover Pragyaan & # 39; Inside is scheduled for a motorized descent between 1 am and 2 am on September 7, followed by its landing between 1:30 am and 2:30 am.
The lander is now in an orbit about 35 km from the lunar surface, at its closest point to where it will begin its final descent.
ISRO announced that Chandrayaan-2 would attempt to land the landing gear and rover in a high plain between two craters, Manzinus C and Simpelius N, at a latitude of about 70 south.
ISRO President, K Sivan, said that the soft landing proposed on the Moon would be a "terrifying" moment, as ISRO had not done it yet, so that the lunar orbit insertion maneuver (LOI) had been successfully carried out during the Chandrayaan mission.
Explaining the landing maneuvers, Sivan had said that once the maneuver will begin after about 30 km to land on the surface of the moon, it will take 15 minutes.
"This 15-minute lander trip is a novelty for ISRO – it's the first time we go to another organism without the atmosphere." By using the propulsion system we will have to stop the speed and bring the vehicle safely to dry land.
To do this, we will have to find a balance between gravity and thrust. So we have to modulate the thrust of the engine, "he said.
After landing, the "Pragyaan" rover will leave "Vikram" between 5.30am and 6.30am.
While the "Pragyaan" will perform experiments on the lunar surface during a lunar period, which corresponds to 14 Earth days, the main orbiter will continue its mission for one year.
The lander and the rover carry the symbols of the country, which will stay long on the moon.
"The rover has six wheels (three on each side), the two rear wheels – one with Ashoka Chakra on it and the other with the ISRO emblem. In addition, the ramp of the undercarriage on which the rover will come out and land on the moon at Indian Flag on it, "said Sivan earlier.
The unmanned crore mission Rs 978 (satellite costs Rs 603 crores, GSLV MK III corsent Rs 375) is expected to shed light on a totally unexplored part of the Moon – its southern polar region.
Pointing out that Chandrayaan 2 was going to the South Pole, a place where no one else left, said Isro's president, K Sivan, that the entire scientific community of the nation and the world waited impatiently for the mission.
According to Isro, the lunar south pole is particularly interesting, because the lunar surface remaining in the shadow is much larger than that of the north pole and it was possible that water is present in the shaded areas permanently. .
In addition, the South Pole region had craters that are "cold traps" and contain a fossil record of the ancient solar system.
The GSLV MkIII-M1 geosynchronous satellite launcher successfully launched the 3,840-kg Chandrayaan-2 spacecraft on Earth orbit on 22 July.
The Chandrayaan-2 satellite began its journey to the moon on August 14, leaving the Earth's orbit after a crucial maneuver called Trans Lunar Insertion (TLI) performed by the ISRO to place the probe on "Transfer Path" lunar".
The spacecraft successfully entered the lunar orbit on August 20, performing a lunar orbit insertion maneuver (LOI).
On September 2, the "LG" Vikram & # 39; it's successfully separated from the orbiter. Two de-orbiting maneuvers were then performed to bring the landing gear closer to the Moon.
The spacecraft's health is subject to continuous monitoring from ISRO's mission operations complex (MOX) to the telemetry, tracking and tracking network. Command (ISTRAC) of Bengaluru, supported by the Bylalu Indian Deep Space Network (IDSN), near Bengaluru.
The orbiter carries eight scientific payloads to map the lunar surface and study the exosphere (outer atmosphere) of the moon, while the lander carries three scientific loads to conduct surface science experiments and to subsurface.
The rover carries two payloads to improve the understanding of the lunar surface.
The rover will row on the moon its own propulsion at the speed of one cm per second and will cover 500 meters during its lifetime.
According to ISRO, the goal of Chandrayaan – 2 is to develop and demonstrate the key technologies for end – to – end lunar mission capability, including soft landing and l 'airborne. wandering on the lunar surface.
On a scientific level, the mission aims to deepen the knowledge of the Moon through a detailed study of its topography, its mineralogy, the chemical composition of the surface, the thermo-physical characteristics and the atmosphere, in order to better understand understand the origin and evolution of the Moon. .
