heart beating will be fast during 15 Minutes Await Chandrayaan-2 as India's Ambitious Moon Mission will Create History Tonight
Bangalore: The Chandrayaan-2 'Vikram' landing module will begin its final descent to make a historic smooth landing on the lunar surface in the early hours of Saturday, while the Space Research Organization of India 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 he will be the first to launch a mission to the unexplored lunar south pole.
Together with about 60-70 high school students from across the country, Prime Minister Narendra Modi will be present at the ISRO center in Bangalore to witness the space feat, according to officials.
'Vikram' with the rover 'Pragyaan' housed inside is scheduled for a motorized descent between 1 a.m. and 2 a.m. on September 7, followed by its landing between 1.30 a.m. The landing module is now in an orbit that would be about 35 km from the lunar surface at its closest point from where its final descent will begin.
ISRO has said that Chandrayaan-2 will attempt to gently land the landing module and rover on a high plain between two craters, Manzinus C and Simpelius N, at a latitude of approximately 70 south. The president of ISRO, K Sivan, said that the proposed soft landing on the Moon was going to be a "scary" moment, since ISRO had not done it before, where the lunar orbit (LOI) insertion maneuver was taken to carried out successfully during the Chandrayaan-1 mission.
In explaining the landing maneuvers, Sivan had said that once the maneuver starts from about 30 km to land on the surface of the moon, it will take 15 minutes. "This 15-minute trip of the landing module is new to ISRO. It is the first time we go to another body where there is no atmosphere and, using the propulsion system, we will have to break the speed and safely carry the vehicle to the ground soft".
To achieve this, we will have to balance gravity and thrust. So we have to modulate the engine thrust, "he said. After landing, the rover 'Pragyaan' will leave 'Vikram' between 5.30 and 6.30.
While the 'Pragyaan' will conduct experiments on the lunar surface for a period of one lunar day, which is equal to 14 Earth days, the main orbiter will continue his mission for a year. The landing module and the rover carry symbols of the country, which will remain on the moon for a long time.
"The rover has six wheels (three on each side), the two rear wheels, one has Ashoka Chakra and the other has the ISRO emblem. In addition, the landing module ramp on which the rover will leave and land on the moon has Indian flag, "Sivan had said previously.
The unmanned lunar mission Rs 978 crore (satellite costs Rs 603 crore, GSLV MK III costs Rs 375 crore) is expected to shed light on a completely unexplored section of the Moon: its southern polar region.
Noting that Chandrayaan 2 was heading to the South Pole, a place where no one else had gone, ISRO president K Sivan had said that the entire scientific community of the nation and the world were anxiously awaiting the mission.
According to ISRO, the lunar South Pole is especially interesting because the lunar surface here that remains in the shade is much larger than that of the North Pole and there is a possibility of the presence of water in permanently shaded areas around it.
In addition, the South Pole region had craters that are "cold traps" and contain an early Solar System fossil record. India's geosynchronous satellite launch vehicle, GSLV MkIII-M1, had successfully launched the 3,840 kg Chandrayaan-2 spacecraft into Earth's orbit on July 22.
The Chandrayaan-2 satellite began its journey to the moon leaving Earth's orbit in the dark hours on August 14, after a crucial maneuver called Trans Lunar Insertion (TLI) that ISRO carried out to place the spacecraft in the "Lunar transfer path".
The spacecraft successfully entered the lunar orbit on August 20 when performing the lunar orbit insertion (LOI) maneuver. On September 2, the 'Vikram' landing module was successfully separated from the orbiter, after which two exorbitant maneuvers were carried out to bring the landing module closer to the Moon.
The spacecraft's health is being continuously monitored from the Mission Operations Complex (MOX) in the ISRO Telemetry, Tracking and Command Network (ISTRAC) in Bengaluru with the support of the Indian Deep Space Network (IDSN) antennas ) in Bylalu, near Bengaluru.
The orbiter carries eight scientific charges to map the lunar surface and study the exosphere (outer atmosphere) of the Moon, while the landing module carries three scientific charges to conduct surface and subsup scientific experiments
