The landing module & # 39; Vikram & # 39; Chandrayaan-2 was brought closer to the Moon on Wednesday after its orbit was lowered further from where it will begin its final descent to achieve a soft landing on the lunar surface early Saturday.
Prime Minister Narendra Modi will be attending the ISRO Bangalore Center to attend this space event, alongside 60 high school students from across the country, said a senior official from the Indian Space Research Organization (ISRO).
A successful landing taking away billions of dreams on the moon will make India the fourth country after Russia, the United States and China to achieve a soft landing on the lunar surface. But it will be the first to launch a mission to the South Pole of the Moon, still unexplored.
The nine-second deorbiting maneuver – the second in two days – was carried out at 3:42 am using the Lander's on-board propulsion system, said ISRO in a statement updating the latest update from the unmanned lunar mission.
"Thanks to this maneuver, the orbit required for the Vikram Lander to begin its descent to the Moon's surface is realized," the text adds.
The Lander is now in an orbit that would be about 35 km from the lunar surface at its nearest (perigee) point from where it will begin its final descent onto the moon, adding that the orbit was at 101 km from the lunar surface. to the farthest (climax). The Chandrayaan-2 spacecraft continued to orbit the moon at a 96-kilometer perigee and a 125-kilometer climax.
"The Orbiter and the Lander are in good health," said ISRO.
He added that the Lander should conduct a motorized descent on September 7 between 1 am and 2 am, followed by a landing between 1:30 and 2:30 am.
After landing, the "Pragyan" rover will leave "Vikram" from 5.30am to 6.30am and conduct lunar surface experiments for a period of one lunar day, ie 14 Earth days. The main orbiter will continue its mission for one year.
"Chandrayaan 2 is ready to take a billion dreams on the moon now stronger than ever before," said ISRO in announcing the postponed date for the launch after takeoff on July 15, due to the fact that it is "a good thing. a technical problem.
A week later, the GSLV MkIII-M1 geosynchronous satellite launch launcher managed to place the 3,840 kg Chandrayaan-2 spacecraft on the Earth's orbit on July 22nd.
ISRO President, K Sivan, said that the soft landing proposed on the Moon would be a "terrifying" moment, as ISRO has not yet done so, while the Lunar Orbit Insertion (LOI) maneuver was successfully completed during the Chandrayaan-1 mission.
Describing a soft landing on the moon, G Madhavan Nair, former leader of ISRO, said that it was a kind of flying saucer floating at the top, then slowly descending as in science fiction.
It's almost a similar sequence that ISRO will implement, with virtually no real-time control in the field.
"… Only on-board cameras would look for the right location, and once the match is achieved, five rocket engines control precisely by first reducing speed and then virtually floating it there, then performing a slight lateral movement in an interview with PTI, explains Nair in an interview with PTI.
Cameras, laser telemetry systems, on-board computers and, most importantly, the software needed for the entire operation must work in unison, said Nair, who had led the mission Chandrayaan-1 more than ten years ago.
"It's a very, very complex operation. I do not think a country has done a similar operation trying to get real-time images, and then trying to have an on-board computer implement the landing function autonomously.
"It will be a remarkable event and we are all looking forward to seeing it and I am sure it will be a 100% success," he said.
To raise awareness of its space programs, ISRO had organized an online quiz for students in class 8 to class 10 in August. The space agency selected the top 60 students to attend this historic event .
"Two students (from Class 8 to Class 10 only) with the highest scores will be invited to ISRO, Bengaluru Center, to attend the Chandrayaan-2 lunar landing on the Moon, along with the other." Honorable Prime Minister Narendra Modi, "under the terms and conditions of the quiz on the MyGov.in, an innovative platform to build a partnership between citizens and government with the help of technology for growth and development from India.
Chandrayaan-2 began its journey to the moon on August 14, leaving Earth's orbit after a crucial maneuver called Trans Lunar Insertion (TLI) performed by the ISRO to place the probe on "Lunar Transference Trajectory" .
The Chandrayaan-2, which crossed the moon's cape on August 20, took a decisive step in carrying out the second Indian lunar mission by performing the LOI maneuver.
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 expedition would also highlight part of the totally unexplored moon, its southern polar region.
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.
