India to land on the moon in a few hours
New Delhi [India] : India is all set to script history with the landing of its ambitious moon mission Chandrayaan-2 on the south pole of the lunar surface at 1:55 am on Saturday.
It's rover Pragyan, which translates to 'wisdom' in Sanskrit, will roll out of the lander -- Vikram -- between 5:30 am to 6:30 am to carry out experiments on the surface.
Pragyan weights 27 kilograms, has 6-wheels and can travel up to 500 m (0.5 km) at a speed of 1 cm per second, and leverages solar energy for its functioning.
Once at the lunar surface, Vikram and Pragyan will be functioning for one lunar day or 14 earth days while the mission life of Chandrayaan-2's orbiter will be one year.
The mission's payloads consist of Terrain Mapping Camera-2, Large Area Soft X-ray Spectrometer, Solar X-Ray Monitor, Imaging IR Spectrometer among others.
The objective of Chandrayaan-2, which was launched on July 22, to expand the lunar scientific knowledge through a detailed study of topography, mineralogy, surface chemical composition, thermo-physical characteristics and tenuous lunar atmosphere leading to a better understanding of the origin and evolution of the moon. It also aims at developing and demonstrating key technologies for end-to-end lunar mission capability, including soft-landing and roving on the lunar surface.
Prime Minister Narendra Modi will be at the ISRO headquarters in Bengaluru around midnight to watch the final descend of Chandrayaan-2.
Over 60 high school students across the country who cleared an online space quiz last month will watch the historic event with Modi.
India's fully-indigenous and second mission to the moon was approved by the cabinet in September 2008, just before the launch of Chandrayaan 1.
While taking immense pride over India's Chandrayaan-2 mission, citizens across the nation are eagerly waiting for its historic landing on the surface of the moon.
While talking to ANI, a lot of people expressed their delight and wished a safe landing as India's ambitious lunar mission begins its descent on the moon.
Here is timeline of the historic mission.
September 18, 2008 The then Prime Minister Manmohan Singh's Cabinet approved the Chandrayaan-2 lunar mission. The subsequent years went into mission planning and execution with home-grown technology used for the expedition.
July 15, 2019 The launch of Chandrayaan 2 was called off about an hour before the launch due to technical snag.
July 22, 2019 ISRO successfully launched Chandrayaan-2 from Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh.
July 24, 2019 First earthbound orbit-raising manoeuvre for Chandryaan-2 spacecraft performed successfully.
July 26,2019 Second earthbound orbit-raising manoeuvre for Chandryaan-2 spacecraft performed.
July 28,2019 Third orbit-raising manoeuvre performed.
August 3, 2019 ISRO released the first set of earth pictures captured by Chandrayaan 2
August 6, 2019 Fifth and the last orbit-raising manoeuvre performed
August 14, 2019 After revolving around the earth's orbit for nearly 23 days, the spacecraft entered the Lunar Transfer Trajectory.
August 20, 2019 Chandrayaan-2 successfully inserted into lunar orbit. August 22,2019 ISRO released first moon image captured by Chandrayaan-2's LI4 Camera.
September 1, 2019 The fifth and lunar manoeuvre executed successfully.
September 3, 2019 The first de-orbiting manoeuvre performed successfully in four seconds.
September 4, 2019 The second de-orbiting manoeuvre executed in nine seconds.
September 7, 2019 The Vikram lander of Chandrayaan 2 scheduled to soft-land on moon between 1.30 am and 2.30 am on Saturday. It will be followed by the rollout of rover 'Pragyan' between 5.30 a.m and 6.30 a.m.
"It's the biggest step towards becoming a developed nation, such initiatives will make way for our country to have a say in the world. We at 'Vani'- the debating society of Lady Irwin college have organised a debate program and the topic of which is selected keeping in mind the Chandryaan-2," said another student Mehar.
Nancy Goyal, who seemed to be much excited about the landing said that science subject always interests her, so she would be watching the live telecast of Chandrayaan-2 landing on her "TV set”.
"For the first time, our country is gaining much popularity in the whole world for a space-related event. It makes me feel proud and such initiatives would motivate Indian scientists who are working outside the country to stay and work for our nation" said Anjali, another student.
School students from Chennai have expressed delight and excitement as only a few hours are left for Chandrayaan-2's soft-landing on the lunar surface.
Mrinalini, who seemed over-enthusiastic about this mission said, "At this moment, I feel really proud to speak about India's greatest mission Chandrayaan 2. K Sivan who comes from a poor background like that of APJ Abdul Kalam has become my inspiration, and under his guidance, we are going to land on the surface of the moon, I am really very excited about it."
Sabarish, who had depth knowledge about Chandrayaan-2 said that the last 15 minutes of the landing is going to be so crucial, if the moon had an atmosphere, it would have been much easier, we would have deployed a parachute and slowly reduced the speed and landed on the moon, but now in this case of no atmosphere, speed has to be reduced very accurately.
