In an attempt to become the fourth nation after the USA, USSR and China India launched a space mission Chandrayaan 2 on 22 July 2019 from Satish Dhawan Space center for a safe landing on Lunar surface.
According to ISRO, Lunar landing of Vikram Lander, named after the father on India’s Space program was normal and according to the plan until it reached 2 kilometers of Lunar surface. It was the time when the ground station lost contact with lander minutes before the time for landing on the surface of the moon on 6th September 2019. The Chandrayaan 2 lander has been spotted by the orbiter on 8th September 2019. However, a connection has not been maintained between orbiter and lander until this moment.
Lander of Chandaryaan-2:
ISRO will continue to strive to establish a connection with a lander. According to ISRO’s estimate, the lander will get sunlight for one lunar day that is equal to 14 days of the earth so ISRO is left with 10 more days for putting their all efforts to save their mission. Lander has a life of only 14 days for this mission. Though lander also has internal batteries and a solar panel that can generate power as mentioned before lander didn’t have a soft landing which might have destroyed its some parts.
Lander Vikram has landed closed to the site in the unexplored south pole but it had a hard landing though it is in one piece not broken. It is in tilted position on the surface of the moon. Lander has a mass of 1471 kg.
Rover of Chandaryaan-2:
Along with lander, there is rover named as Pragyan. It is a 6 wheels vehicle with a mass of 27 kg. This rover is designed to have direct communication with the lander. The purpose of this rover was to collect chemical and mineral samples from the lunar surface. ISRO has not yet provided any update about the rover and its mission.
Orbiter of Objective of Chandaryaan-2:
Meanwhile, Orbiter of Chandrayaan-2 that is a boxed shaped craft with an orbital mass of 2379 kg and a solar array capable of generating 650 W of solar power. This orbiter is in perfect condition and it will continue to orbit around the moon for 100 km above Moon’s surface. The orbiter will conduct remote sensing observations. It will study the Moon for 7 years.
All the technology worked perfectly before the landing of the lander on the moon. According to ISRO’s official 90 to 95% of the objectives of this mission are achieved. Another official of ISRO declared that there are good chances of restoring the connection of lander with the ground station.
The objective of lander of Chandaryaan 2:
The main objective of chandaryaan-2 lander was to operate the robotic lunar on the surface of the Moon. Scientific goals include orbital studies of lunar topography, mineralogy, elemental abundance, the lunar exosphere, and signatures of hydroxyl and water ice.
The budget of Chandaryaan-2:
ISRO has a unique quality of making space missions possible at very low cost as compared to NASA. The budget of Chandarayaan-2 mission is about $140 million that is one-twentieth of NASA’s mission. Its total cost is even less than Marvel’s movie “Endgame”.
Indian Prime Minister Narendra Modi boosted the morale of his nation and ISRO scientist with the following words. “Sisters and brothers of India, resilience, and tenacity are central to India’s ethos. In our glorious history of thousands of years, we have faced moments that may have slowed us. But they have never crushed our spirit,” he said.
“We have bounced back again … This is the reason our civilization stands tall,” he said in Bangalore. “When it comes to our space program, the best is yet to come.”
The whole world has its eyes on the lander named Vikram. if this mission becomes successful India will become one of the elite nations of the world. This landing is a great achievement for the whole world of technology.
