India launched its most ambitiousspace mission. With the help of the GSLV MK-III launch vehicle weighing 640 tons, the interplanetary space station Chandrayaan-2 set off to the moon. This launch was to take place on July 15, but due to unnamed technical problems, it was decided to postpone it 56 minutes before the start. The success of this mission will depend on whether India will become the fourth country after the USSR, the USA and China, which will be able to gently land the spacecraft on the Earth satellite.
The mission Chandrayaan-2 continues the Indian lunarprogram launched in October 2008 by the Chandrayan-1 unit. He worked in a circumlunar orbit for 312 days and sent a shock probe to the surface of the satellite, which made a hard landing near the Shackleton crater, located near the south pole of the moon.

The launch of Chandrayaan-2 coincided with the 50th anniversary of the landing.US astronauts to the surface of the moon July 20, 1969. As indicated on Twitter’s Twitter by the Indian Space Research Organization (ISRO), 7500 people followed the start of such an ambitious mission for the country a few kilometers from the launch site.

Chandrayaan-2 to overcome 384thousands of kilometers and more than five weeks to reach the moon. But flying to the moon is not the only task of the mission. The fact is that the Indian interplanetary station consists of three parts: the orbital station itself weighing 2379 kg, the Vikram descent module weighing 1471 kg, and the 27-kilogram six-wheeled automated Pragyaan lunar rover. Naval stereo camera and devices for searching light and heavy chemical elements in the surface layer of the lunar regolith are installed on the moon rover.
Landing module Vikram and lunar rover Pragyaan
The descent module and the lunar rover are planned to land.where no one else has been - at the South Pole of the Moon. According to the calculations of the Indian Space Research Organization, landing will occur on September 6 or 7. This will be the most difficult stage of the mission. Recall that in April, with a similar operation, Israel’s first lunar unit crashed.
Tasks of the Chandrayaan-2 mission
According to Indian scientists, the southern circumpolarthe regions of the moon are of particular interest, since, compared with the North Pole, most of their surface is in the shade. According to the Indian Space Research Organization, the Chandrayan-2 missions have several tasks to accomplish.
Pragyaan lunar rover
Landing module and robotic lunar rover,powered by solar panels (power 50W), they will search for water and minerals, as well as explore seismic activity on the satellite. The ISRO expects that the lunar rover will be able to work on the surface for 14 days. During this time, he will overcome up to 500 meters of the Moon’s surface (the car’s speed is 1 cm per second), take a photo shoot and send all the scientific data and images received to the landing gear. That, in turn, will be able to transfer all the collected information to Earth. The estimated time of the orbiter is 1 year.

The Chandrayaan-2 mission is estimated at almost $ 150 million.
