Sriharikotta:21/7/19:The twenty-hour countdown for India’s second lunar mission Chandrayaan-2 began this evening at the national spaceport at Sriharikotta. The Indian Space Research Organization ISRO said, the countdown started at 6.43 pm and is progressing smoothly. The country’s most powerful booster, GSLV-Mark-Three, will take off at 2.43 hrs in the afternoon tomorrow, carrying the high-stake Chandrayaan-2 probe from the second launch pad of the space station. The launch rehearsal made by the ISRO today has found that all mission parameters are normal.
ISRO Chairman Dr K Sivan told reporters at Chennai Airport this morning that the technical snag that occurred in the rocket GSLV-Mark-Three on July 15 has been fully rectified. He said all preparations have been made for the launch tomorrow. He informed that fifteen crucial manoeuvres would be made after the launch for navigating Chandrayaan-2 to reach the moon.
The 43.43 meters long, 640-ton rocket GSLV-Mark-Three will take Chandrayaan-2 to a highly elliptical orbit around the earth. From there, it will be taken to the South Pole of the moon by 7th September, by carrying out multiple firing of the engine onboard Chandrayaan-2, as said by ISRO.
The 978 crore rupees worth mission would propel India as the fourth country ever in the elite club of nations having their own probes soft landing on the moon.
Chandrayaan-2 weighing 3.85 ton consisting of the orbiter, the lander and the rover have a total of 13 payloads to study the moon and a facility for passive experiment. The orbiter and the lander are capable of sending data to the ISRO’s Deep Space Network at Byalalu near Bengaluru. The lander is to descend on a high plain between two craters in the moon’s South Pole. Space scientists view the moon as a test-bed for deep space ventures. The present moon expedition is one of the most complex space missions ever made by the nation. The snags found in the cryogenic upper stage of the rocket just before an hour of the previously scheduled launch on the 15th of this month have been plugged, boosting the confidence of the scientists to have the mission during the prevailing launch window itself. Apart from the potential to unveil the secrets of the moon, the mission is all set to rekindle scientific temper among the youth of the nation.
