Chandrayaan 2 leaves Earth orbit towards the Moon



New Delhi:

India's ambitious mission to the moon Chandrayaan 2 left Earth orbit today and heads for the Moon after a decisive maneuver by the Indian Space Research Organization.

The satellite is one step closer to the moon after that The Trans Lunar Insertion (TLI) maneuver was successfully completed at 2:21 am as planned, "said the space agency.

"The final Chandrayaan 2 spacecraft lift maneuver was successfully completed today at 02:21 am IST During this maneuver, the spacecraft's liquid engine was fired for approximately 1203 seconds, thereby entering Chandrayaan-2's lunar module "ISRO said in a statement. An orbital lifting maneuver is the process of orbiting a satellite into orbit toward the moon while it still revolves around the earth.

An avid ISRO chief, dr. K Sivan said to NDTV: "The shooting had to be precise and absolutely accurate, as now from a distance of 276 kilometers from Earth – where the midnight operation was carried out at Chandrayaan 2 – it will now be a long moon marathon of 3.84 lakh km to the moon. "

" The whole process is very complex as Chandrayaan 2 was given a 39,240-kilometer descent per hour, which is almost 30x the speed at which sound travels through the air, "said he. Even a small mistake can cause Chandrayaan 2 to miss his rendezvous with the moon, he added.

Chandrayaan 2, considered to be the most complex and prestigious mission of ISRO, will make India the fourth country to softly land a rover on the lunar surface after Russia, USA and China. The last nation that attempted a gentle landing on the moon, Israel, failed at their first attempt earlier this year.

The mission is characterized by low costs with a few Rs. 1,000 crores were spent on mission preparation – a much lower price than similar missions in other countries.

The orbit of the spaceship "gradually quintupled" between July 23 and August 6, after India's second lunar mission was launched on July 22 from the launch pad at Andhra Pradesh Sriharikota on July 22.

The take off was successful on the second attempt, a week after it was canceled just under an hour after launch due to a technical breakdown. The 3.8-tonne satellite will now cruise for the next six days and is expected to reach orbit around the moon on August 20th.

When the spacecraft approaches the moon on August 20, its liquid engine will be fired again to launch into the lunar orbit, ISRO said. "Then four orbit maneuvers are performed to bring the spacecraft into its final orbit, which runs over the lunar poles at a distance of about 100 km from the lunar surface," it says.

After 13 days of moon-bound orbit In orbit, the spacecraft will attack Vikram, a 1.4-ton lander that will drop the 27-kilogram Pragyan on a plateau between two craters at the Moon South Pole, where, according to sources no country has landed so far is the ISRO. It is expected to land softly on the moon on September 7th.

After landing, the rover carries out one lunchtime experiments on the lunar surface, which corresponds to 14 earth days. The lander's missionary life is also a lunar day, while the orbiter will continue his mission for a year.

The Chandrayaan 2 mission aims to expand the knowledge of the Moon, leading to a better understanding of its origins and evolution.
