ISRO's Chandrayaan-2 mission to carry three more payloads than Chandrayaan-1

Indian Space Research Organisation released an update ahead of its second mission to the Moon, Chandrayaan-2, due to launch in July 2019. ISRO shared the various key components in the Chandrayaan-2 mission, a sequel to the mighty-successful Chandrayaan-1, in a graphic.The Chandrayaan-2 spacecraft — which consists of an orbiter, lander and rover — will be launched on a Geosynchronous Satellite Launch Vehicle-MkIII rocket between 9-16 July 2019, ISRO Chairman K Sivan said in a statement in April.[caption id="attachment_6608761" align="alignnone" width="1024"] The complexity and challenges of Chandrayaan-2 vs Chandrayaan-1. Image credit: ISRO[/caption]ISRO has set a launch date for Chandrayaan-2 after already having seen multiple delays. Originally, the mission was meant to launch in 2013 but hit technical snags from the lander, which was being built in Russia. ISRO decided to rip up the contract in 2015 and build the lander on their own. Vikram, the new lander, gets its name from the father of ISRO and the Indian space program, Vikram Sarabhai.Vikram will be accompanied by a moon rover, Pragyan. Between them, the mission will carry a total of 13 instruments to the moon — three on the rover Pragyan and ten on the Vikram lander. The first of these instruments will go live if and when Vikram makes a soft landing on the Moon on 6 September, as planned."Once Vikram lands on the lunar surface on September 6, rover Prayan will come out of it and roll out on the lunar surface for 300 to 400 meters (984 feet to 1312 feet)," Sivan told the Times of India. "It will spend 14 Earth days on the moon carrying out different scientific experiments."[caption id="attachment_6555351" align="alignnone" width="1024"] Configuration of the Chandrayaan-2 mission rover, lander and orbiter.

However, ISRO's chief shared that the delays are only to minimise the risk of the mission by as much as possible."We saw Israel's example and we don’t want to take any risk," an ISRO official told The Hindu. "Despite Israel being such a technologically advanced country, the mission failed. We want the mission to be a success."
