Bengaluru: “Our heart was almost stopping”, was how ISRO Chairman K Sivan described the tense moment when team Chadrayaan-2 attempted to inject the spacecraft into the lunar orbit on Tuesday.As ISRO scientists started firing Chandrayaan-2’s onboard liquid engine to put the spacecraft in an orbit around the Moon, Sivan said “our heartbeat increased”. “For 30 minutes, our heart was almost stopping,” he told a press conference after the Lunar Orbit Insertion (LOI) maneuver was completed successfully at 0902 hours as planned, using the onboard propulsion system.

However, ISRO was confident about the soft-landing. “We have done enough tests, simulations…sub-systems, systems…sensor level…whatever humanly possible, we did,” he added.

Chandryaan-2 comprises an Orbiter, Lander (Vikram) and Rover (Pragyaan). The mission life of Orbiter would be one year, whereas that of lander (Vikram) and rover (Pragyan) would be one Lunar day, which is equal to 14 earth days. According to ISRO, Chandrayaan 2 — India’s second lunar expedition — would shed light on a completely unexplored section of the Moon, its South Polar region. “This mission will help us gain a better understanding of the origin and evolution of the Moon by conducting detailed topographical studies, comprehensive mineralogical analyses, and a host of other experiments on the lunar surface”, the space agency had said. “While there, we will also explore discoveries made by Chandrayaan 1, such as the presence of water molecules on the Moon and new rock types with unique chemical composition”, it was stated.
