Description about eBook : From The Editor-in-Chief

Space is hard,” NASA tweeted hours after its Indian counterpart ISRO’s Chandrayaan 2 mission ended in disappointment and it lost radio contact with the Vikram lander. The spacecraft is now believed to have suffered a hard landing on the Moon. NASA’s words of encouragement commending ISRO’s attempt are significant. No other agency knows how hard space is—multiple tragedies have not deterred the US space agency from its motto of exploring space ‘for the benefit of all’. It is also an acknowledgement of ISRO’s commendable efforts to catch up with the US, Russia and China, the big boys of the space club. Over the past decade, ISRO has sent probes to Mars and perfected the GSLV Mark III launch vehicle that can carry a four-tonne satellite into the Earth’s orbit. Indeed, rarely has science captured the popular imagination in India as it did in the early hours of September 7 as millions of Indians tuned in to watch the final leg of Chandrayaan 2’s journey to the moon. India’s space programme has been a source of national pride, and justifiably so. Chandrayaan 2 attempted to make India the first country to land a mission on the moon’s remote, unexplored South Pole and unlock its secrets. It had to contend with the fact that lunar soft landings have to deal with very high failure rates, the reason only three countries—the US, the erstwhile USSR and China—have achieved them. ISRO has mastered several critical technologies in this mission, including detaching the orbiter and lander and firing the four rockets in the descent phase. It experienced failure only on the final lap and, even here, the failure of the Vikram lander and the Pragyaan rover must not obscure the fact that they comprised only 30 per cent of the mission. Chandrayaan 2 remains in lunar orbit. Its eight instruments are still ticking and sending valuable data about the surface of the moon back to ISRO’s earth stations...............
