INDIA AIMS TO BE 1ST COUNTRY TO LAND ROVER ON MOON'S SOUTH POLE India will become the first country to land a rover on the Moon's the south pole if the country's space agency "Indian Space Research Organisation (ISRO)" successfully achieves the feat during the country's second Moon mission "Chandrayaan-2" later this year. "This is a place where nobody has gone. All the ISRO missions till now to the Moon have landed near the Moon's equator. Chandrayaan-2, India’s second lunar mission, has three modules namely Orbiter, Lander (Vikram) & Rover (Pragyan). The Orbiter and Lander modules will be interfaced mechanically and stacked together as an integrated module and accommodated inside the GSLV MK-III launch vehicle. The Rover is housed inside the Lander. After launch into earth bound orbit by GSLV MK-III, the integrated module will reach Moon orbit using Orbiter propulsion module. Subsequently, Lander will separate from the Orbiter and soft land at the predetermined site close to lunar South Pole.

  • GSLV Mkiii-M1 Chandrayaan 2
    INTRODUCTION Chandrayaan 2 is an Indian lunar mission that will boldly go where no country has ever gone before — the Moon’s south polar region. We aim to improve our understanding of the Moon, which could lead to discoveries that will benefit India and humanity as a whole. These insights and experiences will cause a paradigm shift in how lunar expeditions are approached for years to come, propelling further voyages into the farthest frontiers. WHY ARE WE GOING TO THE MOON? The Moon is the closest cosmic body on which space discovery can be attempted and documented. It is also a promising test bed to demonstrate technologies required for deep-space missions. Chandrayaan 2 attempts to foster a new age of discovery, increase our understanding of space, stimulate the advancement of technology, promote global alliances, and inspire a future generation of explorers and scientists.

Murty1, and Anil Bhardwaj1 1Physical Research Laboratory, Ahmedabad 2Space Application Centre, Ahmedabad 3U. R. Rao Satellite Centre, Bengaluru Email: [email protected] Abstract Alpha Particle X-ray Spectrometer (APXS) is one of the two scientific experiments on Chandrayaan-2 rover named as Pragyan. The primary scientific objective of APXS is to determine the elemental composition of the lunar surface in the surrounding regions of the landing site. This will be achieved by employing the technique of X-ray fluorescence spectroscopy using in-situ excitation source 244Cm emitting both X-rays and alpha particles. These radiations excite characteristic X-rays of the elements by the processes of particle induced X-ray emission (PIXE) and X-ray fluorescence (XRF). The characteristic X-rays are detected by the ‘state-of-the-art’ X-ray detector known as Silicon Drift Detector (SDD), which provides high energy resolution as well as high efficiency in the energy range of 1 to 25 keV. This enables APXS to detect all major rock forming elements such as, Na, Mg, Al, Si, Ca, Ti and Fe. The Flight Model (FM) of the APXS payload has been completed and tested for various instrument parameters.

The Sentinelese, a negrito tribe that lives on the North Sentinel Island of the Andamans, remains hostile to outsiders. Based on carbon dating by the Anthropological Survey of India, Sentinelese presence was confirmed in the islands to 2,000 years ago. The Govt. of India issued the Andaman and Nicobar Islands (Protection of Aboriginal Tribes) Regulation, 1956 to declare the traditional areas occupied by the tribes as reserves, and prohibited entry of all persons except those with authorisation. Photographing or filming the tribe members is also an offence. The rules were amended later to enhance penalties. But restricted area permits were relaxed for some islands . Almost nine months after American national John Allen Chau was recently. allegedly killed by the Sentinelese on the North Sentinel Island of Andaman and Nicobar islands, a recent publication by the Anthropological Survey of India (AnSI) throws more light on the incident and also the ways of one of the most isolated tribes in the world. Titled The Sentinelese of the North Sentinel Island: A reprisal of Tribal Scenario in an Andaman Island in context of Killing of an American Preacher. “On November 14, Chau left Port Blair and reached the island at night. He spent the entire day of November 15 with the Sentinelese and on the night when he met the fishermen who had transported him to the island, he gave them the dairy in which he had recorded his experience of the day,” the director said. The orbiter is safe in the intended orbit around the moon.

  • Chandrayaan-2 India's Daring Moon Mission
    COVER STORY Chandrayaan-2 India’s Daring Moon Mission Biman Basu 14 | Science Reporter | November 2019 Fifteen Minutes of Terror This was, however, not entirely unexpected. Chandrayaan-2 was an extremely complex mission the like of which ISRO had never tried before. The critical manoeuvre of soft landing lasting 15 minutes was what the ISRO Chairman K. Sivan had described as “Fifteen minutes of terror”. It was to be an ‘autonomous powered descent’ to the lunar surface and was the most difficult part of the whole mission. Since it involved intricate and rapid changes in the velocity and flight path of the lander, the entire manoeuvre was controlled by the spacecraft’s onboard computer, without any guidance from the ground. The time-lag to execute Artist’s impression of Chandrayaan-2 in commands from the Earth to the Moon Moon orbit ruled out ISRO’s mission control centre in Bengaluru controlling the lander’s descent.
