The Indian Space and Research Organisation (ISRO) has postponed launch of India’s second lunar mission ‘Chandrayaan-2’ from April 2018 to October-November 2018 as experts have suggested more tests. It will be launched on board of Geosynchronous Satellite Launch Vehicle Mk III (GSLV-F10).
Chandrayaan 2 is India’s second mission to Moon and is advanced version of previous Chandrayaan-1 mission (launched in 2008). It has been developed indigenously by ISRO. It consists of Orbiter, Lander and Rover configuration. In this mission, ISRO will for first time attempt to land a rover on moon’s south pole.
The spacecraft (orbiter) weighs around 3,290 kg and it will orbit around moon and perform objectives of remote sensing moon. Once GSLV-F10 putspacecraft in 170 km x 20,000 km elliptical orbit, orbiter will be manoeuvred towards 100-km lunar orbit by firing thrusters and then lander housing the rover will separate from orbiter.
The six wheeled rover will move on lunar surface and collect soil or rock samples for on-site chemical analysis to gather scientific information on lunar topography, mineralogy, elemental abundance, lunar exosphere and signatures of hydroxyl and water-ice. The data will be relayed to Earth through orbiter. The rover will move around landing site in semi-autonomous mode as decided by the ground commands.
Note: The soft-landing on the lunar surface of the moon will be most complex part of Chandrayaan 2 mission. Only the US, Russia and China have been able to soft-land spacecraft on lunar surface.
The NITI Aayog has launched first course on Sustainable Urban planning using remote sensing and Geographic Information System (GIS) at IIT Kanpur’s outreach centre in Noida.
This is first course conducted under Global Initiative on Academic Network (GIAN) Program of Union Ministry of Human Resource Development. It is actively supported by NITI Aayog and Ministry of Housing and Urban Affairs.
The course aims to give participants state-of-the-art remote sensing and GIS skills to allow them managing rapidly changing urban environment of Indian cities. Its prime focus is on issues such as water resource management, water pollution and water treatment facilities.
It is expected to contribute significantly to build trained manpower for Smart Cities that aims to promote sustainable and inclusive cities that provide core infrastructure and give decent quality of life to its citizens through clean and sustainable environment and application of Smart Solutions.
The participants for this course are mainly from Government departments such as ISRO, National Mission on Clean Ganga, AP Remote Sensing Application Centre and students from different engineering colleges and universities across country.
Global Initiative on Academic Network (GIAN)
GIAN in Higher Education is scheme of HRD Ministry that aims to boost the quality of the country’s higher education through international collaboration. Its objective is to increase footfalls of reputed international faculty to Indian academic institutes and thereby bring in international academic excellence in India’s higher education institutions. It facilitates participation of high quality international academicians for delivering short-term courses and programs in Indian institutions.
