Chennai: Indian Satellite - Satish Dhawan Satellite - (SD Sat) is set to carry the names of common people across the world to space in an effort to create awareness, generate curiosity and to get more people fascinated about space science.
He also said that the Indian Space Research Organisation (ISRO) is looking at green propulsion through hydrogen peroxide in its rocket that would take Indians into the space under its Gaganyaan mission. Since humans will be inside the rocket, we want only non-hazardous fuel and not the hazardous one to power the human space mission s Gaganyaan rocket, ISRO chief K Sivan, who is also Secretary in Department of Space, told IANS. According to him, ISRO is also looking at rocket engines powered by hydrogen peroxide as a mono-propellant or as a bi-propellant along with ethanol. ISRO is also developing another green fuel - LOX/Methane- liquid oxygen as oxidiser and methane as fuel.
Largest study of Asia’s rivers may help predict changes in region’s water cycle: Scientists
Agencies
December 31, 2020 Mega-droughts of the past have often simultaneously hit sites that are currently home to power production along Asian rivers, says the largest study of the continent s river systems which may help predict long term changes in the region s water cycle.
The study, published in the journal Water Resources Research, noted that the findings have important implications for water management and power production, especially when a country s economy depends on multiple river basins. Our records show that mega-droughts have hit multiple power production sites simultaneously, so we can now use this information to design a grid that is less vulnerable during extreme events, said study co-author Stefano Galelli from Singapore University of Technology and Design (SUTD).
