meri saheli magazine online Published this article page no 25 India has two operational launchers Polar Satellite Launch Vehicle (PSLV) and Geosynchronous Satellite Launch Vehicle (GSLV). PSLV was developed to launch lowEarth Orbit satellites into polar and sun synchronous orbits. It has since proved its versatility by launching geosynchronous lunar and interplanetary spacecraft successfully. On the other hand GSLV was developed to launch the heavier INSAT class of geosynchronous satellites into orbit. In its third and final stage GSLV uses the indigenously developed cryogenic upper stage. Different orbits 1. Geostationary orbit (GEO) 2. Low Earth orbit (LEO) 3. Medium Earth orbit (MEO) 4. Polar orbit and Sunsynchronous orbit (SSO) 5. Transfer orbits and geostationary transfer orbit (GTO) 6. Lagrange points (Lpoints) For details refer this. Did you know that the Department of Space had also set up a separate commercial arm – New Space India Limited (NSIL) – for commercial tieups with the global space market and manage technology transfer from ISRO to industries? Indian researchers have developed a simple technique of separating the constant background of the Solar Corona and revealing the dynamic corona. The technique has been developed jointly by the Aryabhatta Research Institute and the Indian Institute of Astrophysics. What is the technique? (NOT MUCH RELEVANT FROM THE EXAMINATION POINT OF VIEW). The simple approach of subtracting the constant background can improve efficiency of identification of Coronal Mass Ejections (CME). What are Coronal Mass Ejections (CMEs)? Coronal Mass Ejections (CMEs) are large expulsions of plasma and magnetic field from the Suns corona. They can eject billions of tonnes of coronal material and carry an embedded magnetic field (frozen in flux) that is stronger than the background solar wind interplanetary magnetic field (IMF) strength meri saheli magazine online buy.
