ISRO’s Successful Mission

Topic: ISRO’s Successful Mission

Q. PSLV-C17?

Ans. PSLV-C 17 was the eighteenth successive successful flight of PSLV which has once again proved its versatility and reliability GSAT-12 Communication satellite with a mass of 1410 kg at lift-off, has 12 Extended C-band transponders and has been successfully placed in Geosynchronous Orbit.

Q. GSAT-12 and its importance?

Ans. GSAT-12 is a communication satellite with a mass of 1410 kg at lift-off, has 12 Extended C-band transponders and has been successfully placed in Geosynchronous Orbit by PSLV-C17. 

It will enhance space based applications in the area of telemedicine, tele-education and disaster management support.

Q. What is GSAT-8 and what is its role in GAGAN?

Ans. India’s advanced communication satellite, GSAT-8 - weighing about 3100 kg at lift-off, was successfully launched into the Geosynchronous Transfer Orbit (GTO) on May 21, 2011 by the Ariane-V launch vehicle from Kourou, French INSAT system and carries 24 high power transponders in Ku-band and a two-channel GPS Aided Geo Augmented Navigation (GAGAN) payload operating in L1 and L5 bands. The transponders will augment the capacity in the INSAT system while the GAGAN payload provides the Satellite Based Augmentation System (SBAS), through which the accuracy of the positioning information obtained from the GPS Satellite is improved by a network of ground based receivers and made available to the users in the country through the geostationary satellites.

Q. How many satellites were launched by PSLV-C16 and what are the details of these?

Ans. In its 17th consecutive successful flight, India’s Polar Satellite Launch Vehicle (PSLV-C16) injected three Satellites viz. RESOURCESAT-2, YOUTHSAT and X-SAT into the Polar Sun synchronous orbits on April 20, 2011 RESOURCESAT-2 built by ISRO - the primary satellite is an advanced remote sensing satellite facilitating a host of applications and services in the area of agricultural monitoring, natural resources management, disaster management support as well as infrastructure planning and will ensure continuity of remote sensing data currently being provided by RESOURCESAT-1 launched in 2003. YOUTHSAT is a joint Indo-Russian satellite for stellar and atmospheric studies. X-SAT is a micro-satellite for imaging applications built by Nanyang Technological University (NTU), Singapore.

Q. What is HYLAS (Highly Adaptable Satellite)?

Ans. The HYLAS jointly built by ISRO/Antrix and EADS/Astrium of Europe for Avanti communications of U.K. was launched successfully on November 27, 2010 by the European Ariane-5 V198 launch vehicle, and was placed in the geostationary orbit.

Q. What is the recent achievement of ISRO in Building of Super Computer

Ans. ISRO has built a supercomputer, which is to be India’s fastest supercomputer in terms of theoretical peak performance of 220 Teraflops (220 Trillion Floating Point Operations per second).

Q. What is the name of the fastest supercomputer of India which was recently built by ISRO?

Ans. The new Graphic Processing Unit (GPU) based supercomputer named “SAGA-220” (Supercomputer for Aerospace with GPU Architecture-220 Teraflops) is being used by space scientists for solving complex aerospace problems.
