Thiruvananthapuram: The ISRO is one step closer to launching GSLV Mk-III, with the indigenously-developed cryogenic engine to be used in it successfully completing one of its final tests on Friday.
The engine endured the hot test for 640 seconds, which is the full flight duration, at ISRO Propulsion Research Complex, Mahendragiri.
ISRO chairman A.S. Kiran Kumar in his address to the gathering present at Mahendragiri said, “a phenomenal achievement in the shortest time. Fully
indigenous cryogenic engine development for GSLV Mk-III and
major step towards GSLV Mk-III launch in December 2016.”
The engine will now be integrated into the full stage and tested. Earlier in the day, the chairman said in a press meet in Thiruvananthapuram that they were aiming
at achieving a flight test in December. This is the second time that a fully indigenous cryogenic engine is being tested for mission duration.
Electric Propulsion System: The ISRO is developing an electric propulsion system to be used in satellites, said Mr Kiran Kumar. The system, in comparison with a liquid propulsion system, weighs less.
This can increase the number of transponders, and therefore the payload of the satellites. It will be first experimented on GSAT-9 satellite in two years.
Initially it will be used only for station-keeping purposes like adjusting the orbit of the satellite. The aim, however, is to fully replace liquid fuel with it.
Next Launch: The last two of the seven-satellite-constellation of Indian Regional Navigation Satellite System (IRNSS) will be launched on March 10 and March 31.
Lithium Ion Cells in Buses: Lithium ion cells, used in spacecraft, will be powering buses in the near future. ISRO is developing a cost-effective technology for the same, with the support of Automobile Research Association of India (ARAI), Pune.
Increasing Frequency of Launches: The ISRO chairman said that the capability of ISRO facilities will be raised to increase the launch frequency. Next year, a new vehicle assembly area will come up. The ISRO is also planning to add a new launch pad in the future.
