Indian Space Agency to Work on Electric Propulsion for Large Satellites

The Indian Space Research Organisation (ISRO) is set to work on incorporating and utilizing electric propulsion in its spacecraft which will be more cost effective and can help in interplanetary missions. Electric propulsion system will replace the currently used chemical propellants.

Unlike chemical propulsion, electric propulsion is not limited in energy which can send spacecraft to a longer distance at low level thrust with very little mass.

"Our plan is to use GSLV Mk III (Geosynchronous Satellite Launch Vehicle-Mark III) for our future satellite launches. We have started having electric propulsion for our satellites, which will reduce their weight," ISRO chairman AS Kiran Kumar said after the successful launch of India's heaviest satellite from domestic launch system GSLV MK III - designed and realized by ISRO engineers. The rocket does not have any foreign or borrowed technology.

Till today, we had the capability to launch 2.2 ton satellites and in GSLV-MKIII D1 launch, we have successfully used electric propulsion system, he added.

"Electric propulsion is a cost effective way to send large satellites into space. Though electric propulsion system sends satellites into space at low speed, it can send satellite at large distance using minimum propellants. As ISRO has planned interplanetary mission, it will be very useful," MN Vahiya, scientist at the Tata Institute of Fundamental Research, said.

Currently, ISRO had to depend on foreign facilities to send heavier satellites like that in Ariane, French Guiana. On June 28, ISRO will send its next satellite 3.3 ton satellite GSAT18 from French Guiana.

The same facility will be also used for another satellite weighing 5.8 ton. "We have a six-ton satellite in principle. It is possible to be realized using electric propulsion. So we have already started using electric propulsion system. (Even) GSAT-19 (launched on Monday) carries an electric propulsion system. So, we have successfully tested that," Kiran Kumar said.

ISRO has two interplanetary missions 'Aditya' for the sun and 'Chandrayaan II' for the moon. "The launch of Chandrayaan II will be in the first quarter of next year and with regard to Aditya, we are planning to launch it sometime in 2018-19," Kumar said.

"Every space agency in the world is trying to gain expertise in this technology but nobody can claim to have mastery in this field. We have knowledge of the technology and are working on relentlessly on how to control it. If and when we command the technology, ISRO will be able to plan more missions at a very low cost," Vahiya said.

Study proves viability of quantum satellite communications
Washington DC (SPX) Jun 07, 2017
Researchers in Canada have taken a significant step towards enabling secure quantum communication via moving satellites, as announced by the Canadian Government in April 2017. Their study, published in the new journal Quantum Science and Technology, demonstrates the first quantum key distribution transmissions from a ground transmitter to a quantum payload on a moving aircraft.
