Bengaluru, Jan 17: India’s latest communication satellite GSAT-30 was successfully launched from the Spaceport in French Guiana during the early hours on Friday.

In a press release, ISRO, has stated that the launch vehicle 'Ariane-5 VA-251' was blasted off from Kourou Launch Base, French Ginana at 0230 hours, carrying India’s GSA-30 and EUTELSAT KONNECT for Eutelasat, as per schedule.

With a lift-off mass of 3,357 kg, GSAT-30 will provide continuity to operational services on some of the in-orbit satellites.

GSAT-30 derives its heritage from ISRO’s earlier INSAT/GSAT satellite series and will replace INSAT-4A in orbit.

“GSAT-30 has a unique configuration of providing flexible frequency segments and flexible coverage. The satellite will provide communication services to Indian mainland and islands through Ku-band and wide coverage covering Gulf countries, a large number of Asian countries and Australia through C-band," ISRO Chairman Dr K Sivan said.

Dr Sivan also said that “GSAT-30 will provide DTH Television Services, connectivity to VSATs for ATM, Stock-exchange, Television uplinking and teleport Services, Digital Satellite News Gathering (DSNG) and e-governance applications. The satellite will also be used for bulk data transfer for a host of emerging telecommunication applications.”

ISRO’s Master Control Facility (MCF) at Hassan in Karnataka took over the command and control of GSAT-30 immediately after its separation from the launch vehicle. Preliminary health checks of the satellite revealed its normal health.

In the days ahead, orbit-raising maneuvers will be performed to place the satellite in Geostationary Orbit (36,000 km above the equator) by using its onboard propulsion system.

During the final stages of its orbit raising operations, the two solar arrays and the antenna reflectors of GSAT-30 will be deployed. Following this, the satellite will be put in its final orbital configuration.

The satellite will be operational after the successful completion of all in-orbit tests.

New Delhi, Mar 5: The primary classes of all schools in the national capital will remain closed till March 31 to prevent a possibility of spread of coronavirus, Deputy Chief Minister Manish Sisodia announced on Thursday.

According to Directorate of Education (DoE) officials, while elaborate guidelines have been issued about preventive measures for coronavirus, students of nursery and primary classes are too young to understand the risk, making them more prone to infectious diseases.

Sisodia, who also holds the education portfolio, tweeted, "As a precautionary measure to prevent the possibility of spread of COVID-19 amongst our children, Delhi Government has directed the immediate closure of all primary schools (Govt/ aided/ private/MCD/NDMC) till 31/3/20(sic)."

A senior DoE official said, "Elaborate guidelines have already been issued. However, students of nursery and primary classes are too young to understand the risks associated with COVID-19. Thus they are more prone to infectious diseases and mingle around with classmates more often."

"It will be good if they are trained in the do's and dont's under the care and supervision of their parents at home. However, students of classes other than primary will continue to come to schools or examination centres for writing their examination as per schedule. The teaching, as well as non-teaching staff, will also attend regular school," the official said.

As of now, the number of confirmed COVID-19 cases in the country stands at 30, including 16 Italian tourists. The figure includes the first three cases reported from Kerala last month who have already been discharged following recovery.

Alerted by the coronavirus case reported in Delhi-NCR, schools in the region have sent out advisories to parents suggesting that they do not send their wards to attend classes even in case of mild cough or cold, and saying that they may declare holidays if the need arises. A few schools have announced already holidays and others have advanced their spring break.
