India will launch a heavy communication satellite Gsat-30 on January 17
India will launch a heavy communication satellite Gsat-30 on January 17 from Kourou space centre in French Guiana on board an Ariane-5 rocket of the European Space Agency (Arianespace), ISRO chief K. Sivan said on Wednesday.
“The launch of Gsat-30 from Kouru will be our first satellite in the New Year (2020) to augment capacity to provide communication links to state-run and private service providers,” the Indian Space Research Organisation (ISRO) chairman told reporters here.
Sivan also said: “We are planning to have 25 launches this year, including Aditya-L1 satellite, which will be inserted in a halo orbit around the Lagrangian point (L1), about 1.5 million km from the earth.
Aditya will study the solar corona, which is the outer layers of the sun, extending to thousands of km above the disc (photsphere or corona).
“The corona has more than a million degree Kelvin temperature, which is higher than the solar disc temperature of 6,000K. How the corona gets heated to such high temperatures is still an unanswered question in solar physics,” said ISRO
Aditya will also study the Chromosphere (ultra-violent) and the particle flux emanating from the sun and reaching the L1 orbit. The magnetometer payload will measure the variation in magnetic field strength at the halo around L1.
Other launches during the year include SSLV (Small Satellite Launch Vehicle to place smaller satelliers (500kg and less) in the earth’s lower orbit, GSLV with 4-metre ogive payload fairing (heat shield), GSAT-20 satellite, NavIC with indigenous atomic clocks, Indian Data Relay Satellite System and Xposat.
