Bengaluru: India will launch a Gsat-30 heavy communications satellite from the Kourou space center in French Guiana on January 17 on board an Ariane 5 rocket from the European Space Agency (Arianespace), said ISRO chief K. Sivan on Wednesday.

"The launch of Gsat-30 from Kouru will be our first satellite in the new year (2020) to increase the capacity to provide communications links for government and private service providers," the Indian Space Research Organization (ISRO) chairman told reporters ,

Paris-based Arianespace launched the Gsat-31 space agency on February 6, 2019 with a 1-2K bus structure to provide geostationary orbital communication services in the Ku-Band for 15 years.

Sivan also said, "We are planning 25 launches this year, including the Aditya-L1 satellite, which will be in a halo orbit around Lagrange point (L1), approximately 1.5 million km from Earth.

Aditya will study the solar corona, which represents the outer layers of the sun and extends up to thousands of kilometers above the disk (photosphere or corona).

"The corona has a temperature of over a million Kelvin, which is higher than the sun disk temperature of 6,000 K. How the corona is heated to such high temperatures is still an unanswered question in solar physics," ISRO said in an earlier statement ,

Aditya will also study the chromosphere (ultraviolet) and the particle flow that comes from the sun and reaches the L1 orbit.

The magnetometer's payload measures the change in magnetic field strength at the atrium by L1.

Further launches during the year include SSLV (Small Satellite Launch Vehicle) for placing smaller satellites (500 kg and less) in the lower earth orbit, GSLV with 4-meter OGIVE payload fairing (heat shield), GSAT-20 satellite, NavIC with indigenous Character atomic clocks, Indian Data Relay Satellite System and Xposat.

"We carried out six rocket and seven satellite missions in 2019, and the Polar Space Launch Vehicle (PSLV), the space agency's workhorse, launched in the same year," said Sivan.
