ISRO likely to launch Aditya-1 Sun satellite in three years



The Aditya-1 satellite for the Sun might be launched in three years, but, with a few changes from the original plan of the mission, said Indian Space Research Organisation (ISRO).

The satellite was originally planned to be launched by 2012, but will now take place only after 2017.

“We had understood we can put the satellite in orbit from where it can see the Sun, hence increasing the observation time,” said ISRO chairman, AS Kiran Kumar.

Initially, ISRO planned to put the satellite into 800-km orbit to coincide with solar maxima on the Sun, which comes every 11 years.

ISRO will insert the satellite in a halo orbit around L1 Lagranian point of the Sun-Earth system, in order to facilitate continuous viewing of the Sun, sans eclipses.

The rocket used to place the satellite in this required orbit, is the Polar Satellite Launch Vehicle (PSLV) XL.

Kiran Kumar, on 16 June, said, the scope of the mission has been designed in such a way so as to study the Sun’s corona.

The aim of the mission is to help find out why solar flares and solar winds disturb the communication network and electronics, on Earth.

ISRO, as per a Live Mint report, plans to use the data from the satellite to better protect its satellites from being damaged by hot winds and flares, ejected out of the corona.

Meanwhile, Earth observation satellites from a UK-based company’s launch of winged reusable launch vehicle and India’s exclusive astronomical satellite with observation capabilities at multiple wavelengths, are some of the launches that are round the corner.
