ISRO successfully launched its much-anticipated ‘Aditya-L1’ mission to Sun from Satish Dhawan Space Centre, Sriharikota on Sept 02. ‘Aditya-L1’ is India’s first space-based Indian observatory mission to study the Sun. Spacecraft is carrying 7 payloads to observe the photosphere, chromosphere, outermost layers of Sun. ‘Aditya-L1’ is going to travel a distance of 1.5 million km from Earth, about four times farther than the Moon. Initially, spacecraft will be placed in a low earth orbit; subsequently, using an on-board propulsion system, it will be put in Lagrange point L1. The total travel time from launch pad to L1 will take about four months for ‘Aditya-L1’.
