What it studies
It carries instruments to study the solar corona, solar wind, solar flares and space weather, which affect satellites and communications on Earth.
Why it matters
Understanding solar activity helps protect space-based and ground-based technology from geomagnetic storms.
Why it matters for UPSC
The concept of Lagrange points, the L1 location and the mission's objectives are testable Science & Technology and current-affairs facts.
