Aditya – L1 Solar Mission

• The Indian Space Research Organization is working on Aditya L1 space project that will study the sun.
• The Aditya spacecraft will study solar magnetic storms and the impact of the solar atmosphere on the earth.
• About Aditya L1: The spacecraft is to study the following:

1. Solar Winds: These winds are created due to the expansion of the sun’s plasma
2. Photosphere and Chromosphere– Layers of the sun
3. Corona of the sun
4. Energetic particles of the sun
5. Coronal heating: The coronal heating problem in solar physics relates to the question of why the temperature of the Sun’s corona is millions of kelvins versus the thousands of kelvins of the surface. The Aditya L-1 spacecraft will help Indian space scientists find solutions to the coronal heating problem.

Lagrange Points

• Lagrange Points are positions in space where the gravitational forces of a two-body system like the Sun and Earth produce enhanced regions of attraction and repulsion.
• These can be used by spacecraft as “parking spots” in space to remain in a fixed position with minimal fuel consumption. In simple terms, Lagrange points are positions in space where objects sent there tend to stay put.
• At Lagrange points, the gravitational pull of two large masses precisely equals the centripetal force required for a small object to move with them.
• Name and discovery– Lagrange points (L1, L2, L3) were discovered by the Swiss mathematician Leonhard Euler around 1750, a decade before the Italian-born Joseph-Louis Lagrange discovered the remaining two. In 1772, Lagrange published an “Essay on the three-body problem”.
