Aditya L1: India's Mission to Save the Earth

1. Purpose: The Aditya L1 mission is India's first effort to study the dynamics of the solar upper atmosphere (chromosphere and corona), launched by ISRO.

2. Orbit: The spacecraft will be positioned in a halo orbit around Lagrange point 1 (L1), 1.5 million km from Earth.

3. Objectives: Study solar upper atmosphere dynamics, chromospheric and coronal heating, CMEs, and flares.

4. Payloads :Seven instruments including a coronagraph, spectrometer, spectrograph, magnetometer, plasma analyzer, particle detector, and radiometer.

5. Launch Date: Set for September 2, 2023 from Satish Dhawan Space Centre, Sriharikota, Andhra Pradesh.

6. Journey: Estimated four-month journey to travel 1.5M KM's (four times the distance covered by Chandrayaan-3) for the spacecraft to reach the L1 point.

7. Duration: The mission is projected to last five years. To study the development, dynamics, and origin of coronal mass ejections (CMEs)

8. Insights: Expected to yield insights into solar workings and its influence on Earth, aiding understanding of space weather.

9. Data Use: Mission data will improve knowledge of solar storms and space weather's effects on Earth's atmosphere and climate.

10. Impact: A significant step in advancing space research and technology for India.
