Question: Write explanatory note on “Aditya” Mission of Indian Space Research Organisation. ( 4 marks/ 120 words)

Answer:

The Aditya mission is a national effort with the collaboration of ISRO, IIA, Udaipur Solar Observatory, ARIES, TIFR and some other Indian institutions. Aditya-L1 is the first observatory-class space-based solar mission from India.

The spacecraft will be placed in a halo orbit around the first Lagrange point, L1, of the Sun-Earth system. A satellite around the L1 point has the major advantage of continuously viewing the sun without occultation/eclipses.

Aditya L1 Mission Objectives

Aditya L1’s mission objective is to study the Corona, Chromosphere, and Photosphere of the Sun. Additionally, it will research changes in magnetic field strength and the particle flow coming from the sun.

• To understand the Coronal Heating (visual and NIR) and Solar Wind Acceleration.
• To study the particle flux emanating from the Sun.
• To research the coupling and dynamics of the Solar Atmosphere.
• To help track the storms directed towards the earth and predict their impact.
• To study the Sun’s photosphere (soft and solid X-rays) and chromosphere (UV) and carry out 24/7 imaging of the Sun.

Aditya-L1 carries seven payloads to observe the photosphere, chromosphere, and the outermost layers of the sun (the corona) using electromagnetic and particle detectors.
