The mission was launched by PLSV-C57 to observe the Sun from a halo orbit. 

• It was inserted in its targeted halo orbit in January 2024. 

About Aditya-L1 Mission

• Objectives: to understand:
  • Coronal Heating and Solar Wind Acceleration;
  • Initiation of Coronal Mass Ejection (CME), flares and near-earth space weather;
  • Solar wind distribution and temperature anisotropy etc.
• Placed at Lagrangian point L1: Continuously viewing the Sun without any occultation/eclipses, reduced fuel consumption etc. are the key advantages of L1. 
• 7 payloads: Four payloads directly view the Sun and three payloads carry out in-situ studies of particles and fields at L1, thus providing insights into the propagatory effect of solar dynamics in interplanetary medium. 
• Lifespan: 5 years
• Achievements: 
  • Captured images of Sun through payloads SUIT and VELC. 
  • Completion of First Halo Orbit in July. 
    • Aditya-L1 in the Halo orbit takes 178 days to complete a revolution around the L1 point.
  • Full validation for state-of-the-art flight dynamics software developed by U R Rao Satellite Centre (URSC) of ISRO for the Aditya-L1 missions.

• Parker Solar Probe launched by US in 2018 (first spacecraft to “touch” the sun) 
• Solar and Heliospheric Observatory Satellite (SOHO) mission launched Jointly by NASA-ESA (longest-lived Sun-watching satellite).
