ABOUT ADITYA L1 MISSION

Aditya-L1 will be the 1^st Indian space mission to study the sun.
It will be launched by Polar Satellite Launch Vehicle (PSLV).
Spacecraft shall be placed in a halo orbit about 1.5 million km from Earth around Lagrangian point 1 (L1) of the Sun-Earth system.
Objective– Aditya L1 will study the Sun’s corona, Sun’s photosphere, chromosphere, solar emissions, solar winds and flares, and Coronal Mass Ejections (CMEs), and will carry out round-the-clock imaging of the Sun.
The 7 payloads include:
- Visible Line Emission Coronagraph (VLEC)
- Solar Ultraviolet Imaging Telescope (SUIT)
- Solar Low Energy X-ray Spectrometer (SoLEXS)
- High Energy L1 Orbiting X-ray Spectrometer (HEL1OS)
- Aditya Solar wind Particle Experiment (ASPEX)
- Plasma Analyser Package for Aditya (PAPA)
- Advanced Tri-axial High Resolution Digital Magnetometers
Note- VELC,SUIT, SoLEXS and HEL1OS are remote sensing payloads whereas ASPEX, PAPA and Magnetometers are in-situ payloads.
