• ISRO will be launching the Aditya L1 mission on September 2^nd.

Lagrange Point is a spot in space where the force of gravity of the nearest celestial entities cancels each other out, helping an object remain in equilibrium.

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.
