ISRO's Space Physics Laboratory (SPL) is responsible for conducting experimental studies in space physics, planetary sciences, and astrophysics. It develops scientific instruments for satellites and spacecraft and provides data analysis from various missions. SPL’s role in the upcoming Chandrayaan-3 Mission is to provide a scientific instrument called LUS (Lunar Ultraviolet Spectrometer). LUS aims to detect the elemental composition of the lunar surface and its exosphere, which will help in understanding the evolvement of the Moon. Significance of ISRO's Space Physics Laboratory in the Chandrayaan-3 Mission:

• LUS will help in understanding the origin and evolution of the Moon.
• LUS will provide information on the composition of the lunar surface, which will help in understanding the formation and evolution of the Moon.
• LUS will also help in studying the lunar exosphere, which will provide information on the lunar atmosphere and its interaction with the solar wind.
• Overall, LUS's data will help in understanding the Moon's geology and its connection with the solar system's history, including the origin and evolution of life.

ISRO's Space Physics Laboratory's contribution to the Chandrayaan-3 Mission is essential for the success of India's Moon exploration program, which aims to expand our knowledge of the Moon and its role in the solar system's evolution.
