Mission Aditya L1: ISRO activates second instrument successfully

The Indian Space Research Organisation (ISRO) on Saturday i.e. December 2 said Aditya Solar Wind Particle Experiment (ASPEX) payload onboard India’s first solar satellite Aditya-L1, has commenced its operations and started working normally.

Sharing a post on X (previously Twitter), the Indian space agency said, “The Solar Wind Ion Spectrometer (SWIS), the second instrument in the Aditya Solar wind Particle Experiment (ASPEX) payload is operational.”

ISRO also shared a graph depicting the energy variations in proton (H+) and alpha particle (doubly ionized helium, He2) counts captured by SWIS over the past two days.

The mission lifted off from Sriharikota in Andhra Pradesh on September 2. Major objectives of mission include the study of the physics of solar corona and its heating mechanism, the solar wind acceleration, coupling and dynamics of the solar atmosphere, solar wind distribution and temperature anisotropy, and origin of Coronal Mass Ejections (CME) and flares and near-earth space weather.
