The Aditya Solar wind Particle Experiment payload onboard India’s Aditya-L1 satellite has commenced its operations and is performing normally, ISRO said on Saturday.
ISRO’s Polar Satellite Launch Vehicle (PSLV-C57) on September 2 had successfully launched the Aditya-L1 spacecraft, from the second launch pad of Satish Dhawan Space Centre, Sriharikota.
Aditya-L1 is the first Indian space-based observatory to study the Sun from a halo orbit around first Sun-earth Lagrangian point (L1), which is located roughly 1.5 million km from Earth.
In a statement, ISRO said Aditya Solar wind Particle Experiment (ASPEX) comprises two cutting-edge instruments ‘the Solar Wind Ion Spectrometer (SWIS) and SupraThermal and Energetic Particle Spectrometer (STEPS). The STEPS instrument was operational on September 10, 2023. The SWIS instrument was activated on November 2, 2023, and has exhibited optimal performance.
“SWIS, utilising two sensor units with a remarkable 360 field of view each, operates in
