Aditya-L1: ISRO says L1 point insertion to take place on January 6
ALSO READ: Aditya-L1: India’s first solar mission to reach destination, 1.5 million km from Earth, says ISRO "The Solar Wind Ion Spectrometer (SWIS), the second instrument in the Aditya Solar Wind Particle Experiment (ASPEX) payload is operational. The histogram illustrates the energy variations in proton and alpha particle counts captured by SWIS over 2-days," ISRO said in a post on X. According to the ISRO statement, the Aditya Solar Wind Particle Experiment (ASPEX) payload onboard India's Aditya-L1 satellite is performing normally.
ASPEX comprises two cutting-edge instruments - the Solar wind Ion Spectrometer (SWIS) and STEPS (SupraThermal and Energetic Particle Spectrometer). The STEPS instrument became operational on September 10, 2023. The SWIS instrument was activated on November 2, 2023, and has exhibited optimal performance, the statement mentioned.
ISRO further stated that the ASPEX has begun its measurements of solar wind ions. On 7 November, in its update, ISRO noted that the spectrometer on board Aditya-L1 recorded the impulsive phase of solar flares, during its first observation period from approximately October 29, 2023. The X-ray spectrometer, HEL1OS, attached to the Aditya-L1 spacecraft captured the first high-energy X-ray glimpse of solar flares.
