Aditya-L1 is the second spacecraft that the ISRO could send outside the sphere of influence of the Earth. The first one was the Mars Orbiter Mission.
It carries seven payloads. While four payloads will observe light from the Sun, three payloads will measure in-situ (in original position) parameters of the plasma and magnetic fields.
Aditya-L1 will be placed in a halo orbit around L1 in the direction of the Sun. It would revolve around the Sun with the same relative position and hence can see the Sun continuously.
ASPEX comprises two cutting-edge instruments – the Solar wind Ion Spectrometer (SWIS) and STEPS (SupraThermal and Energetic Particle Spectrometer).
The STEPS instrument was operational on September 10 this year, while the SWIS instrument was activated on November 2, last month, and has exhibited optimal performance, ISRO said.
SWIS, utilising two sensor units with a 360° field of view each, operates in planes perpendicular to one another.
