Aditya L1 started collecting data (18 September 2023)
Aditya L1 status: The collection of scientific data has commenced for the Supra Thermal & Energetic Particle Spectrometer (STEPS) instrument, which is a component of the Aditya Solar Wind Particle Experiment (ASPEX) payload.
STEPS utilizes six omnidirectional sensors to measure supra-thermal and energetic ions with energies ranging from 20 keV/nucleon to 5 MeV/nucleon, and electrons exceeding 1 MeV. This comprehensive particle analysis allows for a detailed understanding of the space environment.
STEPS was activated on September 10, 2023, at a distance exceeding 50,000 km from Earth, STEPS was positioned well beyond the Earth’s radiation belt region, equivalent to over 8 times the Earth’s radius. After following essential instrument health checks, the collection of data continued until the spacecraft had traveled beyond the 50,000 km mark from Earth.

PAPA (Plasma Analyser Package for Aditya) switch on (8 December 2023)
The Plasma Analyser Package for Aditya (PAPA) installed on the Aditya-L1 spacecraft serves as an energy and mass analyzer payload designed to observe the flux of solar wind electrons and ions. It comprises two sensors: the Solar Wind Electron Energy Probe (SWEEP) for electron flux monitoring and the Solar Wind Ion Composition Analyser (SWICAR) for analyzing ion flux.
To assess the in-orbit condition, the payload underwent its initial activation on November 8, 2023, at 10 hours during the cruise phase. Notably, the high voltage (5 kV) was not enabled during this cruise phase. The functionality of the payload was tested using both the primary and backup DC-DC converters. Throughout the cruise phase, the PAPA payload’s electronics remained consistently activated. The 127 datasets obtained during this period were carefully analyzed at the Payload Operation Centre located at the Space Physics Laboratory, VSSC.
ISRO is planning to switch on the high voltage (5 kV) for the first time on December 11, 2023, and ISRO will be doing it gradually, step by step while keeping a close eye on all the parameters to ensure everything is monitored carefully.
