India's Aditya-L1 space-based solar observatory has started collecting scientific data, according to the Indian Space Research Organisation (ISRO). The Supra Thermal & Energetic Particle Spectrometer (STEPS) instrument is measuring supra-thermal and energetic ions and electrons at distances more than 50,000 km from Earth. The data collected will help scientists analyse the behaviour of particles surrounding Earth. STEPS, a part of the Aditya Solar Wind Particle EXperiment (ASPEX) payload, consists of six sensors observing in different directions and measuring ions and electrons at various energy levels.
