With the Indian Space Research Organisation (ISRO) efficiently inserting the Aditya-L1 spacecraft in a halo orbit across the Lagrangian level (L1) on January 6, the focus is now on the operation of the scientific devices and data collection.
Aditya-L1 is a satellite tv for pc devoted to the excellent examine of the sun with seven payloads.
The seven payloads aboard the satellite tv for pc are: Visible Emission Line Coronagraph (VELC), Solar Ultraviolet Imaging Telescope (SUIT), Solar Low Energy X-ray Spectrometer (SoLEXS), High Energy L1 Orbiting X-ray Spectrometer (HEL1OS) , Aditya Solar wind Particle Experiment (ASPEX), Plasma Analyser Package For Aditya (PAPA) and Advanced Tri-axial High Resolution Digital Magnetometers.
According to the ISRO, a satellite tv for pc placed in the halo orbit across the L1 level has the foremost benefit of constantly viewing the sun with none occultation/eclipses.
Greater benefit
This will present a larger benefit of observing the photo voltaic actions and its impact on area climate in actual time. The spacecraft carries seven payloads to watch the photosphere, chromosphere and the outermost layers of the sun (the corona) utilizing electromagnetic and particle and magnetic area detectors.
The payloads have been switched on and a few of them have already collected data.
The Supra Thermal and Energetic Particle Spectrometer instrument, part of the ASPEX payload, had begun the collection of scientific data in September 2023.
The HEL1OS has recorded the impulsive section of photo voltaic flares; Aditya Solar wind Particle Experiment (ASPEX) payload has additionally commenced its operations; the Solar Ultraviolet Imaging Telescope (SUIT) instrument has efficiently captured the primary full-disk photos of the sun in the 200-400 nm wavelength vary.
The Visible Emission Line Coronagraph (VELC), which is the first payload of the spacecraft, was additionally switched on throughout the cruise section.
VELC, developed by the Indian Institute of Astrophysics (IIA), Bengaluru, will be capable of observe the corona constantly from the L1. VELC could be sending 1,440 photos of the sun in a day.
“The VELC payload was switched on and tested during the cruise phase. Once the spacecraft is in halo orbit we have to carry our tests to ensure that everything is alright before we commence the experiments. Once we make sure that the instrument is pointed towards the centre of the sun we have to carry out all the calibration observations and the performance of all the electronic components onboard would also be tested,” Ramesh. R, principal investigator of the VELC payload, instructed The Hindu.
Mr. Ramesh added that the VELC payload is probably to begin sending photos by the tip of January.
