ISRO gearing up for mission to study Sun, satellite arrives for launch

AdityaL1 the first spacebased Indian observatory to study the Sun is getting ready for its launch soon ISRO said on MondayThe satellite realised at U R Rao Satellite Centre has arrived at the ISROs spaceport in Sriharikota in Andhra Pradesh the Bengaluruheadquartered national space agency said in an update on the missionMostly September first week an ISRO official told PTI when asked about the date of the launchThe spacecraft is expected to be placed in a halo orbit around the Lagrange point 1 L1 of the SunEarth system which is about 15 million kilometres from the EarthA satellite placed in the halo orbit around the L1 point has a major advantage of continuously viewing the Sun without any occultationeclipses ISRO noted This will provide a greater advantage of observing the solar activities and its effect on space weather in real time it saidThe spacecraft carries seven payloads to observe the photosphere chromosphere and the outermost layers of the Sun the corona using electromagnetic and particle and magnetic field detectorsUsing the special vantage point L1 four payloads will directly view the Sun and the remaining three payloads would carry out insitu studies of particles and fields at the L1 thus providing important scientific studies of the propagatory effect of solar dynamics in the interplanetary mediumThe suits of Aditya L1 payloads are expected to provide most crucial information to understand the problem of coronal heating coronal mass ejection preflare and flare activities and their characteristics dynamics of space weather propagation of particle and fields etc ISRO saidThe major science objectives of the AdityaL1 mission are study of solar upper atmospheric chromosphere and corona dynamics study of chromospheric and coronal heating physics of the partially ionised plasma initiation of the coronal mass ejections and flares observe the insitu particle and plasma environment providing data for the study of particle dynamics from the Sun physics of solar corona and its heating mechanism diagnostics of the coronal and coronal loops plasma temperature velocity and density development dynamics and origin of coronal mass ejections identify the sequence of processes that occur at multiple layers chromosphere base and extended corona which eventually leads to solar eruptive events magnetic field topology and magnetic field measurements in the solar corona drivers for space weather origin composition and dynamics of solar windThe instruments of AdityaL1 are tuned to observe the solar atmosphere mainly the chromosphere and corona while the insitu instruments will observe the local environment at L1This story has been sourced from a third party syndicated feed agencies Midday accepts no responsibility or liability for its dependability trustworthiness reliability and data of the text Midday managementmiddaycom reserves the sole right to alter delete or remove without notice the content in its absolute discretion for any reason whatsoever
