After Chandrayaan-3, ISRO To Launch Its Rs 300 Crore Sun Mission In September
With India's moon mission Chandrayaan-3 nearing its successful completion by next week, ISRO is quickly getting ready for its next big mission, The Sun.
With India's moon mission Chandrayaan-3 nearing its successful completion by next week, ISRO is quickly getting ready for its next big mission, The Sun.
The Indian Space Research Organisation (ISRO) is gearing up to launch Aditya-L1, India¡¯s first mission to the sun, by early September this year.

"Aditya-L1, the first space-based Indian observatory to study the sun, is getting ready for the launch. The satellite realised at the U R Rao Satellite Centre (URSC), Bengaluru, has arrived at SDSC-SHAR, Sriharikota," ISRO tweeted earlier this week. The Aditya-L1 mission's expected cost is Rs 378 crore.
Aditya L-1 is expected to launch in early September, which is a few weeks later than the August launch date that was expected earlier.

More About Aditya L-1 Mission
As per ISRO, Aditya L1 is the first space-based observatory-class Indian solar mission to study the Sun.
isro
The spacecraft is planned to be placed in a halo orbit around Lagrangian point 1 (L1) of the Sun-Earth system, which is about 1.5 million km from the Earth. A satellite placed in the halo orbit around the L1 point has the major advantage of continuously viewing the Sun without any occultation or eclipse. This will provide a greater advantage than observing the solar activities continuously.
The spacecraft carries seven payloads to observe the photosphere, chromosphere, and outermost layers of the Sun (the corona) using electromagnetic and particle detectors. Using the special vantage point of L1, four payloads about AdiTya-L1 directly view the sun, and the remaining three payloads carry out in-situ studies of particles and fields at Lagrange Point L1.
The Aditya L1 payloads are expected to provide crucial information to understand the problems of coronal heating, Coronal Mass Ejection, pre-flare and flare activities and their characteristics, the dynamics of space weather, the study of the propagation of particles, fields in the interplanetary medium, etc.

As per ISRO, the Aditya L-1 Sun mission has the following objectives:
Major objectives
? Understanding Coronal Heating and Solar Wind Acceleration.
? Understanding the initiation of Coronal Mass ejections (CME), flares, and near-earth space weather.
? To understand the coupling and dynamics of the solar atmosphere.
? To understand solar wind distribution and temperature anisotropy.
Uniqueness of the mission
? The first spatially resolved solar disk in the near UV band.
? CME dynamics close to the solar disk (~ from 1.05 solar radius) and thereby providing information in the acceleration regime of CME that is not observed consistently.
? On-board intelligence to detect CMEs and solar flares for optimised observations and data volume.
? Directional and energy anisotropy.
