ISRO completes launch rehearsal of Aditya-L1 solar mission
Bengaluru (PTI): Giving an update on its Aditya-L1 mission to study the Sun, ISRO said on Wednesday the launch rehearsal and the rocket's internal checks have been completed.
The mission is scheduled to be launched on September 2 at 11.50 am from the Sriharikota spaceport.
Aditya-L1 spacecraft is designed for providing remote observations of the solar corona and in situ observations of the solar wind at L1 (Sun-Earth Lagrangian point), which is about 1.5 million kilometres from the earth.
It will be the first dedicated Indian space mission for observations of the Sun to be launched by the Bengaluru-headquartered space agency.
The spacecraft -- the first space-based Indian observatory to study the Sun -- would be launched by PSLV-C57 rocket.
"The preparations for the launch are progressing", ISRO said in a social media post today. "The Launch Rehearsal - Vehicle Internal Checks are completed".
The Aditya-L1 mission, aimed at studying the Sun from an orbit around the L1, would carry seven payloads to observe the photosphere, chromosphere and the outermost layers of the Sun, the corona, in different wavebands.
Aditya-L1 is a fully indigenous effort with the participation of national institutions., an ISRO official said.
The Bengaluru-based Indian Institute of Astrophysics (IIA) is the lead institute for the development of Visible Emission Line Coronagraph payload. Inter-University Centre for Astronomy and Astrophysics, Pune, has developed the Solar Ultraviolet Imager payload for the mission.
Aditya-L1 can provide observations on the corona, and on the solar Chromosphere using the UV payload and on the flares using the X-ray payloads. The particle detectors and the magnetometer payload can provide information on charged particles and the magnetic field reaching the halo orbit around L1.

Maharashtra: All files to be vetted by Shinde before being sent to CM Fadnavis
Mumbai (PTI): The Maharashtra government has ordered that all files will now go through Deputy Chief Minister Eknath Shinde before being presented to CM Devendra Fadnavis for approval.
The moves seeks to revive an arrangement which existed in 2023 of files being vetted by the then two deputy CMs --Ajit Pawar and Fadnavis -- before being forwarded to then CM Shinde.
State Chief Secretary Sujata Saunik issued an order to this effect on March 18. "Since July 26, 2023, files were moved from Deputy Chief Minister Ajit Pawar, who holds the finance department, to (then) Deputy CM Fadnavis, who held the home, law and judiciary departments before being sent to (then) CM Shinde for approval," as per the order.
This arrangement was made after Pawar, who was then leader of opposition in the state assembly, joined the Shinde-led government along with a several NCP MLAs on July 2, 2023.
Now, with Fadnavis taking charge as chief minister, following the victory of the Mahayuti (comprising BJP, Shinde's Shiv Sena and Pawar-led NCP) in the state polls last year, the arrangement has been changed.
All files will be routed from Deputy CM Ajit Pawar, who continues to hold the finance department, to Eknath Shinde, who is also the deputy CM and holds housing and urban development portfolios.
The files will be sent to Fadnavis after Shinde's approval, as per the latest order.
Since the Mahayuti 2.0 took over, there has been speculation of a "cold war" between Shinde and Fadnavis. Both the leaders have strongly denied the speculation.
There have been disagreements over the guardian minister posts of some districts. Fadnavis had to revoke his decision on the appointment of guardian ministers of Nashik and Raigad districts after objections from Shinde.
