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.

Assam to lift all cases against Koch Rajbongshis in Foreigners' Tribunals: CM Himanta Biswa Sarma
Guwahati, Apr 4 (PTI): The Assam cabinet has decided to lift all cases pending against people from the Koch Rajbongshi community in the Foreigners' Tribunals, Chief Minister Himanta Biswa Sarma said on Friday.
They will also no longer carry the tag of 'D' or doubtful voters, he said.
''There are 28,000 cases pending in different Foreigners' Tribunals in the state against people of the community. The cabinet has taken a historic decision of lifting the cases with immediate effect,'' Sarma said at a press conference here after the cabinet meeting.
The government believes that the Koch Rajbongshis are an indigenous community of the state and they are an inextricable part of ''our social and cultural fabric'', he asserted.
The people of this community are poor and have suffered a lot over the years, he said.
''They will no longer carry the tag of foreigners or ‘D’ voters,'' the CM said.
Foreigners Tribunals are quasi-judicial bodies, particularly in Assam, established to determine if a person residing in India is a "foreigner" as defined by the Foreigners Act of 1946, based on the Foreigners (Tribunals) Order of 1964.
These tribunals are designed to address matters related to citizenship and the presence of “foreigners” in India, specifically focusing on cases where someone is suspected of being an illegal immigrant.
There are 100 Foreigners’ Tribunals across Assam.
The Koch Rajbongshis have a sizeable presence in Assam, West Bengal, Meghalaya, and parts of Bangladesh, Nepal, and Bhutan, and they demand Scheduled Tribe status.
