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.

Regulator DGCA eases flight duty norms for pilots amid IndiGo crisis
Mumbai (PTI): Aviation watchdog DGCA on Friday eased the flight duty norms by allowing substitution of leaves with a weekly rest period amid massive operational disruptions at IndiGo, according to sources.
As per the revised Flight Duty Time Limitations (FDTL) norms, "no leave shall be substituted for weekly rest", which means that weekly rest period and leaves are to be treated separately. The clause was part of efforts to address fatigue issues among the pilots.
Citing IndiGo flight disruptions, sources told PTI that the Directorate General of Civil Aviation (DGCA) has decided to withdraw the provision 'no leave shall be substituted for weekly rest' from the FDTL norms.

"In view of the ongoing operational disruptions and representations received from various airlines regarding the need to ensure continuity and stability of operations, it has been considered necessary to review the said provision," DGCA said in a communication dated December 5.
The gaps in planning ahead of the implementation of the revised FDTL, the second phase of which came into force from November 1, have resulted in crew shortage at IndiGo and is one of the key reasons for the current disruptions.
