Shimla (Himachal Pradesh) [India], September 2 : Governor Shiv Pratap Shukla has congratulated Indian Space Research Organization (ISRO) scientists on the successful launching of Aditya-L1 by PSLV-C57.
"After the success of Chandrayaan-3, India has added another dimension to its space journey," said the Governor.
He further added that this is a golden day for India when this prestigious campaign has been started with the aim of serving the entire humanity.
"It was due to the motivation and support of Prime Minister Narendra Modi, ISRO and the team involved, that the launch was successful. With this, India's reputation in space science has increased in the world," he said.
"ISRO scientists have enhanced India's prestige in the world," said Governor Shiv Pratap Shukla.
The PSLV-C57.1 rocket carrying the Aditya-L1 orbiter lifted off successfully from the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh at 11.50 am today.
"The third stage of the separation of PSLV carrying the Aditya-L1 orbiter has been completed," as per ISRO.
The launch of Aditya-L1 by PSLV-C57 is accomplished successfully, it said. The vehicle has placed the satellite precisely into its intended orbit. India’s first solar observatory has begun its journey to the destination of Sun-Earth L1 point, the agency said.
The ISRO successfully placed a lander on the unexplored lunar South Pole, a feat that put India in the record books as the first country to do so. According to the agency, the Aditya-L1 mission is expected to reach the observation point in four months.
It will be placed in a halo orbit around Lagrangian Point 1 (or L1), which is 1.5 million km away from the Earth in the direction of the sun.
It will carry seven different payloads, which will conduct a detailed study of the Sun. While 4 of the payload instruments will observe the light from the Sun, the remaining 3 will measure in-situ parameters of the plasma and magnetic fields.
The largest and technically most challenging payload on Aditya-L1 is the Visible Emission Line Coronagraph or VELC. VELC was integrated, tested, and calibrated at the Indian Institute of Astrophysics’ CREST (Centre for Research and Education in Science Technology) campus in Hosakote in collaboration with ISRO.
This strategic location will enable Aditya-L1 to continuously observe the sun without being hindered by eclipses or occultation, allowing scientists to study solar activities and their impact on space weather in real-time.
Also, the spacecraft's data will help identify the sequence of processes that lead to solar eruptive events and contribute to a deeper understanding of space weather drivers.
Major objectives of India’s solar mission include the study of the physics of solar corona and its heating mechanism, the solar wind acceleration, coupling and dynamics of the solar atmosphere, solar wind distribution and temperature anisotropy, and origin of Coronal Mass Ejections (CME) and flares and near-earth space weather.
According to the Bengaluru-based Indian Institute of Astrophysics, the atmosphere of the sun, and the Corona are seen during a total solar eclipse. A coronagraph like the VELC is an instrument that cuts out the light from the disk of the sun and can, thus, image the much fainter Corona at all times.
