Aditya-L1’s first earth-bound firing to raise orbit successful, says ISRO

The Indian Space Research Organization (ISRO) on Sunday said the first launch from Earth to raise the orbit of Aditya-L1 has been successfully completed.
The space agency has confirmed that the satellite is in good working order.
In a message on X, ISRO said: “The first Earth exercise (EBN#1) has been successfully completed from ISTRAC, Bengaluru. The newly achieved orbit is 245km x 22,459km. The next (EBN#2) is scheduled for September 5, 2023, around 03:
00 hours. IST.”
The Aditya-L1 orbiter PSLV-C57.1 rocket successfully lifted off from the Satish Dhawan Space Center in Sriharikota, Andhra Pradesh at 11:50 a.m. Saturday.
“Nth stage.” three of the PSLV-carrying separations According to ISRO, the Aditya-L1 orbiter has been completed. The vehicle correctly placed the satellite in the intended position. India’s first solar observatory has begun its journey to point L1 of the Sun-Earth.
The successful launch of ISRO’s first solar mission follows the historic moon landing mission – Chandrayaan-3.
ISRO has successfully placed a lander on the unexplored lunar South Pole, a feat that has put India in the record books as the first country to do so.

According to the agency, the Aditya-L1 mission will reach the observation point in four months.
It will be placed in a halo orbit around the Lagrange 1 (or L1) point, located 1.5 million kilometers from Earth in the direction of the sun.
It will carry seven different payloads, making it possible to make detailed studies of the Sun. While four payload devices will observe sunlight, the other three will measure plasma and magnetic field parameters in situ.
The largest and most technically challenging payload on the Aditya-L1 is the Visible Emission Line or VELC. VELC has been integrated, tested and calibrated at the campus of the Indian Institute of Astrophysics CREST (Center for Science and Technology Research and Education) in Hosakote. in collaboration with ISRO.
This strategic location will allow Aditya-L1 to observe the sun continuously without being obstructed by eclipses or eclipses, allowing scientists to study the sun’s activities and their effects to space weather in real time.
In addition, spacecraft data will help determine the sequence of processes leading to solar flare events and contribute to a deeper understanding of space weather factors.


The main objectives of the Indian solar mission include the study of the physics of the solar halo and its heating mechanism, the acceleration of the solar wind, the coupling and dynamics of the solar atmosphere, the distribution of the solar wind and temperature anisotropy, as well as the origin of the coronal mass ejection (CME). ) and flares and near-Earth space weather.
According to the Bengaluru-based Indian Institute of Astrophysics, the sun’s atmosphere and corona are visible during a total eclipse. A corona like VELC is an instrument that cuts light from the sun’s disk and can therefore take a much dimmer image of the halo at any time.
