India successfully launched this Saturday its first space mission to study the Sunthe launch, which represents a new achievement for the Asian country’s space program, which last week became the first country to land on the moon’s south pole.
takeoff Probe Aditya-L1 (Sun in Sanskrit) with polar satellite launcher (PSLV) occurred at 11:50 (6:20 am GMT) from the center of Sriharikota in the southeastern state of Andhra Pradesh, the Indian Space Research Organization (ISRO) showed a live broadcast during the countdown.
“Congratulations, Aditya-L1 has been launched into an elliptical orbit (…), which was very precisely intended by PSLV,” said the head of ISRO, Sridhara Paniker Somanathfrom the control center after confirming the success of the takeoff.
“From now on, Aditya-L1 will set off., after some maneuvers on the ground it will start its way to point L1. A very long journey, almost 125 days,” he added.
The probe will remain in orbit for 16 Earth Dayswhich it will use to gradually pick up speed before heading to its final destination: the first Lagrange point (L1), the place between the Sun and the Earth, separated from our planet by 1.5 million kilometers.
Mission it will take about four months to reach this pointwhich is barely 1% of the distance separating the two celestial bodies, and which is gravitationally stable, since the attraction of the Sun and the Earth is in equilibrium, which allows you to continue watching the star without being affected by eclipses or obscurations.
from there, Aditya-L1 will study the outer layers of the Sun, the photosphere, chromosphere and corona.with seven payloads that will use electromagnetic detectors, particle detectors and magnetic fields, according to ISRO.
The purpose of these tools is “to provide information that will help understand coronal heating issuescoronal mass ejection, pre-solar flare activity and its characteristics, space weather dynamics, particle and field propagation studies in the interplanetary medium,” the Indian Space Agency continued.
The Aditya-L1 weighs 1480.7 kilograms and is expected to last about five years.
While ISRO did not release a budget for the mission, local media estimated that is about 4000 croreswhich is equivalent to more than $48 million.
With this mission, India joins a select group of countries that have sent probes to study the Sun, including China, USA, Japan or extinct West Germany (in cooperation with NASA), as well as the European Space Agency (ESA).
Prime Minister of India, Narendra Modicongratulated ISRO scientists on X (formerly Twitter) “on the successful launch of India’s first solar mission” and recalled that this new journey complements the country’s recent success with its Chandrayaan-3 mission to the Moon.
The launch of Aditya-L1 will take place ten days after Historic Indian probe landing on the uncharted South Pole. Moon as part of the ISRO Chandrayaan-3 mission, which made the Asian country the first country to reach the southernmost part of the Earth’s satellite.
