The spacecraft shall be placed in a halo orbit around the Lagrange point 1 (L1) of the Sun-Earth system, which is about 1.5 million km from the Earth.Â
BENGALURU: Indian Space Research Organisation (ISRO) on Monday announced that it will launch the Aditya-L1 Solar Mission. The first space-based Indian observatory to study the Sun on September 2, 2023. The launch of the solar mission will take place on September 2, 2023, at 11:50 am from Sriharikota. Taking to X (former Twitter), ISRO said, “The launch of Aditya-L1, the first space-based Indian observatory to study the Sun, is scheduled for September 2, 2023, at 11:50 Hrs. IST from Sriharikota. Citizens are invited to witness the launch from the Launch View Gallery at Sriharikota by registering here: https://lvg.shar.gov.in/VSCREGISTRATION/index.jsp. Commencement of registration will be announced there.”
Aditya L1 shall be the first space-based Indian mission to study the Sun. We shall place the spacecraft in a halo orbit around the Lagrange point 1 (L1) of the Sun-Earth system. Which is about 1.5 million km from the Earth. A satellite placed in the halo orbit around the L1 point has the major advantage of continuously viewing the Sun without any occultation/eclipses. This will provide a greater advantage in observing solar activities and their effect on space weather in real-time.
The spacecraft carries seven payloads to observe the photosphere, chromosphere and the outermost layers of the Sun (the corona) using electromagnetic particle and magnetic field detectors. ISRO also mentioned the objectives of Aditya-L1 mission.
“Study of Solar upper atmospheric (chromosphere and corona) dynamics. Study of chromospheric and coronal heating, physics of the partially ionized plasma, initiation of the coronal mass ejections, and flares. Observe the in-situ particle and plasma environment providing data for the study of particle dynamics from the Sun,” an official statement issued by ISRO said.
“Physics of solar corona and its heating mechanism. Diagnostics of the coronal and coronal loops plasma: Temperature, velocity and density. Development, dynamics and origin of CMEs. Identify the sequence of processes that occur at multiple layers (chromosphere, base and extended corona) which eventually leads to solar eruptive events. Magnetic field topology and magnetic field measurements in the solar corona. Drivers for space weather (origin, composition and dynamics of solar wind,” it added.
On the evening of September 23, India achieved a significant milestone as the Chandrayaan-3 lander module gracefully and successfully touched down on the moon’s South Pole, marking a remarkable leap forward in its space exploration efforts. This remarkable achievement marked India as the first country to accomplish this historic feat. Bringing an end to the disappointment caused by the Chandrayaan-2 crash landing four years ago. This success showcases India’s prowess in space exploration. Additionally, it’s worth noting that India has now positioned itself as the fourth country to accomplish a successful moon landing, trailing behind the US, China, and Russia. This achievement is particularly significant.
