[Geo4All] The launch of Aditya-L1 is accomplished successfully

[Suchith Anand]

Dear colleagues,


India's first solar mission, Aditya-L1, was successfully launched from the Satish Dhawan Space Centre in Sriharikota on Saturday, September 2, 2023. The next 4 months will see the spacecraft travelling a distance of 1.5 million kilometers from earth before finally reaching its intended orbit.


Aditya L1 shall be the first space based Indian mission to study the Sun. 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. 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 of observing the solar activities and its 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 and particle and magnetic field detectors. Using the special vantage point L1, four payloads directly view the Sun and the remaining three payloads carry out in-situ studies of particles and fields at the Lagrange point L1, thus providing important scientific studies of the propagatory effect of solar dynamics in the interplanetary medium.


The suits of Aditya L1 payloads are expected to provide most crucial informations to understand the problem of coronal heating, coronal mass ejection, pre-flare and flare activities and their characteristics, dynamics of space weather, propagation of particle and fields etc.

This mission is a testament to India's unwavering commitment to advancing scientific knowledge.

The successful launch of Aditya-L1 is a testament to the hard work and dedication of the scientists and engineers at ISRO. It is also a proud moment for India, as it shows that the country is capable of conducting complex space missions.


India’s Chandrayaan-3’s rover is currently doing lot of scientific experiments in Moon’s South Pole region. The latest discoveries will benefit the global scientific community. Details at https://www.bbc.co.uk/news/world-asia-india-66654775


It is important to thank the women scientists who took India into space (from India’s Mars mission to Moon mission to Sun mission)

India’s space mission will inspire millions of students from all over the world (including students from economically poor backgrounds in the Global South) to STEM education and space science education.


>From humble beginnings in sheds (the equipments were carried in a bicycle and a bullock cart!) to landing on the Moon, to missions to Mars , India's space journey is an epic tale of ingenuity and resourcefulness.

This is the year of India’s G20 presidency.  Details at https://www.g20.org/en/   India’s idea of ‘One Earth, One Family, One Future’ is resonating across the world. This human-centric approach has been welcomed by all. India’s space mission is also based on this principle. India’s success belongs to all of humanity.


Best wishes
