This week, the Indian Space Research Organization (ISRO) is set to launch a very special mission – Aditya-L1, the nation’s first satellite dedicated to solar observation and research. Scheduled to be launched from India’s southernmost spaceport at Sriharikota, the mission is expected to provide valuable data that could help scientists better understand how the Sun works and how it affects the Earth’s atmosphere.
The Aditya-L1 mission involves a satellite placed in a halo orbit about one million km away from the Earth, in a special Lagrange point called L1. This orbit is beyond where the Sun’s rays are in equilibrium with that of the Earth’s gravitational pull. This makes it the ideal location for a solar observatory mission like Aditya-L1, which is aiming to capture an uninterrupted view of the Sun’s activities that will last a full year.
The satellite will be equipped with seven payloads, which include an imaging telescope that will capture images of the Sun in the visible light spectrum, a visible emission line coronal imaging system to study the Sun’s outer atmosphere, and an ultra-violet spectrometer to measure solar flares.
The data that the satellite will provide us help to understand the nature and causes of the solar corona and phenomena like solar storms, flares and prominences – events that can have huge impacts on our climate and technology. This data can be used to better predict and prepare for such events, ensuring the safety of our telecommunications systems and satellites, reducing power outages and protecting citizens from radiation.
The Aditya-L1 mission is part of a larger plan to make India a space power in its own right, and has been years in the making. Over the years, the scientists involved with the mission have worked hard to overcome the challenges that accompany space exploration – like testing the payloads in extreme conditions and developing sophisticated software to ensure the accuracy of the mission.
We’re now only days away from the launch of Aditya-L1 and all of us at ISRO are keeping our fingers crossed that the satellite will be able to make a successful journey to the L1 orbit and start sending valuable data back to the mission controllers. This mission is a testament to the hard work done by the team over the years, and will surely help India’s rise as a major player in the space technology field.
