India has launched its first observation mission to the Sun, just days after the country made history by becoming the first to land near the Moon's south pole.
Aditya-L1 lifted off from the launch pad at Sriharikota on Saturday at 11:50 India time (06:20 GMT).
It will travel 1.5 million km (932,000 miles) from the Earth - 1% of the Earth-Sun distance.
India's space agency says it will take four months to travel that far.
India's first space-based mission to study the solar system's biggest object is named after Surya - the Hindu god of Sun who is also known as Aditya.
Once Aditya-L1 reaches this "parking spot", it would be able to orbit the Sun at the same rate as the Earth. This also means the satellite will require very little fuel to operate.
Isro has not said how much the mission would cost, but reports in the Indian press put it at 3.78bn rupees ($46m; £36m).
India has more than 50 satellites in space and they provide many crucial services to the country, including communication links, data on weather, and help predict pest infestations, droughts and impending disasters.
If Aditya-L1 is successful, India will join the select group of countries that are already studying the Sun.
Japan was the first to launch a mission in 1981 to study solar flares and the US space agency Nasa and European Space Agency (ESA) have been watching the Sun since the 1990s.
In February 2020, Nasa and ESA jointly launched a Solar Orbiter that is studying the Sun from close quarters and gathering data that, scientists say, will help understand what drives its dynamic behaviour.
And in 2021, Nasa's newest spacecraft Parker Solar Probe made history by becoming the first to fly through corona, the outer atmosphere of the Sun.
Aditya-L1 will carry out scientific studies of the Sun from a vantage point 1.5 million km above Earth.
