The Aditya L1 spacecraft is India's first solar observatory and is expected to cost over ₹ 300 crores. This is about US$50 million.

The sun is currently in its 25th solar cycle, which began in December 2019 and will last until 2030. Solar cycles are periods of 11 years when the sun’s activity fluctuates between high and low.

In 2025, the eleventh year of the current cycle, the sun will reach its maximum activity.
