It is a satellite dedicated to the complete study of the sun. According to the ISRO. It has 7 different payloads devoted all developed indigenously. The meaning in Sanskrit is the Sun and L1 refers to Lagrange point 1 of the Sun-Earth system.

India has taken a significant step towards completing its Solar mission with the successful launch of Aditya L1 The spacecraft was launched from Sriharikota on Saturday and is set to be placed in its Halo orbit, L1, near the Sun in just four months. Once in position, Aditya L1's seven payloads will be activated to explore and uncover answers to some of the most fascinating mysteries surrounding the Sun. This mission marks an exciting milestone in India's space exploration efforts.

One such question is about the extreme temperature of the Sun's corona. It is the outermost part of the Sun's atmosphere a is usually hidden by the bright light of the Sun's surface.

To understand the primary goals that why the Sun's corona is astonishingly hot, reaching temperatures of up to 2 million degrees, in stark contrast to the relatively cooler surface of the Sun at around 5,000 degrees.

To overcome the frequent obstruction of the Sun's view caused by Earth's orbit, the objective is to achieve a continuous observation of the Sun for 24 hours a day. This would require a unique approach to space exploration that enables a constant, uninterrupted view of the Sun, which is not currently possible from Earth's standpoint.

Additionally, this mission is increasing India's ability to observe the Sun for 24 hours a day. The unhindered observation of the Sun will help in closely monitoring its activity.

Key instruments of the spacecraft are SUIT, VELC, and five more

SUIT (Ultraviolet Imaging Telescope), is an ultraviolet imager that captures continuous images of the Sun. The ultraviolet spectrum is important for making observations. The reason for its importance is the large amount of ultraviolet and X-ray radiation emitted from the Sun's corona.

Another major instrument is VELC. It is a spectrograph that focuses on the Sun's corona—the outermost layer of the Sun's atmosphere. Notably, it extends far beyond the Sun's visible disk. VELC will also monitor the corona alongside SUIT and will let the ISRO scientists correlate changes in the Sun's corona with events on the Sun's surface.

Aditya L1 is a mission aimed at uncovering the mysteries of the Sun's activity.

Have you ever wondered why the Sun's corona is so hot? Well, it's a mind-boggling mystery that has left solar scientists scratching their heads for years. The temperature of the Corona car soared up to a whopping 2 million degrees, which is in stark contrast to the Sun's relatively cooler surface at around 5,000 degrees. Don't worry, the Indian Space Research Organization (ISRO) has a plan to unravel this mystery with their new satellite, Aditya L1.

The Aditya L1 satellite is a game-changer for India, as it will help scientists establish the link between the Sun and its corona. By studying high-energy phenomena, such as solar storms, Aditya L1 will provide insights into the causes of this temperature difference. The satellite will also help in bridging the connection between the Sun's surface and the emission of high-energy particles during solar storms.

It's important to understand the connection between the Sun and its corona because these solar storms can cause serious damage to human technologies, including satellites and communication systems. According to Somak, a solar scientist, these storms are closely related to the Sun's magnetic activity. He warns that we need to be prepared for the potential damage caused by these storms and that Aditya L1 will play a crucial role in this preparation.
