Before India’s first Sun mission, “Havans” were undertaken in preparation for the Aditya L1 launch.

People in Varanasi performed “havans” while holding images of the Aditya-L1 launch vehicle in celebration of the nation’s first successful launch of a solar mission. On Saturday morning, hours before India’s first Sun mission, Aditya L1, was slated to launch from Sriharikota in Andhra Pradesh at 11.50am, prayers and havans were conducted all throughout the nation. The Polar Satellite Launch Vehicle (PSLV)-C57 rocket will take out from the Satish Dhawan Space Center’s launchpad.

In Uttar Pradesh’s Varanasi, people performed “havans” holding pictures of the Aditya-L1 launch vehicle and offering prayers for the successful launch of the country’s maiden solar mission.

A group of locals are seen carrying Indian flags and posters that read “new sun mission by ISRO” in a video released by the news agency PTI. S Somnath, the head of the Indian Space Research Organization (ISRO), conducted prayers earlier on Friday at the Chengalamma Parameshwari Temple in the Tirupati district.

A group of ISRO scientists also went to Tirumala Sri Venkateswara Temple to pray while carrying a model of the Aditya-L1 Mission.

The goals of Aditya-L1

India’s first-ever voyage to study the characteristics of the Sun is Aditya-L1, which was created with this objective in mind. The satellite will travel 125 days to the unique location known as L1 (Lagrangian Point) after being launched. At this moment, the satellite will be able to continuously watch the Sun without interference from eclipses or occultations. Because anything positioned in L1 will remain comparatively stable in relation to the Earth-Sun system, it is particularly interesting.

The primary goals of India’s solar mission are to understand the physics of the solar corona and its heating mechanism, the acceleration of the solar wind, the coupling and dynamics of the solar atmosphere, the distribution of the solar wind, temperature anisotropy, the origin of CMEs and flares, and the near-Earth space weather.

Ahead-of-time alerts about solar winds, which can move at up to 600 km/s, are also available from Aditya-L1. Before the winds reach Earth, the satellite can measure them and send out alerts.

Seven distinct payloads are installed on the spacecraft to investigate the Sun. The Sun’s light will be observed by four of these instruments, while magnetic fields and plasma will be closely examined by three others.

Once it reaches its target orbit, the main payload, the Visible Emission Line Coronagraph (VELC), is scheduled to relay 1,440 photos per day to the ground station for study. The strong light from the Sun’s surface can be blocked out by VELC, letting us to continually study the much fainter corona. When there is a total solar eclipse, we can see the corona.
