Introduction

Days after India’s successful moon mission, the country is now turning its attention towards the sun. The Indian Space Research Organization (ISRO) has announced that the Aditya-L1 spacecraft will be launched on September 2nd from the Sriharikota Spaceport. The primary objective of this mission is to study the sun and its impact on space weather.

Mission Details

The Aditya-L1 spacecraft, named after the sun in Hindi, will be placed in a halo orbit around Lagrangian point 1 of the Sun-Earth system. This strategic location will provide an unobstructed view of the sun. Lagrange points are areas in space where the gravitational forces of two large masses create stable positions for spacecraft. By utilizing these points, the spacecraft can conserve fuel and remain in position.

Advantages

This will be India’s first space-based observatory dedicated to studying the sun. It offers the major advantage of continuously observing the sun without any occultation or eclipses. This will allow scientists to gather valuable data on solar activities and phenomena.

Scientific Objectives

The mission aims to study the solar wind, which can have a significant impact on Earth. Solar wind disturbances have the potential to disrupt communication and navigation systems. By understanding these phenomena, scientists can develop better strategies for mitigating their effects.

Budget and Comparison

The Indian government allocated a budget of $46 million for this mission in 2019. However, there have been no updates regarding the current financial status. It is worth noting that India’s recent moon landing was achieved with a relatively low budget of $75 million. Other countries, such as NASA and the European Space Agency, have successfully launched missions to study the sun, including the Parker Solar Probe and the Solar Orbiter.
