What Is Aditya L1?

Aditya L1, an ambitious endeavor by the Indian Space Research Organization (ISRO), aims to send a spacecraft on a mission like no other – a mission to study the Sun up close and personal. As the first space-based Indian mission dedicated to solar observation, Aditya L1 holds the potential to revolutionize our understanding of the Sun’s behavior and its impact on space weather.

ISRO Aditya L1 Mission Budget

  • The Indian Space Research Organization (ISRO) has achieved significant milestones in various space missions, including the recent success of Chandrayaan 3.
  • ISRO’s next venture, the Aditya L1 mission, is set to launch on September 2, 2023, focusing on solar exploration.
  • The mission aims to study gas patterns, coronal heating, and solar wind acceleration, providing crucial insights into the Sun’s behavior.
  • You should know that ISRO Aditya L1 Mission Budget is Rs 400 Crore,
  • ISRO initiated work on the Aditya L1 mission in December 2019, showcasing meticulous planning and dedication.
  • The spacecraft is poised for launch, and the Aditya L1 Launch Event will be broadcast live on the ISRO Youtube Channel.
  • Observing the live launch on September 2, 2023, is a moment to take pride in India’s accomplished scientists and their contributions to space exploration.

Halo Orbit around Lagrange Point 1 (L1)

Unlike conventional orbits, Aditya L1 will take a different approach by positioning its spacecraft in a halo orbit around Lagrange Point 1 (L1) of the Sun-Earth system. This strategic location, approximately 1.5 million kilometers away from Earth, offers a distinct advantage – continuous visibility of the Sun without any interruptions caused by eclipses or occultations.

Advantage of a Halo Orbit

The halo orbit provides an unprecedented vantage point, allowing Aditya L1 to observe the Sun around the clock. This uninterrupted view is a game-changer, enabling scientists to monitor solar activities and their effects on space weather in real-time. This unique perspective opens doors to understanding solar dynamics and their propagatory effects on the interplanetary medium.

Aditya L1 Payload Details

Equipped with a suite of seven cutting-edge payloads, Aditya L1 aims to explore various layers of the Sun, from the photosphere to the outermost corona. These payloads include both remote sensing instruments and in-situ observation tools. Four of these payloads will directly observe the Sun, while the remaining three will study particles and fields in the L1 Lagrange point’s vicinity.

The heart of the Aditya L1 mission lies in its payload collection, each designed with specific scientific goals in mind:

Aditya L1 Payload NamePurpose
Visible Emission Line Coronagraph (VELC)Imaging and spectroscopy of the solar corona.
Solar Ultraviolet Imaging Telescope (SUIT)Capturing images of the photosphere and chromosphere using narrow and broadband observations.
