India’s Sun Mission: Aditya-L1 Enters Final Orbit Today

After starting its lengthy voyage from ISRO’s Sriharikota launchpad more than four months ago, India’s first mission to study the sun, Aditya-L1 of the Indian Space Research Organisation, is scheduled to reach its ultimate target orbit on Saturday.

Constructed at an expense of ₹ 400 crore. The almost 1,500-kilogramme satellite is set to serve as the first space-based observatory in India. Studying the sun from a distance of around 1.5 million miles from Earth. At around 4 p.m., the satellite is anticipated to be launched into a halo orbit around Lagrange point 1 (L1). We selected the final insertion point because of its favorable location, enabling continuous Sun viewing and remaining unaffected by eclipses.

“This operation, which takes place on Saturday at about 4 p.m., will attach the Aditya-L1 to a halo orbit around L1. There’s a chance it will carry on traveling, maybe in the direction of the Sun, if we don’t take action, an ISRO representative told news agency PTI.

The space observatory will monitor the shifting space weather and alert scientists to any adverse events, such as solar storms and flares, that might interfere with satellite operations. Large-scale magnetic eruptions on the Sun that have the potential to affect the whole solar system are known as solar storms.

“Aditya-L1 can alert us to impending solar electromagnetic impacts on Earth and prevent disruptions. To our satellites and other power electrical and communications networks since it will be monitoring the Sun continually. This operation will link the Aditya-L1 to a halo orbit around L1. It is scheduled for this Saturday at around 4 p.m. If we don’t do something, there’s however a possibility it would continue to journey, possibly towards the Sun, an ISRO official told news agency PTI.

The space observatory will track the changing space weather and notify scientists of any unfavorable occurrences. That might disrupt satellite operations, such as solar storms, and flares. Solar storms are large-scale magnetic eruptions on the Sun that have the capacity to impact the whole solar system.

Along with carrying seven payloads, the Aditya-L1 satellite will use electromagnetic, particle, and magnetic field detectors. To carry out scientific studies aimed at improving our understanding of the photosphere. Chromosphere, and the outermost layers of the Sun, known as the corona. The satellite will get vital information regarding space weather dynamics, pre-flare and flare activity, and the less-studied solar weather.

Main scientific goals of the Aditya-L1; India’s Sun Mission

These are the main scientific goals of the Aditya-L1 mission, according to ISRO:

  • Examine the dynamics of the solar upper atmosphere (corona and chromosphere).
  • Examine the physics of the partly ionized plasma, flares, chromospheric and coronal heating, and the beginning of the coronal mass ejections.
  • Monitor the in-situ plasma and particle environment, indeed supplying information for the investigation of particle dynamics from the Sun.
  • Examine the solar corona’s physics and heating process.
  • Coronal and coronal loop plasma diagnostics: temperature, velocity, and density
  • The formation, motion, and source of CMEs (Coronal Mass Ejections)
  • Determine the chain of events that starts at the base, and extends into the extended corona. It ends at the chromosphere to cause solar eruptions.
  • Topology of magnetic fields and magnetic field observations in the solar corona
  • Space weather drivers: the genesis, composition, and behavior of solar wind
