ISRO Aditya L1 Mission Launch Date, Budget, Objectives, Payloads

The Indian Space and Research Organization (ISRO) is preparing to launch its latest spacecraft after the successful landing of Chandrayaan 3. We inform you that ISRO will launch the Aditya L1 mission which is the first solar mission by ISRO.

ISRO confirms the launch date of its highly anticipated solar mission – Aditya-L1 a few days after the soft landing of the Pragyan rover on the Moon’s south pole. According to the official tweet, ISRO will launch the PSLV-C57 vehicle for the Aditya L1 mission on September 2.

What is Aditya L1 Mission 2023-24

Aditya L1 will be India’s first space mission to study the sun. The spacecraft will be placed in a halo orbit around the Lagrange Point 1 (L1) of the Sun-Earth system, which is about 1.5 million km from Earth. A satellite in orbit around the corona around point L1 has the great advantage of watching the sun continuously without any occultation or eclipse.

This will provide an even greater advantage for monitoring solar activities and their impact on space weather in real time. The spacecraft carries seven payloads to monitor the photosphere, chromosphere, and outer layers of the Sun (the corona) using electromagnetic, particle, and magnetic field detectors.

Using the L1 special observation point, four payloads observe the Sun directly, and the remaining three payloads perform in situ studies of particles and fields at the L1 Lagrangian point, providing important scientific studies of the diffusive influence of solar dynamics in the interplanetary medium.

Aditya L1 payload suits are expected to provide the most critical information for understanding coronal heating problems, coronal mass emission, preflare and flare activities and their properties, space weather dynamics, particle scattering, fields, etc.

Science Objectives of the ISRO Aditya L1 Mission

The main science objectives of the Aditya-L1 mission are:

  • Study of the dynamics of the solar upper atmosphere (chromosphere and corona).
  • Study of coronal and chromosphere heating, partially ionized plasma physics, coronal mass ejection initiation, and flares.
  • Observing the particle and plasma environment in situ and providing data to study particle dynamics from the Sun.
  • Solar corona physics and its heating mechanism.
  • Diagnosis of coronal and coronal loop plasmas: temperature, velocity, and density.
  • The development, dynamics, and origin of CMEs – continuing medical education.
  • Determine the sequence of processes occurring in multiple layers (chromosphere, base, and coronal extension) that ultimately lead to solar flare events.
  • Magnetic field topology and magnetic field measurements in the solar corona.
  • Space weather drivers (origin, composition, and dynamics of the solar wind).

Aditya-L1 Payloads

The Aditya-L1 instruments are tuned to observe mainly the solar atmosphere, the chromosphere, and the corona. On-site devices will monitor the local environment at L1. There are seven payloads on board, four of which carry remote sun sensing and three of which carry on-site monitoring.
