Aditya-L1 India’s First Solar Mission Is Ready To Launch

The Indian Space Research Organization (ISRO) is all ready to start the next mission after the successful landing of Chandrayaan-3 on the lunar surface. India became the fourth country to landed on the moon and became the first country to landed on the south pole of the moon.

ISRO is going to launch Aditya-L1 Mission which is the India’s first Solar Mission. The spacecraft will lift off at 11:50 PM IST from the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh on 2nd September, 2023. The Aditya-L1 mission will be launched by ISRO’s PSLV XL rocket.

Aditya L1 is the first space-based Indian observatory to study the Sun. The spacecraft shall 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 the Earth. A satellite placed in the halo orbit around the L1 point has the major advantage of continuously viewing the Sun without any occultation/eclipses.

The Aditya L1 mission will take around 109 Earth days to reach at the halo orbit around the L1 point after the launch, which is around 1,500,000 km (930,000 miles) from Earth. The 1,500 kg (3,300 lbs). The spacecraft carries seven payloads to observe the photosphere, chromosphere and the outermost layers of the Sun (the corona) using electromagnetic and particle and magnetic field detectors.

ISRO Aditya-L1 Mission Launch Details:

Name of MissionAditya-L1
Spacecraft TypeSolar Spacecraft
Launch Date2nd September, 2023
Launch Time11:50 PM IST
Budget of Aditya-L1Approx. ₹ 400 Crores
Launch SiteSathish Dhawan Space Center, Sriharikota
Objective of Aditya-L1To Study the Gas Pattern, Coronal Heating & Solar Wind Acceleration

The estimated budget for Aditya L1 Mission is around ₹ 400 Crores as on September 2023. And this mission aims to study the Space Weather and Gases on Sun. The key objectives are solar wind acceleration, observation of photosphere, coronal heating, coronal magnetometry, solar energetic particles, observation of chromosphere and magnetic field of the Sun.

The Aditya-L1 mission aims to provide crucial insights into various aspects of solar activities and their influence on space weather. And understanding the reasons behind the formation and composition of solar wind and space weather, studying the dynamics of coronal mass ejections (CMEs), and observing the solar disk.

Objectives of Aditya-L1 Mission:

  1. Study of Solar upper atmospheric dynamics and the impact of the Sun’s radiation on the atmosphere of Earth.
  2. To observe the in-situ particle and plasma environment providing data for the study of particle dynamics from the Sun.
  3. To provide observations of Sun’s photosphere, chromosphere and corona.
  4. Observation of provide observations of Sun’s photosphere, chromosphere and corona.
  5. Physics of solar corona and its heating mechanism.
  6. Identify the sequence of processes that occur at multiple layers.
  7. To provide crucial insights into various aspects of solar activities and their influence on the weather of space.
  8. Observation of unprecedented insights into the Sun’s behavior and its impact on space weather.
