India's Aditya L1 mission will solve the mystery of the Sun's invisible rays and energy released from solar eruptions. According to ISRO, Sun is the nearest star to us, it can help us the most in the study of stars. The information obtained from this will help in understanding other stars, our galaxy and many secrets and laws of astronomy.
The Sun is about 150 million km away from our Earth, although Aditya L1 is covering only one percent of this distance, but even after covering such a distance, it will give us many such information about the Sun, which can be known from the Earth. Would not have been possible. It is not physically possible to send a mission to the Sun which has a temperature of 15 million degrees in its central region and 5,500 degree Celsius on the surface. Due to the extreme temperature, there is continuous nuclear fusion (lighter nuclei joining together to form nuclei of heavier elements). This reaches our earth in the form of light and energy. India's first Sun mission is being launched with the main goal of observing this corona of the Sun. This campaign has been kept in the space based observation category.
Security of satellites and astronauts
Sun is a very active star, there are frequent explosions in it, sometimes excessive energy is also released. These are called coronal mass ejections (CMEs). A large amount of these also reach our earth, due to which the magnetic field of the earth is affected. Hundreds of our satellites can be harmed by them. If we have a satellite that can inform about these dangers in advance, then any major loss can be avoided in future. Similarly, India will have its own system to protect astronauts from being hit by them.
seven equipment will be required
- Visible Emission Line Coronagraph (VELC): Built by the Indian Institute of Astrophysics (Bangalore). It will study the changes in the Sun's corona and emissions.
- Solar Ultra-Violet Imaging Telescope (SUIT): Developed by the Inter-University Center for Astronomy and Astrophysics (Pune). It will take pictures of the Sun's photosphere and chromosphere. These would be pictures in the near-ultraviolet range, this light is almost invisible.
- SOLEX and HEL1OS: The Solar Low-energy X-ray Spectrometer (SOLEX) and the High-energy L1 Orbiting X-ray Spectrometer (HEL1OS) were built by the UR Rao Satellite Center in Bangalore. His work is the study of Sun X-rays.
- Aspex and Papa: The Aditya Solar Wind Particle Experiment (Aspex) by the Physical Research Laboratory (Ahmedabad) and the Space Physics Laboratory Vikram Sarabhai Space Center (Thiruvananthapuram) have built the Plasma Analyzer Package for Aditya (Papa). Their job is to study the solar wind and understand the distribution of energy.
- Magnetometer (Mag): Made by Electro Optics Systems Laboratory (Bangalore). It will measure the interplanetary magnetic field around L1 orbit.
