India's first solar mission 'Aditya L-1' will be launched this month, preparations begin in full swing

Image: Twitter



India's first solar mission Aditya L-1 is going to be launched in June-July. This mission will send a spacecraft to study the Sun. ISRO chief Dr. S. Somnath made this announcement recently. Another important thing in the current information is that the payload visible line emission coronagraph for the spacecraft was given to ISRO. The payload is prepared by the Indian Institute of Astrophysics. VELC is the most important and primary payload of this spacecraft. VELC has taken more than 15 years to build. It is therefore considered a very complex payload.

How was this mission named?
India's Suryayan mission has a total of 7 payloads. Of which six payloads have been prepared by ISRO and one by other organizations. The spacecraft will be placed in orbit at L1 i.e. Lagrange point 1 between Earth and Sun. For this Suryaan mission is named 'Aditya L-1'.

Where will this spacecraft be positioned?
 There is a parking lot at Lagrange Point A Space. Where many satellites have been parked. India's Sunyaan will be stationed at this point, about 15 lakh kilometers from Earth. From this place he will study the Sun.

Correct examination of VELC payload after loading
 Soon the VELC and other payloads will be set aboard the Aditya-L1 spacecraft at the UR Rao Satellite Center in Bengaluru. They will then be loaded into the PSLV rocket and taken to the launch pads. The principal investigator of the VELC payload said that the scientific camera installed in this payload will provide us with very good resolution images from the Sun.

Why study of Sun is necessary

  • Every planet and outside the solar system, including Earth, is growing in number of exoplanets, and this growth is controlled by the host star. Solar weather and atmosphere, determined by the processes occurring in and around the Sun, affect the entire Solar System.
  • Studying the Sun becomes important because continuous solar observations are needed to learn about and track storms on Earth and predict their effects.

How many solar missions have been sent so far?
 So far, a total of 22 Suryayan missions have been sent by countries like America, Germany, European Space Agency. NASA has sent the most solar missions. Pioneer-5 mission was first sent by NASA.

Now contactless fingerprint system for Aadhaar

Image
Currently, when we want to unlock the smartphone, depending on the model of the phone, we have to touch the power button on the back of the phone or on the screen on the front or elsewhere with our thumb or other finger. Similarly, when we want to prove our identity with the help of Aadhaar system in various places, we have to put our thumb or other finger on a small device connected by wire to the phone or computer. Touch has so far been important in the use of fingerprints. But now the exercise of removing touch from the whole thing has begun. The Unique Identification Authority of India, which administers the Aadhaar system in India, and the Indian Institute of Technology , Bombay, have jointly started an effort to develop a contactless fingerprint biometric capture system (a lot of work has been done in this direction in other countries as well). This system will capture fingerprints of multiple fingers for greater accuracy. In the long run, this technology will be added to com...
