The Proba-3 mission is a joint project of many European countries. These include Spain, Poland, Belgium, Italy and Switzerland. This mission with an estimated cost of 200 million euros will last for two years. This will be a historic mission under which ‘precision formation flying’ will be tried for the first time in space ISRO is going to do a historic launch. Why is it important? On the evening of 4 December 2024, it will launch the European Space Agency’s Probe 3 satellite from its PSLV Excel. The main objective of this satellite launch is to study the corona of the sun and demonstrate the new technology of launching multiple satellites simultaneously. This satellite will study the atmosphere around the sun, which is a very large layer. The satellite will help in understanding it.

Will the mysteries of the sun be revealed?

ISRO is going to launch a new mission that will create an artificial solar eclipse. The name of this mission is Probe 3. However, this is not a mission of the Indian Space Agency but of the European Space Agency. It will be launched on December 4 from Sriharikota through ISRO’s PSLV rocket. The interesting thing is that not one but two satellites will be launched simultaneously. These twin satellites will orbit together. Let us understand this difficult topic related to space, Probe 3, in some simple words. Probe means Project for On-Board Autonomy. In Latin language, it means let’s try. Before this, ISRO had also launched Probe One and Probe Two missions. For the Probe 3 mission, scientists from Spain, Belgium, Poland, Italy, and Switzerland have worked together. Now let us understand what the objective of the Probe 3 missionThe temperature of the Sun’s surface is around 5500 degrees Celsius.

The big secret is that the outermost layer of the Sun’s outer atmosphere, which is called the corona, is much hotter than the seven. The temperature here is about 20 lakh degrees Celsius. It is said about the corona that due to this, the Sun’s surface temperature is about 5500 degrees Celsius. The solar wind coming out affects the satellite and the earth, but this corona is very durable to see. It is visible only when the sunlight is obstructed. This often happens during a solar eclipse. Then this corona of the sun is visible to humans from the Earth, but this is possible only when there is a total solar eclipse and this total solar eclipse occurs once in many years, and that too for just a few minutes. Now this Probe 3 mission is going to study this corona of the sun by creating a situation of solar eclipse. This will be done 50 times a year and each round will be 6 hours long. Through this, scientists will be able to study a part of the sun that is not easily visible, and not much is known about it yet. How will the satellite work? The thing that makes this mission different from other space missions is that it will have not one but two satellites. This is the world’s first precision formation flying mission. Formation flying means flying in a formation as is done for any other show or like a flock of birds flies in a formation. For this mission, new technology, algorithms, software, and sensors have been created for the satellite. So what will change if there are two satellites instead of one? These two satellites will go in space in a development for example in a fixed position with each other all the time. By doing this, both these satellites will work in coordination in this space mission. One of these twin satellites will have a coronagraph and the other will have a different color which will hide the sun’s glow. One of these satellites will cover the sun and create an artificial solar eclipse while the other satellite will observe the sun. This satellite will study the structure of the corona, the explosion of plasma from the surface of the sun, and the gas waves visible from the corona, the corona injection. The study of these things is necessary to know why the corona is so hot. All these studies will be useful in understanding the conditions created in space by space weather and sun rays. The Probe 3 mission will operate for the next 2 years.

PROBA-3 Mission: ISRO again hoisted the tricolor, successful launch of European Space Agency’s satellite

After postponing the launch of PROBA-3 on 4 December 2024, ISRO launched it today i.e. on 5 December 2024 at 4:04 pm. The launch was done from launch pad one of Satish Dhawan Space Center in Sriharikota with PSLV-XL rocket. After a flight of just 26 minutes, ISRO’s rocket will put the satellites in space. In this mission, ISRO is flying the PSLV-C59 rocket. In this, C59 is actually the rocket code. This was the 61st flight of PSLV and the 26th flight of the XL variant. This rocket is 145.99 feet high. This four-stage rocket weighs 320 tons at send off. This rocket will put the PROBA-3 satellite in an elliptical orbit of 600 X 60,530 km.

ISRO launched Prabhat-3 mission, this satellite will study the sun
ISRO has launched Prabhat 3 mission today. This launch will take place from Satish Dhawan Space Center in Sriharikota at 4:04. After a flight of only 26 minutes, ISRO’s rocket will put the satellite in space. It is a precision formation flying satellite, which means there will be not one but two satellites whose total weight is 550 kg. Both these satellites will study the sun’s corona while orbiting the earth together in a line. The distance between the two satellites is 150 meters. Because of this satellite, scientists will be able to study space weather and solar winds so that it can be known what is the dynamic of the sun and what effect does it have on our earth.
