You know the sun. The sun is the mode that provides sunlight for us. If there is no sun, we have no differentiation of the daytime and nighttime. In other than that, you know if there is no sun, the process photosynthesis also not taken place correctly. In that situation, something can occur in the wrong way in the food chains too. Sometimes there may be deterioration of the food products can occur. Now you know how this sun is essential for us.
Then I have a question. Would you like to investigate the sun? I know your answer. That may be, I would like to study the sun, but it is too hot then how can I reach towards the sun. Once I reach nearest to the sun, I will melt with the heat. My answer is even like that. But there is a solution to this question. This is not my answer. This is NASA’s answer. Now we will see it.
NASA ‘s solution for the question
When I am saying only NASA, you can think about what is their solution because NASA is famous in the spacecraft field. Their answer is the parker probe. The mission of the parker probe is to research about the sun. How that this probe will reach to the sun? Now your curiosity was aroused. Keep calm. You can see how. But before that, I have to tell you about some small description about our sun. I said our sun because that is the sum that belongs to our solar system. Now see the unknown details about the sun.
Actually, the sun is a star that included in our solar system. The mass of the sun is 330,000 times the mass of the earth. The diameter of the sun is about 1.39 million kilometers. In other words, it is about 109 as the earth’s diameter. The main constituents of the sun are hydrogen and helium. Oxygen, carbon, and Neon are the other minor elements. About 75% of its atmosphere consists of the nitrogen, while 23% of its atmosphere consists of the helium — this massive star in a spherical shape. Sun is classified as a G type star as well as that this is called a yellow dwarf. The center part of the sun is too hot.
Sun is doing very significant purposes. In one second, the sun has the ability to convert 4 million of matter to energy. How is fast is the sun? As well as that sun is a luxurious element star. This is the brightest object that can be seen in the sky. The light is traveling to the earth horizon in 8 minutes and 19 minutes from the sun horizon. It takes two minutes less if the sun’s point is closer to the earth.
This is a speedy rotating object. The energy that is stored within the sun is emitting as the sunlight. The compounds that the sun is containing are inherited when this star is formed in the interstellar medium — the heat transfers to the outer space from the sun by the radiation method. The primary process inside the sun is developed with hydrogen and helium. After some time, helium gas can accumulate in the inner core of the sun. First of all, scientists thought that the composition inside the sun is the same as the composition in the atmosphere. But finally, it had proved.
I gave more essential details about the sun. To find more information, the parker probe had designed. Now it is time to see about the parker probe.
Space probe to the sun – parker probe
You know that I am starting about the parker probe. This is a robotic spacecraft by NASA. The primary function of this spacecraft is to investigate the outer corona of the sun. This probe launched in 2018. This probe travels at the speed of 690,000km per hour. This robotic probe was named as various names in the past. They are a solar probe and solar probe plus. This called the parker in 2017. Parker is the living scientist of NASA. And now then it was named as the parker probe. This parker probe launched on the 12th of August 2018 from the Cape Canaveral SLC 37.
You know that only a space probe just essential to this mission. There are needed some other devices too. Therefore there are some other devices here in this space probe. They are as follows.
SWEAP – solar wind electron alphas and protons investigation.
This can count protons and heavy ions. As well as that through this component, it can be measured the physical properties such as speed and velocity. There are a solar probe analyzer and a solar probe cup.
SPAN – solar probe analyzers
WISPR – wide-field imager for the solar probe.
This is a telescope that can take photographs of the corona.
FIELDS – electromagnetic fields investigation
This is used to take measures of the electric and magnetic field, electron temperature, and the radio waves. Here there are magnetometers as well as that there are plasma voltage temperatures.
SPC – solar probe cup
ISIS – integrated science investigation
of the sun energetic Particle instrument
This is used to measure protons and heavy ions. There are two energetic instruments in this device.
On the 29th of October, this probe closest to the sun. This is the first man-made object that reaches close to the sun. In other than that this will be the first space probe that reached to the corona of the sun. This project decided in 2009. At that time, the cost estimated at US$1.5. This parker probe made to uses multiple venus gravity assists for a more direct flight path. They can be powered by solar panels.
Now, do you have any questions about this solar probe? I have a question. It is that when entering the sun’s atmosphere, how would be avoiding the sun’s heat. It will melt if this solar probe exposed to the heat. But it is prevented through the solar shield. The exposure to solar radiation is prevented through this cover. This is very needed because it will investigate the structure and dynamics of the sun’s coronal plasma and the magnetic field. Therefore this space probe designed with the carbon-reinforced carbon composite material that can overcome to a high temperature. As well as there is a reflective alumina surface to avoid the absorption of the solar rays. The important scientific instruments are in the shield. As I told above, power is supplied through solar panels. There are two solar panels.
This space probe launched on a Delta IV Heavy launch vehicle, and the upper stage is based on the STAR 48BV. It is a solid rocket motor. When this space probe reaches near to the sun, it will reach the speed of 200km per second. I told above the goals of this mission above mainly there are three. They are as to study the trace of the energy flow of the corona, to study the magnetic field within the sun and the mechanics in the transportation of the energetic Particles. Q
I think you don’t know the reason why I selected this as my topic. It is because some details of this probe have released recently on the 12th of November 2019, some information through this space probe released to the public. On the 19th of January 2019, this space probe reached near to the sun. On the 9th of September 2018, this probe started the activation of the instruments than on the 3rd of October 2018 it finished seven flybys to the venus as planned.
Now we have reached the end of this article. I think some more details will report about this space probe in the future.
