NASA, that is it. There is no word or description to tell you about NASA. Because we all know about NASA. Even small children know. But they didn’t know the task of NASA. But they know the name. I have to tell you that NASA is an organization that works to form interconnection with the earth to the planets other than in space. The most powerful technologies are used in NASA. An example of robotic technology. Those technologies cannot be equivalent to anything. That’s an important thing. Today we aren’t here to talk about the technologies. We had to talk mainly about the Juno spacecraft. As well to find the recent news about that.
Recently Juno went closer to the above planet. Plus, it captured an important image. The above image is the turning point of the investigations about the space. There is something included in the above photograph. There are many clouds. All the clouds are swirling around the whole sky. Those clouds are usually within the magnetic north. Have you an idea about the exact place that the image captured??. The image includes the North temperate belt. That image is by the Juno spacecraft. There are specific features of clouds. They consist of elements areas, white pop up clouds, anticyclonic clouds. There is a specific name for that. The specific name is the white oval.
The image captured recently. That is during the 29th of October 2018. The space probe Juno reached Jupiter for the 16th time. Can you guess what part of Juno that used to take photographs?? Don’t you understand that?? Then I’ll mention to you about that. The specific part is that the Juno cam. We would see that through the following details. Here I am to give you some knowledge about the Jupiter, Juno cam in other than that details of the north temperate belt. Did you wish to know it? Surely. Now, this situation is to see more details of planet Jupiter. Read the following.
Planet Jupiter and JUNO
You know something about the above natural object. This is the largest planet in our solar system. And in our milky way galaxy. This is red in color. It’s surface color. Why is that exist in red color? Can you think of the reason for that? The reason is the large red spot on the surface of Jupiter. The above planet placed as the fifth place as its respective order. The space from the sun to the planet Jupiter is about 778.5 million. Except then that feature, the estimated mass is about 1.898 ×1027 kg. Plus that the surface area of the above planet is 61.42 billion square km.
What do you know about the name of the above planet??? The name is a bit unfamiliar. Isn’t it??? Why is that? What is your idea about the name? That is a very simple name. The Jupiter signifies the character of a god. Jupiter is a Roman god. This planet is named because of that above god.
Other than the largest natural object, this is one of the brightest natural objects in the sky. This is a had placed as the fourth. That is after natural objects such as the sun, moon, and Jupiter. Mainly atmosphere of Jupiter consists of helium and hydrogen. They are the main constituents.
The above is a speedy rotating planet. The planetary ring system and powerful magnetosphere are the important systems include within the above planet. There are 79 known moons are in Jupiter. We all know our earth has only one satellite. Among those 79 moons, there are Galilean moons include to this list. There are about four of them. Pioneer, voyager flyby, and the Galileo orbiter are some of the spacecraft that are launched to investigate the above Jupiter.
The last time, the new horizon entered the atmosphere of the above planet. You know the very recent investigation. Those are the provings of having the water vapor on the surface of Europa. Europa is a satellite of Jupiter. Even though it is one of the moons out of the known 70 moons, these above details are the basic facts about the planet Jupiter. There is another important fact that I wanted to discuss with you. It is the large red spot on the surface of Jupiter. I have to tell you about that feature. If not, it will make a great blank.
The large red spot of Jupiter
You know that Jupiter is also known as the red planet. And now you know the reason for it. That is because of the giant red spot. Actually, this is not a spot. This is an anticyclonic storm. It is even larger than our planet Earth. Scientists have told that this started from the 1665 – 1831 time period.
The large red spot can be seen with an earth-based telescope. Through those, there can be seen two dark red spots next to the dark red spots. Scientists said that this is a permanent feature for this planet. But since the day this had discovered, that spot seems to be decreasing. Between the years 1995-2000 through a NASA infrared telescope facility, the scientists had found the spot is changing its size and shape within a short period of time.
Through the space voyager, it can be seen the atmosphere rotates differently than the red spot. Sometimes the red spot rotates faster and then slower. Now you know more details about the Jupiter as well as the Great red spot. Then we have to see about the founder of the specific photograph. Or an amazing photographer.
This is a special spacecraft that planned to orbit around the planet Jupiter. What is such a specialty on that planet??? In the above, I told you about that specialty. The operation partner is the NASA organization. The designer is also a famous one. That is Lockheed Martin. As you know, this launched into space from our familiar state. That is Cape Canaveral. That was on the 5th of August 2011.
This above mission is a part of the new frontiers program. Then on the 5th of July 2016, Juno entered the polar orbit. After entering the orbit, it can start the investigation easily. Finalizing its specific task again, it will come back from the orbit of the Jupiter. Jupiter orbiter is the mission type of the Juno spacecraft. The journey or the investigation planned for about seven years.
The initial mass of the Juno is about 3625 kg. There are lithium power batteries that were included in the spacecraft. United launch alliance is the contractor of the above mission. Single spacecraft cannot perform such a task. There are some other instruments even need for that. For that, there are some instruments. We will see them later. Now we will move to the basic details of the Juno.
The Juno is…
Do you know the main mission by the Juno? It had determined to find out some physical characteristics of Jupiter planet. What are those?? They are the gravity of Jupiter, the magnetic field of Jupiter, and the other physical characteristics. Other than the above, it will investigate the planet formation even. Through that, scientists would be able to find out the materials included on the planet, how that formed, water presence of the planet, and about the storms that occur on the planet.
Guess something. Is Juno the only spacecraft that went to the Jupiter?? Actually, it is not. That is, the second spacecraft went to Jupiter. That is after the Galileo orbiter. That remained in the Jupiter orbit upto 2003. There is another specialty in the Juno. Usually, spacecraft are powered by fuel. That is not according to the Juno because there are solar panels for that purpose. Through the solar panels, the essential energy produced by solar power, or sunlight. There are three solar power panels contain in the Juno.
Then we will see about the name. This is not familiar. The name Juno came from the Greek language. Many stars are even named from the terms in the Greek language. Jupiter is also the name of the Roman god. There is another name for the Juno probe. That is the new frontier 2. That is because this mission is under the main Mission of the new frontier. 2 is for the second probe to the planet Jupiter. The naming even has a significance itself.
Can you imagine the distance traveled by the Juno?? Approximately it is about 2.8 billion kilometers. We can think about it and get an idea of about 2.8 km. But that is a million km. The initial plan was to orbit Juno about 37 times around Jupiter. That was released through the Atlas V. Already. You know the site. Atlas V, along with with an RD 180 main engine. That engine has to power with kerosene. Or else liquid oxygen has to use for the power-up engine.
There is another important point that has to talk with you. That is the expense. Especially in these types of projects, the high expense has to be maintained. The estimated cost is about US$ 700 million. That is for the launch in 2009. For the launch of 2011, it was changed. That came up to US$1.13 billion.
The main scientific goals that it achieved are as follows.
- The existing ratio between the hydrogen and oxygen gas
- To find the approximate mass of Jupiter.
- Formation and the structure of the magnetic field of Jupiter.
- We are finding the three-dimensional picture of Jupiter’s Auroras.
- Investigation about the angular momentum of the Jupiter.
In the above, I told you that I am giving you some details of the Juno payloads. That time is now.
Payloads of the Jupiter
The microwave radiometer is a scientific payload. This above instrument will help to find out about the electromagnetic waves. And it will measure the percentage of water inside the planet. The jovian infrared auroral mapper is even another instrument. That will help Juno probe to provide the images of the Auroras. The magnetometer is the next one. This above will detect the strength and power of the magnetic field. Ultraviolet Spectrograph is a recorder for the wavelengths. Other than in the above radio and plasma wave sensor, jovian auroral distribution experiment, and gravity science are some payloads of the Juno probe.
Then I told you the most important details about the Juno. Until now, it is performing its tasks. It will end research in 2021. It will find more and more such important details. Then this is the end of this article. I think the above details will be useful for you.
