Hope you know Neil Armstrong The first man to step on the moon But you don't know Eugene Semnan and Harrison Schmitt. I am 90% sure about this They are also very famous. These two people were stepping on the moon But when they set foot on the moon in December 1972, From that time until now they were the last people to go to the moon Since 1972, no man has gone to the moon
Very surprising! Maybe last was the Apollo 17 mission. Exadata Hossain also went to that mission And when he came out of the moon he looked at the earth and gave a salute Due to which the fate of Virat Kohli and all the people of the world are intertwined Virat Kohli century or not, But it is very likely that the curse of not being able to go to the moon is going to be broken very soon Because more than 50 years later, NASA is still with the passion of its 70s They have launched a mega series of missions called Artemis Under which people are going to set foot on the moon again by 2025 And interestingly, its first mission was Artemis 1 Just launched today, very happy news What else is in this program? Why is it so different and unique? What are the major challenges we have to face in this program? And spending so much money to send people to the moon, what is our profit? I will discuss this whole matter in today's blog So let's get started! Our Chou khan t-shirt is coming Available to buy from Mad Coffee In the Link Description box First of all, I hope you understand Artemis, the program is the first since 1972 to send a man to the moon Already for this it is a unique program Apart from this there are many other reasons You look at the Apollo Mission Every astronaut is either male or female. This is likely to be the first time a woman has been in space And any black or brown colored people Going to step on the moon, which could be a historic moment This is the first time that a government agency like NASA on such a large scale, Collaborating with many organizations, private or commercial Supposedly, Jeff Bezos' Blue Origin or With private companies like Elon Musk's SpaceX or Boeing USA government agency NASA is working together Generally, government agencies do not want to work with these private organizations They tend to be a bit nosy In many cases, they do not want to be accused of corruption Just think, if Dhaka WASA started working together with Aquafina and Kinley today So people can start swearing a lot I'm not saying, don't abuse now Thing No. 3: When Last sent Apollo 17 to the Moon in 1972, There they were on the surface of the moon for only 3 days Now in this new Artemis program, plans are being made, Can they be kept in a base on the moon for weeks or even months? Such planning is underway, which is a very challenging task You will understand soon
4 things below are very important
Where are you going this time? At the Moon's South Pole, Where no man has gone before in the Apollo missions The South Pole of the Moon is a very interesting place Number 1 reason, there is no sunlight at all This place has not seen sunlight for billions of years Because of this, Permanent Shadow That is, the moon's craters that have been in the shadow for a long time, It is estimated that there is a possibility of getting up to 100 million tons of water there. And getting water in that place means, This will be a very important event in the history of human civilization Getting water outside of Earth is a pretty cool thing The possibility of life being there increases even more Besides this, since there is no sunlight in that place, Where did our solar system originate from? An undisturbed sample of it is possible from here, Which are other places on the moon, where sunlight may have fallen, There are spoiled samples in that place, so they are of no use to us. Maybe this time Thing number 3, the surface of the moon has a layer of soil, This is what we call Regolith This layer is very light, very loose soil But it is assumed, here Hydrogen, Ammonia, Methane, Sodium Even so many natural resources like silver can be found Which will actually benefit America
We will not benefit
They can bring minerals from the moon and sell them on Earth Then maybe China and Russia can start bargaining. We also want a share of it You may see some new fights in the future. It would be great if they dropped nuclear bombs on the moon I joked! Actually I don't mean This time let's talk a little inside The Artemis program will use a rocket called the Space Launch System or SLS. See, when a rocket carries something into space, The heavier the item, the more difficult it is for him to carry it to the space. Now here you want to send people with rockets, This is much more difficult for him to carry. This is why your rocket has to be very powerful Space has all its useful equipment, including humans. To take them together That being said, the rocket in the Artemis program, the SLS, This will be the world's most powerful rocket ever. Because they are a spacecraft, called Orion…Up to 4 astronauts And can also carry a cargo in a single mission which is strange in power, extraordinary, Never before in the history of human civilization, A rocket is going to space with so much cargo But there are problems! Once you send the rocket, it's over. You cannot use it again, it is not reusable. Number 2 thing, it costs a lot of money. Not so cheap. Each launch will cost you $876 million to $2 billion Once you launch But what are the benefits? The rocket is very powerful It can generate mega newton frustums, Which will easily take you to space by abandoning the Earth's gravitational force
Number 2, there's a spacecraft called Orion
It will be used to transport astronauts from one place to another Now when astronauts are in space…Imagine being inside the International Space Station, If a little comes out of it, then 3 times more radiation falls on them than normal time Now this Orion spacecraft is being designed in such a way, So that it has the magnetic protective bubble of the earth, Beyond that, it can provide protection to astronauts. Now the radiations that come in space can come from different sources. But one of the most harmful is the radiation that comes The Sun occasionally releases some clouds of charged particles into space. And that may be on a periodic basis. These are called Solar Particle Events or SPEs. If the boss puts them on you, then in your long term Can be cancer or cardiovascular disease. The atmosphere we have around the earth, Or the other layers with it These layers protect us from many harmful radiations. But when they go into space, they are fully exposed to this radiation. There is no separate protective layer on the moon to save them. That's why Orion's astronauts will receive a signal from an SPE That's when they found the storage lockers inside the capsule floor of the spacecraft They can go there and protect themselves. You see, living in space is a very difficult task.
Number three thing, very interesting.
As we have the International Space Station, We will make such a small space station in the moon. Which is called The Lunar Gateway Granted it will not be permanent like the ISS. It is a temporary platform. Still, I need an astronaut on the moon Or any short period there, Research or any research is required in a short period of time, They can do that within this Lunar Gateway. That has greatly increased the possibility of human presence in the moon in the long term. NASA was also assisted by the European Space Agency or ESA in designing the Lunar Gateway. So there is an international collaboration in the project. It is not the case that only the USA is doing this. The last thing, which is the most challenging. How do you land on the moon? Even when landing a plane, we know how much more important it is to land than to fly in the sky. This is why when you land on the moon from the Lunar Gateway, This is the problem of landing, the measures taken for this, This is called Human Landing System or HLS. And this is where NASA, along with other commercial companies, Like Blue Origin or SpaceX are working. The landing module of the Apollo mission, It was the kind of thing you only go once and come back for. But the landing system of the Artemis mission this time, It's not just once, you can use it multiple times. You can use it in multiple missions, you can use it more than once. Which is a big milestone of this mission. Now this whole Artemis program is arranged in 3 stages.
Number 1, Artemis One.
Here the SLS rocket will only go around with the Orion spacecraft. It's like a test flight, there will be no people. This is what was launched today. When Artemis Two goes, Then Orion will go, the SLS rocket will go, and a crew will go with it. That is, a person will go, and come back to earth through the whole circle. Here I have often heard that both may be sent. It is not yet certain, if people will go to this Artemis Two Then it will be the farthest space travel by a human. Before this, humans have never gone so far into spacewalk have only sent robots to Mars, no humans. And that previous plan in Artemis 3, A woman and a non-white man could be sent to the moon. Damn bro, it's so hot now. Everyone should be sitting in that south pole of the moon.
Stay cool
In this regard wild poet Pablo scotia has already said, We actually live part time in life, and sweat full time. It's so hot, bro, I can't stand it anymore. are yar koi AC chillador yar! Now you may be wondering why NASA is spending so much money to send people to the moon.
Number one benefit
We want to go to Mars. So send people to the moon, This can be a test bed, like a laboratory, It can be seen experimentally in the moon how people will behave if they go to Mars.
Number two
Many of today's discoveries are coming from our space technology. Like those of you who run the occasional marathon, They look like a shiny sheet called a space blanket. It was made by NASA to protect its astronauts from various harmful radiations. For those of you who have seen Better Call Saul, there is Saul Goodman's older brother, Chuck McGill has a syndrome called Electromagnetic Hypersensitivity. And when it goes around an electrical object, He felt electromagnetic radiation coming into his body. Electromagnetic radiation is coming, and there is always a space blanket like this.
Thing number two,
Now that we have got such high quality cameras in our mobiles, It is the result of a study of digital image sensing at NASA's Jet Propulsion Laboratory.
Complementary metal oxide semiconductor or CMOS image sensor,
This is why the shape of the camera is so small. And phone camera or these places, We can record very high definition videos. Number three thing, vacuum sealed food. Astronauts could eat it if I sealed the food in a vacuum Then it is being preserved for a longer period of time. That concept is now being used in our everyday food. A technology in space later helps the Earth in many ways.
Why is this NASA program named Artemis?
You know, the name of that space mission in 1969 was Apollo. Apollo is a Greek god. And this god Apollo had a twin sister named Artemis.
There is an interesting story
Artemis sends a hunter into the stars to hunt. And this hunter's name is Orion. Do you understand that this was not a space craft? Its name is Orion Spacecraft. At one point, Apollo saw the intimacy between his sister Artemis and this Orion. So you see, Umm umm there was something between Apollo and Artemis. I did not understand this, this was given to me by Labiid. The storyline between Jaime and Cersei in Game Of Thrones, George RR Martin got this type of idea from such mythology.
But I don't know anything. Now you may have a question that, Why has NASA not actually sent their astronauts to the moon for so long? There are several reasons behind this. Number one, money. NASA's budget in 2019 was $21.5 billion, which is comparatively small. This money has been divided again for the James Webb Space Telescope
Which you have heard about a few days ago Now that the space launch system is done, money is pouring in behind it. So all in all, the man who will actually send to the moon, It became very difficult for NASA to manage the money for this. Just to give a comparison, The US military spends about 680 billion dollars every year. Where is 21.5 billion, where is 680 billion? Even so, these programs cost a lot of money. Number two, presidents sometimes cause a lot of problems.
In 2004, the Bush administration came and told NASA, look, replace the space shuttle And somehow manage to send people back to the moon. So then NASA under their Constellation program Arranged a human space flight program for 5 years at a cost of 9 billion dollars It designs, builds, tests. But when Barack Obama later came into office, Then a report comes to him that NASA has caught the cost of their program It was not appropriate and because of this the program was closed by Barack Obama
Another program SLS is the most powerful rocket, There started pouring money. Then what happened? The previous $9 billion NASA project is dying in the field. Or delays, due to which the cost of the project increases a lot. Then when Donald Trump came again, He then began pouring more money into missions to send humans from SLS back to the Moon and Mars. So this is how presidents screw up NASA's plans. Because of this, the cost of NASA increases a lot, a lot of time is lost, and scientists lose a lot of attention.
Number three thing
There are some technical problems in the moon. The soil of the moon is a little dust type, it is called lunar dust. It can be up to several inches deep in some areas. And when exposed to the solar wind Then they become electrostatically charged. Then the space suit, the space vehicle
Or there is a system A large amount of these tend to cause abrasion or erosion. Because of this, staying permanently on the lunar surface is a very difficult task. If you want to stay for a long time, you have to come up with a better plan. Better technology should also be brought. Now as SpaceX is planning, there are as many heavy industries in the world
All these will be lifted and taken to the moon. Earth will be declared a residential zone only. A light industrial zone, where there will not be much pollution. As much pollution as we will put into the moon. If this is done Then the moon will become a big influencer in the world economy. You see, it's not just the United States, All other countries of the world will be involved. Who will get how much space on the moon?
