Orbit's ordeal in space travel from Tyson to Newton: not ahead of the stars, but before the moon!

- Unveiled-Jay Vasavada

- In the name of 'space tourism', this rich man is said to have gone only two millimeters (yes, mm) away from the earth. Not even the International Space Station until 1 centimeter away!

"We don't know, but that doesn't mean you

Can't ... "

Meaning: It is true that we do not know, but that does not mean that we will never know.

This is a wonderful quote for knowledge seekers from renowned astronomer Neil Digras Tyson, who heads the space department at the Science Museum in New York about the mysteries of the universe and space. Remember the series 'Cosmos' which was also shown on television years ago? It was led by scientist Carl Sagan. Carl Sagan's elephant contribution in creating curiosity about sky / space in many people of the world and satisfying it with a simple scientific explanation. Like his disciple and Obama, black American Neil Tyson. Master of simple explanations of seemingly difficult space sciences. The books we have written about the cosmos in Gujarati are a building built on the foundation of Carlo Sagan. But still less reached Neil Tyson (whose recommendation was on last year’s vacation reading list).

This Neil Tyson has just hit the headlines again after Richard Branson's 'Space Travel'. Richard Branson (Virgin Galactic) and Jeff Bezos (Blue Origin) are competing for space tourism in the world media after Elon Musk's Mission Mars. An airport-like spaceport was ready in New Mexico. New money is coming into the space economy. Today, the િયન 20 billion sector is projected to grow to જ 200 billion in two decades by 2020. It is estimated to be more than that (ટ્ર 1 trillion).

The potential of this so-called 'Rich Boys Timepass Toys' space tourism is not so appealing to everyone. There was a લાખ 2.5 million ticket for the Virgin Galactic Space Flight to return in an hour. Not everyone can afford it, but in this 'nish premium' market, only a few thousand can be afforded. Who gets the satisfaction of spending space by spending money, sorry to spray the roof on the world! After the departure of Richard Bronson on July 11, Jeff Bezos will be gone by the time this article is published. We both danced on the ground with our hands clasped. Sirsha Bandola of Indian origin flew with Bronson and Sanjal will go to Gawande with Bezos. Kalpana will be followed by two more Indian women astronauts after Sunita. Even the empty name Indian. The rest is to study abroad, to study abroad. How much of our talent has gone from IT to space, spanning America, the West!

But did Tyson question whether this was actually called space travel? He jokingly said that 'space' has no place to go. In fact, the earth is also in space. So we flew a little bit into space travel: (The confusion of these words was discovered in Sanskrit by coining the word space) But Tyson said that the Branson Bezos who are competing do not technically go into space. The only place we can see in space tourism right now is the International Space Station (on which the article was written 15 years ago - ISS). Where the capacity for visitors is very limited. But the journey of Virgin Galactic or Blue Origin is not possible till then. That is why it is not called space travel, but 'sub orbital' travel. It can be Bhadrambhadriya Gujarati like a semi-orbital orbit. Orbit means orbit.

In the video on the CNN channel, Tyson took a medium-sized globe of the Earth that he had at school in his hand and explained that if you scale the Earth and make it look like a sphere (like a watermelon), the moon like an apple is ten meters away from it. Getting there is called actual space travel. Elon Musk's SpaceX rocket is set to make a lunar voyage to Japanese billionaire Yusaku Maezwa 205, who has ordered eight other names online from the lottery system. In which the unlucky ones who can never afford to go there will be able to travel in space if their destiny is unlocked.

But NASA flew Alan Shepard at the Cape Carnival, a similar journey of up to 5 km in the sky that has just happened. Now it's new in a new reversible aircraft (Allenbhai as always landed in the water, not in a plane on a spaceport like Branson). But if the apple-sized moon is 10 meters away from the watermelon-sized earth, then in the name of 'space tourism', this rich man is said to have gone only two millimeters (yes, mm) away from the earth. Not even the International Space Station until 1 centimeter away!

And this revelation reminded me of an old yet new subject that was not understood by many despite being taught. Due to which our smart phones get location through GPS navigation through which channels in TV, movies in OTT - series or the whole world running on the Internet. This is a very important subject for launching satellites. Orbital to orbit after the boundary of the Earth's atmosphere?

"There should be a border where aerodynamics stops and aeronautics starts. Whose space below belongs to each country (planes cannot be flown in each other's space) but in front of which the infinite sky does not belong to anyone! "

This was written by Theodore von Carmen in his autobiography. Which can be considered the pioneer of aerospace. And the imaginary boundary of a circle of 100 km around the earth is also called the Karman line. Understand that aerodynamics means flying planes and aeronautics means flying rockets. Remember that picture of school science? Let's do a revision. 18.5 km troposphere around the globe, stratosphere up to 30 km, mesosphere up to 5 km, thermosphere up to 200 km and exosphere up to 10,000 km.

Reading this, it seems that the space travel shown in the films, the outer space may have started at a distance of tens of thousands of km. But actually what we call the 'atmosphere' is the atmosphere, where the mesosphere and the thermosphere converge. Technically, Branson Bezos can fly 6 km in outer space. Extremely rigorous training, intended to last for days called 'Zero Gravity'. Terry Wirts, the former commander of the International Space Station, who spent 215 days on the International Space Station, said that the same word could not be used for "astronauts" who are trained to endure everything from toilets to food and thus return to the wall for an hour or two. It's like the sky is clear, so change the word. If you get older, keep the name Juwansinh or Rupali!

But this discussion has given many Mango People a new direction to the common man. This seemingly distant 'space' is really so close, Lya! Look, 3 km is about Ahmedabad to Anand. Assume that the orbit of this orbit starts at 100 km. If you go from Rajkot to Junagadh through Karman line, you have to get up in the same direction, just. This is not a difficult case. Go upstairs and take a selfie with the chubby earth. (By the way, forty kilometers above the earth, you can theoretically go high in the balloon described by Jules Verne).

Well, according to Neil Tyson, this is not even the height from which the earth looks like a moon! From this height in front of the vast circumference of the earth, just a little 'curvature' means a turning surface! That's why the images of marketing bragging on Branson's head went viral, but not of the earth seen from the balcony of the sky. Yeah Al that sounds pretty crap to me, Looks like BT aint for me either.

Although it is interesting that the science behind this journey is taught engineering, but like Dabangbhai, many do not understand. So we're mostly producing parrots of 'everything was there', not real space scientists. ISRO's Achievements Aflatoon is also a building erected on top of the ready-made technology transfer after Torsia flew the flag from satellite to equivalent astronaut after World War II. That is why we are lagging behind years in innovation that astonishes the actual world. As much as the cultural vanity fills the mind in the student state, then there is no room for the wonder of science.

But if we want to talk about space science, orbit, then the chanting begins with the chanting of two primordial names. Einstein and Newton. In it Einstein's area Elon Musk is aiming for is a trip to a real universe like Mars. Musk is a scientist like Steve Jobs. It has to be earned in space tourism, but its target is the astronomical journey of real astronomy like NASA. But the space tourism that is rampant right now is actually the science of launching a satellite rocket. In which Newton is dominant. Without the explanation of inertia, gravity, access to those three rules, neither this would be space tourism nor the internet would be like the lifeblood of our online digital world!

In Newton's kinetics he had a basic curiosity about how things move from one place to another. Newton's experiment, known as cannonball, not cannonball, but thought, (Thought Experiment)

Under the circumstances, if the ball bounces in the sky, it will immediately come down due to the gravity of the earth. But long sixes like Gail or Dhoni keep floating in the air for a few seconds before the ball comes down. The ball does not go in a straight line as if hit by a bat but forms a long semicircle. This is because the velocity gained at the time of stroke does not increase but decreases per second, and the gravity force increases. But what if the speed of the ball increases per second?

So instead of falling down from the cannon into the sky with a certain force (imaginary if it maintains its speed) according to the gravitational nucleus, the Earth's rotation and orbit around the Earth take some rotation according to its velocity due to two factors. Don't swallow immediately because we've felt the bullet hit the air barrier. But if there is no air or if it is negligible? Again Newton, the motion of a moving object can continue motion if it is not stopped by energy friction. Yes, it requires enough thrust-energetic push to supply energy. Why do car-bike tires have a rough surface on the carved asphalt road? This means that the wheels do not slip and the brakes feel tight. Prevents friction motion.

That's all there is to it. To launch a celestial man-made satellite aka satellite orbit, a supersonic Concorde passenger jet plane flies at a speed of 215 km per hour relative to the speedometer of our car. But when Russia launched the first satellite 'Sputnik-1' at the age of 18 and launched the first bow of today's digital age, its velocity was 2,500 km per hour / hour. . But it is in the most popular space part called 'LEO'. LEO means low orbit distance up to 3000 km from the earth. Weather, espionage, TV, broadband (now satellite based WiFi is not very good. Both Musk and Bezos are setting up a network of thousands of satellites.) Everything is in this LEO. Space tourism has not reached there yet.

MEO over LEO; Medium means orbit. Which does not have special ‘traffic’ of satellites. But there are also clusters of GPS from the US, Galileo from Europe, GLONASS from Russia, and Baudou Satellites from China. (Even the four real superpowers across the earth!) Which come to us in the work of navigation. But his main job is military intelligence. Above it is a sweet spot - in geosychonic orbit. Where the rotation of the earth and the rotation of the satellite match each other equally. A satellite in a 'geo stationary orbit' (above the equator) orbits the earth in the same position. If nothing else can be seen around the side window of a train running at the same speed, the exit will feel stable.

The problem is that the lower the altitude, the higher the speed at which a satellite called a rocket is fired from a rocket-propelled grenade so that it can orbit the earth for decades. For example, NASA's magnificent Hubble Telescope, located at a distance of 5 km above the Earth, completes its orbit around the Earth in an hour and a half (2 minutes). But the GPS satellite at 30,200 km can be completed in twelve hours! More important for this is the location of the rock in the sky. Thus the earth is round and space is chomer. So it is cheaper and easier to leave the horizontal rock. But in this, if the forests and mountains are horizontal, then they should be left upright. Also, the place is set closer to the place from which the time is to be determined.

Only 2/3% of the rockets that go to the satellite stop the engine. The load of other material has to be included in 2/3%. This is the reason why human space tourism cannot go very high, because the so-called propellant requires a very large amount of fuel. (This is the beginning of a permanent weeping environment and the welfare of so many poor people at such a cost.)

To keep the Earth's gravity from shaking, the rocket has to bend straight to take a curved path (because the Earth is round, rotates) to get out of the prevailing atmosphere. 'Does. But when the rocket escapes from the rope or the fast bowler swings the ball, it accelerates the moment and maintains the balance between the two opposing factors by the nut acrobat running on the rope. When the rocket flies in one direction, the gravity of the earth pulls in the other direction. (Even if it is called zero gravity, there is a little bit of gravity in space. But the effect of this effect is very large and in comparison, everything seems to be the same, the blackness of the vacuum is so dark that it does not come to mind) In this, it constantly revolves around the earth!

It is still light years, if not years, to go in that orbit and do Antafera, to go there and open a box of dried vegetables and have a feast!
