Space Tour on Earth
The first space traveler in the history of humanity, Tito, was born in 1941,
After NASA Jet Propulsion Experiment Room engineer, involved in the design of the orbit of the Mars and Mercury exploration spacecraft. In 2000, he signed an agreement with Russia to personally sponsor $20 million to maintain Russia’s “Peace” space station, on condition that he personally went to the “Peace” space station for a space flight.
Since the Russians finally abandoned the “Peace” space station, Tito turned to the International Space Station, which was built by 16 countries including the United States, Russia, Europe, Japan and Canada. . On April 28, 2001, Tito took the Russian “Union TM32” manned spacecraft from the Baikonur launch site with two Russian astronauts. Two days later, the spacecraft successfully docked with the International Space Station. Tito was a Russian astronaut. Accompanied by the International Space Station, six days later, the “Union TM31” spacecraft returned to the ground to return to the ground, ending the first space tourism that caused a global sensation.
From the day when space travel became a reality, humans have always had a way to the universe, relying on rocket propellers. But astronauts can quickly try another new experience: the solar sail.
Light is made up of tiny energy clusters called photons. The solar sail works by reflecting the reflected sunlight back. Since the effects of force are mutual, the solar sail pushes the photon back. Photons also have a reaction to the solar sail. It is with this reaction that the spacecraft is “pushed” out of the galaxy. Experts say that sunlight is an inexhaustible source of energy. From this point of view, the use of solar sails in long-distance space travel is superior to the use of traditional rocket propellers.
A Texas-based company called Team Encounter announced that they are working on a solar sail called “the first human star ship” that is the size of a football field. The person in charge of the company said that when the “Starship” was launched, the huge solar sail would push the “Starship” through the solar system and into outer space. TeamEncounter has designed a special piece of paper. Anyone who pays $50 can write their own greetings on one of them, attach their own photos or their own DNA samples, and entrust the “Starship” to bring them in. Space.
Astronauts in the space of the Lingbo microsteps are enviable, but can not be expected. But now there is a way, as long as you spend thousands of dollars on a weightless aircraft, you can experience the feeling of space travel in the Atlantic Ocean.
“Diving” over the Atlantic Ocean
A few days ago, Cleveland’s high school teacher, Mike Hickey, and 38 other teachers took a specially modified jet. “Diving” (up and down) over the Atlantic Ocean, conducting a “space trip.”
Hickey is 54 years old and weighs 89 kilograms. He laughed like a child: “Ha ha ha, I have quality, but no weight.” Weightlessness is a part of his lecture, which is more vivid. He said that the children will see on TV – a fat old man floating in the air, as if there is no weight at all… He will also tell them: “He is me, lost weight, and is in a state of weightlessness.”
Zero Gravity is not a dream
The weightlessness has always been a problem faced by astronauts and scientists, but now it has entered the homes of ordinary people. Millions of millionaires, doctors, teachers, and college students can experience the feeling of space flight in less than five minutes for less than $4,000, enjoying a brief freedom of zero gravity.
Alan Radveg, former deputy director of NASA, said that in more than 40 years, the world’s two major space agencies have allowed thousands of scientists, engineers and astronauts to carry out weightless flights, and even include The actor of the movie “Apollo 13”. Radewig is currently the head of the North Space Operations of Northrop Grumman in the United States. He estimates that about 50,000 people have been involved in weightless flights. The French doctor also asked a patient to take a new space company’s aircraft for the first time in a weightless state of human surgery – the removal of cysts on the arm.
French New Space, Virginia Space Adventures, and Florida Dream Adventures offer travelers a weightless flight service. The special jets they provide are not from US zero-gravity companies. It is a space organization from the European Space Agency or Russia.
Henry Lambrett, professor of public administration and space policy at the University of Syracuse, USA, said: “This is a hot spot for the future and a sign that the space program is maturing.”
The early autumn morning, they boarded the plane. On the Atlantic Ocean, the plane rushed straight to the height of 10,000 meters and then dive 2,500 meters to the surface. When the plane ascended, they experienced overweight – 1.8 times the normal gravity of the Earth; when the plane descended, they felt weightless. The whole process is only a short 50 seconds.
There are 35 seats at the rear of the aircraft for use when landing. In the middle is the game area where passengers can walk in the air under weightless conditions or “squash” the floor when they are overweight.
The teachers floated into the cabin, crashing into the walls, ceilings and floors, colliding and colliding with each other; bursts of laughter and applause. In the air, someone started the weighing experiment; someone played a half-ring coil spring (a toy); others tried to eat candy and catch water beads. What’s more interesting is that three people even put on a red cloak, their arms are stretched forward, their feet are squatting backwards, and they are all super cartoons in a cartoon.
The whole flight lasted 2 hours and 6 minutes. The teachers truly felt the gravity of Mars once (about 1/3 of the Earth’s gravity) and the gravity of the 4 moons (about 1/6 of the Earth’s gravity). And 11 weight loss. When they walked out of Dallas International Airport, they were filled with emotion.
Treisi, a high school teacher from Gehana, Ohio, said: “It’s really amazing.” Her flight partner Hickey said: “I feel that there is a feeling of soul. Student They saw the lens of my face falling down to the floor, and I was so excited that I died.” Teacher Kali Connelly of Howard Middle School in Maryland thought it was like a roller coaster, but not. She said: “You suddenly feel that you are very powerful and can do anything.”
In fact, no one can tell this feeling. Astronaut Jerry Lienenger worked for four months at the Russian “Peace” space station. He said: “When most people are asked about the feeling of weightlessness, the most answer is struggle. Because we are used to gravity, we don’t know how to describe the state without gravity. It is subtle and indescribable.” /p>
Peter Dimonds, CEO of Zero Gravity, has more than 40 weightless flights. He said humorously: “How can people who have not eaten chocolate understand the taste of chocolate?”
Airsickness is not needed
NASA’s first weightless aircraft is called “jetted” Comet, now retired. A new generation of weightless aircraft will be more considerate of the tourists, passengers can easily get the breakfast in the air when floating.
Noah McMachho, marketing director and aviation briefer for Zero Gravity, said that fast up and down movements do make some passengers feel uncomfortable, but the designers of the flight are doing their best to make people’s sports react. To the lowest. He said that three people in the last 400 people were airsick, and only one in this flight responded.
The company will provide airsickness to passengers before boarding the aircraft, and advise passengers not to eat protein and dairy products, which is good for reducing airsickness. The company has also reduced the number of round-trip flights, because based on past experience, people usually get airsick when they fly to twenty or thirty laps. If the passenger feels uncomfortable, the blue vomit bag is around.
The study found that the main feeling in flight is not uncomfortable, but a feeling of freedom and disappointment. Two or three seconds before the end of each weight loss state, the technical operation person will use the loudspeaker to remind people to point their feet to the floor to avoid head landing. Teacher Connelly said with deep feeling: “Everything comes too fast. Every time I hear the reminder, I really want to shout: ‘No, let’s slow down!'”
The new version of “Westward Sports”
Hundreds of science teachers have gone through the modified Boeing 727 to go to the Atlantic Ocean to experience weightlessness under the organization of Zero Gravity. The cost per person is about $3,750, all paid for by Northrop Grumman, in order to encourage the spread of science.
Dimondes said that about 3,000 passengers have paid for the ticket so far. He hopes that 10,000 people will participate in this magical “space trip” every year.
Now, many Americans are eager to take risks. American University professor Howard compared weightless flight to the “westward movement” of the 1990s – the first courageous Americans established border villages in the west.
McMikeho said: “Flight becomes safer and more economical. The only difference is that we are up now, not westward.”
