This Is The Biggest Myth About Outer Space, According To A NASA Flight Controller

What is the biggest myth about the universe? Originally at Quora: By acquiring knowledge and sharing, people can learn from others and understand the world better

What is the biggest myth about the universe? There is no gravity in space. People do not know what weight loss is. They saw the astronauts floating inside and outside the spacecraft and reached the conclusion that there was no gravity.

There is every mass and space, gravity exists. Gravity is the space-time curvature due to the presence of mass. Space astronauts can also feel the influence of gravity due to the sun circling around the sun. The influence of gravity on the International Space Station on the Earth's moon and the Earth's orbit is also felt by astronauts floating inside and outside the spacecraft. If you do not feel these effects, the astronaut will not get in orbit.

At the altitude of the astronauts on the International Space Station, the effect of gravity on the earth is 75 m / s ^ 2. This is only about 11% lower than 81 m / s ^ 2 you and I feel on the surface of the earth.

They seem to be floating because they are not weighty and are in free falling condition. Spacecraft on the orbit of the earth has fallen to the earth (due to gravity), but the spacecraft is advancing at a sufficiently high speed that the traveling route is not a straight line but a curve that goes round the earth. [1] Astronauts are falling and their spaceships are falling. When both are falling, there is no force against the other, so there is no weight. We can simulate this free fall in a tall, vacuumed room.

Imagine that an astronaut on the earth stands on the scale. Since gravity pulls the astronaut towards the center of the earth, the ratio shows weight, but the earth gives up and is reluctant. Weight is a sense that the earth does not deviate

Imagine that an astronaut who is orbiting the earth is in space now. He is the same size, he is standing there. Is weight displayed? No. Do not touch the earth so that the astronaut and the scale can fall together and the earth can push back

The International Space Station and its crew are falling free. They are falling towards the center of the earth, but they are also moving sideways quickly, so they are losing sight of the earth. We lose weight because there is no Earth's surface to counter the International Space Station or its crew

[1] Robert Frost's answer If the gravity of the sun is always pulling the planet towards it, why does not the earth get drawn into the sun?

In order to investigate how to step on the throttle around the ISS, I drove to the Johnson Space Center at NASA and met NASA flight controller Josh Paris. Paris is one of the people responsible for the console of the control room of the International Space Station or "mission control". His station name is TOPO - Trajectory Operations Officer. From the early days of manned space flight, the flight controller of the International Space Station was a high-tech staff member; Paris and his colleagues received years of professional training to reach their "sitting at the console" level It was.

Johnson Space Center officially opened in 1963, is a manned space center of NASA. The Johnson Space Center consists of 100 buildings that provide human space flight training, research and flight control. Astronauts from the US and international partners were trained in this place. This is the nickname of "City of Space" in Houston. In addition to the work done there, the NASA center also has a visitor center that attracts many guests. The existence of this center is another reason why real estate investment in Houston may always be a good idea.

At the Linden Johnson Space Center (JSC) in Houston there is a control center for Christopher C Kraft Jr., and all flight controls are managed in manned space missions. JSC is the leading international space station activity center of NASA, home of NASA's astronaut team and is selecting, training and providing astronauts as crew members of the US and international space missions. There are many other facilities operated by NASA such as Valops flight facilities on Volops Island in Virginia, Michoud assembly facility in New Orleans, Louisiana, White Sand Test facilities in Las Cruces, New Mexico.
