Space Travel

Space Travel – The human curious mind has always tempted him to step beyond his surroundings and discover the unknown. He has not contented himself with discovering the corners of the earth, and his feet have reached space to see what is happening on other planets. Space travel is one of the most exciting and interesting trips. The opportunity to watch the planets and stars is not something that anyone misses, But how many of us can board spaceships and get ourselves into space? That is why many videos and images are recorded by spaceships and satellites so that everyone can see them and explore space and touch their wonders. Today’s carnival video also takes you into space and creates a different tour for you. Be with us and watch the earth from space for a moment and enjoy … We start with the evening effects of the earth; The lights of the cities flicker and let us know that the planet is in darkness. The aurora borealis is one of the wonders that amaze us on our journey today. Nothing can be more spectacular than the dance of colored lights over this planet at night and offer a spectacular view. Little by little, we see the light of day and the clouds that cast shadows on the earth and move; It is as if a cotton blanket has been placed on top of this sphere. A little later we return to the night and get closer and closer to the aurora borealis to see them from another perspective.

What is space?
Space is an almost empty space in which all the objects of the universe move. Planets and stars are very small points in front of the vast expanse of space.

The beginning of space – Space Travel
Air pervades the earth and forms its atmosphere. The farther we go from the ground, the thinner the air layer. There is no definite boundary between the Earth’s atmosphere and space, but most experts say that space begins at an altitude of 95 km (60 miles) above Earth. The space just above the Earth’s atmosphere is not completely empty. This space contains particles of air, space dust, and local pieces of metals or rock material called celestial stones. Different types of beams are also present. So far, thousands of artificial satellites have been sent to this region from space. The Earth’s magnetic field extends beyond the planet’s atmosphere and is visible in space. This magnetic field absorbs electric particles in space, creating regions of radioactivity called Van Allen belts. A region of space where the motion of charged particles is controlled by the earth’s magnetic field. Magnetosphere (magnetosphere). This region is like a teardrop that starts near the sun and extends towards the earth. The Earth’s magnetic field recedes beyond this region to the Sun’s magnetic field. But the situation with the Earth’s gravitational force is slightly different in that this force is still effective at distances such as 1.6 million kilometers (1 million miles) and can keep satellites in orbit.

Space between planets, space It is called interplanetary. The sun’s gravity controls the motion of the planets in this region and leads to the rotation of the planets around the sun. Long distances generally keep the planets away from each other in interplanetary space. For example, the Earth orbits the Earth 150 million kilometers (93 million miles) from the Sun. Venus is 110 million kilometers (68 million miles) from the Sun. Venus is a planet that, when placed directly between the Earth and the Sun, has the shortest distance to Earth, 40 million kilometers (25 million miles). In such circumstances, Venus is 100 times the distance of the Moon from the Earth. Space between the stars, space It is called an interstellar. The distances in this area are so great that scientists do not use kilometers and miles. Scientists use the unit of light-years to measure distances on an interstellar scale. One light-year equals 9.46 trillion kilometers (88.5 miles). This is the distance that light travels at its fastest speed of 792/992 km (182/282 miles) in a year. Objects that have not yet been properly identified exist in interstellar space.

Entering space and exiting it – Space Travel
Extreme gravity is the biggest problem for space missions. A spacecraft is sent into space under certain conditions of speed and direction. Gravity weighs everything on the ground and causes objects to fall to the ground. On Earth, gravity acceleration is known as g, which is about 10 meters per second. A powerful rocket called a launcher helps the spacecraft overcome the force of gravity. All launchers have at least two rocket units. The first part must provide the necessary pressure to separate from the ground. For this job, the pressure of this base must exceed the total weight of the launcher and the spacecraft. The launcher achieves this pressure by burning fuel and expelling the resulting gas. The engine fuel of these rockets is a special compound called propellant. This fuel is a combination of solid, liquid, and oxygen fuel, the substance that provides the oxygen needed for fuel in space. Liquid oxygen is usually used as oxygen. The minimum acceleration required to overcome gravity and stay in orbit is called orbital acceleration. This acceleration is about g3, which is three times the acceleration of gravity.

A launcher usually reaches this acceleration within 9 minutes. At an altitude of 190 km (120 miles), the speed required for a spacecraft to orbit accelerate, and stay in orbit is about 8 km (5 miles) per second. Most rockets are brought to the launch pad by a vehicle and then They are in their proper place. At this time, the propeller enters the rocket fuel chamber through special pipes. At the moment of launch, the rocket engines of unit one are turned on until the force of the combined pressures of the engines exceeds the weight of the rocket. This force causes the launcher to detach from the launch pad. If the launcher has several rocket units, the unit one rocket runs out of fuel after a few minutes and separates from the launcher. At this time, the rocket of unit two starts working and a few minutes later, its fuel is finished and separated. If necessary, another small rocket unit is turned on to achieve orbital acceleration. The space shuttle launch is slightly different from what has been said. In addition to the main rocket engines, the shuttle has other accelerator engines called solid propeller boosters, which burn the liquid propeller. The forces from the boosters combine with the main engine power, causing the launcher to detach from the platform. About two minutes after takeoff, the boosters detach from the shuttle and return to Earth by parachute. The main engines remain in operation until the shuttle has almost reached orbital acceleration. The small engines then keep the shuttle in orbital acceleration.
