Let's look at how it gets up. Then how it gets down. But first, this little tidbit. Lift a rock up 6 feet and drop it. Down it comes. Lift it a couple of thousand feet and drop it, it falls. Lift it several miles and drop it, bombs away. How about if we lift it straight up into space and drop it? It's up above the atmosphere, so what happens? It falls back down, that's what. Gravity has a funny way of hanging onto things. Even things in space near earth. Notice that it was not stated that the object was in orbit. It wasn't. It was only in space. Onward. When things are put into orbit, they have to be lifted and accelerated to achieve an orbital velocity for the altitude they are at. When the shuttle goes up, it pitches over near the top and accelerates along an arc that injects it into orbit (NASA calls it orbital insertion - and so can you). We're in orbit. Think about a weight on a string that is being whirled about a person. The string (gravity) pulls in, and the velocity of the weight keeps it wanting to move out. The forces are balanced, are in equilibrium in this instance. How do we get down? We point the tail of the vehicle in the direction that we are going and briefly fire the retro rockets (we have a short burn). This slows the vehicle down and gravity, which has been pulling all the time, draws the vehicle back toward earth in an arcing path. Re-entry had begun the moment we did the short burn, and now we're set up to heat it up when we begin making contact with the upper atmosphere. Atmospheric friction allows us to bleed off speed and slow up enough to land the vehicle. What the thrusters began to take us out of orbit, friction and drag have finished.
What else can I help you with?
What causes the earth to be slowly falling toward the sun?
Our Earth is not in a falling orbit.
What causes the cycle of seasons in earth?
The tilt of the Earth's axis in relation to the plane of its orbit.
Why is the Moon's orbit tilted?
Maybe because the earth's tilted orbital plane causes the moon to orbit tiled, if the earth was straight it has said that the moon would orbit straight line.
What do astronauts fly in?
Astronauts in their spacecraft (such as the Space Shuttle) are lifted into space by huge rockets which accelerate the craft to "escape velocity" (about 25,000 mph). This puts the craft into orbit around the Earth, its forward velocity balancing the continuous pull of gravity. When they are ready to return to Earth, they use rockets to slow down, and gravity pulls them back out of orbit. When astronauts travelled to the Moon, another smaller rocket pushed the Apollo spacecraft out of orbit, and carried it to the gravitational field of the Moon. Another rocket firing pushed the craft back to Earth. Unmanned space probes have travelled to even farther distances from Earth, including the outer planets Uranus and Neptune. Most of the travel is coasting, because there is practically no matter in space to slow a spacecraft down.
What does the 23.5 degree tilt of the earth cause no earth?
The axial tilt of the Earth's spin (relative to the ecliptic, or the plane of the Earth's orbit around the Sun) causes our seasons.
How long would it take to travel to the moon by rocket?
Apollo took on average 2.9 days from leaving Earth orbit to injection into Lunar orbit, and basically the same on return.
What would happen if the thrust of the rocket at take-off was not enough to put the rocket in orbit around the earth?
If the thrust of the rocket at take-off is not enough to put the rocket in orbit around the Earth, it will not be able to overcome the gravitational pull of the Earth and achieve the necessary velocity to stay in orbit. The rocket would likely fall back to Earth due to gravity.
Does it take less time for a rocket to return to Earth than to achieve orbit?
Usually the other way around ... it's a question of the rate of energy expenditure.
What are the largest rocket bilt?
first person to orbit the earth
What is a reuseable vehicle that goes into orbit like a rocket and then glides back to earth like an airplane?
rocket
Why does the rocket have to go sideways?
The rocket needs to go sideways to reach orbit. By moving sideways fast enough, the rocket can overcome the force of gravity pulling it back towards Earth. This sideways velocity allows the rocket to enter a stable orbit around Earth.
What is space oddity about?
The song is about the launch of a rocket containing astronaut Major Tom. A problem develops during the spaceflight and Major Tom is stuck in orbit, unable to return to Earth.
Can a rocket go outside of the Earth's orbit?
Yes, a rocket can go beyond Earth's orbit. For instance, rockets have been used to send spacecraft to the Moon, Mars, and beyond. However, once outside of Earth's orbit, a rocket would need to rely on its own propulsion system to continue traveling through space.
How does a rocket get out of earths orbit?
A rocket gets out of Earth's orbit by achieving escape velocity, which is the speed needed to break free from the gravitational pull of Earth. The rocket's engines provide thrust to accelerate it to this speed, allowing it to overcome Earth's gravity and travel into deep space.
What causes the moon to orbit the sun?
Nothing does.Simply because the moon does not orbit the sun.The moon orbits Earth, not the sun. And Earth orbits the sun.Gravity is what causes planets and moons to orbit.
Velocity is the speed and direction a rocket must have in order to orbit he earth?
save
How do you use 'orbit' in a short sentence?
As a noun: The rocket placed the satellite into a high Earth orbit. As a verb: The satellite had to travel very fast to orbit the Earth.
