Yes. Gravity is what keeps them in orbit. If it were not for gravity, those astronauts would continue out into space in a straight line.
There certainly is gravity outside the atmosphere. For example, it is gravity that keeps the Moon in orbit around the Earth, and the Earth in orbit around the Sun.
Astronauts reach space by launching in a spacecraft, such as a rocket or space shuttle, that is designed to overcome Earth's gravity. Once in space, the spacecraft continues its journey to enter orbit around the Earth or travel to other celestial bodies like the Moon or Mars.
Astronauts and satellites stay in orbit because they are moving fast enough horizontally that the force of gravity pulling them towards Earth is balanced by their forward momentum. This creates a state of continuous free fall around the planet, resulting in a stable orbit.
Weight is an expression of the gravitational force acting on an object. When the space shuttle is in orbit around the Earth, it is held there by the Earth's gravity. Since gravity is still acting on the shuttle and the astronauts inside, they still have weight. They are described as "weightless" because an object in orbit is in a constant state of free fall.
The major force that keeps the moon in orbit around Earth is gravity. Gravity is the attractive force between two objects with mass, causing them to be drawn towards each other. In the case of the moon and Earth, Earth's gravity is responsible for keeping the moon in its orbit.
Yes, but they do not "feel" gravity, because they are falling - "free fall" in orbit around the Earth.
The weightless astronaut landed on Mars, which has no gravity.
Weightlessness in orbit is not due to being beyond Earth's gravity, but rather to being in a state of continuous free fall around the planet. In orbit, the spacecraft and everything inside are falling towards Earth at the same rate, creating the sensation of weightlessness. Gravity is still present in orbit but it is balanced by the spacecraft's forward motion, creating an apparent state of weightlessness.
There certainly is gravity outside the atmosphere. For example, it is gravity that keeps the Moon in orbit around the Earth, and the Earth in orbit around the Sun.
earth's gravity
An example of gravity is the force that causes objects to fall to the ground when dropped. Gravity is what keeps planets in orbit around the sun and astronauts in orbit around Earth. It is a fundamental force of nature that attracts all objects with mass towards each other.
Astronauts reach space by launching in a spacecraft, such as a rocket or space shuttle, that is designed to overcome Earth's gravity. Once in space, the spacecraft continues its journey to enter orbit around the Earth or travel to other celestial bodies like the Moon or Mars.
The massive speed and acceleration of the spaceship is so great, that they are able to escape Earth's gravitational pull. Then at around the correct altitute, they can orbit the Earth safely.
Gravity
Astronauts and satellites stay in orbit because they are moving fast enough horizontally that the force of gravity pulling them towards Earth is balanced by their forward momentum. This creates a state of continuous free fall around the planet, resulting in a stable orbit.
The mutual attractive force of gravity keeps the Earth in its orbit around the Sun.
Gravity is the force that keeps the Earth in orbit around the sun. The sun's gravity pulls the Earth towards it, causing the Earth to move in a curved path around the sun. This gravitational force is what keeps the Earth in its stable orbit and prevents it from flying off into space.
