Astronauts are in a continuous free fall the whole time they are in orbit. You may
now ask though, why don't they hit the ground? They never hit the ground
because they are traveling fast enough laterally that they miss the earth. In a
sense, yes gravity does affect them, that's how they stay in orbit, but they do
not feel the affects of it because they are always falling. If you were to sky dive
or jump off of a high surface, you would experience the sensation of zero G, you
just do not experience the no friction/ airless environment that they do. A quick
factoid, when astronauts come home from shuttle missions, from being in the
weightless environment for that amount of time, they actually loose some of their
muscle mass, in some cases the loss is so great that some astronauts will not be
able to walk away from the shuttle once it is back on earth. This is the main
concern on future Mars Missions. Being out of earths influence of gravity for
months on the trip to Mars can be fatal.

How do you think the gravity of Jupiter would affect any astronauts who might land there?
They die
What problems do astronauts face in zero gravity?
Astronauts face several challenges in zero gravity, including muscle atrophy, bone density loss, fluid shifts in the body, and changes in spatial orientation. These issues can affect bodily functions and create discomfort for astronauts during space missions. Adaptation to the microgravity environment is crucial for the long-term health of astronauts during their time in space.
Does gravity pull on astronauts while in orbit around earth?
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.
At what altitude does the Earth's gravity no longer have an effect on the astronauts or the space shuttle?
At what altitude does the Earth's gravity no longer have an effect on the astronauts or the space shuttle?
Are astronauts being affected by gravity?
yes
What causes astronauts to float?
Lack of gravity.
Why do astronauts not weigh less in space?
they do-there is no gravity
Why astronauts float in spaceALIVEGEEK?
Because of the gravity of the
How do astronauts overcome gravity in space?
Astronauts in space experience microgravity, where they are in a state of continuous free fall around the Earth. This creates the sensation of weightlessness. They do not completely overcome gravity, but rather experience an environment where the effects of gravity are significantly reduced due to the spacecraft's orbital motion.
Can astronauts fly out of space?
Yes, astronauts can fly out here and there as they live in zero gravity in space.
Identify the characteristic of gravity that is incorrect?
Gravity is a non-contact force that acts between two masses.
What is meant by the term 'artificial gravity'?
The term "artificial gravity" refers to using science technology to create gravity. This is usually desired by astronauts and space organizations such as NASA to keep their astronauts healthy and to minimize the effects of weightlessness on astronauts during long term space travel.
