Leaving Earth exposes astronauts to various physical and psychological effects. Physically, they experience microgravity, which can lead to muscle atrophy, bone density loss, and fluid redistribution in the body. Psychologically, the isolation and confinement of space can impact mental health, leading to stress and anxiety. Additionally, exposure to increased levels of cosmic radiation poses long-term health risks.
Weightlessness
The astronauts from Apollo 11 returned to Earth by using the Command Module, which separated from the Lunar Module after leaving the moon's orbit. The Command Module re-entered Earth's atmosphere, and parachutes slowed it down for a safe landing in the ocean. The astronauts were then picked up by a recovery team.
Astronauts might feel a pang of regret upon returning to Earth due to experiencing the "overview effect," a cognitive shift in awareness reported by some astronauts when viewing Earth from space. This profound experience can lead to a sense of interconnectedness and appreciation for the planet, making the return to Earth's complexities and challenges emotionally challenging. Additionally, astronauts may miss the unique perspective, freedom, and camaraderie of space missions, which can create a longing for the extraordinary experiences they had in space.
Leaving Earth can have physical effects on the body due to changes in gravity and radiation exposure. It can also have psychological effects such as feelings of isolation and homesickness. Additionally, leaving Earth can have social effects as individuals adapt to new environments and interactions with others.
No astronauts have died on the moon. All astronauts who have traveled to the moon returned safely to Earth.
At what altitude does the Earth's gravity no longer have an effect on the astronauts or the space shuttle?
Weightlessness
astronauts leave earth by the liftoff of the space shuttle and rockets, it is called force of the rocket. The engine starts and liquid fuel comes out of the rocket and pushes them up.

The Overview Effect
a G is the force due to gravity. 2G would be twice the force due to gravity. Astronauts have to withstand multiple G when leaving the Earth's atmosphere.
All the astronauts used by N.A.s.A have walked on the surface of the earth.

This is known as free fall or microgravity. In this state, astronauts and objects inside the shuttle experience a sensation of weightlessness because they are falling at the same rate as the shuttle around the Earth, creating the illusion of being in a state of weightlessness.
Oh but it does affect astronauts on its surface. When Apollo astronauts traveled tothe moon and worked there, they landed, stood, hopped, walked, kneeled, drove, andset their tools on the surface. None of that would have been possible without thefamiliar effects of gravity, albeit 84 percent weaker than on earth.
