You can approximate weightlessness in a swimming pool. NASA astronauts practice maneuvers under water.
Earth has gravity. You cannot experience weightlessness on Earth unless you enter a specially made chamber that alters gravity. Astronauts get training inside special weightlessness chambers.
That happens because the objects are in free fall.
Experiencing negative gs, such as on a roller coaster.
Blood is one of the few biological systems that appear to be affected very little by weightlessness and free-fall.
You experience day and night by the rotation of the Earth on it's axis. The portion of Earth that faces the Earth is day and the other side is night.
Astronaut candidates do "parabolic training" on a plane nicknamed the "Vomit Comet" (due to its tendency to induce motion sickness in passengers) so that they can experience weightlessness before being launched into space. If a potential astronauts is found to not be able to handle weightlessness, it's better to find that out before they actually get sent there for a long period of time. Also, weightless training gives them experience in how objects behave in zero-gee, so it's not a surprise when they get there.

The weightless astronaut landed on Mars, which has no gravity.
You have to be outside of the gravitational pull in the atmoshpere. Answer: Weightlessness can be achieved:* in Earth's atmosphere in an aeroplane doing a dive or on carnival rides (Drop of Death)* when in orbit around the Earth or other body.* there are several points (Lagrange points)in the Earth/moon system where the gravitational attraction of the two bodies cancels out producing weightlessness.
In space, there is no gravity and one would experience weightlessness.
The astronauts would experience weightlessness.
In space, there is no gravity and one would experience weightlessness.
Weightlessness occurs in space. Astronauts circling the earth in space experience the feeling of weightlessness.
You can't

No. The weightlessness you experience in space is because you are essentially in freefall. Standing on the surface of the moon you would notice its gravity.
