It actually means that the astronaut is in free fall, and doesn't FEEL gravity. Gravity does affect the astronaut, so the astronaut will still be accelerated towards Earth. However, the astronaut won't feel the gravity.

No. The speed of any orbiting body depends only on the energy of its orbit, meaning mainly its distancefrom the central body.When a Space Shuttle astronaut performs a 'space walk', and momentarily unhooks his feet from thehull of the shuttle, he and the shuttle are both in earth orbit. The astronaut and the shuttle have thesame orbital speed, and they stay close together, even though the shuttle has somewhat more massthan the astronaut has.
because both the astronaut and the satellite is attracted towards the center of the earth
Gagarin made one orbit of the earth in 108 minutes before coming back home.
Scott Carpenter was the fourth astronaut to orbit the earth.
An astronaut can never be in zero gravity in our solar system, because there is gravity (usually) from the Earth, and always from the Sun. It is important to distinguish weightlessness from zero gravity. Weightlessness occurs in a gravity environment in which the person is freefalling, hopefully in orbit. In a freefall condition, there is no friction to retard your fall, so you feel nothing pressing against you, and thus you feel weightless..When in orbit around the Earth, an astronaut is in freefall, and is therefore weightless, but there is still gravity. When travelling between the Earth to the Moon, the astronaut is still in orbit around the Sun, and is therefore freefalling weightlessly.

Astronaut John Glenn was the first American to orbit the Earth on February 20, 1962, aboard the Friendship 7 spacecraft.
Michael Collins stayed in lunar orbit while Neil Armstrong and Buzz Aldrin walked on the moon.
Mass doesn't influence the orbit of a celestial body. Consider this: An astronaut aboard the Space Shuttle puts on a space-suit and steps outside for a 'space walk'. While he or she is out there ... inspecting the tiles or flexing the arm or whatever else they do out there ... the astronaut picks up both feet and floats free of the Shuttle for a few seconds. The astronaut and the Shuttle are both in earth orbit, and they stay together. They don't fly apart, even though the Shuttle's mass is thousands of times the astronaut's mass. As long as the orbiting body is small compared to the central body, the period of the orbit depends only on its size, not on the mass.

The third astronaut on Apollo 11 was Michael Collins. He piloted the command module while Neil Armstrong and Edwin "Buzz" Aldrin landed on the Moon. Collins remained in lunar orbit while Armstrong and Aldrin explored the lunar surface.
