Is an astronaut circling the earth in a space capsule in not in the biosphere?

As the biosphere is contained entirely within the troposphere (lowest layer of the atmosphere), an astronaut in orbit is far over 100 miles above the highest portion of the biosphere.

If an astronaut is weightless orbiting the earth at 100 miles up would you experience weightlessness at the top of a 100 mile step ladder What equations would prove or disprove?
The person on the ladder would not feel weightless because they are not in orbit, they are simply at a high altitude. If they let go, they would fall straight down towards the earth's center just as any other object which is being pulled on by gravity.Orbit is achieved through velocity. With enough thrust, a rocket is able to propel an astronaut to a speed which will send him beyond the earth's gravitational field and straight into space (ie: "escape velocity"). However, by controlling the level of thrust and angle of inclination, the astronaut can be placed in an area of space that is somewhere "in-between" the pull of earth's gravity and the escape velocity. This is called "orbital velocity". The astronaut achieves ORBIT, and he is in a constant free-fall circling around the earth: not quite fast enough to escape the earth's gravity, but not so slow that he falls back to earth.When a spacecraft needs to return to earth, thrusters are fired in the direction of orbit, which decreases forward speed, and allows the craft to return to earth via the earth's gravitational field with help from atmospheric drag.
What anastronaut working in Space near the International space station says she feel weightless. What does she mean Does the astronaut no have weight?
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.

The highest satellite are about 5.6 earth radii from the centre of the earth .this is about a tenth of the way to the moon. what would be the force of gravity be on a50 kg astronaut at this location?
The force of gravity on Earth for this astronaut is 50 x 9.8 = 490 Newton. Divide this by 5.6 squared, and you get 15.6 Newton.Note that the astronaut will not feel this force, because he is in free fall; any space capsule he is in will accelerate towards Earth with the same speed as him, and he will feel weightless.
What is the portion of the Earth and atmosphere that supports life?
It is actually called the biosphere it is the part of the earth that can support life. That is why Earth is different than other planets, it's because we have a biosphere.
