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.
Are astronauts really 'weightless while in orbit why or why not?
The way we measure someone's weight with a scale, requires forces to compress/extend springs, etc.... On Earth, gravity pulls downward, the scale is stopped by the floor. When you step on the scale, you are applying the force of gravity on the scale, which measures the amount of stretch. In orbit, there is no resulting force for the scale to measure. The space ship is falling at the same speed as the astronaut and the scale. They can stand on the scale but it will ready ZERO. The astronauts have mass, its just that for a scale to work, you need a force which is being minimized by falling around the Earth (orbit)
Why did astronauts back in 1960s return to earth with muscles so weak that they had difficulty walking when they returned to the earth?
After any period in a place where the force of gravity is less than on the surface of the earth (or nearly weightless in orbit), muscles will begin to atrophy. The longer in space the weaker you get becuase the muscles do not have to counter the force of gravity. This also includes the heart muscle so the astronauts must be monitored while in space and for a while after their return to earth.
How many astronauts were in the first moon landing?
3. Neil Armstrong and Buzz Aldrin walked on the moon while Mike Collins stayed in orbit.
Why did the command and service modules stay in orbit around the moon?
The Lunar Module could not make the return trip to Earth and the CSM could not land on the moon. As such, the CSM stayed in orbit while the LM traveled to and from the lunar surface.
When astronauts float while in orbit because inertia and what are balanced in orbit?
Gravity

How much do satellites weigh?
Mass: 5.6846×1026 kg That's 95.152 Earths Hee Hee :P

Why do astronauts feel weightless while in orbit?
Astronauts in orbit are weightless, but not because they are beyond the pull of earth's gravity. If the moon, roughly 240,000 miles away, is within the influence of earth's gravity, so is an astronaut just a few miles up in comparison. Astronauts are weightless because they are in orbit, and being in orbit can be thought of very roughly as a special kind of freefall. They are held by gravity, but they are also moving along a path that keeps them from descending appreciably during their flight. If you remember clips you have seen of astronauts in the space station, floating freely, you can see how futile it would be to try to 'stand' on an ordinary house scale to measure how 'heavy' they are in pounds. But if you could sling an astronaut around on a kind of mass-measuring centrifuge (not too fast, of course) you would see that they are maintaining a healthy mass. Weight and mass are different measures, even if they seem to be indistinguishable on the earth's surface.

What did Neil Armstrong mean when he was heard to say he thinks he sees Santa Claus?
he was revering to a high speed light that passed by them while in orbit around earth . I believe they were going twice the speed of sound at the time. there's been several astronauts reports of UFOs' while orbiting earth not just US. astronauts. Russian astronauts for instance.
What do you do after sending a space shuttle up?
After a space shuttle is launched it goes in orbit around the Earth. While in orbit, the astronauts preform experiments that can only be done in micro gravity or preform maintenance on satellites, or launch new satellites.
What did astronauts live on the moon?
While on the moon the astronauts lived in their lunar module.
What are two ways a person can feel weightless?
A person can feel weightless when they are in free fall, such as during skydiving or bungee jumping. Additionally, astronauts can experience weightlessness when they are in orbit around Earth due to the lack of gravity.
Why did the command and service modules stay in orbit around the moon?
The Lunar Module could not make the return trip to Earth and the CSM could not land on the moon. As such, the CSM stayed in orbit while the LM traveled to and from the lunar surface.
