If he is fortunate enough to find a region of space that is still Newtonian, and the acceleration of gravity
is constant at 1,000G for a long distance and a fur piece, then he falls
X = 1/2 A t2
= 1/2 (1,000G) (60)2
= 1/2 (9,800) (3600)
= 17,640 kilometers in one minute,
= about 10,961 miles.
Notice that if he starts from rest, the average speed of his pulverized bones and distended guts
during the minute is 294,000 meters/sec,
or "Zero to 659,000 mph in 60 seconds." THAT oughta set you back in your seat !
The simple fact that they orbit Mars, suggests that they were captured by Mars' gravity.
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.
The planets are satellites of the sun. The moons are satellites of the planets. The moons revolve around the planets captured by their gravity, while the planets revolve around the sun captured by its gravity and the sun.
Yes. That's why they're in orbit (and not flying off in a straight line). Note - weight is the result of resisting gravity, NOT being in a gravity field.

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.
Gravity from objects such as the Earth, the Moon, the Sun, or the Milky Way will attract and accelerate an astronaut. "Accelerate" implies that the astronaut's velocity will change over time.If the astronaut is in free fall (basically, the spaceship's engine is not pushing the spacecraft), then the astronaut won't FEEL such gravity.
Weightlessness.

a bowling ball is much heavier than a astronaut under the action of gravity
Yes. The moon's surface gravity is about 1/6 what it is on Earth.
Gravity. No Gravity causes them to drift around and have no control over were they are going.

One example is how light an astronaut weighed when standing on the moon. As there is very little gravity on the moon, the astronaut was able to jump much higher than he could back on earth.
A good question, however to control gravity you would have to control time
I guess its the fact that you go into outerspace and there you have zero gravity and who doesn't like zero gravity?
they need to train in lots of zero gravity and engineering
