You would suffocate and die, assuming you were sucked out of a spaceship without a pressurized suit. Your organs and body would swell to 2-5 times normal size but not explode. If you could stay alive long enough you might experience various other issues, such as burning from direct sunlight, freezing from temperatures in space, and problems from decompression. Contrary to popular belief, your blood would not boil, and actually short exposures to space could be possible.
The presence or absence of spacecraft near Mars will have no effect whatsoever on the planet's gravitational field.
It's technically possible. But right now, there is no program, research, design, budget, funding, or planning going on to make it happen.
You can't you will probably fall in Jupiter and die. And why it's made of burring gases. so don't do it!
If a spacecraft traveling toward Mars experiences an engine shutdown, it would continue on its current trajectory due to inertia. The pull of Mars’ gravity would begin to influence the spacecraft, gradually pulling it closer to the planet as it approaches. Depending on its speed and trajectory, the spacecraft could either enter an orbit around Mars or collide with its surface. Ultimately, the gravitational pull of Mars would become the dominant force acting on the spacecraft.
The metal will rust.
Since the anvil is more than twice as massive as the astronaut, the astronaut will move much more rapidly than the anvil, as they both move in opposite directions following the astronauts push. And chances are, the massive anvil with then collide with the astronaut's spacecraft, doing horrendous damage, and the foolish astronaut will then be unable to safely return to Earth. So when you are in outer space, be careful with your anvil. I wouldn't go throwing it around at random.
If an astronaut falls ill in space, they would typically be treated using the medical equipment available onboard the spacecraft. The astronaut would also be in regular communication with medical staff on Earth who can provide guidance for treatment. In serious cases, the astronaut may need to be evacuated back to Earth for more advanced medical care.
If an astronaut's lifeline was cut, they would become untethered and float away into space. They would likely be unable to navigate back to their spacecraft and could be lost in space. Immediate action would need to be taken by the astronaut and their crew to retrieve them before they drift too far away.
the anvil will fall down
The gravitational pull between earth and the spacecraft will become insignificant.
Nothing.
Because without fun of some sort, an astronaut's life would be pure stress. Unless you relieve that stress, then you start impairing your performance. The same can happen with earthbound people who have high-stress jobs or are in high-stress situations.
it will continue to follow the motion of the satellite
He has a fit because of stress levels.
The force that can push a pilot out of an aircraft or spacecraft is known as centrifugal force. Centrifugal force is the outward force experienced by an object moving in a circular path, pushing the object away from the center of rotation. In the case of an aircraft or spacecraft making a sharp turn or maneuvering at high speeds, centrifugal force can potentially push the pilot out if they are not properly secured in their seat with restraints such as seat belts and harnesses. Pilots are trained to anticipate and counteract centrifugal forces to maintain control and prevent ejection from the aircraft or spacecraft.
The presence or absence of spacecraft near Mars will have no effect whatsoever on the planet's gravitational field.
Actually they already have visited a planet like the moon!
