does going there and coming back to earth take the same time

3-4 days each way when you include the orbits needed to slow and make orbit or position for reentry.
Now directly they traveled about 15,000 mph and the distance to the moon is 238857 miles.
So a straight trip is 16 hours.
They had to travel in the path like a bell curve to make their approach behind the moon and enter an orbit first.
This required they travel 6 times further than a straight path.
The same physics of space flight applied returning to the earth.
Had they flown to intercept the moon straight on, they would not have been able to slow down without massive amounts of fuel. By approaching the moon from behind, the orbiter speed of the moon in from of them placed their speed in perfect position for the approach and orbit.
Think of two cars on the freeway one in front of the other.
The car in front is the moon and the car behind is the Apollo ship and its speed is faster than the speed of the moon car moving closer to intercept.
Same thing.
good question

Well it depends on the Spacecrafts velocity and power. The Saturn V rocket had the power to escaped Earth's orbit and also had 3 stages. So approximately 3-4 days. And the longest time you get to stay there is probably 3 days, Apollo 15,16, and ,17 all stayed 3 days exploring the moon (about 75 hours). And as with becoming an Astronaut you have to get a Bachelor's degree in Mathematics and Engineering. Or if you want to become a pilot you have to get at least 1,000 hours of flight. Good luck

Apollo astronauts supposedly needed 4 days to go to the moon a 4 back.but now with the ares rocket it will take 5 days cause that rocket has less power that the Saturn 5

Apollo 8 took 6 days to get to the moon and orbit around it. Roughly 3 days there and 3 days back.
In the case of Apollo 11, where Neil Armstrong & Edwin Aldrin the mission which included landing on the moon. It left earth on 16 July 1969, landed on the moon on 20 July 1969 and returned to earth on 24 July 1969.
The NASA website will give you details of all the apollo mission, unlike the conspiricy theorist who like to believe anything but the truth.

i would say that it takes around 6/7 days

If they fly with XL it would for ever.
