Will I reach moon if I point my spacecraft towards it?
I mean simply drive forward as long as I can see the moon through my windshield glass.

answers:
Born Yesterday say: That depends on your spaceship's top speed.
In football, passers "lead" receivers because they
will move while the ball is in flight.
If you steer straight for the moon, you will have
to correct course continuously, because the moon is in motion.
(A few facts from the Wikipedia: On average, the distance to the Moon is about 385,000 km (239,000 mi) from Earth's center, which corresponds to about 60 Earth radii. With a mean orbital velocity of 1.022 km/s (2,290 mph), the Moon covers a distance approximately its diameter, or about half a degree on the celestial sphere, each hour.)
NASA usually "leads" it's targets like football players. They do pretty well.

spot a say: If you have enough fuel to continually correct your heading back towards the moon as it moves through space, it is one way to reach the moon but it is extremely inefficient
-
ideaquest say: The moon is not a stationary object.
-
say: No, the moon moves, so you would have to do some kind of fancy math or something beforehand. Also its important to remember that its gas on the right, brakes on the left.

Jeffrey K say: No. It doesn't work like that. Because of gravity from the earth and moon, your path gets curved. You must put yourself into an orbit that intersects the Moon's orbit. It requires some calculations with orbital mechanics.
-
Paula say: Yes.

But you really need some kind of trajectory

Joseph say: When you aim at the moving target you aim at not where the target is now but where it will be when your projectile arrives at the target. This is the lesson our earliest ancestors learned when they started throwing rocks to kill their prey but you seem to have failed to learn, thus wasting tens of thousands years of human evolution.

tham153 say: not the most fuel efficient way

RealPro say: Of course, eventually. It is pretty inefficient in terms of energy and time though.

john say: No, the moon is a moving target.

Morningfox say: That would take over twice the fuel compared to pointing in the best direction. To save fuel, you need to point where the moon will be when you get there.
