While playing darts, you aim your dart to an exact point on the dart board. Or else, you will probably miss the target. But this won’t work for a spacecraft if it is to land on the Moon. Wonder why?
Your dart board is a stationary object while the Moon is always in motion. In addition to that, a spacecraft always travels in a curve. Therefore the scientists always aim for a point in space. But they do not choose a random point. They calculate the time that the Moon would take to reach the exact point.
