Quizplus · Accepted Answer

The laser beam should be aimed along your line of sight to the space station because the Earth's atmosphere refracts light and causes it to curve, which is known as atmospheric refraction. The curvature of the laser beam due to refraction will cancel out as the laser travels through the atmosphere and, thus, will hit the space station. Aiming the laser above or below your line of sight will cause it to miss the space station.
