Solar Sailing
Explanation of solar sailing
Solar sailing is a propulsion method that harnesses the pressure of sunlight to generate thrust. It involves the use of large, lightweight sails made of highly reflective material. When sunlight strikes these sails, the photons transfer their momentum to the sail, creating a gentle but continuous push. As a result, the spacecraft gradually accelerates and changes its trajectory without relying on traditional engines or propellants.
How LightSail 2 used solar sailing to change its orbit
LightSail 2 utilized solar sailing to change its orbit by manipulating the force exerted by sunlight on its large, reflective sail. By determining the angle of the sail relative to the sun, the spacecraft was able to maximize the effect of the sunlight’s push in a specific direction. By adjusting its orientation, LightSail 2 could change the magnitude and direction of the force, allowing it to maneuver and alter its orbit as desired.
The gentle push of sunlight and its effect on the spacecraft’s movement
While the force exerted by sunlight may seem minuscule, its cumulative effect over time can significantly impact a spacecraft’s movement. Although each photon carries a tiny amount of momentum, the continuous bombardment of photons on the solar sail creates a constant thrust that gradually accelerates the spacecraft. This gentle push from sunlight enables the spacecraft to make precise adjustments to its trajectory and allows for more efficient propulsion, resulting in smooth and controlled movement through space.
