                    <h1>How are these sails propelled without fuel?</h1>
                    <p>
                        Because photons carry momentum, they impart a push when they bounce off a reflective
                        surface—just like any other colliding object. With the right design, this momentum can be
                        utilized to its fullest.

                    </p>
                    <p>The fact that these sails don’t need any fuel is incredibly helpful when it comes to long-range
                        missions. They can remain light, small, and travel for long periods of time without needing to
                        worry about refueling or mass.</p>

                    <h1>Reflective Surfaces</h1>
                    <p>Reflective surfaces tend to scatter light, meaning the photons are sent in all different
                        directions. Retro-reflective surfaces are able to perfectly reflect photons back the way they
                        came, maximizing the amount of momentum transferred from the light to the sail. Our team’s
                        light-sail design uses a particular retro-reflective polycarbonate material, allowing it to
                        harness as much momentum as possible.

                    <h1>The Sail's Shape</h1>
                    <p>Beyond the material, the shape of the sail also maximizes its sailing capabilities. Two nitinol
                        wires diagonally span the sail in an X-shape, unravelling a Miura fold upon deployment. The
                        Miura fold design keeps the sail compact when folded up, allowing it to fit in small deployers,
                        and lets it deploy much smoother than other fold designs. Cornell’s light-sail design is also
                        much smaller than designs of the past, at just 57.5 centimeters long and wide, 100 grams in
                        weight (including its ChipSats), and 0.04 millimeters thick. Its size means it can accelerate
                        and travel faster than ever before. </p>
