Space travel involves enormous distances and a commonly used mathematics methods like trigonometry are especially helpful to calculate the distances between planets, stars and galaxies that are measured in millions and millions of miles. In fact, these distances are so large that distance is often referred to in light years. Astronauts use math to calculate orbital trajectories, ensuring spacecraft stay on course and return to Earth safely. For example, they must calculate how much fuel is needed to reach the International Space Station or how to adjust their path if they encounter obstacles. Math is therefore, the essential force behind successful space missions, guiding astronauts, calculating trajectories, and enabling safe exploration beyond Earth.
