The Great Gravity Escape
Engineers and scientists make amazingly precise calculations so that a spacecraft's journey is timed exactly to reach the location where a planet will be at that time. Since Earth and Mars are always orbiting in their own paths, space travel from Earth to Mars might be compared to shooting a basketball into a moving hoop while standing on a moving platform. This requires that engineers think logically and use their math skills to forecast exactly where a planet will be located many months in the future.
