Given that \( A \) and \( B \) are two points on the surface of a sphere with a radius of 5, and \( AB = 8 \). Planes \( O_1AB \) and \( O_2AB \) are perpendicular to each other and pass through \( AB \). The intersections of these planes with the sphere create cross-sections \(\odot O_1\) and \(\odot O_2\). Let the areas of \(\odot O_1\) and \(\odot O_2\) be denoted as \( S_1 \) and \( S_2 \) respectively. Solve for \( S_1 + S_2 \).
