A behind-the-scenes look at the math in NASA press releases
Problem 464: Big Moons and Small Planets!
Students work with a scaled drawing of 26 large moons in the solar system, and together with an exercise in using
simple fractions, explore the relative sizes of the moons compared to Earth.

Problem 463: A Simple Fuel Gauge in a Cylindrical Tank
Rockets use fuel tanks that can be approximated as cylinders. In this simple geometric exercise, students work
the formula for the volume of a cylinder to add a fuel gauge at the right level to indicate how much fuel remains.
