In this illustrated problem set, students use pi to compare the sizes of Mars landing areas, calculate the length of a year for a distant solar system object, measure the depth of the ocean from an airplane, and determine the diameter of a debris disk.

In this illustrated math problem, students use pi to compare the area of the Hubble Space Telescope and Webb Telescope’s primary mirror.

In this illustrated problem set, students use pi to calculate the size of a Mars rock sample, compare the mirrors of two space telescopes, deduce an asteroid's makeup, and size up a solar eclipse.

In this illustrated problem set, students use pi to collect samples from an asteroid, fly a helicopter on Mars for the first time, find efficient ways to talk with distant spacecraft, and study the forces behind Earth's beautiful auroras.

In this illustrated problem set, students use pi to detect frost in lunar craters, determine the density of Mars' liquid core, calculate the powered output from a dam, and find out how far a spacecraft travels as it returns data to Earth.

In this illustrated problem set, students use pi like NASA scientists and engineers working on space communications, and Earth, Moon, and asteroid science.

In this illustrated math problem, students use pi to calculate the position of Earth in orbit as a signal is sent from a spacecraft in deep space.

In this illustrated math problem, students use the mathematical constant pi to figure out how much data a spacecraft collects every day.

In this illustrated math problem, students use the mathematical constant pi to find the "habitable zone" around a distant star and determine which of its planets are in that zone.
