Target Audience:

General Public


NASA is joining schools, students, and science centers across the U.S. to celebrate one of the most well known and beloved numbers: pi. Pi Day gives us a reason to celebrate the mathematical wonder that helps NASA explore the universe. And we're giving students a chance to join in the fun by using pi to explore Earth and space themselves in our 2024 NASA Pi Day Challenge – available on Thursday, March 7.

In the meantime, explore our collection of evergreen Pi Day Challenge problems, articles about how we use pi at NASA, and free downloads, including mobile phone and desktop backgrounds.
