NASA uses pi every day!
Pi is instrumental in developing the size of parachutes to land on the Red Planet. In fact, pi helps engineers determine how big the parachute needs to be in order to generate the drag needed to slow down craft landing on Mars. It also helps researchers map and explore Earth and planets in our own and other solar systems.
In this June 2017 photo, the supersonic parachute design that landed the Perseverance Mars rover on Mars on Feb. 18, 2021, underwent testing in a wind tunnel at NASA's Ames Research Center.
