Happy Pi Day: Can you solve NASA's space challenges?

Pi is essential for studying the universe, so NASA uses it often. Students can solve some real problems related to Pi that NASA had to deal with in the past.

 In honor of the mathematical constant pi – and its many uses in space exploration – the annual NASA Pi Day Challenge offers four math problems involving real NASA missions and science.
