NASA and Khan Academy, a non-profit educational website, have debuted a series of online tutorials designed to increase student interest in science, technology, engineering, and mathematics, or STEM. The announcement of the new collaborative effort was made today at the 6th annual White House Science Fair. The interactive education lessons invite users to become actively engaged in the scientific and mathematical protocols that NASA uses everyday to measure our universe, to explore the exciting engineering challenges involved in launching and landing spacecraft on Mars, and to learn about other space exploration endeavors and destinations.
