IntroductionHuman beings have studied the moon for millennia, watching its phases change and observing eclipses — both solar and lunar. During a solar eclipse, our moon moves between Earth and the sun and blocks the sunlight. In a lunar eclipse, Earth blocks the sun's light that normally lights up the moon, so we see Earth’s shadow over the face of the moon. From Earth, we see the moon get dark and often turn red. This happens because Earth's atmosphere scatters blue and green light while it bends yellow, orange and red wavelengths toward the moon.

    The moon is the most explored body in our solar system besides Earth, having been visited by numerous spacecraft from multiple space agencies around the world. It's also the only place besides Earth where human beings have set foot. Significant Events

    Media specialists tells stories across social media and help feature missions and people on TV and in films, books, magazines, and news sites. 



    Writers/producers capture the incredible stories of NASA's missions and people and share them with the world. 



    Administrators and directors work out of NASA headquarters, prioritizing science questions and seeking to expand the frontiers of discovery.



    Whether it's introducing kids to space or teaching physics to PhD candidates, educators help share their knowledge with the public.



    Engineers design and build all types of machines, from what a spacecraft looks like to the software that directs where a rover goes each day. 



    From an astrophysicist to a volcanologist, scientists of all types pose questions and help find answers to the mysteries of our universe.

    The important thing about being a scientist or an engineer is learning how to think critically, learning how to be creative, learning problem solving and learning how to learn.
