Celebrate Earth Day with NASA!

Celebrate Earth Day with NASA!

Earth Right Now

Your planet is changing, We're on it.

Like all things in life, Earth’s environment is in a constant state of flux. Components of the Earth system—including the atmosphere, hydrosphere, lithosphere, cryosphere, and biosphere—are all connected, and interact in complex ways that we do not fully understand. At NASA, our goal is to study the Earth as a system and understand how both natural and human-induced changes impact Earth’s environment over time.

To find out how our planet is changing and what NASA is doing to better understand and predict these changes, come celebrate Earth Day with NASA at Union Station in Washington, DC, April 21-22, 2014. NASA’s Hyperwall and Science Gallery exhibits will be on display, and a variety of hands-on demonstrations and activities will be located in the Main Hall. On Tuesday, April 22 (official Earth Day), nearly 20 NASA scientists will reveal the “big picture” to help tell fascinating science stories about our changing planet.
