For the second year in a row, NASA is celebrating Earth Day in downtown Washington with two days of science presentations, displays, and hands-on demonstrations in Union Station. The events will be held April 21-22 in the station's Main Hall. All activities are free and open to the public.
On Monday, April 21, exhibits, displays and a variety of hands-on science demonstrations open at 11 a.m. and close at 5 p.m. EDT. These activities and displays continue on Earth Day, Tuesday, April 22, at 10 a.m. and remain open until 6 p.m. EDT. Also on April 22, a series of talks by NASA scientists and other speakers begins at 11 a.m. on the NASA Hyperwall stage.

Hands-On Demonstrations: April 21-22
Dynamic Planet -- This touchscreen interface allows users to drive a spherical display that shows a variety of remote-sensing satellite datasets.
Eyes on the Earth 3D: Come Fly with NASA -- A 3D visualization experience that lets users "fly along" with NASA's fleet of Earth science missions and observe climate data from a global perspective in an immersive, real-time environment.
What on Earth? -- Look closely at these Earth photos to determine just what on Earth it is. (April 22 only)
Space Racers -- A new animated television program following young Space Rocket cadets as they soar through the solar system learning about scientific investigation and observation, space exploration, and the importance of working together as a team. Visit the Space Racers Kiosk for an exclusive sneak peak of our new "Space Collector" game.
Science Casts -- Short videos about interesting and unusual science topics encountered by NASA's science missions. New episodes every week look into the science behind discoveries on Earth, the solar system, and beyond. Learn more at sciencecasts.nasa.gov.
iSat -- The Interactive Satellite Tracker is a browser-based application that allows you to track all NASA science satellite missions, as well as other satellites.
Calculate Your Carbon Footprint -- Discover where you fall on the "Green-o-Rometer." We’ll even offer simple tips on ways to reduce your carbon consumption.
UV-Detecting Beads -- NASA keeps a close eye on the sun’s ultraviolet (UV) radiation and you can too. Become a UV detective with specially designed UV-sensitive beads and walk away with your own UV-detection bracelet.
Learning Remote Sensing with Puzzles -- Help NASA piece together images taken of Earth from space, including the popular "Earth at Night" image.
Know Your Earth -- How well do you know your home planet? Take a quiz and earn a prize if you correctly answer each question. Through these quizzes, you can learn all about NASA Earth Science.
Digital Photo Booth -- Get your face in space and walk away with a real keepsake.
Earth Connection via Suborbital Platforms -- Navigate your way through NASA science and explore various research platforms using two touchscreen kiosks. Touch the materials used to make NASA's scientific balloons and inflate a cylinder made of the balloon film to observe how the material behaves while the cylinder expands.
The Earth Imagery Challenge -- NASA satellites are taking measurements of planet Earth from space every day. Follow our "clues" to solve the imagery mystery.
Sensors, Circuits, and Satellites -- Assemble an energy-sensing circuit and discover how NASA's Aura satellite studies the chemistry of our atmosphere.
Cloud in a Bottle: GLOBE Program -- Learn about clouds and make a cloud in a bottle. Then play our Cloud Cover Estimation game. (April 22 only)
Puzzling Changes in the Land -- Arrange a time series of Landsat images or piece together a Landsat scene to reveal Earth's changing landscape.
Aviation and the Environment -- What would happen to us if our atmosphere suddenly disappeared? Learn how pilots and astronauts protect themselves as they travel to the very edge of Earth's atmosphere.
Measuring Precipitation: On the Ground and From Space -- Learn how rain gauges work, how the technology of the new Global Precipitation Measurement (GPM) satellite measures precipitation from space, and why it's important to look at precipitation patterns around the globe.

NASA monitors Earth's vital signs from land, air and space with a fleet of satellites and ambitious airborne and ground-based observation campaigns. NASA develops new ways to observe and study Earth's interconnected natural systems with long-term data records and computer analysis tools to better see how our planet is changing. The agency shares this unique knowledge with the global community and works with institutions in the United States and around the world that contribute to understanding and protecting our home planet.
