In 1968 William Anders, an astronaut on the Apollo 8 mission, captured “Earthrise” — a photo of Earth appearing above the Moon’s horizon. The photo helped unite a generation to appreciate the fragility and beauty of our planet and inspire the first Earth Day less than two years later.
To mark the 50th anniversary of Earth Day, NASA is reflecting on what we’ve learned about our home planet. Chat with NASA scientists on Wednesday, April 22 from 6:00 a.m. to 1:00 p.m. EDT to find out how NASA satellites have changed our understanding of Earth, how different technologies have benefited the environment and how viewers can join NASA in observing Earth Day from home.
* Interviews will be conducted using video chat programs including Skype and Facetime *
NASA has been at the forefront of space exploration, from landing robots on Mars to sending humans into space. But one of NASA’s biggest fields of study is our planet, Earth. Of all the planets that NASA studies, none have matched the complexity of Earth. NASA’s Earth observing satellites provide a global mosaic of change over time. That coupled with observations from the air, sea and land provide a robust view of our dynamic planet.
NASA technology is all around us. The very technology that helps us understand planets in the solar system also helps us understand and protect Earth. NASA’s aeronautics division is using ‘spinoff’ technology right now to develop an all-electric aircraft that will make airline travel greener. Another division is testing a strong, lightweight composite material that will make wind turbines larger and more efficient.
