As the world observes the 50th anniversary of Earth Day on Wednesday, April 22, NASA is highlighting the agency's many contributions to sustaining and improving our home planet's environment with a week of online events, stories and resources.
NASA's investment in space—both the unique Earth science we conduct from orbit and the technology we've developed by living in space and exploring our solar system and universe—is returning benefits every day to people around the world, particularly those who are working on environmental issues. From documenting Earth's changing climate to creating green technologies to save energy and natural resources, NASA is helping us all live more sustainably on our home planet and adapt to natural and human-caused changes.
Due to the ongoing COVID-19 pandemic, no in-person NASA activities are planned for Earth Day. However, NASA is bringing people together virtually for Earth Day with new online content, programming and activities, including an extensive array of at-home projects in the #EarthDayAtHome collection, which debuts Thursday, April 16.
NASA's observation of the Earth Day golden anniversary began on March 3 with a "50-Day Countdown" of daily social media posts highlighting many of the agency's Earth images and environmental projects. All of these posts are available on a blog updated daily on NASA's Earth Day website, which also includes a toolkit of activities for students and families. New content will be posted to the site beginning Monday, April 13. The NASA Earth Facebook account and @NASAEarth on Twitter and Instagram also will have special content through Earth Day.
Highlights of NASA Earth Day content and activities over the next two weeks:
