NASA centers across the nation invite journalists and the public to see and hear about the agency's efforts and contributions to understanding and protecting Earth.
Begun in 1970, Earth Day is the annual celebration of the environment and a time to assess work still needed to protect the natural resources of our planet. The agency maintains the largest contingent of dedicated Earth scientists and engineers in leading and assisting other agencies in preserving the planet's environment.

The Web site also features an online poll inviting the public to vote for the most important contribution NASA has made to exploring Earth and improving the way we live on our home planet. The "greatest hits" poll closes April 21. A new interactive feature will debut on Earth Day, April 22, that allows visitors to view a collection of astronaut photographs of Earth as seen from the current location of the International Space Station.
