WASHINGTON - NASA is celebrating the 41st anniversary of Earth Day this week with several online activities to engage the public in the agency's mission to use the vantage point of space to explore and protect our home planet.
One of the activities is a webchat on Earth Day, which is Friday, April 22. Scientists involved in an airborne campaign in Greenland to monitor Arctic ice cover will participate. NASA maintains the world's largest contingent of dedicated Earth scientists and engineers to lead and assist other agencies in preserving the planet's environment.
