Celebrate Earth Day with NASA!

,One of the benefits we noted when man first was able observe the earth from above our atmosphere, from outer space, is that it enabled us to gain a new perspective on how very special our planet is. Viewed from a distance, it is obvious that we are all living in one global environment. And from a distance, this environment doesn't look as vast as it does from our vantage point on earth.

The land looks more precious, the seas less like unlimited places to discharge our wastes, and the atmosphere, less like a place to emit air pollution at night so no one sees it, to the fragile envelope which, more than anything, makes earth the special place it is.

Indeed, it is the atmosphere that permits life as we know it to flourish on earth. And we owe most of this new knowledge to the National Aeronautics and Space Administration (NASA)!

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. NASA maintains the world's largest contingent of dedicated Earth scientists and engineers in leading and assisting other agencies in preserving the planet's environment.

NASA celebrates the 40th anniversary of Earth Day on the National Mall in Washington beginning Saturday, April 17. Included in the events is the 'NASA Village,' which contains three domed tents, and will highlight the use of NASA science and technology to advance knowledge and awareness about our home planet and sustain our environment.

The NASA Science Tent which will host exhibits and hands-on demonstrations. The NASA Cinema Tent will feature multimedia presentations by NASA scientists and others. The NASA Technology Tent will present exhibits and demonstrations on a wide range of NASA environmental technologies.

Other events are also scheduled at NASA centers in California, Ohio, Maryland, Virginia, Alabama, and Mississippi:
