US in rare bull's-eye for total solar eclipse on August 21

The sun, moon and Earth will line up perfectly in the cosmos on Aug. 21, turning day into night for a few wondrous minutes, its path crossing the U.S. from sea to shining sea for the first time in nearly a century.

Never will a total solar eclipse be so heavily viewed and studied - or celebrated.

"We're going to be looking at this event with unprecedented eyes," promises Alex Young, a solar physicist who is coordinating NASA's education and public outreach.

And the party planning is at full tilt from Oregon to South Carolina.

Eclipse Fests, StarFests, SolarFests, SolFests, Darkening of the SunFests, MoonshadowFests, EclipseCons, Eclipse Encounters and Star Parties are planned along the long but narrow path of totality, where the moon completely blots out the sun.

Vineyards, breweries, museums, parks, universities, stadiums - just about everybody is getting into the act.

The Astronomical League for amateur astronomers is holing up at Casper, Wyoming. Minor league baseball teams will halt play for "eclipse delays" in Salem, Oregon, and elsewhere. By a cosmic quirk of the calendar, the Little Green Men Days Festival will be in full swing in Kelly, Kentucky, as will the American Atheists' annual convention in North Charleston, South Carolina.

And where better to fill up on eclipse T-shirts and safety glasses - and eclipse burgers - than the Eclipse Kitchen in Makanda, Illinois.

Scientists are also going gaga.

"This is a really amazing chance to just open the public's eyes to wonder," says Montana State University's Angela Des Jardins, a physicist in charge of a NASA eclipse ballooning project . The student-launched, high-altitude balloons will beam back live video of the eclipse along the route.

Satellites and ground telescopes will also aim at the sun and at the moon's shadow cutting a swath some 60 to 70 miles wide (97 to 113 kilometers) across the land. Astronauts will do the same with cameras aboard the International Space Station. Ships and planes will also catch the action.

"It's going to be hard to beat, frankly," says Thomas Zurbuchen, head of NASA's science mission office.

At the same time, researchers and the just plain curious will watch how animals and plants react as darkness falls. It will resemble twilight and the temperature will drop 10 to 15 degrees.

Expect four hours of pageantry, from the time the sun begins to be eclipsed by the moon near Lincoln City, Oregon, until the time the moon's shadow vanishes near Charleston, South Carolina. NASA will emcee the whole show, via TV and internet from that coastal city.
